Primary alveolar rhabdomyosarcoma of fallopian tube masquerading as a unilateral adnexal mass: A case report and literature review.

ABSTRACT

Rhabdomyosarcoma (RMS) is a high‑grade sarcoma that predominantly affects children, and rarely, the adult population. RMS demonstrates three major histologic variants Embryonal, alveolar, and pleomorphic. A limited number of documented pure RMS cases of the gynecologic organs in adult women are found in the literature. Of these reports, the fallopian tube (FT) is reported as the primary site in only three cases, those included one of embryonal and two of the pleomorphic histologic variants. Herein, we report the first case of alveolar RMS arising in the FT of an adult woman and presenting as a unilateral adnexal mass.
