Abstract:

Cutaneous leiomyosarcoma is a relatively rare tumor accounts for about 2-3% of superficial soft tissue sarcomas. It occurs more frequently in males in fifth and sixth decades with a predilection for extremities. We report a 27 years old male with cutaneous leiomyosarcoma of thigh, previously diagnosed as pleomorphicfibroma. The tumor composed of pleomorphic spindle shaped cells with blunt ended nuclei and high mitotic activity. Smooth muscle actin was positive. In this case, the young age of the patient and previous misdiagnosis of the tumor are interesting. Subtle histologic features of low grade leiomyosarcoma can be a pitfall in diagnosis and so affects the optimal management of the patient as it occurred in previous sample of this case.

Splenic abscess due to chronic melioidosis in a patient previously misdiagnosed as tuberculosis

Melioidosis is endemic in Southeast Asia and Northern Australia. Sporadic cases have been reported from many parts of the world where it has an epidemic potential with high-rate fatality cases. In non-endemic areas, melioidosis may be misdiagnosed with common diseases and this may prove fatal. Sporadic cases of melioidosis are mistaken for tuberculosis in India. We report a case of splenic absc...

A rare case of cutaneous leiomyosarcoma in budgerigar (Melopsittacus undulatus)

  Leiomyosarcoma in birds is relatively rare. This tumor as a muscle neoplasm was reported in captive and free ranging birds. Smooth muscle cells may develop to the leiomyosracoma, but splenic smooth muscle trabeculae is most common site of the tumor growth. Although budgerigars have an incidence of neoplastic diseases but smooth muscle tumors were rarely reported in this species. To the best o...

Chromoblastomycosis due to Fonsecaea monophora misdiagnosed as sporotrichosis and cutaneous tuberculosis in a pulmonary tuberculosis patient

Chromoblastomycosis is caused by dematiaceous fungi. It develops after inoculation of the organism into the skin. We report a case of chromoblastomycosis in a pulmonary tuberculosis patient without known history of trauma. The lesions were initially diagnosed as sporotrichosis and skin tuberculosis. Histopathology of scales and skin biopsy specimen revealed sclerotic bodies, the hallmark of chr...

Primary Pulmonary Vein Leiomyosarcoma: A Case Report

Primary leiomyosarcoma of the heart is extremely rare and found in about 0.2% of all cardiac tumors. Here in a 26-year-old man with progressive dyspnea, which had started since 2 months ago, is presented. Echocardiography revealed a left atrial mass, which was suggestive for a atrial myxoma.On the surgery, a tumoral tissue in the left atrium and pulmonary veins with attachment to peripheral sof...
