Resumo

A bullosis diabeticorum (BD) é uma manifestação cutânea infrequente do diabetes e pode afetar os membros superiores. Caracteriza-se pelo aparecimento espontâneo e indolor de flictenas não inflamatórias de aspecto sanguinolento, que podem evoluir para necrose, requerendo que se faça diagnóstico diferencial com doenças dermatológicas, como porfiria cutânea tarda, pseudoporfiria, epidermólise bolhosa adquirida e penfigoide bolhoso, e doenças vasculares, como vasculites, doença arterial periférica, doença de Buerger, entre outras. Neste relato, descreve-se o caso de um paciente masculino de 77 anos, hipertenso e diabético mal controlado, apresentando aparecimento espontâneo de lesões bolhosas de membros superiores, que evoluíram, após ruptura espontânea, para ulcerosas necróticas. A biópsia da lesão diagnosticou a presença de espessamento hialino de vasos dérmicos e de bolhas subcórneas, compatíveis com o diagnóstico de BD. Após a interrupção do tabagismo e a otimização do controle glicêmico associado a corticoterapia tópica, houve melhora, com cicatrização das lesões. A apresentação da BD em membros superiores é mais rara, sendo necessário o diagnóstico diferencial com outras lesões cutâneas e vasculares.

Abstract

Bullosis diabeticorum (BD) is an uncommon cutaneous manifestation of diabetes that can affect the upper limbs. It is characterized by spontaneous and painless non-inflammatory bloody blisters, which can progress to necrosis, requiring differential diagnosis to rule out other dermatological diseases, such as porphyria cutanea tarda, pseudoporphyria, epidermolysis bullosa acquisita, and pemphigoid, and vascular diseases, such as vasculitis, peripheral arterial disease, and Buerger’s disease, among others. In this report, we describe a 77-year-old male patient with poorly controlled diabetes and hypertension who presented with spontaneous onset of lesions on the upper limbs, initially with bullous characteristics, progressing to necrotic ulcers after spontaneous rupture. A biopsy revealed hyaline thickening of the dermal vessels and subcorneal bullae, consistent with a diagnosis of BD. After smoking cessation and optimization of glycemia control combined with topical corticosteroid therapy, the condition improved and lesions began to heal. This presentation of BD involving the upper limbs is rare, requiring differential diagnosis to rule out other cutaneous and vascular lesions.
