Context: Lymphoma was the second most common malignancy accounted for 22% of pediatric cases, of which 34 (68%) were non-Hodgkin's lymphoma (NHL). Aims: To find the incidence, clinical presentations, laboratory findings, proportion of extranodal involvement, and to study histological subtypes (REAL/WHO classification) of NHL, compare them with reported case series in the world literature. Settings and Design: Gross specimens and biopsies of pediatric NHL were retrieved from the Department of Surgical Pathology from the year 2004 to 2013 at a tertiary care hospital. Patients and Methods: Gross and microscopy of incisional biopsies and surgically resected specimens of pediatric cases were studied using hematoxylin and eosin stain and wherever needed special stain and immunohistochemistry were used. Results: The incidence of NHL was higher in more than 10 years of age group with male predominance. Burkitt's lymphoma (BL) (41.2%) was the most common subtype followed by T-lymphoblastic lymphoma (T-LL) (29.4%). Predominantly extranodal presentation was seen, BL presented as ileocecal masses (five cases) and orbital swelling (three cases). T-LL presented as a mediastinal masses (six cases). Rare cases of precursor B-LL involving orbital mass and plasmablastic lymphoma involving paranasal sinuses were studied. Among bone marrows studied a case of T-LL developed pancytopenia, during chemotherapy showed giant pronormoblast (Parvovirus infection). HIV association was seen in five cases of NHL. Postchemotherapy disease-free survival was very low and many patients died during chemotherapy. Conclusion: Although the incidence of HL is higher in children, in the present study, NHL with extranodal presentation (58%) involving rare sites with poor prognosis is higher, 15% of all cases showed HIV seropositivity.

  Introduction Top

The incidence of pediatric tumors is on rise worldwide.[1] In developing countries like India, childhood mortality is still due to malnutrition and infections, but pediatric tumors are also rising in number [1],[2] Lymphomas are the third most common group of malignancies in children and adolescents in the USA.[3] Non-Hodgkin lymphoma (NHL) accounts for approximately 7% of newly diagnosed cancers.[4] NHL constitutes 6%–10% of all pediatric malignancies in different parts of the world.[5],[6]

This study looks into various NHLs causing mortality and morbidity in children and their distribution according to age and sex.

Study design

Selection and description of participants

In this study, 34 cases of NHL retrieved from surgical pathology were studied from 2004 to 2013. It is a retrospective and prospective study.

Inclusion criteria

Cases of pediatric NHL reported in the Department of Surgical Pathology age up to 15 years including males and females.

Exclusion criteria

Age above 15 years.

Gross and microscopic study of incisional biopsies and surgically resected specimens done using H and E stain and wherever required special stains, IHC. Furthermore, cases are analyzed according to age, sex, and clinical features. Retrospectively, surgically resected and biopsied cases of pediatric NHL were studied by using clinical data from record sheets and reviewing slides and paraffin blocks. Detailed clinical history was obtained from the indoor papers from medical record office.

Morphological features of external and cut surfaces of the organs were documented and they were preserved in 10% formalin for adequate fixation. After fixation, adequate sections from each of the organs were taken. Sections were studied by using H and E stain and IHC.

Radiological findings (computed tomography [CT], magnetic resonance imaging [MRI], X-ray, and ultrasonography [USG]) and complete blood count with other laboratory investigations were retrieved from the indoor papers. Subtyping of lymphomas was done with the help of IHC.

Clinical information obtained from patients medical records included as follows:

  1. Patients age, sex, and chief complaints
  2. Physical examination:

    1. Lymphadenopathy – localized/generalized
    2. Hepatosplenomegaly
    3. Abdominal mass
    4. Gastrointestinal involvement
    5. Mediastinal involvement
    6. Any other site involvement

  3. Radiological findings

  Results Top

During the study 4302 pediatric cases up to the age of 15 years from the year 2004 to 2013 were retrieved, constituting 5.6% of all. The incidence of pediatric malignancies was 5.2% (227) of all pediatric cases, and incidence of pediatric lymphoma was found to be 22% (50) of all pediatric malignancies [Figure 1]. Among these, central nervous system (CNS) tumors (43%) were the most common followed by lymphoma (22%), of which NHL constitutes 15% (34) cases [Figure 2]. Among NHL, Burkitt's lymphoma (BL) was the most common 14 cases (41.2%) followed by lymphoblastic lymphoma (LL) 11 cases (32.3%), two cases of anaplastic large-cell lymphoma (ALCL) and one case of plasmablastic lymphoma were reported. Six cases of NHL were unclassified due to unavailability of tissue blocks for further subtyping [Table 1] and [Figure 3].

Majority of the cases were found in Stage 2 and 3, constituting 23 cases (68%) suggestive of the widespread involvement of disease at the time of diagnosis.

In the present study, NHL showed predominantly extranodal involvement.

Five cases of BL showed gastrointestinal involvement, the most common site was small bowl (ileocecal). Three cases presented as orbital mass, one case showed paraspinal soft-tissue swelling at D4–D5 level, and another as tibial swelling with extensive abdominal and mediastinal deposits [Table 4].

Maximum cases of BL found in Stage 3 and 4. Four of 14 cases were HIV seropositive, showed poor prognosis, and died during the treatment course.

Six cases of T-LL presented with mediastinal widening due to mediastinal mass and lymphadenopathy, of which in three cases pleural and pericardial fluid were positive for malignant cells on fluid cytology [Table 4].

One of the cases of T-LL showed CNS involvement with CSF positive for malignant cells and extensive pleural, pericardial, and abdominal involvement, while another showed extensive bone marrow involvement with 80% of blast.

One case of B-LL showed bilateral large lobulated intraorbital mass occupying the retrobulbar portion, orbital apex, and extending into the cavernous sinus. The mass was encasing the optic nerve and the patient died during the treatment.

Two cases of ALCL presented as paraspinal masses, one patient presented as fever, weight loss, and back pain with spinal cord lesion died during therapy. Another patient presented as multiple lymph node enlargement with visceral deposits.

A 14-year-old male child presented with left side nasal obstruction for 3 months with epistaxis, 3–4 episodes. CT skull and nasal cavity showed soft-tissue lesion involving left nasal cavity extending into maxilla, sphenoid and ethmoid sinus, and sparing left orbit. On histopathological examination and immunohistochemistry, the patient was diagnosed with plasmablastic lymphoma and the patient died during therapy.

Cases showed the involvement of the kidney, parotid glands, testis, and liver by neoplastic lymphoid cells which are not common. Visceral presentation is more common compared to nodal, later found only in 3 cases.

A higher incidence of NHL is seen in HIV-positive cases, with predominant subtype being BL [Table 5].

On laboratory testing, NHL cases showed decreased levels of hemoglobin, while no significant change was found in total leukocyte count or platelet count, while serum LDH and serum B2 Microglobulin were significantly raised in the majority of cases.

  Discussion Top

Lymphoma has been reported as the second or third most common childhood malignancy in India,[7] and other countries;[7] similarly in this study, it was the second most common pediatric malignancy after CNS tumors.

In the present study, the incidence of pediatric lymphoma was 22% of all pediatric malignancies, which is comparable with studies conducted by (24.2%) Jabeen et al.,[8] (20.3%) Swaminathan et al.[9]

Srinivas et al. (2002)[10] have reported the incidence of NHL 10%–13% which is comparable with present study (15%), while Swaminathan et al.[9] have reported it lower (8.4%).

Incidence of NHL was higher (44.1%) in age group more than 10 years, which is comparable (60%) with the study conducted by Manipadam et al.[7]

M: F ratio in the present study (2:1) is comparable with the studies conducted by Manipadam et al.[7] (2.87:1), Wright et al.[11] (2.7:1), and Nandakumar et al.[12] (2.5:1) under 15 years of age group reported from India.

Manipadam et al.[7] have reported most of the NHL subtypes showed a marked male predominance except ALCL, which showed gender equality.

Wright et al., UK,[11] Hwang et al., Korea,[13] and Burkhardt et al., Germany [14] reported BL as the most common NHL subtype which is similar to the present study, while Manipadam et al., India [7] and Srinivas et al., (1983) India [10] reported LL as the most common NHL subtype and BL as the second most common.

Incidence of extranodal presentation 67.5% (mediastinal and gastrointestinal) in absence of peripheral lymphadenopathy is much higher in the present study compared to previous study done by Srinivas et al. (1983)[10] (32%) and Manipadam et al.[7] (52%).

Majority of the cases of BL showed abdominal (ileocecal) 64.2% similar to reported by Advani et al.[15] (70%) and Srinivas et al.[10] (85.7%). Furthermore, 72.2% of cases of LL showed mediastinal involvement similar to studies done by Advani et al.[15] (65%).

HIV associated Non-Hodgkin's lymphoma

BL is a highly aggressive lymphoma and its association with seropositivity and immunosupression is known. In the present study, four of 14 cases of BL and one case of LL studies were HIV seropositive, whereas Manipadam et al.[7] reported only one patient with HIV infection and diagnosed with BL.

Burkitt's lymphoma

Magrath [16] reported Burkkit's lymphoma is biologically heterogeneous, has become notorious due to its high incidence in individuals infected with HIV, which is providing a second, potentially fertile model for the exploration of the pathogenesis of lymphoid neoplasms. In the present study, four of 14 cases diagnosed with BL were HIV seropositive.

Lymphoblastic lymphoma

Manipadam et al.[7] reported 61.7% of LL cases, mode of presentation was peripheral lymph node enlargement and only 33.3% of the cases had involvement of mediastinum, while in the present study significantly higher no of cases showed mediastinal involvement.

A 6-year-old girl presented with gradually increasing proptosis of left eye over 6 months [Figure 4]. On examination she had proptosis of the eye with eyelid edema, vision, and pupillary reflexes were preserved, no papilledema. MRI brain and orbit showed fairly large lobulated intraorbital mass occupying the retrobulbar portion, orbital apex which was extending into the cavernous sinus [Figure 5].

Resection of the mass was done. Intraoperatively tumor was well circumscribed, not involving the optic nerve. Histopathological examination showed bits of tumor tissue showing diffuse dense monomorphous proliferation of lymphoid cells, infiltrating in the orbital soft tissue and muscle, and tumor cells were medium-sized lymphoid cells with thin nuclear membrane, delicate chromatin, indistinct nucleoli, brisk mitoses, and scant cytoplasm. On immunohistochemistry, tumor cells were negative for desmin, mic2, MPO, and synaptophysin and positive for LCA, CD20 and Tdt [Figure 6].

Final diagnosis–Primary orbital precursor B-cell lymphoblastic lymphoma.

The patient was started with systemic chemotherapy and died during the treatment course.

Similar cases of primary ocular adnexal lymphomas in younger age group of 7–12 years presenting as proptosis with loss of vision due to unilateral orbital mass involving optic nerve extending into anterior cranial fossa have been reported by Ferry et al.,[17] Alford et al.,[18] and Hari Mohan et al.[19]

A 14-year-old male child presented with left side nasal obstruction for 3 months with epistaxis, 3–4 episodes. CT skull and nasal cavity showed soft-tissue lesion involving left nasal cavity extending into maxilla, sphenoid and ethmoid sinus, and sparing left orbit. Resection of the mass was done [Figure 7].

On histopathological examination, soft-tissue tumor showed the monomorphic population of large plasmablastic cells with abundant basophilic cytoplasm. Round to ovoid vesicular nuclei with prominent peripheral-based nucleoli. Prominent tingible body macrophages seen imparting a starry-sky appearance with prominent mitotic activity suggestive of plasmablastic lymphoma.

Dignosis was confirmed on IHC and tumor cells were positive for CD138, EMA, LCA, and negative for CD20, CD56, CK, S100, NSE, synaptophysin, and chromogranin [Figure 8].

Plasmablastic lymphoma is a rare and rapidly progressive variety of DLBL that was originally reported exclusively in the jaw and oral mucosa of male-predominant HIV-positive patients. A substantial minority of cases occur in HIV-negative patients following solid organ transplantation or immunosuppressive therapy.

Christine et al.[20] have reported a 24-year-old male presented with chronic sinusitis, pain in the left cheek, and left-sided facial asymmetry for 2 months. CT scan showed left maxillary sinus mass, involving the nasal septum, and extending through the medial maxillary sinus wall into the left nasal canal. The mass also invaded the inferior orbital rim and abutted the inferior rectus muscle. Biopsy of the mass revealed a monotonous, highly proliferative sheet of mononuclear cells, and IHC studies diagnosed plasmablastic lymphoma.

In the present study, a 10-year-old male child presented with fever, cough, and chest pain with repeated hemorrhagic pleural and pericardial effusion. USG chest showed moderate-to-severe pericardial and pleural effusion with right-sided lung collapse. CT chest showed a mediastinal mass. Pleural fluid cytology showed atypical round cells suggestive of lymphoma.

Histopathological examination and IHC on lymph node biopsy were conducted and diagnosed with T-LL.

Patient was started with chemotherapy, during the treatment course developed pancytopenia for which bone marrow examination was conducted.

Bone marrow aspirate showed erythroblastopenia with giant pronormoblast with 14% lymphomonocytoid cells suggestive of parvovirus infection [Figure 9]. The patient was detected with raised titers of immunoglobulin M parvovirus antibodies and diagnosis was confirmed with serology.

Parvovirus B19 infection causes severe cytopenia and can mimic a leukemic relapse or therapy-induced cytopenia in patients with hematologic malignancies, and Hence, screening for parvovirus B19 DNA by polymerase chain reaction (PCR) in pediatric patients with ALL and unexplained cytopenia is suggested. Detection of giant pronormoblasts and absence of normal mature erythroid precursors is characteristic of parvovirus infection, on a routine bone marrow examination.

Lindblom et al., USA [21] reported among 117 children with ALL, 18 (15%) were found to be parvovirus B19 DNA positive, while the infection was suspected on clinical grounds in only one of these 18 patients.

Yetgin et al., Turkey [22] reported two cases of parvovirus B19 infection and bone marrow infiltration with preBlymphoblasts, one patient was diagnosed with ALL, and the other patient with neurologic findings, showed total resolution of the blastic morphology and phenotype.

McNall, USA [23] described a patient undergoing induction therapy for ALL whose parvovirus B19 infection was identified by the incidental bone marrow examination.

Immunocompromised children including those undergoing chemotherapy treatment of malignant disease, are at particular risk for infection with parvovirusB19, immunoglobulin therapy can revert this changes, this highlights the importance of alertness to the possibility of parvovirus infection in children with cancer.

In the present study, three cases presented as orbital swelling with intracranial extension, 3-year-old male child presented with unilateral proptosis, headache, and decreased vision. CT scan showed soft-tissue lesion involving orbit, small bowl thickening with mesenteric lymphadenopathy. The child was diagnosed with secondary involvement of orbit with primary gastrointestinal BL.

Zak et al.[24] reported a case of non-African BL presenting an acute bilateral fulminant exophthalmos in as infantile male, correlates with the present study.

Huisman et al.[25] reported a 12-year-old boy who presented with incomplete right ophthalmoplegia, exophthalmos, and headache diagnosed with BL on mediastinal LN biopsy.

  Conclusion Top

The incidence of pediatric tumors is increasing worldwide. Although malignant neoplasms are rare in children, it is an important cause of childhood mortality in many of the economically developed nations of the world. Due to the major advances in diagnosis, multimodality therapy, development of the rational use of combination chemotherapy, and improved supportive care, the cure rate in childhood cancer has increased tremendously and over 60% of all childhood cancers are now curable.

Among childhood malignancies, lymphomas contribute the second most common. Although the incidence of Hodgkin's lymphoma was higher in pediatric age group, number of NHL cases is rising rapidly due to increased prevalence of HIV patients, immunodeficiency, and many undiagnosed etiologies. Disease-free survival period is very less in majority of NHL patients with predominantly extranodal visceral involvement, as many of them died during chemoradiation.

Clinical and histopathological study of these cases helps in knowing their epidemiology and burden of disease in the community. With a careful assessment of histomorphological features along with clinical and radiological imaging information, accurate diagnosis of NHL is possible. Although conventional H and E can diagnose the lymphomas, IHC plays an important role in further subtyping of lymphoma.

Parvovirus B19 infection causes severe cytopenia and can mimic therapy-induced cytopenia in lymphoma patients, and hence, screening for parvovirus B19 DNA by PCR in lymphoma patients on therapy with unexplained cytopenia is suggested. Detection of giant pronormoblasts and absence of normal mature erythroid precursors is characteristic of parvovirus infection on routine bone marrow examination.
