Omnipresent, omnipotent - extra-uterine leiomyosarcoma with varied presentation - case series of a dozen!!

Background: Leiomyosarcoma (LMS), accounting for 7-10% of all soft tissue tumors, is derived from smooth muscles and arises most commonly from uterus, retroperitoneum, extremities, but can potentially involve any site of the body. Through this case series of 12 extra-uterine LMSs, we highlight the wide variety of clinical presentations of this tumor. Methods: Retrospective analysis of clinical details, histopathological examination (HPE) and immunohistochemistry (IHC) of LMSs diagnosed in the extra uterine sites from 2012-2016 in our tertiary care institute. Result: The mean age of presentation was 55.8 years, with male: female ratio 2:1. The site distribution was: stomach (3), non visceral soft tissue-thigh (2), breast (2), cutaneous (2), ileum(1), esophagus(1), and larynx (1). Conclusion: The variable presentations of LMS at extra-uterine sites, makes it a challenging diagnosis for the unsuspecting clinicians and histopathologists. Thus, any soft tissue tumor in similar clinical scenarios may turn out to be LMS. DOI:10.21276/APALM.1588
