	#~~redirect~~ [[Dermatologic neoplasms~~#Dermal_cylindroma~~]]		'''Dermal cylindroma''' is a benign skin lesion classically seen on the scalp.

			It should '''not''' be confused with ''cylindroma'' ([[adenoid cystic carcinoma]]).

			==General==
			*Benign skin lesion.
			**Occasionally malignant.<ref name=pmid16882695/>
			*May be related to ''[[eccrine spiradenoma]]''.<ref name=pmid6302142>{{Cite journal \| last1 = Gerber \| first1 = JE. \| last2 = Descalzi \| first2 = ME. \| title = Eccrine spiradenoma and dermal cylindroma. \| journal = J Cutan Pathol \| volume = 10 \| issue = 1 \| pages = 73-8 \| month = Feb \| year = 1983 \| doi = \| PMID = 6302142 }}</ref><ref name=pmid8936072>{{Cite journal \| last1 = Lee \| first1 = MW. \| last2 = Kelly \| first2 = JW. \| title = Dermal cylindroma and eccrine spiradenoma. \| journal = Australas J Dermatol \| volume = 37 \| issue = 1 \| pages = 48-9 \| month = Feb \| year = 1996 \| doi = \| PMID = 8936072 }}</ref>

			May be familial:<ref name=pmid16882695/>
			*Familial cylindromatosis (autosomal dominant).
			*Brook–Spiegler syndrome.

			==Gross==
			*Classically scalp - usually head and neck or face.

			==Microscopic==
			Features:<ref name=pmid16882695/>
			*Nests of cells that fit together like a jigsaw puzzle - the borders of the nests are opposed and undulate.
			*#Basaloid cells with scant cytoplasm and dark nuclei palisade around the edge of the nests.
			*#Larger cells with moderate eosinophilic cytoplasm and lighter staining nuclei are at the centre of the nests.
			*Cells nests surrounded by a band of hyaline (i.e. glassy, eosinophilic, acellular) material ~ 2X thickness of a basilar cell - '''key feature'''.
			**This is basement membrane.

			DDx:
			*[[Eccrine spiradenoma]].
			*[[Basal cell carcinoma]] - has [[myxoid stroma]].
