Leiomyomas are benign mesenchymal tumors which originate from smooth muscle cells. Extrauterine leiomyomas are rare and they may arise where smooth muscle cells are found. Their diagnosis is challenging due to their heterogeneous ways of presentation. Histological analysis may reveal areas of sarcomatous differentiation; therefore, complete resection of the entire tumor is the only curative treatment. There is no adjuvant therapy proved to increase overall survival. It is essential to develop a standardized protocol, detailing how to follow up these patients since it is not reported in the literature to date; however, it is advisable to follow them because the local recurrence rate is high if small implants remain. In this review, we present 3 cases of extrauterine leiomyomas diagnosed and treated in our hospital. The management was different in each case, highlighting the heterogeneity of this condition. According to the literature, there are no solid guidelines on their management. We compare our experience with the data available to date in order to support the existing knowledge and provide our expertise for future studies.
