Syringoma - 汗管瘤https://en.wikipedia.org/wiki/Syringoma
汗管瘤 (Syringoma) 是良性小汗腺導管腫瘤,常聚集於眼瞼。它們呈膚色或淡黃色,質地堅硬,呈圓形腫塊,直徑1–3 毫米,可能與黃色瘤、粟丘疹、汗囊瘤、毛髮上皮瘤和黃斑瘤相混淆。此病在女性中較常見,最常見於中年亞洲女性。通常不伴隨其他症狀。

    34 名患者分為兩組(localized and generalized syringoma)。患者以女性為主,佔 97%,平均年齡 28 歲。於尋求治療前,病變平均已存在六年。Generalized syringoma 主要影響胸部和頸部,其次是前臂;而 localized syringoma 主要見於臉部、腋窩和生殖器區域。
    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.

    我們的研究旨在描述韓國皮膚科診所於四年內診斷為汗管瘤的 61 名患者的臨床與組織病理學特徵。結果顯示,汗管瘤主要影響女性,女性與男性的比例為 6.6 比 1,且多半發生於患者的第二、第三個十年。最常見的受累部位為眼瞼(71%),病灶大多呈膚色(49%)。在 56% 的病例中觀察到特徵性的蝌蚪狀外觀。基底色素沉著過度較常見於棕色病變,而纖維化則較常見於紅斑病變。此外,涉及生殖器區域的病例中,角蛋白囊腫較少見。
    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).
