Introduction: Endometriosis is a disease characterized by the presence of endometrial glands and/or stroma outside the uterine cavity. The main location is the ovary, but it has been described in many other extragenital locations, mainly the intestinal wall and the epiplon, but also the lung and the skin.
Materials and methods: In this report we review the cases of cutaneous endometriosis diagnosed at Fundación Jiménez Díaz in Madrid in the last decade.
Results: In this time period we have seen 376 specimens with endometriosis, 330 from ovarian origin, 11 cases involving the appendix, 3 affecting the uterine cervix, 3 involving the epiplon, 1 in an ileal lymph node, 5 in the small intestine, 6 in the large intestine, 2 affecting the lung (with recurring pneumothorax) and 15 involving the skin.
Conclusion: We comment on the features of the patients with cutaneous endometriosis and their gynaecological history.
