Basal cell carcinoma occurring in scar tissue following excision of a parotid gland pleomorphic adenoma.
BACKGROUND
A 49-year-old patient presented with a basal cell carcinoma growing on scar tissue left following excision of a parotid gland pleomorphic adenoma.


OBJECTIVE
The objective was to determine whether the basal cell carcinoma had resulted from tumor spillage at the time of the pleomorphic adenoma excision.


METHODS
Substantial evidence is presented linking the two tumors.


RESULTS
The basal cell carcinoma most likely occurred as the result of tumor spillage at the time of the parotid gland pleomorphic adenoma excision.


CONCLUSIONS
Cutaneous connective tissue stroma plays a significant role in determining the differentiation of basal cell carcinomas.
