Large Basal Cell Carcinoma

A gradually enlarging nodule on the pre-auricular facial skin developed in a 68-year-old man who was otherwise in good health. The lesion was asymptomatic. There was no regional adenopathy.

Key point: The lesion’s location, along with visible telangiectasia on the lesion’s surface, suggest a basal cell carcinoma. Biopsy verified this tentative diagnosis.

Treatment: Because of the lesion’s size (2 cm x 2 cm) and location (near branches of the facial nerve), Moh’s surgery with microscopic control was performed, rather than deep excision.  

Note: While basal cell carcinoma only rarely metastasizes, it can cause important anatomical disruption in select areas and may require very careful removal.
