  • multiple, linearly arranged forms exist
  • age: usualy young adults

Histology

Intradermal tumorouus nodules, sharp circumscription, in scanning magnification may resemble lymphnodes. Bands of tumorous cells with small, dark nuclei on the periphery and larger, pale nuclei in the centre. No hyaline sheats around the bands are present. In addition tubules, PAS positive hyaline granules and scattered lymphocytes are present.

Sometimes this tumor is mixed with cylindroma. In some tumors the cells form small rosettes.

Eccrine and apocrine variants exist.
