Splenic angiosarcoma is a rare neoplasm that often remains asymptomatic till the onset of massive intra abdominal bleeding that require emergency splenectomy. We report here a case of 60 year old male who presented with on and off fever and a splenomegaly was found on clinical examination suggesting a lymphoproliferative disorder. A contrast enhanced computerized tomography suggested splenic trauma with intracapsular bleed. A splenectomy was carried out that revealed splenic angiosarcoma. Splenomegaly and fever is a very rare presentation of angiosarcoma. Though rare it should be kept in mind when investigating pyrexia of unknown origin.

| Introduction|| |
Angiosarcoma is a rare malignant neoplasm of endothelial cells, which represents less than 2% of all soft tissue sarcomas. Despite primary angiosarcoma of spleen being extremely rare, it is the most common primary nonlymphoid malignant lesion of spleen. Till date only 200 cases have been reported.  Here we report a case of primary angiosarcoma of spleen presenting as on and off fever and anemia.
| Case Report|| |
A 60-year-old male presented with complaints of on and off fever and lump in left upper abdomen of 1 month duration. Physical examination revealed pallor. Abdomen was soft, with no venous engorgement. There was a 10 × 7 cm lump; 5 cm below left costal margin in midclavicular line. The lump was nontender with smooth surface and sharp margins. Bowel sounds were present. Laboratory evaluation showed anemia and leukocytosis; electrolyte and liver function tests were with in normal limits.
General blood picture was suggestive of hemolytic anemia with spherocytes, target cells, and Howell-Jolly bodies More Details. Chest X-ray, X-ray abdomen, and echocardiogram were unremarkable. Upper gastrointestinal endoscopy showed antral gastritis, suggesting segmental portal hypertension. Abdominal sonography and computed tomography (CT) showed splenomegaly with heterogeneous enlargement, subcapsular hematoma with multiple ill-defined nodules in the splenic parenchyma with minimal ascites, and left pleural effusion [Figure 1].

Suspecting a splenic trauma in a congested enlarged spleen, a laparotomy with splenectomy was performed. On gross examination, spleen was enlarged in size with cut surface showing a circumscribed grey white area with diffuse hemorrhagic areas and multiple ill-defined nodules [Figure 2]. Microscopic examination showed the replacement of whole of the spleen by a vascular neoplasm composed of anastomosing vascular channels lined by atypical endothelial cells. Tumor was composed of solid areas and papillary fronds. These papillary fronds were lined by pleomorphic endothelial cells with pleomorphic hyperchromatic nuclei showing mitotic figures [Figure 3] and [Figure 4]. Areas of necrosis were also noted. The staining for CD31 was performed, which showed diffuse membranous positivity [Figure 5]. Based on these findings the diagnosis of angiosarcoma was made.

| Discussion|| |
Primary angiosarcoma is an extremely rare neoplasm with reported incidence of 0.14-0.23 cases per million.  It may develop at any age, however, the mean age at presentation reported in the literature is 59 years ranging from 14 months to 89 years ,, with a slight predominance in men.
Clinical presentation range from asymptomatic disease to splenic rupture and lethal hemorrhage. Splenic rupture occurs in 13%-32% of patients and presents as the most serious manifestation in most of the cases. It is the worst prognostic factor because it puts the patient at an increased risk of peritoneal dissemination. Fever as an associated symptom has been observed in nearly 10% of the patients with angiosarcoma.  Sun et al. investigated splenectomy in 35 patients of pyrexia of unknown origin and found 1 case (2.9%) of splenic angiosarcoma.  It was the most common feature in the series of Sordillo et al. (1981), where it was present in almost all of the 4 cases.  Hemolytic anemia with angiosarcoma has been previously reported in a patient with vinyl chloride exposure,  it was also present in 3 out of 4 cases in the series of Sordillo et al.
Radiologically, splenic angiosarcoma presents as splenomegaly; with solitary or multiple heterogeneous mass lesions with increased echogenecity and poor margins. Associated hepatic lesions or retroperitoneal lymph node enlargement may also be seen.  Besides these a subcapsular hematoma was also identified on ultrasonography in our case; however, CT scan abdomen showed a characteristic picture consisting of splenomegaly with heterogeneous contrast enhancement and subcapsular hematoma with multiple ill-defined nodules in the splenic parenchyma, suggesting a diagnosis of splenic angiosarcoma with subcapsular rupture of the spleen. Radiologically, splenic angiosarcoma mimic portal hypertension at times, only 1 case of primary hemangiosarcoma associated with documented portal hypertension and functional splenic aplasia has been reported in the literature. 
Exploratory laparotomy with splenectomy provides tissue diagnosis. Polydrug chemotherapy, including doxorubicin, daunorubicin, and vincristine, has been proposed to offer benefit.  Megavoltage radiotherapy is used for symptomatic palliation of bone metastasis. 
Primary angiosarcoma of spleen is a very aggressive neoplasm with high metastatic rate and poor prognosis with mean survival time 10.3-14.4 months.  Concomitant malignancies are found in 5% of the patients and include carcinoma breast; colorectal carcinoma and non-Hodgkin's lymphoma. 
| Conclusions|| |
Splenic angiosarcoma is a rare tumor of the spleen and often mimic splenic trauma and hemorrhage, high degree of suspicion, and a laparotomy with splenectomy often helps in establishing the diagnosis. The role of chemotherapy and radiotherapy has not been established. Presentation as segmental portal hypertension and anemia is rare.
