This paper reports an umbilical nodule caused by endometriosis, described as a diagnostic and clinical presentation at the skin/umbilical site. The authors present the case in the context of endometriosis manifesting outside the pelvis, with the key finding being that the umbilical nodule was due to endometriosis. A major limitation is that, as a brief case report with no abstract provided, it offers limited generalizability beyond the individual presentation. This paper is centrally about endometriosis — it specifically describes an umbilical nodule attributable to endometriosis.

Abstract

Sir, Endometriosis is common, and extrapelvic deposits may occur in up to 12% of affected women. Cutaneous endometriosis is rare, usually appearing in surgical scars or following procedures such as hysterectomy, caesarean sections, episiotomy and laparoscopy. It is probably the result of implantation of viable endometrial cells or their transport via vascular channels. Umbilical endometriosis is rare, with an estimated incidence of 0.5–1% of all patients with endometrial ectopia (1). It can occur after surgery but is generally spontaneous. There is an important differential diagnosis, which includes malignant melanoma, and a metastatic deposit from a systemic malignancy, in particular a gastrointestinal primary tumour, should be considered. We report here a case of umbilical endometriosis in a young woman whose past medical history was unremarkable and highlight how important an accurate history can be in determining correct diagnosis.
