Umbilical endometriosis and tumours in umbilicus
Umbilical endometriosis is rare, representing only 0.5-1% of all cases of extragenital endometriosis. In infertile women, endometriosis may be as prevalent as 50%. Numerous differential diagnoses are present, hence the clinical diagnosis of umbilical tumours is intricate. In a 33-year-old woman, an umbilical tumour presented 12 months prior to referral. On referral, no cyclic bleeding was noticed, although intermittent bleeding and soreness of the element were present. Dysmenorrhoea, dyspareunia, intermittent pelvic pain, and three years of infertility were noted. A biopsy showed endometriosis.
