Postmenopausal craniofacial hyperhidrosis.

Hyperhidrosis is a condition marked by excessive sweating, which can either be localized or generalized. Primary focal hyperhidrosis (PFH) can arise from the palms, plantar feet, axillae and also from the face and scalp. PFH primarily affects a younger population of children and young adults, with the majority presenting before the age of 25 years. We report a distinct subtype of craniofacial hyperhidrosis in 20 postmenopausal women; this subtype is often under-recognized.
