Pellagra (vitamin B6 deficiency) is seen in chronically malnourished patients and deserves attention because of its multisystemic involvement. We report a case of a 48-year-old male patient with chronic alcohol abuse, diarrhea, insomnia, irritability and memory impairment. On physical examination, there were symmetrical, erythematous, desquamative and edematous lesions on the dorsum of both feet and anterior and posterior aspects of the legs, sparing the area covered by the shorts and slippers straps. After 20 days of niacin and B complex replacement, there was marked improvement in skin lesions, but the digestive and neurological symptoms did not improve. Aspects concerning pathogenesis, pathophysiology, differential diagnosis and treatment of pellagra are discussed. Diagnosis of pellagra should be considered in patients with skin lesions and risk factors for malnourishment, such as alcoholic and chronically ill patients.
A pelagra (deficiência de vitamina B6) acomete pacientes cronicamente desnutridos e merece destaque por seu envolvimento multissistêmico. É relatado o caso de um paciente de 48 anos, sexo masculino, com história de alcoolismo crônico, diarréia, insônia, irritabilidade e diminuição da memória. Ao exame físico, apresentava lesões eritematodescamativas, edemaciadas, simétricas no dorso de ambos os pés e região anterior e posterior das pernas, poupando a área da bermuda e as tiras dos chinelos. Após 20 dias de reposição de niacina e complexo B, apresentou melhora significativa das lesões de pele, sem melhora dos sintomas digestivos e neurológicos. Os aspectos da patogênese, fisiopatologia, diagnóstico diferencial e tratamento da pelagra são discutidos. O diagnóstico de pelagra deve ser lembrado em pacientes com lesões de pele e fatores de risco para desnutrição, como pacientes alcoolistas e doentes crônicos.
