Cutaneous ciliated cyst
DefinitionThis section has been translated automatically.
Rare, asymptomatic, skin-colored lump typically found on the lower legs in young women.
EtiopathogenesisThis section has been translated automatically.
The origin is unknown. Discussed are atypically localized or scattered remnants of the Müller duct (embryonic sexual duct, which develops at the beginning of the 2nd embryonic month from a depression of the celomepihtel and develops into fimbriae and tubes in the female sex). Epithelial cysts from scattered Müller ducts develop mainly in uterus and vagina, more rarely extragenital.
ManifestationThis section has been translated automatically.
Almost exclusively among women; very occasionally, publications on appearance among men.
LocalizationThis section has been translated automatically.
Typically on the lower legs.
Clinical featuresThis section has been translated automatically.
1-3 cm in diameter large, dermal, symptomless, cystic nodule. In case of a rupture emptying of a mostly clear secretion. The diagnosis is usually made as a random histological finding.
HistologyThis section has been translated automatically.
Dermal unilocular or chambered cyst whose wall is covered by a multi-row prismatic ciliated epithelium. Frequent formation of "papillary projections" into the glandular lumen.
TherapyThis section has been translated automatically.
Excision is curative.
Note(s)This section has been translated automatically.
There is probably a close etiological relationship to the ciliated cyst of the vulva. It seems reasonable to summarize both under the term "Müller cysts" with addition of the localization.
