Basaloid Squamous Cell Carcinoma of the Uterine Cervix in a Northern Nigerian Hospital: A Case Report and Review of Literature

Basaloid squamous cell carcinoma occurs very rarely in the uterine cervix. Basaloid squamous cell carcinoma is a form of squamous cell carcinoma with a poor prognosis that primarily affects persons in their late sixties and early seventies. This paper describes a case of Basaloid squamous cell carcinoma in the fifth decade that had spread to the myometrium, ovaries, and fallopian tubes. The macroscopic findings of a total abdominal hysterectomy and bilateral salphingo-oophorectomy revealed an ulcerative fungating tumor distorting the whole cervix and macroscopic invasion of the posterior uterine wall. Histologic features revealed a Basaloid tumour disposed in nest exhibiting peripheral palisading and stromal retraction with most of the nest having comedo pattern of necrosis. The tumour cells are fairly small uniform round cells, with scanty cytoplasm having increased nuclei cytoplasmic ratio with vesicular to open nuclei. Immunohistochemical stains; Cytokeratins, EMA, p63 and Ki-67 showed cytokeratin positivity and EMA strong and diffuse positivity.
