A Case of Aggressive Basal Cell Carcinoma with Invasion of the Parotid Gland, Temporal Bone and Facial Nerve / 대한이비인후과학회지

ABSTRACT

Basal cell carcinoma (BCC) is the most common dermatologic cancer characterized by slow growing, less invasive and highly curable clinical course. But occasionally, BCC behaves aggressively with deep invasion and potential regional and distant metastasis. Several risk factors, including tumor size, duration, histologic type, and perineural invasion have been postulated as markers of the aggressive BCC phenotype. Tumors occuring along the nasolabial fold or the retroauricular area may be aggressive but that is still debated. Aggressive cases of BCC involving the parotid gland, the emporal bone and the facial nerve have been rarely reported. We report a case of aggressive basal cell carcinoma involving the parotid gland, the temporal bone, and the facial nerve with a review of the literature.
