Basal Cell Adenocarcinoma of Parotid Gland

Abstract

Basal cell adenocarcinoma (BCAC) of salivary gland is a rare tumor, only few reports have been described in the literature so far. These tumors appear benign clinically. Metastasis is reported in less than 10% of cases. BCAC is considered as low-grade carcinomas due to its biological behavior and prognosis. Parotidectomy with preservation of the facial nerve is considered as treatment of choice. Neck dissection has to be performed in cases with cervical metastases. Radiation is advisable in patients with recurrent disease or neck nodal metastasis. Intensive follow-up is necessary because there is 30% recurrence rate. In this case report, we describe a giant basal cell adenocarcinoma in a 50-year-old female patient who was managed with extended parotidectomy along with excision of intralesional facial nerve and involved adherent skin. Reconstruction was done with latissimus dorsi flap and sural nerve cable grafting for facial nerve.
