Overview
To diagnose basal cell carcinomas, a biopsy (where tissue is taken for pathological study) is done using local anesthesia. In small lesions, the tumor is generally removed in its entiriety, while larger ones are biopsied first and surgically removed later if it is confirmed that it is malignant.
Histopathology
Basal cell carcinoma is a malignant epithelial tumor arising only in skin, from the basal layer of the epidermis or of the pilosebaceous adnexa. Tumor is represented by compact areas, well delineated and invading the dermis, apparent with no connection with the epidermis. Tumor cells resemble normal basal cells (small, monomorphous) are disposed in palisade at the periphery of the tumor nests, but are spindle-shaped and irregular in the middle. Tumor clusters are separated by a reduced stroma with inflammatory infiltrate. 1
-
This elderly patient was noticed to have a basal cell carcinoma of the concha, just behind the tragus.
-
The tumor was removed and the defect closed with a full thickness skin graft (FTSG) from the neck.
-
This photograph was taken three weeks later. The full thickness skin graft has taken well.
