Syringoma https://en.wikipedia.org/wiki/Syringoma
Syringoma sinn benign eccrine Schweesskanal‑Tumoren, déi typesch op den Aelidden zesummegefaasst ginn. Si sinn Hautfaarweg oder gielzeg fest, ofgerënnt Knollen, 1‑3 mm Duerchmiesser, a kënne mat Xanthoma, Milia, Hidrocystoma, Trichoepithelioma (trichoepithelioma) a Xanthelasma verwiesselt ginn. Si si méi heefeg bei Fraen a si meeschtens an mëttelalterleche asiatesch Fraen fonnt. Si sinn normalerweis net mat all aner Symptomer assoziéiert.

Drësseg‑vier Patienten goufen an zwou Gruppen ënnerdeelt (localized and generalized syringoma). D'Patienten ware meeschtens Fraen, déi 97 % ausmaachen, mat engem Duerchschnëttsalter vun 28 Joer. Virun der Behandlung waren d'Läsionen am Duerchschnëtt sechs Joer präsent. Generalized syringoma huet haaptsächlech d'Brust an den Hals beaflosst, duerno d'Ënneraarm, wärend localized syringoma haaptsächlech op d'Gesiicht, Axillen a Genitalberäich fonnt gouf.
Thirty-four patients were sorted into two groups, localized and generalized syringoma, according to the Friedman and Butler classification. Ninety-seven percent of the patients were females with the mean age of 27.6 years. The mean duration of the lesions before the presentations was six years. Distribution of the generalized syringoma was mainly in the chest and neck followed by the forearms whereas localized syringoma was mostly confined to the face, axilla and genitalia.

Eis Etude zielt d'klinesch an histopathologesch Feature vu séchzeg-eent Patienten ze beschreiwen, diagnostizéiert mat Syringoma iwwer eng véier Joer Period an eiser Dermatologie Klinik a Korea. Mir hunn erausfonnt datt d'Syringoma haaptsächlech Fraen betraff, mat engem Verhältnis vu 6,6 Fraen op 1 männlech, an typesch während der zweeter an drëtter Dekade vum Liewen a méi wéi d'Halschent vun de Patienten erschéngt. Déi heefegst betraff Plaz waren d'Aelidden (71 %), an d'Läsionen (lesions) ware meeschtens Hautfaarweg (49 %). Mir hunn charakteristesch Tadpole-ähnlech Erscheinungen (tad‑pole appearances) an 56 % vun de Fäll observéiert. Basal Hyperpigmentatioun (basal hyperpigmentation) war méi heefeg bei brongfaarwege Läsionen (lesions), während Fibrose (fibrosis) méi heefeg an erythematöse Läsionen (erythematous lesions) war. Zousätzlech waren Keratinzysten (keratin cysts) manner heefeg a Fäll mat dem Genitalberäich.
The purpose of our study was to describe clinical and histopathological features of sixty one patients with histological diagnosis of syringoma over four year period in our dermatology clinic in Korea. Female:male ratio was 6.6:1 with onset of age during 2nd and 3rd decades in more than half of the patients in our study. The most frequently involved site was eyelids (43 cases, 70.5%) and the most common color of lesion was skin-color (30 cases, 49.2%). In 34 cases, characteristic tad-pole appearances (55.7%) were observed. Basal hyperpigmentation was observed more frequently in brown-colored lesion (p=0.005). Fibrosis was observed more frequently in erythematous lesion (p=0.033). Keratin cyst was observed less frequently in genital involved group (p=0.006).
