Inguinal Endometriosis: An Uncommon Differential Diagnosis as an Inguinal Tumour

Inguinal endometriosis can present as a rare tumor when it occurs outside the abdomen and pelvis. We present a patient with a painful tumor in the right inguinal region, where its diagnosis was made before the operation. This enabled a conservative excisional surgery to be performed. The literature is reviewed and the diagnosis as well as management are discussed.
