Abstract

Rhabdomyosarcomas (RMSs) are malignant soft-tissue tumors arising from skeletal muscle progenitor cells. They are most commonly diagnosed in children and adolescents and are rare in adults. These tumors arise from a variety of anatomical sites, including the head and neck, urogenital tract, and extremities. Classification of RMSs depends on histopathologic and immunohistochemical features. Embryonal and alveolar subtypes are more common in children and adolescents, whereas the pleomorphic subtype is seen almost exclusively in adults. Adult RMS is associated with poor outcomes and high recurrence rate. Because of the low incidence of adult RMS, most published reports of RMS in adults are either case series or retrospective analyses, and most treatment protocols are extrapolated from clinical trials performed in children. The present report describes a 61-year-old woman with RMS whose presentation included atypical symptoms.
