Enfermedad de Mucha Habermann asociada a artritis reumatoide / Mucha Habermann disease associated with a rheumatoid arthritis

La pitiriasis liquenoide varioliforme aguda o enfermedad de Mucha Habermann es una afección cutánea rara de etiología no precisada, probablemente autoinmune, caracterizada por lesiones papulares de aparición aguda, con formación de pseudovesículas que sufren necrosis central, a veces con tendencia a formar costras. Se presentó el caso de una mujer de 36 años, con antecedentes de artritis reumatoidea, que ingresa por erupción generalizada en piel con formación de vesículas sobre fondo eritematoso, algunas coalescentes, con costras, prurito moderado y fiebre de hasta 39,2 °C, a la que se realiza biopsia de piel que confirma este diagnóstico, evolutivamente mejoran las lesiones en piel pero presenta infartos digitales propios de vasculitis de pequeños vasos, que apoya la controversial hipótesis del origen vasculítico. La paciente evolucionó favorablemente con tratamiento sintomático, por tener la enfermedad un curso autolimitado y generalmente benigno(AU)

Acute varioliform lichenoides pityriasis or Mucha Haberman disease is a rare cutaneous affection of unknown etiology, probably autoimmune, characterized by popular lesions of acute appearance with formation of pseudovesicles with central necrosis, sometimes with a trend to crusts. This is the case of a woman aged 36 with a history of rheumatoid arthritis admitted due to a cutaneous systemic eruption with formation of vesicles over erythematous arrangement, some underwent coalescence with crusts, a moderate pruritus and fever up to 39.2 °C; skin biopsy confirmed this diagnosis, skin lesions improve in a evolutionary way but with digital infarction typical of small vessels vasculitis supporting the polemic hypothesis of vascular origin. Patient evolved favourably with symptomatic treatment because of the disease has a self-limited and generally benign course(AU)

Doença de Mucha-Habermann (variante febril úlcero-necrótica) com acometimento mucoso exuberante: relato de caso / Febrile ulceronecrotic Mucha-Habermann disease with exuberant mucosal involvement: case report

A pitiríase liquenoide é dermatose incomum, idiopática, com espectro clínico-histopatológico onde inclui a forma varioliforme aguda (doença de Mucha-Habermann), sua variante febril úlceronecrótica e a forma crônica. Manifestações sistêmicas podem ocorrer na variante febril úlcero-necrótica, com relatos de casos fatais em adultos. Relata-se o caso de um paciente jovem, com diagnóstico clínico e histopatológico de doença de Mucha-Habermann, variante febril úlcero-necrótica, e acometimento mucoso exuberante, fato ocasional, mesmo nas formas mais graves de pitiríase liquenoide. Além do aspecto clínico inusitado, demonstra-se excelente resultado terapêutico, com a associação de prednisona e metotrexato.

Pityriasis lichenoides is a rare idiopathic cutaneous disorder, with a clinical-histopathological spectrum comprising the acute varioliform form (Mucha-Habermann's disease), its febrile ulceronecrotic variant, and its chronic form. Systemic manifestations may occur in the febrile ulceronecrotic variant, with reports of adult mortality. The case of a young male patient with clinical and histopathological diagnosis of Mucha-Habermann’s disease, febrile ulceronecrotic variant, with severe mucosal involvement - an occasional incidence even in the most severe forms of pityriasis lichenoides - is presented. In addition to the atypical clinical aspect, an excellent therapeutic result is shown with the association of prednisone and methotrexate.

Pityriasis lichenoides and its subtypes / Pityriasis lichenoides and its subtypes

Pityriasis lichenoides represents a unique group of inflammatory skin disorders that include pityriasis lichenoides et varioliformis acuta (PLEVA), febrile ulceronecrotic Mucha-Habermann disease (a subtype of PLEVA), and pityriasis lichenoides chronica. The history, epidemiology, clinical features, pathophysiology, and treatment of this group of conditions are reviewed in this manuscript.
