Leiomyoma and Leiomyosarcoma Arising from the Round Ligament of the Uterus

Abstract

A 43-year-old woman presented with an asymptomatic, enlarging right groin mass she had first noticed 6 months earlier. On examination, she had a soft, mobile, nontender mass in the right inguinal region. MRI demonstrated a heterogeneous 9-cm SC tumor (A), and CT-guided biopsy showed leiomyoma. At operation, a well-encapsulated tumor was found originating from the right round ligament of the uterus and this mass was completely resected. Microscopic analysis revealed elongated cells, cigar-shaped nuclei, and low mitotic activity, consistent with benign cellular leiomyoma (B). B View Large Image Figure Viewer Download Hi-res image
