TY - JOUR T1 - Dapsone-induced motor polyneuropathy: A complication of prolonged treatment of subcorneal pustular dermatosis AU - Fredericks EJ, Kugelman TP, Kirsch N Y1 - 1976/08/01 N1 - 10.1001/archderm.1976.01630320064020 JO - Archives of Dermatology SP - 1158 EP - 1160 VL - 112 IS - 8 N2 - • A motor polyneuropathy developed in a woman with subcorneal pustular dermatosis of 16 years' duration, who had received at least 300 gm of dapsone over a five-year period and 80 gm during the four-month period of progression of her neurologic symptoms. Although the patient believed her muscle power had returned to normal four months after the drug was stopped, a slight peripheral neuropathy remained. Electrodiagnostic and clinical features during the period of greatest weakness and the subsequent 16 months were consistent with a polyneuropathy of the axonal type. The neurotoxicity of dapsone appears to be dosedependent, but the mechanism by which it occurs is unknown.(Arch Dermatol 112:1158-1160, 1976) SN - 0003-987X M3 - doi: 10.1001/archderm.1976.01630320064020 UR - http://dx.doi.org/10.1001/archderm.1976.01630320064020 ER -
