Dermal cylindroma Classification and external resources 
Micrograph of a dermal cylindroma. H&E stain.ICD-O: M8200/3 eMedicine derm/94 MeSH D003528 In dermatologic pathology, a dermal cylindroma, also dermal eccrine cylindroma[1]:666) and (less specifically) cylindroma, is a benign adnexal tumor,[2] which occurs on the scalp and forehead.
Multiple cylindromas may grow together in a "hat-like" configuration, the so-called "turban tumor." Cylindromas are uncommon dysplasias of skin appendages.[3]

Histology
Dermal cylindromas are:
- dermal lesions consisting of 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.
They lack of a significant number of lymphocytes; this differentiates them from spiradenomas.
