Abstract

Leiomyomatosis peritonealis disseminata (also known as disseminated peritoneal leiomyomas) is a rare disorder consisting of multiple soft tissue masses dispersed throughout the abdominal and pelvic peritoneum, histologically characterized by benign smooth muscle bundles without atypia or mitotic activity. Although more commonly confined to the uterine parenchyma (i.e. uterine fibroids), extension to surrounding structures may rarely occur. Such benign masses may be easily mistaken for more aggressive and malignant etiologies, and if mistaken, may cause psychological stress, time-consuming workup, and unnecessary cost to the patient. Given this possibility, it is important to consider this differential diagnosis among more worrisome pathologies such as lymphoma, metastatic ovarian cancer, or peritoneal carcinomatosis. We present the case of an adult female who initially presented with sharp epigastric abdominal pain, in which subsequent workup revealed the presence of multiple soft tissue lesions scattered throughout the abdomen and pelvis. These lesions were initially misconstrued to be malignant, however, subsequently biopsy-proven to be leiomyomatous tissue in origin.
