title: Trichilemmal carcinoma: a rare cutaneous malignancy: a report of two cases.
abstract: BACKGROUND
  Trichilemmal carcinoma is a rare cutaneous malignancy that usually occurs on the sun-exposed areas of older individuals. The lesion is usually solitary and may present as an exophytic or polypoid nodule that maybe hyperkeratotic with ulceration.
  
  
  OBJECTIVE
  To present two cases of trichilemmal carcinoma, one occurring in a kidney transplantation patient.
  
  
  METHODS
  Two case reports and a discussion of the rare carcinoma are presented.
  
  
  RESULTS
  Both lesions were treated with Mohs micrographic surgery without sign of recurrence after several years.
  
  
  CONCLUSIONS
  Trichilemmal carcinoma is a rare cutaneous malignancy that can be seen in both immunocompetent and immunosuppressed hosts. Mohs micrographic surgery should be considered among the surgical options to avoid a wide surgical excision in these patients.
