Incidental Syringomas of the Scalp in a Patient with Scarring Alopecia

Abstract

Syringomas are benign adnexal neoplasms of eccrine lineage, which occur most commonly in the periorbital region in middle-aged females. These cutaneous lesions rarely occur on the scalp, are typically asymptomatic and are predominantly of cosmetic significance. Involvement of the scalp may be indistinguishable from that of scarring alopecia. We present an unusual case of clinically inapparent syringomas occurring on the scalp of a 56-year-old female with alopecia who was subsequently diagnosed with lichen planopilaris after repeated scalp biopsy. In patients with unexplained hair loss, or in cases that are refractive to treatment, clinicians should perform scalp biopsy to exclude the diagnosis of rare neoplastic lesions like syringomas and to diagnose associated conditions.

Keywords: Alopecia; Lichen planopilaris; Scalp; Syringoma.
