[Collision tumor].
A 65-year-old woman presented with a painless, partially pigmented and partially hyperkeratotic tumorous lesion on the lower eye lid. Histopathologic findings of the wedge resection showed a collision tumor of a highly differentiated squamous cell carcinoma and a fibrosing basal cell carcinoma. Collision tumors involving these two components are rare, particularly in the periocular region.
