Endometriosis is typically known as a condition affecting people with a uterus, predominantly women of reproductive age. However, recent medical reports have documented extremely rare cases of endometriosis in men. While very uncommon, with fewer than 20 cases reported worldwide, these instances provide important insights into the disease's complexity and the necessity for awareness beyond traditional perceptions. In male patients, endometriosis tissue has been found in locations such as the lower genitourinary tract, bladder, lower abdominal wall, and inguinal region. Symptoms can vary depending on the location of the endometrial tissue but often include lower abdominal pain, pelvic stabbing pain, scrotal swelling, testicular pain, and even hematuria (blood in urine). These symptoms resemble those experienced by women but may be overlooked in men due to the rarity of the condition. Diagnosis of endometriosis in men is challenging because initial imaging tests like ultrasounds or MRI may only suggest the presence of a mass. Definitive diagnosis usually requires surgical excision and histological analysis, which can reveal endometrial-like tissue in the affected area. Key diagnostic markers, such as CD10 protein positivity, support the identification of endometrial tissue despite the absence of typical female hormone receptors. Understanding that endometriosis can rarely occur in men helps challenge the misconception that it is solely a female disease and underscores the importance of careful evaluation of symptoms related to pelvic and abdominal pain, regardless of gender. Awareness by both healthcare providers and patients is essential for timely diagnosis and appropriate treatment. Although surgical removal of endometrial lesions remains the main approach, ongoing research aims to better understand the mechanisms and improve management strategies for all affected individuals. If you or someone you know experiences unexplained pelvic or testicular pain, consulting a healthcare professional is crucial to rule out rare but significant conditions such as endometriosis. Increased awareness and knowledge can empower patients and improve outcomes in these rare male cases.
