Resumen
Antecedentes: las dermatosis perforantes reactivas (DPR) se caracterizan por presentar el fenómeno de eliminación transepidérmica. Clásicamente se han reconocido 4 variedades clínicohistológicas; sin embargo, en los últimos años se ha agregado un quinto grupo llamado “dermatosis perforante adquirida”. Objetivo: estimar la frecuencia, las características histológicas, clínicas y epidemiológicas de las DPR en 55 años, en el Centro Dermatológico Dr. Ladislao de la Pascua (CDP). Material y método: se realizó un estudio retrospectivo de 55 años en el laboratorio de Dermatopatología del CDP y se seleccionaron las biopsias con diagnóstico de DPR, registrando datos epidemiológicos, clínicos e histológicos. Resultados: se encontraron 9 biopsias con diagnóstico de DPR. En 3 pacientes se registró asociación con diabetes mellitus (DM) descontrolada e insuficiencia renal crónica (IRC) secundaria. De acuerdo a los hallazgos histológicos y tinciones especiales obtuvimos: 5 casos de enfermedad de Kyrle, 2 de colagenosis perforante reactiva, 1 caso de elastosis perforante serpiginosa y 1 caso de foliculitis perforante. Conclusión: para realizar el diagnóstico correcto, se debe identificar el tipo de material que presenta eliminación transepidérmica mediante tinciones especiales y realizar una adecuada correlación clínico-patológica. Palabras clave: dermatosis perforantes reactivas, eliminación transepidérmica, enfermedad de Kyrle, colagenosis perforante reactiva, elastosis perforante serpiginosa, foliculitis perforante.

Abstract
Background: RPD are characterized by a phenomenon of transepidermal elimination. Classically there have been four clinicalhistopathological varieties, however in recent years a fifth group has been added called “Acquired Perforating Dermatosis”. Objective: To estimate frequency and the clinical, epidemiological and histological characteristics of RPD in 55 years, at our dermatological center Dr. Ladislao de la Pascua (CDP). Material and method: A retrospective study of 55 years was made in the Dermatopathology department of the CDP. Biopsies with diagnosis of RPD were studied, registering epidemiological, clinic and histological data. Results: There were 9 biopsies with the diagnosis of RPD. In 3 patients association with uncontrolled diabetes mellitus (DM) and secundary cronic renal failure (IRC). According to the histological findings and special stains we obtained: 5 cases of Kyrle disease, 2 of active perforating collagenosis, 1 case of perforating serpiginous elatosis and 1 case of perforating folliculitis. Conclusion: To obtain the correct diagnosis, the material that presents transepidermal elimination must be identified by special stains and an adequate clinical-pathological correlation must be made. Key words: acquired perforating dermatosis, transepidermal elimination, Kyrle disease, active perforating collagenosis, perforating serpiginous elastosis, perforating folliculitis.
