Follicular mucinosis: an important differential diagnosis of leprosy in an endemic area

Primary follicular mucinosis is a rare dermatosis characterized by the accumulation of mucin in the follicular epithelium and sebaceous glands. Clinically, it is characterized by the presence of papules or well-circumscribed and infiltrated plaques. In this paper, we report the case of a female patient, seven years old, evolving for three months with an asymptomatic, erythematous and infiltrated plaque located in the chin region. The research of thermal, pain and tactile sensitivity was inconclusive. Histological findings confirmed the diagnosis of follicular mucinosis. There was regression of the lesion with the use of medium potency topical corticosteroids for 20 days. The pathogenesis of follicular mucinosis remains unknown, being in some cases associated with lymphoproliferative disorders. In endemic areas of leprosy, isolated and infiltrated follicular mucinosis lesions should be further differentiated from leprosy.

Compreensão da importância do exame ocular preventivo entre hansenianos de duas Instituições de referência / Comprehension of the importance of preventive ocular exam among Hansen´s disease patients from two referral centers

Objetivo. Avaliar o conhecimento dos pacientes portadores de morbus Hansen, da necessidade da realização de exames oftalmológicos periódicos, visando à prevenção das complicações oculares relacionadas à sua patologia. Métodos. Avaliados 113 pacientes ambulatoriais com diagnóstico prévio de hanseníase, sendo 57 casos provenientes do Hospital Universitário de Brasília, e 56 pacientes provenientes da Fundação Instituto de Dermatologia Tropical e Venereologia Alfredo da Mata FUAM (centros de referência regional em dermatoses e hanseníase). Após assinatura de termo de consentimento livre e esclarecido, foram estimulados a responder questionário elaborado especificamente para este estudo. Também foram examinados os prontuários desses doentes para averiguar os dados de identificação, o nível de escolaridade, a forma clínica, e a duração da hanseníase. Resultados. Quando questionados se sabiam que sua doença pode levar ao aparecimento de complicações oculares, 24,8% dos entrevistados afirmaram que têm conhecimento dessa associação, 23% afirmaram desconhecer tal associação e 52,2% não souberam responder. Conclusões. Este estudo mostra ser inadequado o nível de compreensão dos enfermos com hansenníase com relação à sua doença quanto à possibilidade do aparecimento de complicações oculares. Enfatiza a necessidade que os profissionais de saúde envolvidos no tratamento de hanseníase informem aos pacientes, de forma clara, incisiva e objetiva, que a doença é potencialmente causadora de graves complicações oculares.

Objective. To evaluate the knowledge of Hansen disease patients on the demand of periodical ocular exams aiming at preventing eye complications related to their disease. Methods. A total of 113 outpatients with previous leprosy’s diagnostic, 57 from Hospital Universitário de Brasília and 56 from Fundação Instituto de Dermatologia Tropical e Venereologia Alfredo da Mata (both regional reference centers for dermatological diseases and leprosies), after signing an informed consent, the patients were stimulated to answer a specially elaborated questionnaire. Their records were examined to access personal information, school level, the clinic type of Hansen disease, and the length of the disease. Results. When asked if they knew that their disease could lead to the emergence of eye complications, 24.8% of the subjects answered they knew about this relationship, 23% answered there was no such association to their knowledge and 52.2% answered they did not know how to answer the question. Conclusions. This study demonstrates an inadequate level of understanding on part of the studied Hansen disease patients regarding the risk of their disease to lead to further ocular complications. It also emphasizes the necessity that all health professionals who take part in treatment of Hansen disease patients should tell them clearly and objectively their disease is potentially related to important eye complications, being such information a basic and extremely helpful procedure in preventing these problems.

Queilites / Cheilitis

As autoras discutem sobre algumas formas de queilite que, por suas manifestações clínicas, freqüência e potencial de malignização, têm maior relevância tanto para o clínico geral quanto para os especialistas que lidam diretamente com lesões da mucosa oral - como os dermatologistas, otorrinolaringologistas, cirurgiões de cabeça e pescoço, dentistas e estomatologistas, entre outros
