Posthysterectomy pelvic leiomyomas with pseudo-Meigs syndrome and metastasis to gluteal soft tissue

Benign metastasising leiomyoma (BML) is a rare condition marked by well-differentiated smooth muscle tumours appearing outside the uterus in women with a history of uterine leiomyoma. Metastasis from leiomyoma is found to be most common in the lungs (79.5%), but other organs, including the heart, lymph nodes, spine and soft tissues, can also be affected. 1 2 Fitzhugh et al reported that deep soft tissue metastasis of benign leiomyoma is very rare, with only 60 cases documented in the English literature up to that point.3 We describe a similar case of posthysterectomy pelvic leiomyoma with gluteal soft tissue metastasis.
