Acquired idiopathic generalized anhidrosis (AIGA) is characterized by generalized absence of sweating without other autonomic and neurologic dysfunction.[1]

AIGA is classified into 3 subgroups: idiopathic pure sudomotor failure (IPSF), sweat gland failure (SGF), and sudomotor neuropathy, with each subgroup presenting a different pathogenesis.[2][3][4]

Diagnosis

Quantitative sudomotor axon reflex test and microneurography are used in the diagnosis of AIGA. However, these refined methods are mostly used for research purposes and not generally available.[5]

Skin biopsy analysis may play a crucial role in the identification of AIGA subgroups.[1]
