Embryonal rhabdomyosarcoma of the uterine corpus mistaken for small cell carcinoma: a case report.

: Pure rhabdomyosarcomas of the female genital tract mostly occur in infancy and childhood, in the form of sarcoma botryoides (a variant of embryonal rhabdomyosarcoma), with vagina and cervix as typically involved sites. Such tumors rarely occur in the uterine corpus and cervix of adults. We would like to report a pure embryonal rhab-domyosarcoma of the uterine corpus that arose in a 31-year-old, gravida 1, para 1, female patient with widespread bony metastasis, and which was originally mistaken for metastatic small cell carcinoma to bone marrow.
