A Case Report with Literature Review: Parasitic Leiomyoma

Abstract

Leiomyoma is a benign tumour composed mainly of smooth muscle cells. It contains varying amount of fibrous connective tissue s . Parasitic leiomyoma is a rare manifestation of uterine leiomyoma defined as a pedunculated subserosal fibroid that undergoes torsion and detaches from the uterus. We are reporting a case of parasitic leiomyoma in a 55 Y/O female patient that had already given her consent for the case to be published. She presented with increased abdominal girth since 6 months and body weight and consulting for possible bariatric surgery 1 month prior to presentation. Ultrasonography revealed a large heterogeneous mass starting from the pelvic region to the middle and upper abdomen of more than 37 cm compatible with an adnexal mass. On abdominopelvic MRI: presence of an enlarged heterogeneous mass that seems taking its origin from the right ovary , an exploratory laparotomy was performed. Identification and complete excision of a huge mass of cystic and solid component adherent to the uterus and the mesentery of the small bowel. Histopathologically mass was confirmed as a hyelanized leiomyoma with a focal necrobiosis with no signs of malignity. Parasitic leiomyomas are rare tumors. Imaging modalities help in diagnosis but not always. The definitive treatment is surgical excision , presenting this case due to its rarity and diagnostic difficulties posed.
