Hidrocystoma Hidrocystoma Hidrocystoma (also known as cystadenoma, a Moll's gland cyst, and a sudoriferous cyst) is an adenoma 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). There are three types of "sweat" glands: True sweat glands or eccrine glands; sebaceous glands, which have an oily secretion around hair follicles; and apocrine glands which have more oily product than eccrine glands and are found on the face, armpit, and groin. Hidrocystomas usually arise from apocrine glands. They are also called Cysts of Moll
Seam sealant Seam sealant Seam sealants are chemical coating compositions. Seam sealing was already performed manually successfully for preventing perforation corrosion in the 1980s. Today used in the OEM automotive industry primarily for the purpose of seals against air leaks and to waterproof sheetmetal overlaps that occur in the assembly of a vehicle. Such overlaps are typically decorative rather than structurally supportive. Accordingly, they are usually only spot welded and this process results in a closure that is not air or water tight. Seam sealants are sprayed or extruded over the joined edges of these overlaps, and they then either cure to
