Sobani, M. Sohail Awan* Department of Otorhinolaryngology, Head & Neck Surgery, Aga Khan University Hospital, Karachi, Pakistan Abstract Rhabdomyosarcomas (RMS) are thought to arise from pluripotent muscle cell precursors intended to form the body’s future striated muscle. Due to the wide distribution of striated muscle across the body these tumors may appear anywhere and cause symptoms accordingly. Presenting symptoms are highly variable and based on the tumor size and location making clinical diagnosis difficult. The diagnosis of RMS is based on histological examination; however they express varying cytologic pictures representing the different stages of rhabdomyoblasts and their development into skeletal muscle presenting pictures from highly to poorly differentiated neoplasms. Therefore their histological diagnosis also requires the use of specialized stains and complex staining procedures which may not be available at peripheral centers. Here we would like to present a highly aggressive embryonal rhabdomyosarcoma of the maxilla, presenting as a schwanoma on initial histopathology. Keywords Rhabdomyosarcoma; Embryonal; Schwanoma
