Inguinal Scar Endometriosis: A Rare Combination of Two Conditions

Endometriosis has been observed throughout history, well before modern medicine developed taxonomy and treatment for this frequently seen benign condition. Endometriosis was discovered microscopically and described in the 19th century by Von Recklinghausen. These lesions commonly occur in females of childbearing age and can be found invading any organ in the human body. They present with cyclical pain that waxes and wanes with the menstrual cycle, dyspareunia, dysmenorrhea, and other symptoms that drastically lowers quality of life. Endometriosis may take many years to produce noticeable symptoms. A serious cause of concern is when these lesions remain unnoticed and undergo malignant transformation into clear cell carcinoma or endometrioid carcinoma. The prognosis for these malignancies is usually poor, which further stresses the importance of screening and early surgical intervention. We recommend that our patients be attentively heard and carefully examined during routine checkups, especially if they present with known or uncommon gynecological symptoms. There are many presentations of this disease with many theories to explain the pathophysiology, however, our case will focus on iatrogenic influence during abdominopelvic procedures. Our patient’s case involves a rare case of “Inguinal-Scar Endometriosis” associated with progressively increasing burning pain along a surgical scar accompanied with a palpable subcutaneous mass.
