RESUMEN
RESUMEN La enfermedad de Rosai-Dorfman cutánea (ERDC) es una rara proliferación reactiva de histiocitos, que cursa con lesiones cutáneas sin compromiso generalizado. Las manifestaciones clínicas cutáneas son diversas y la variante clínica "tipo tumoración" es la forma más infrecuente. Se describe el caso de un paciente con ERDC que se presentó con esta forma inusual.
ABSTRACT Cutaneous Rosai-Dorfman disease (CRDD) is a rare reactive histiocytic proliferation, which presents with skin lesions without systemic involvement. The clinical cutaneous manifestations are diverse and the "tumor-like" clinical variant is the most infrequent. We describe the case of a patient with CRDD who presented with this unusual form.
RESUMEN
Se presenta una paciente de 50 años de edad con lesión tumoral redondeada, no dolorosa en región inguinal, con crecimiento progresivo y formación de una placa eritematosa, con áreas de pigmentación e infiltración de tejidos profundos, así como aparición de otras lesiones de aspecto tumoral. El estudio anatomopatológico evidenció un infiltrado histiocitario con fenómenos de linfohistiofagocitosis (emperipolesis) y el inmunohistoquímico mostró positividad para vimentina, S-100, CD68 y lisozima. Se revisó la evidencia científica disponible en la literatura mundial para determinar las manifestaciones clínicas más frecuentes, así como los medios diagnósticos más empleados en la actualidad y el tratamiento de esta enfermedad. Es importante considerar a la enfermedad de Rosai-Dorfman cutánea como un posible diagnóstico para lo que es indispensable un profundo estudio de la biopsia, así como la realización de estudios de inmunohistoquímica, dada la benignidad y buen pronóstico que la caracterizan
A 50 year-old patient with a painless round tumoral lesion on inguinal region with progressive growth and formation of an eritematous plaque with areas of pigmentation, infiltration of deep tissues and apparition of other lesions with tumoral aspect is described. The anatomopathological study showed a hystiocitic infiltrate with linfohystiofagocitosis phenomenon (Emperipolesis) and the immunohystochemical made evident positive for Vimentine, S-100, CD68 and Lisozime. The available scientific evidence of the international literature was reviewed to determine the most frequent clinical manifestations of this disease, as well as most updated means of diagnosis employed and the treatment of this disease. It is important to consider the cutaneous Rosai-Dorfman disease as one of the possible diagnosis so a profound study of the biopsy is essential, as well as the immunohystochemical studies due to the mildness and good prognosis of this disease

Relata-se o caso de uma paciente com doença de Rosai-Dorfman cutânea que apresentava na região glútea direita uma placa eritemato-acastanhada infiltrada com áreas amareladas e pápulas eritemato-acastanhadas perilesionais. O exame anatomopatológico revelou infiltrado inflamatório predominantemente de linfócitos e histiócitos de citoplasma amplo, claro e contendo células inflamatórias íntegras (emperipolese). Nenhuma outra alteração ao exame físico e laboratorial foi encontrada. A doença de Rosai-Dorfman é uma forma rara de proliferação histiocitária e o acometimento estritamente cutâneo é ainda mais raro. Sua etiologia é desconhecida e a correlação clinicopatológica permitiu o diagnóstico dessa enfermidade.
We report a patient with cutaneous Rosai-Dorfman disease that presented on the right buttock, a red brown plaque with yellowish areas and red-brown satellite papulas. The histopathologic exam revealed inflammatory infiltrate predominantly of lymphocytes and histiocytes with wide and clear cytoplasm containing intact inflammatory cells (emperipolesis). Any other alteration in the physical exam and laboratorial was not found. The Rosai-Dorfman disease is a rare form of histiocytic proliferation and the strictly cutaneous form is still rarer. The aetiology is unknown and the clinical and histologic correlation enables the correct diagnosis.
