[Primary melanoma of female urethra: A case diagnosed in Ouagadougou]. / Mélanome primitif de l'urètre féminin : à propos d'un cas diagnostiqué à Ouagadougou.

ABSTRACT

We report a case of primary melanoma of a female urethra diagnosed at a non-metastatic stage in a 48-year-old patient with a history of breast carcinoma treated with radiotherapy and hormone therapy. The patient was consulting for dysuria, hematuria, and perineal pain. The clinical examination found a prolapsed and black mass, developed at the expense of the urethra and located at the anterosuperior part of the vulva. The mass biopsy revealed a proliferation of fusiform and globular cells loaded with black pigment expressing the anti-HMB 45 and PS 100 antibodies. The extension assessment showed an absence of secondary localization. The patient underwent total cystourethrectomy without inguinal lymphadenectomy. There was no recurrence observed on day 100 following the surgery.
