Abstract
Lipoleiomyoma is an uncommon neoplasm of the uterus with a variable incidence in the literature. Histologically, it consists of smooth muscle cells intermixed with mature adipocytes. The histogenesis of this tumor remains obscure and the presence of atypical cells may raise the suspicion of leiomyosarcoma so it is crucial to distinguish between the two. On the other hand, tumor-associated mast cells are being recognized as tumor modulators and potential therapeutic targets. Here, we discuss the case of a 57-year-old female, who presented with a nonspecific symptom of postmenopausal bleeding. She was found to have a large uterine mass and had been treated surgically with a hysterectomy. Histological examination revealed the diagnosis of this uncommon entity. Considering the rarity of the disease, we report this case to add to the existing literature. Furthermore, the significance of these findings is still poorly understood and needs more investigation to fill in the lacking knowledge.
