Syringomas Treated by Intralesional Insulated Needles without Epidermal Damage

ABSTRACT

Syringoma is a benign adnexal tumor derived from intradermal eccrine ducts; it predominantly occurs in women at puberty or later in life. Although syringoma is a common benign neoplasm, there have been no effective therapies for its removal. Conventional therapies for syringomas, including surgical excision, electrodessication, chemical peeling, topical atropine or tretinoin, cryosurgery, and laser therapy, can lead to cosmetic defects such as hyperpigmentation or scarring due to epidermal damage. In contrast, treatment using intralesional insulated needles, which are insulated at the point of epidermal contact, has been shown to result in good cosmetic outcomes due to selective destruction of dermal lesions. This could be an effective and highly satisfying treatment for syringomas. We herein present 2 patients with syringomas treated with intralesional insulated needles.
