Rare Endobronchial metastasis from uterine leiomyosarcoma.

Abstract

Uterine sarcomas are rare and represent approximately 3.2% of all invasive uterine cancers. The annual incidence rate is less than two per 100,000 women. The median age at which uterine sarcoma diagnosed is 56 years. The most common histologic pattern is leiomyosarcoma (LMS) which originates from the myometrium or myometrial vessels. Uterine LMSs are aggressive tumors with high rates of recurrence. The most common mode of spread is hematogenous, with lymphatic spread being rare. Recurrences of up to 70% are reported in stage I and II disease with the site of recurrence being distal, most commonly the lungs or the upper abdomen. But the intra bronchial spread is extremely rare. Here we are reporting a case of uterine LMS with endobronchial metastasis causing whole lung collapse.
