Undifferentiated pleomorphic sarcoma (UPS) or Malignant fibrous histiocy- toma (MFH)
Abstract Malignant fibrous histiocytoma (MFH), currently classified as undifferentiated pleomorphic sarcoma, is the most frequent soft tissue sarcoma in adulthood, but it is not as common as a primary skin tumour. We report a case of 50-year-old male cultivator with no significant previous medical history who presented with a solitary painless ulcerated tumour on the right knee. Histopathological findings of ulcer showed pleomorphic cells in the dermis, areas of necrosis and mitotic figures and histopathology of lymph nodes showed tumour metastasis. Probably we are reporting this type of case for the first time in Bangladesh. Keywords: Undifferentiated pleomorphic sarcoma; Malignant fibrous histiocytoma |
