![]() | Media file 1: Characteristic clinical morphologic features. Notice the numerous, small papules, predominantly close to the midline. |
![]() | Media file 2: Well-circumscribed, superficial lesion composed of clusters of basaloid cells within a fibrous stroma. This arrangement of epithelial cells and stroma is described as organoid. |
![]() | Media file 3: The cystic spaces contain keratin. Notice the lack of mitotic figures or apoptotic bodies. |
![]() | Media file 5: Immunohistochemical studies detect expression of CD34 by many of the dendritic cells that surround the tumor aggregates (anti-CD34, diaminobenzidine, and hematoxylin). |
![]() | Media file 7: High-powered view of desmoplastic trichoepithelioma. Notice the cluster of squamous cells surrounding a small cystic area containing keratin. Intervening stroma is markedly fibrous. |
