Acquired idiopathic generalized anhidrosis: clinical manifestations and histochemical studies.

A 40-year-old male developed complete absence of sweating except for slight sweating in the axillar region. Histopathologic examination of the skin revealed lymphocytes infiltration around the sweat glands and coarse and irregular arrangement of the eccrine glands. Immunohistochemical staining using anti-CD3, CD4, and CD8 antibodies revealed that CD3 positive cells were dominant in the lesion. After intensive glucocorticoid treatment, generalized sweating was almost completely recovered.
