Solid Variant of Adenoid Cystic Carcinoma Coexisting with Invasive Squamous Cell Carcinoma in Uterine Cervix – A Case Report with Immunoprofile

Abstract

Primary adenoid cystic carcinoma of cervix is a rare entity. Co-existence of adenoid cystic carcinoma with squamous cell carcinoma is even more rare. Here we present the case of an 85 year old postmenopausal lady who presented with on and off vaginal bleeding and was found to have a hard cervical mass. Hysterectomy with bilateral salpingo-oophorectomy was done and histopathological evaluation revealed coexisting solid variant of adenoid cystic carcinoma and squamous cell carcinoma. High grade squamous intraepithelial lesion was seen adjacent to invasive squamous cell carcinoma. Adenoid cystic carcinoma was positive for CD117 and squamous cell carcinoma was positive for p63. Both the components were also immunoreactive for p16.
