Features:

• Dermal lesion with nests of cells that are surrounded by hyaline, i.e. glassy eosinophilic acellular, material and have:
  • Hyperchromatic nuclei that may palisade; columnar nuclei arranged around the periphery of the cells nests - with their short axis tangential to the nest periphery, and
  • Cells with lighter staining ovoid nuclei at their centre.
  • Lack of a significant number of lymphocytes - differentiates from spiradenomas.

This neoplasm should not be confused with a cylindroma arising from the salivary gland, also known as an adenoid cystic carcinoma.
