Endometriosis is a common gynaecological condition that sometimes presents to general surgeons as a lump in the abdomen. It can pose a diagnostic dilemma and should be in the differential diagnosis of lumps in the abdomen in females. Diagnosis is usually made on histology. We discuss a case of recurrent abdominal wall endometriosis following caesarian section. The incidence, pathophysiology, course, diagnosis, treatment and prevention of this condition are also reviewed.
