Background : Primary Gastric Non- Hodgkin's Lymphomas (NHL) are being increasingly encountered in the recent years. While the role of Helicobacter pylori (H. pylori) has been explored in its causation, some studies have suggested the role of the Epstein - Barr virus (EBV). However data from India is not readily available and this prompted us to study the morphology of primary gastric NHL, the prevalence of EBV infection in primary Gastric NHL and study its association with H. pylori infection. Materials & Methods : A retrospective study. Sixteen biopsy proven cases of primary gastric NHL were studied. Histologic features were reviewed. Immunohistochemistry for EBV LMP-1 and Modified Giemsa stain to identify Helicobacter pylori were done. Results : There were 10 low-grade and 6 highgrade lymphomas, 15 of them classifiable as Mucosa-associated lymphoid tissue (MALT) type, owing to the presence of lymphoepithelial lesions. 36% of the cases were EBV positive. Only one case showed H. pylori. 4 patients succumbed to the disease, of which 3 were seropositive for HIV. Conclusion : Our pilot study suggests that EBV may have an important role in the pathogenesis of gastric MALT lymphomas. The significance of this association and its prognostic value need to be explored in larger number of patients.

Primary non-epithelial malignancies of the penis are rare. We report a patient with an unusual presentation of an unexpected spindle cell malignancy at this site. A 35- year-old man presented with a mass in the shaft of the penis with inguinal lymphadenopathy. A malignant spindle cell neoplasm was seen involving the corpora, consistent with leiomyosarcoma. Immunohistochemically, the tumour was positive for S100, HMB-45 and negative for SMA. A final diagnosis of amelanotic spindle cell melanoma was made. This case is being presented to reiterate the importance of including melanoma in the differential diagnosis of spindle cell sarcomas at uncommon sites.

Myofibroblastoma of breast is an extremely rare mesenchymal lesion comprising of myofibroblasts. Less than 70 cases have been reported in the literature. Though many histological variants are known, characteristic morphological, cytologic, immunohistochemical and ultrastructural features help to differentiate it from other spindle cell lesions of breast. Here we report an epitheloid variant of myofibroblastoma breast in a 55-year-old female. Though CD34 showed only focal positivity, typical morphological and other immunohistochemical features helped in arriving at the diagnosis.

A 7-month-old female child was admitted with a short history of bleeding and mass protruding from the vagina. Alfa-feto protein levels were raised. Biopsy taken of the tumour mass was suggestive of Endodermal sinus tumour (yolk sac) of vagina. Neoadjuvant chemotherapy was given. Organ preserving resection of tumour was done successfully.

A 20 year old female presented with swelling of right cheek and complete loss of vision in her right eye for 6 months. Lower motor neuron (LMN) palsy of facial (VII) nerve was evident. CECT scan suggested an illdefined non-enhancing mass lesion in right infratemporal fossa. The mass was excised. Histopathology confirmed diagnosis of myoepithelial carcinoma. Following surgery, patient received adjuvant chemotherapy and radiotherapy. Myoepithelial carcinoma of soft tissue is rare, and has been recognised recently. The case is being reported on account of its rarity.
