| Abstract: | 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. |
