Histology

Intraepidermal tumor consisting of (usually) multiple islands of tumorous cells, which are surrounded by hyaline sheath and fit together like pieces of a jigsaw puzzle. The hyaline sheaths and hyaline droplets within the tumor are PAS positive.

The tumor consists of two kinds of cells: smaller, on the periphery of the nests (with narrower cytoplasm), and larger, more centrally located, with pale nucleus and eosinophilic cytoplasm.

The tumor can contain tiny tubules.
