Alopecia Associated with Occult Syringoma
|
|
|

Abstract
|
|
|
Occult syringoma means a clinically inapparent tumor of the sweat gland that are histologically similar but not identical with the common syringoma. They may occur in a variety of inflammatory skin lesions and cutaneous neoplasms as a reactive
process.
We report herein a case of diffuse alopecia areata associated with occult syringoma in the scalp of a 57-year-old man. Our patient developed progressive, fairly well circumscribed patches of alopecia and diffuse hair loss over a 1 month period.
Histopathological examination revealed non-scaring alopecia and a proliferation of eccrine ductal structures in the upper dermis. These ductal structures resembled syringoma. Only minimal focal fibrosis was occasionally observed around the hair
follicles.
We believe that occult syringona is a reactive process and is secondary to active inflammation or dermal fibrosis. It has been most commonly observed in scarring alopecias but plays no significant role in the etiology of hari loss. (Kor J
