RESUMEN
Resumen El liquen mixedematoso (LM) representa un grupo de enfermedades cutáneas raras, el cual se encuentra dentro de las mucinosis crónicas. Anteriormente descrita como escleromixedema localizado, sin embargo, a diferencia de éste, por lo general no tiene compromiso sistémico. Dentro de los subtipos, se encuentra el LM atípico, el cual es infrecuente y hay pocos casos reportados asociados a mieloma múltiple (MM). Se presenta el caso de un paciente masculino con MM positivo para cadenas lambda, con cuadro clínico de inicio agudo, en quien se realizó diagnóstico de LM atípico; recibió manejo con corticoide tópico con mejoría de las lesiones al mes de tratamiento.
Abstract Lichen myxedematous (LM) represents a group of rare skin diseases, which is found within the chronic mucinoses. Previously described as localized scleromyxedema, however, unlike localized scleromyxedema, it usually does not have systemic involvement. Among the subtypes, there is atypical LM, which is infrequent and there are few reported cases associated with multiple myeloma (MM). We present the case of a male patient with MM positive for lambda chains, with acute onset clinical picture, who was diagnosed with atypical LM; he received management with topical corticosteroid with improvement of the lesions after one month of treatment.
RESUMEN
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease, with a low prevalence worldwide. There is little epidemiologic information available on this disease in Latin America, including Colombia. The aim of this study was to estimate the prevalence and describe the main demographic characteristics of HS in Colombia. This was a cross-sectional descriptive study using the code of the International Classification of Diseases (ICD-10) for HS (L732). For this study, data from the Comprehensive Social Protection Information System of the Ministry of Health of Colombia, which is the database on diagnoses made by physicians in all medical institutions of the country, were analyzed for the period 2013-2017. A total of 3,667 patients of HS were reported in Colombia, with a prevalence of 7.4/100,000 inhabitants; 68% of the patients affected were women, with a woman to man ratio of 2.1:1. The highest prevalence was in the age group of 35-39 years. Among the departments of Colombia, the highest prevalence was in Caldas, with 17 patients per 100,000 inhabitants. Ours was the second study conducted in Latin America on the epidemiology of HS. We found a low prevalence of HS, which was even lower than that reported in studies from other countries.
