Syringomas are benign eccrine sweat duct tumors, typically found clustered on eyelids, although they may also be found in the armpits, abdomen, chest, neck, scalp, or groin area, including genitals, in a symmetric pattern. 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. While they can present at any time in life, they typically present during adolescence. They are usually not associated

Syringomas are benign eccrine sweat duct tumors, typically found clustered on eyelids, although they may also be found in the armpits, abdomen, chest, neck, scalp, or groin area, including genitals, in a symmetric pattern. 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. While they can present at any time in life, they typically present during adolescence. They are usually not associated with any other symptoms, although can sometimes cause itchiness or irritation.
== Types== The eruptive form typically presents on the anterior chest, abdomen, neck, and arms. It presents in successive crops with periods of relief in between times of active rash. The milia-like type of syringoma is typically smaller lesions that have a milky white center that can look like milia. The plaque type is more commonly associated with itchiness and chronic scratching that leads to epidermal thickening similar to lichen planus. The familial form, in some cases of syringoma, exhibits a familial pattern in an autosomal-dominant pattern of inheritance. Chromosome 16q22 has been shown to be involved in the genetic links of syringoma.
