Aggressive angiomyxoma as an incidental finding in a man during a routine check-up

Deep (aggressive) angiomyxoma is a rare benign mesenchymal tumor that usually arises from the soft tissues of the perineum and pelvis in premenopausal women. As of September 2020, only 88 cases of aggressive angiomyxoma in men have been reported. Deep or aggressive angiomyxoma is usually asymptomatic. At the same time, it is characterized by slow growth, a tendency to deeply invade the tissues of the retroperitoneal space and the muscles of the pelvic diaphragm. The article discusses a clinical case of deep angiomyxoma detection in a man during a medical examination. The importance of conducting a thorough differential diagnosis, regular preventive examinations and medical examinations by patients, as well as the significance of an objective physical examination of the patient at each visit to the doctor for the earliest possible detection of signs of neoplasms is shown.
