Mixed type basal cell carcinoma of the eyelids.
A retrospective histopathologic review of 97 patients with basal cell carcinoma of the eyelid was performed to determine the prevalence and behavior of tumors with a mixed pattern of growth. A mixed type basal cell carcinoma was defined as a tumor having a significant nodular or ulcerative component combined with an infiltrative component. Histologic classification of the 97 tumors yielded four (4.1%) that were multicentric, 67 (69.1%) that were nodular, one (1%) that was ulcerative, 13 (13.4%) that were infiltrative, and 12 (12.4%) that were the mixed variant. Follow-up was obtained on 8 of the 12 patients with mixed basal cell carcinoma. Three tumors recurred, but there were no tumor-related deaths. One of these patients underwent numerous eyelid resections over a 2-year period and then underwent an orbital exenteration. The authors conclude that mixed type basal cell carcinomas are not infrequent and behave as aggressively as basal cell carcinomas of the morphea type. A greater awareness and recognition of mixed type basal cell carcinomas by ophthalmologists and pathologists should result in fewer recurrences and better patient management.
