Eyelid desmoplastic trichilemmoma: 2 case reports and review

Desmoplastic trichilemmomas (DTs) are a rare variant of trichilemmomas first described in 1985. Since then, 11 cases involving the eyelid have been reported. Two cases of this study raise this total to 13. DTs are often clinically confused with basal cell carcinoma and must be proven by biopsy to obtain the correct diagnosis. These lesions are more commonly present in patients older than 50 years. Despite the fact that they are benign, they are often associated with basal cell carcinomas and as such should be managed carefully, requiring excisional biopsy with frozen borders or Mohs controlled margins.
