ABSTRACT
A 25-year old man with hematuria had a polypoid tumor of the urinary bladder which was diagnosed as transitional cell carcinoma (TCC) on transurethral resection with partial cystectomy. One year following post-operative radiotherapy, he had to undergo surgery for intestinal perforation. On laparotomy the recurrent tumor had involved pelvic organs and sigmoid colon. It now showed predominantly osteogenic sarcoma on histopathologic examination. The case is reported in view of rarity of primary osteogenic sarcoma in the urinary bladder.

Epithelioid haemangioendothelioma is a rare primary malignant tumour of the bone that accounts for less than 1% of all primary bone malignancies. The case discussed here is of a 35 years old male who presented with gradually increasing left infrascapular mass attached to 10th rib. X-ray showed an expansile lytic lesion in 10th rib. On FNA the diagnOsis of fibrous dysplasia or fibrous-histiocytic lesions was suggested. The lesion was excised along with adjacent rib. Histopathological examination showed features of epithelioid haemangioendothelioma. Immunohistochemistry revealed focal factor VIII related antigen positivity.

Acute erythroleukemia is a relatively rare form of acute myelogenous leukemia. In the present study we analysed ten cases of acute erythroleukemia. All the patients were anemic and nine were thrombocytopenic at the time of diagnosis. Peripheral blood showed blasts in nine cases. Dyserythropoiesis was seen in all the cases whereas dysmegakaryopoiesis was seen in five cases. Dysplasia in the granulocytic series was seen in five cases. Based on the overall features this study concludes that acute erythroleukemia is associated with dysplasia of variable degree.
