Two cases of trichilemmal carcinoma (TLC) developing in burn scars are reported. In Case 1, a 73-year-old man developed a TLC on his left lower leg five years after a burn. In Case 2, a 43-year-old man developed a cauliflower-like mass on his head 42 years after a burn. ⋯ Tumor nests were mostly composed of large atypical cells with clear cytoplasms containing PAS-positive, diastase sensitive materials. Some of the nests showed trichilemmal-type keratinization. These cases were treated only with surgical excision, and there has been no evidence since of local recurrence or metastasis.
