Epithelioid rhabdomyosarcoma: A rare case report mimicking carcinoma breast

Rhabdomyosarcoma (RMS) is an unusual sarcoma in adults. There are four main types of RMS described in the literature, including embryonal, alveolar, pleomorphic, and spindle cell type. Epithelioid RMS is a relatively newer form of RMS described in the literature, with little information regarding the natural course and management. We present a rare case of a young woman with metastatic epithelioid RMS, with an atypical presentation with bilateral large breast lumps, large ovarian mass progressing rapidly to metastasize, involving multiple sites. It has an aggressive clinical course with poor response to therapy.
