| WKP | PO |
Definition: Hidrocystoma is a cyst of the sweat glands. Hidrocystomas are cysts of sweat ducts, usually on the eyelids. They are not tumours (a similar-sounding lesion called hidroadenoma is a benign tumour).
Hidrocystomas usually arise from apocrine glands. They are also called Cysts of Moll or sudoriferous cysts. There may be a type of hidroadenoma that arises from eccrine glands, but these are uncommon.
Other related conditions on the eyelids include chalazion ( a granulomatous reaction to sebaceous glands on the eyelid), lacrimal duct cysts (cysts related to tear ducts) and nasolacrimal duct cysts (the nasolacrimal duct drains tears into the nose via a punctum on the lower eyelid).
An eruption of deeply seated vesicles, due to retention of fluid in the sweat follicles. Hydrocystoma is produced by the cystic proliferation of secretary apocrine or eccrine glands and is a usually solitary, dome-shaped translucent nodule that typically shows a bluish-gray color.
Hydrocystomas occur on the eyelids. They typically are the same color as eyelid skin, rounded and soft to the touch. They are slow growing and do not cause loss of eyelashes. Cystic lesion of the either apocrine or eccrine sweat glands.

Synopsis
Usually presents as a solitary and translucent cyctic nodule containing serous or milky secretions
Common in the periocular skin, lesions are asymptomatic.
Apocrine hidrocystoma originate from the blocked excresion of the glands of moll, may occasionally encountered as multiple lesions and usually found on the lid margin.
Eccrine hidrocystoma are regarded as less common ductal retension cysts that are not confined to the lid margin.
Types
apocrine hidrocystoma
- Apocrine hidrocystoma originate from the blocked excresion of the glands of moll may occasionally encountered as multiple lesions and usually found on the lid margin.
eccrine hidrocystoma
- Eccrine hidrocystoma are regarded as less common ductal retension cysts that are not confined to the lid margin.
