Polimorfismo das lesões dermatológicas na blastomicose de Jorge Lobo entre os índios Caiabí

Abstract

SINOPSESão estudados casos de blastomicose de Jorge Lobo encontrados entre índios Caiabí vivendo numa alãeia nativa à margem do rio Tatui (Amazônia Mato Grossense). Aqueles índios não devem ser confundidos com os Caiabí estudados por outros Autores no Parque do Xingu. Foram encontrados cinco quadros dermatológicos distintos e que o Autor divide em dois grupos polares : um grupo hiperêrgico (formas maculosas e gomosas) e um grupo hipoergico, forma queloidiforme. É enfatizada a conveniencia do estudo da classificação das formas clínicas, já proposta por D . Silva, como elemento básico para melhor interpretação das diferentes observações e como ponto de partida para pesquisas imunológicas indispensáveis à melhor compreensão da Doença de Jorge Lobo. MATERIAL E MÉTODOS

Lobomycosis: an emerging disease in humans and delphinidae

“…1b and 1c). 48–52 The lesions may be single or multiple. They have a tendency to become confluent over extensive areas of the body surface 51,52 .…”

“…They have a tendency to become confluent over extensive areas of the body surface. 51,52 Although a specific pattern may dominate any given case, lesions are rarely monomorphous. 4,49,50 Silva [53] and De Brito [53,54] proposed a classification based on the morphological appearance of the lesions into five subtypes: infiltrated, keloidal, gummatous, ulcerative and verrucoid.…”

“…8 They are generally painless, hypo or hyperchromic, 4,52 although pruritus and dysesthesias have been occasionally described. 51,52 Borelli describes the occurrence of pain as acute and sudden, similar to that produced by the bite of a large Amazonian ant (Atta Sexdens), penetration of pliers, or a hard blow on a keloid. 21 Regional lymph nodes can be affected, 43,44 but systemic involvement is apparently rare with only one case (as mentioned earlier) described in the literature that developed extensive lower limb lesions in a 47 year period and later developed testicular metastasis.…”

Tropical dermatology: Fungal tropical diseases

“…23 On the other hand, it is a rare disease among the Caiabi Indians (56 cases in the last 30 years) who live in the central highlands of Brazil. 4,24 The disease is usually found in tropical, humid, or subtropical forests with elevations greater than 200 meters, an average temperature of 248C, and more than 200 cm of annual rainfall. 3,4 The agent probably is introduced directly into the dermis through a penetrating injury, such as a thorn prick or an insect bite.…”

“…3,5,[6][7][8][9]32 Ulcerations and gummatous lesions are not common, 22,32 but some verrucous lesions are often seen. 22,24 The increase in size and number of lesions is a slow process and can take several decades. 24 No deaths from lobomycosis have been reported.…”
