RESUMO -Dois casos de neuropatia sensitiva e autonômica hereditária do tipo 2 são descritos. Este tipo de neuropatia faz parte de um grupo constituído por cinco entidades diferentes. A sistematização destas neuropatias depende de múltiplos critérios como idade de início, aspectos genéticos, manifestações clínicas, aspectos eletroneuromiográficos e patológicos. Neste relato descrevemos dois irmãos com 27 e 35 anos de idade que foram acompanhados em nosso Serviço, com quadro de insensibilidade à dor e conseqüentes deformidades de membros e distúrbios sensitivo-tróficos. Para estes pacientes foi definido o diagnóstico de neuropatia sensitiva e autonômica hereditária do tipo 2, com modalidade de transmissão hereditária autossômica recessiva. A idade de início do quadro, os aspectos hereditários, as manifestações clínicas e os aspectos eletroneuromiográficos são analisados. O diagnóstico diferencial com outras neuropatias sensitivas hereditárias e adquiridas é considerado.PALAVRAS-CHAVE: neuropatias sensitivas hereditárias, neuropatia autossômica recessiva, acropatia úlcero-mutilante. Hereditary sensory and autonomic neuropathy type 2: two cases reportABSTRACT -Two cases of hereditary sensory and autonomic neuropathy type 2 are reported. This type of neuropathy is included in a group that consists of five different entities. The systematization of that neuropathies depends on multiple criteria such as age of beginning, genetic aspects, clinical manifestations, eletroneuromyographic and pathologic features. In this report we describe the cases in a family, two brothers, 27 and 35 years old that were observed in our department with pain insensibility and consequent sensitivetrophic disturbs and deformity of members. The diagnoses was defined as hereditary sensory and autonomic neuropathy type 2 and an inherited pattern recessive autossomic transmission was considered. The age of beginning, the hereditary aspects, the clinical manifestations and the eletroneuromyographic features are analysed. The differential diagnoses with other sensory hereditary and acquired neuropathies is emphasized.
