Conidiobolus coronatus infection treated with ketoconazole.

We describe a case of subcutaneous zygomycosis caused by Conidiobolus coronatus of six years' duration. Following treatment failure using potassium iodide, the patient responded with ketoconazole therapy. She remained well three years following therapy. Brazilian cases of subcutaneous infections caused by C coronatus and Basidiobolus ranarum are reviewed.

Tuberculose cutanea indurativa de Bazin. / Bazin's erythema enduratum

Foi nossa proposta a etiologia controvertida do eritema indurado de Bazin e, para isto, realizamos revisao do material existente nos Servicos de Dermatologia da Policlinica Geral do Rio de Janeiro, da Santa Casa de Misericordia, da Universidade Federal do Rio de Janeiro de da Universidade Federal Fluminense. Incluimos no nosso material o metodo tintorial proposto por NYKA, a fim de comprovar sua sensibilidade na evidenciacao de mycobacterias.Os criterios de tuberculose foram revistos e comparados com aqueles adotados para o diagnostico de outras infeccoes principalmente da hanseniase. Os criterios presuntivos de diagnostico da tuberculose cutanea propostos por F.E. Rabello foram analisados e aplicados a nossa causistica

[Comparative analysis of the clinical diagnosis of hanseniasis and the histopathological examinations performed according to the criteria of the Madrid and Ridley-Jopling classifications]. / Análise comparativa entre o diagnóstico clínico da hanseníase e os exames histopatológicos realizados segundo os critérios da classificação de Madrid e a de Ridley-Jopling.

A comparative study of the Ridley-Jopling's (RJ) and of the Congress of Madrid's (CM) pathological criteria was made in the different clinical types and groups of hanseniasis. A concordance between both criteria was found in the Indeterminate group and in the regressive phases of the Virchowian (V), Tuberculoid (T) and Reactional tuberculoid (RT) types. Clinical RT was confirmed by pathology in 81.2% of the cases according to CM, whereas 46.2% were considered "Borderline" according to RJ. Out of the 48 clinically V patients, 17 (35.4%) were "Borderline" (BL-2, BL-1 and BB), but practically all were also pathologically V according to CM. It is concluded that there is no practical convenience in the establishment of histopathological sub-groups that do not perfectly agree with clinical criteria. The Authors stress the importance of the study of the plasmocytes in the V infiltrates, of the lymphocytes in all granulomas and of the differences in the involvement of the neural ends, specially between the T and V poles. The dyeing of lipids by the Sudan III is useful to perfectly characterize the V pole, recognize residual V structures, separate the sub-groups BT, BB and BL, help in the early diagnosis of V infiltrations and differentiate the edematous, diffuse, non-granular cytoplasmatic vacuolization of RT.
