Eccrine Hidrocystoma in a Child: An Atypical Presentation

“…EH must be differentiated from apocrine hidrocystomas. Apocrine hidrocystoma is usually larger and it does not become more prominent in hot environments or after exercise 10 . Apocrine hidrocystomas affect the same age groups as do EHs, and they rarely occur during childhood or adolescence 2 .…”

Multiple eccrine hidrocystomas of the vulva

“…Multiple-type lesions have been successfully treated with topical 1% atropine or scopolamine creams [3]. Improvement following 585-nm pulsed dye laser treatment was unclear [4]. New treatment modalities may provide better clinical approaches to this uncomfortable condition.…”

A Case Report of Multiple Eccrine Hydrocystomas Successfully Treated with Subdermal 1,444-nm Micropulsed Neodymium-Doped Yttrium Aluminum Garnet Laser

“…EHs tend to enlarge with excessive sweating caused by warm temperature, hot baths, or heavy exercise, probably because of sweat retention. There have been previous reports of EHs treated with laser, namely the long pulsed‐dye and carbon dioxide lasers . A new 1,444‐nm 100‐μs micropulsed subdermal neodymium‐doped yttrium aluminum garnet (Nd:YAG) laser was recently developed .…”

“…Botulinum toxin type A (BTX‐A) injection has been shown to offer clinical success and has comparatively low risk of scarring; but repeated treatments are often necessary, because lesions recur when the effect of BTX‐A drops off. Pulsed dye laser treatment has been reported to induce transient or complete resolution of the lesions with minimal risk of scarring . Disadvantages include the possible need for multiple treatments.…”
