Syringoma are benign eccrine sweat duct tumors, typically found clustered on eyelids.  They are skin-colored or yellowish firm, rounded bumps, 1–3 mm in diameter, and may be confused with xanthoma, milia, hidrocystoma, trichoepithelioma, and xanthelasma. They are more common in women and are most commonly found in middle-aged Asian women. They are usually not associated with any other symptoms.

#Pinhole technique (Erbium or CO2 laser)
  • Syringoma highlighted by white circles; This type of lesion most often occurs in women in their 40s and 50s. Laser treatment (pinhole method) can be effective in improving the appearance of the lesion.

    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.
     Syringoma: A Clinicopathologic and Immunohistologic Study and Results of Treatment 17326243 
    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).
