CASE HISTORY/EXAMINATION
A 31-year-old woman with history of sudden onset, dull and intermittent
type right-sided flank pain presented to emergency. She did not give
history of hematuria, burning micturition, urinary frequency, urgency,
or fever. She was diagnosed to have a right renal mass on radiological
examination. She underwent a right radical nephrectomy, the
histopathology of which revealed a sarcomatoid tumor with positive
immunostaining of myoid markers (smooth muscle actin and Desmin) and was
thus diagnosed as a case of renal leiomyosarcoma.
