There are several case reports of localized unilateral hyperhidrosis caused by this type of nevus. Another emerging treatment in axillary hyperhidrosis is fractionated microneedle radiofrequency. Histologic exam reveals hyperplastic eccrine glands but only rarely increased numbers of glands. This sweat is 'watery' rather than stinky. Sometimes the sweating only occurs at the gluteal fold (the butt crack), and sometimes it also includes the area between the anus and the genitals. These nevi can be linear or circular and of varying size. Hexsel's hyperhidrosis usually starts in adolescence, before the age of 25.
A nevus sudoriferus, located on the face or forearms, excretes excessive sweat in response to thermal or emotional triggers. One theory is that LUH is caused by “a misdirected reconnection of the sympathetic nerve fiber network after injury, similar to Frey syndrome.”Ī functional nevus has also been found to be associated with focal hyperhidrosis. Sweating occurs spontaneously and during sleep. This rare type of hyperhidrosis differs from primary hyperhidrosis in that there are no triggers. In an idiopathic form of excessive sweating, localized unilateral hyperhidrosis (LUH), excessive sweating occurs in a small area of the forehead or forearm. This type of sweating is due to a direct axon reflex that occurs around the border of painful lesions.

Localized sweating around these types of lesions as well as painful skin ulcers may be the basis of axon-reflex sweating. Hyperhidrosis can be seen in skin overlying a blue rubber bleb nevus and in skin adjacent to glomus tumors. Hyperhidrosis can also be seen with nail-patella syndrome, a disorder involving hypoplastic nails, bony abnormalities including hypoplastic patellae, and renal disease. Several subtypes of a rare ectodermal dysplasia, pachyonychia congenita, are associated with palmoplantar hyperhidrosis, as is pachydermoperiostosis, in which patients appear to have acromegaly with finger clubbing, periosteal new bone formation, and coarsened facial features. In POEMS syndrome, seen primarily in the Japanese population, patients have polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes accompanied by hyperhidrosis. Rare syndromes with dermatologic symptoms can be associated with focal hyperhidrosis.
