title: Hobnail haemangioma associated with the menstrual cycle.
abstract: We report the third case in the literature of a hobnail haemangioma with cyclic changes throughout the menstrual cycle in a 36-year-old woman, suggesting a hormonal basis for the variations in the tumour. This patient was under oral contraceptive treatment due to ovarian endometriosis, making the clinical diagnosis difficult.
