Case for diagnosis. Pruritic erythematosquamous lesion in the auricle,
Abstract Chromoblastomycosis is a subcutaneous mycosis with chronic evolution that mainly affects the lower limbs and, less frequently, the auricles. Clinically, it presents with papillary verrucous, nodular, and/or tumoral lesions, whether isolated or infiltrated, forming plaques and, sometimes, atrophic in some areas. Histopathologically, it is characterized by a dermal granulomatous inflammatory infiltrate, and the diagnosis can be confirmed by the presence of fumagoid bodies in anatomopathological or direct mycological exams.

Cutaneous infection by Mycobacterium lentiflavum after subcutaneous injection of lipolytic formula,
Abstract The incidence of nontuberculous mycobacterial infections is increasing worldwide; by 2017, more than 190 species and subspecies have been documented. Although classically associated with immunosuppression, the recognition of these etiological agents in diseases affecting immunocompetent individuals and in healthcare-associated infections, such as after surgical and cosmetic procedures, makes the study of the epidemiology and pathogenesis of these microorganisms relevant in medical practice. Mycobacterium lentiflavum is slow-growing and rarely affects the skin. A case of cutaneous mycobacteriosis caused by M. lenti...

Epidemiological monitoring of leprosy indicators in Sergipe (2001-2015): segmented regression analysis,
This study analyzed the trend of leprosy indicators in Sergipe, between 2001 and 2015. It was a time series study that analyzed the trend for general detection coefficient, children under 15 years of age, and new cases with grade 2 disability. The joinpoint model was used. Two (2.6%) municipalities had an increasing trend in general detection coefficient, five (6.6%) had an increasing trend in detection rate in children under 15, and 19 (25.3%) had an increasing trend in detection coefficient of new leprosy cases with grade 2 disability. The findings suggest maintenance of the chain of transmission. (Source: Anais Brasileiros de Dermatologia)
