RESUMO

Rosai-Dorfman Disease (RDD) is a rare non-Langerhans histiocytosis, usually self-limited and presenting with massive, painless, bilateral cervical lymphadenopathy, with or without constitutional symptoms. Extranodal disease is frequently present, and may happen in the absence of lymph node involvement, symptomatology and differential diagnosis will depend on the site affected and fatal cases may occur. The authors present two cases of Rosai-Dorfman disease (RDD), diagnosed through immunohistochemistry, with different progressions, one with complete remission and one culminating in death, highlighting the variety of presentations and the diagnostic difficulty. RDD is a rare condition with clinical presentations similar to several diseases, and should be considered in the differential diagnosis of lymphadenopathy with extranodal lesions.

RESUMO

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.

RESUMO

Introducción: la enfermedad de Rosai-Dorfman, conocida como histiocitosis sinusal con linfadenopatía masiva, es una variedad muy rara de las histiocitosis reactivas de origen desconocido. Presentación del caso: paciente femenina de 32 años de edad quien consultó por dificultad respiratoria, voz ronca, estridor y múltiples zonas inflamadas en cuello y tronco desde hace 5 años. Al examen físico se detectaron ganglios linfáticos grandes, firmes y móviles submandibulares y múltiples nódulos en tronco. El examen histológico mostró características típicas de enfermedad de Rosai-Dorfman con afección ganglionar y extraganglionar. Discusión: es un proceso patológico que afecta los ganglios linfáticos cervicales, aunque puede haber lesiones en varias regiones, órganos y sistemas, lo cual puede confundirse con otras neoplasias. Debe considerarse en el diagnóstico diferencial de lesiones histiocíticas de tejidos blandos y otros trastornos linfoproliferativos. La mortalidad ocurre por la alteración funcional de órganos y sistemas más que por la propia enfermedad. Conclusión: la enfermedad de Rosai-Dorfman con afección ganglionar y extraganglionar es un trastorno histiocítico proliferativo benigno muy raro. Es importante considerarla como diagnóstico diferencial de otras enfermedades histiocíticas proliferativas. Su pronóstico es variable pero relativamente benigno.


Introduction: Rosai-Dorfman disease, known as sinus histiocytosis with massive lymphadenopathy, is a very rare variety of reactive histiocytosis of unknown origin. Case presentation: a 32-year-old female patient who consulted for a five-year history of respiratory distress, dysphonia, stridor and multiple swollen areas in the neck and trunk. Physical examination revealed large, firm, and mobile submandibular lymph nodes and numerous nodules on the trunk. Histological examination showed the characteristic features of Rosai-Dorfman disease with nodal and extranodal involvement. Discussion: Rosai-Dorfman disease is a pathological process which affects cervical lymph nodes, although lesions may develop in several sites, organs, and systems, and may be confused with other neoplasms. It should be considered in the differential diagnosis of soft tissue histiocytic lesions and other lymphoproliferative disorders. Death is related to organs and systems dysfunction rather than to the disease itself. Conclusion: Rosai-Dorfman disease including nodal and extranodal involvement, is a very rare benign proliferative histiocytic disorder. It should always be included in the differential diagnosis of other histiocytic proliferative disorders. It carries a variable relatively benign prognosis.

RESUMO

Rosai Dorfman Destombes (RDD) disease is a non-Langerhans histiocytosis. The central nervous system is affected in < 5% of cases. We report the case of a 59-year-old man, who began 8 months before admission with headache, diminished visual acuity in the temporal hemifields, hyposmia, and seizures. Magnetic resonance imaging showed three midline skull-base lesions in anterior, media, and posterior fossae. We performed a complete resection of symptomatic lesions using a bifrontal craniotomy. The histopathological analysis determined RDD, therefore, we started steroid treatment. Our case description is due to the diagnosis and location, one of the rarest reported to date in the literature.


La enfermedad de Rosai-Dorfman-Destombes (RDD) es una histiocitosis no Langerhans. El SNC se ve afectado en menos del 5% de los casos. Presentamos el caso de un hombre de 59 años quien inició ocho meses previos al ingreso con cefalea, hemianopsia bitemporal, hiposmia y convulsiones. La resonancia magnética mostró tres lesiones de la base del cráneo en las fosas anterior, media y posterior. Realizamos una resección completa de las lesiones sintomáticas mediante una craneotomía bifrontal. El análisis histopatológico determinó RDD. Nuestro caso es debido al diagnóstico y localización, uno de los más raros reportados hasta la fecha en la literatura.

RESUMO

PURPOSE: To describe the clinical features and histopathologic findings of Rosai-Dorfman disease (RDD) with ophthalmic involvement diagnosed at a Mexican ophthalmologic referral center in a period of 62 years. RESULTS: A total of 17 cases of RDD with ophthalmologic manifestations in Mexican-mestizo patients were collected. Female predominance was observed in 12 of 17 patients. The mean age was 36 years with a range of 12-76 years. The median age at presentation was 32 years. The orbit was the most affected location with 15 cases. Conjunctival disease was seen in 4 cases: two as isolated lesions, the rest with orbital or uveal involvement . One case suggested choroidal RDD associated to conjunctival and orbital lesion. Three cases presented multifocal disease. A patient with orbital affection developed extranodal disease elsewhere. No concurrent lymphadenopathy was observed in any patient.Histopathological examination revealed classic RDD findings in all cases: A polymorphous cellular infiltrate composed by lymphocytes, plasma cells and large histiocytes with emperipolesis hallmark of the disease. Immunohistochemically, histiocytes were positive for S-100 protein and CD68 in 15 cases. CONCLUSION: RDD of the eye and ocular adnexa in Mexican-mestizo patients is common in middle-aged women frequently as an isolated orbital lesion. Histopathology is necessary for accurate diagnosis. Most patients had a favourable outcome after medical and surgical treatment. To the best of our knowledge this is the largest case series of RDD of the eye and ocular adnexa in Latin-American patients.

RESUMO

Rosai-Dorfman-Destombes disease (RDD) is a rare non-Langerhans cell histiocytosis, with sinus involvement and massive lymphadenopathy. RDD is usually self-limited; it can appear alone or related to other diseases. We present a 9-year-old male with biopsy of that lesion was taken, giving as result a benign histiocytosis, compatible with RDD. The patient was scanned with full body 18F-FDG PET/CT, the results of the study showed hypermetabolic focal lesions in the sphenoid sinus, ethmoid sinus, and bilateral nasal involvement with hypermetabolic focal injury in the middle third of the left tibia, findings in relation to high-grade expansive injury. The study of 18F-FDG PET/CT demonstrated avid FDG lesions at nodal and extranodal sites, and it also can be used in monitoring and/or evaluating response to treatment.


La enfermedad de Rosai-Dorfman-Destombes (RDD) es una rara histiocitosis de células no Langerhans, con compromiso de los senos nasales y linfadenopatías masivas. RDD es usualmente autolimitada, y puede aparecer sola o asociada a otras enfermedades. Se presenta el caso de un niño varón de 9 años cuyo resultado histopatológico mostró histiocitosis benigna compatible con RDD. El paciente se sometió a una Tomografía Computarizada/Tomografía de Emisión de Positrones con 18F-fluorodeoxyglucosa (18F-FDG-TEP/TC) de todo el cuerpo, que mostró lesiones focales hipermetabólicas en los senos esfenoidales, etmoidales, y nasales bilaterales, junto a una lesión focal hipermetabólica en el tercio medio de la tibia izquierda. El estudio con 18F-FDG-PET/CT pudo demostrar lesiones ávidas de glucosa en sitios nodales y extra-nodales, y también puede servir en la monitorización o evaluación de la respuesta al tratamiento.

RESUMO

The case is presented on a 52-year-old male patient, who was seen in the Rheumatology department. He had painless lymph nodes in the cervical, axillary, supraclavicular, and neck region. He also had a fever, and parotid and submaxillary gland enlargement. Complementary studies were performed, showing normocytic-normochromic anemia, thrombocytopenia and eosinophilia, impaired renal function with hypoalbuminaemia and hematuria, ANA 1/5120, Sm+, ACL+. Biopsies were also performed on the compromised tissues, reaching the diagnosis of Rosai-Dorfman Disease and IgG4-related Disease. Differential diagnoses of cervical, axillary and inguinal lymph nodes, with fever, renal and hematological compromise are discussed.

RESUMO

The Rosai-Dorfman disease (RDD) is a bening entity, of unknown etiology, rare, characterized by the overproduction of histiocytes and their subsequent accumulation in the lymph nodes, which may also compromise other organs and systems. It predominantly affects young people. The histological study, which shows emperipolesis, is very indicative but not pathognomonic, but with the immunohistochemistry the diagnosis of the disease is reached, which does not have a well-protocolized treatment. Its evolution is highly variable, with spontaneous remission being a possibility, although in some cases the commitment is extensive, compromising important or vital anatomical structures that requiere vigorous treatment, which can be surgical, radiotherapy and even chemotherapy. We present a case of RDD that affected a 17-year-old girl with upper jaw and right maxillary sinus commitment, which began with loss of teeth, and subsequent appearance of a painless and deforming facial tumour that underwent surgical resection. In this case, the etiological diagnosis was not posible in the preoperative period despite multiple biopsies. An extensive review of the literature is carried out in order to a better understanding of this pathology.


La Enfermedad de Rosai-Dorfman (ERD) es una entidad benigna, de etiología desconocida, poco frecuente, caracterizada por la sobreproducción de histiocitos y su posterior acúmulo en los linfonodos, pudiendo comprometer también a otros órganos y sistemas. Afecta predominantemente a personas jóvenes. El estudio histológico, que muestra emperipolesis, es muy orientativa pero no patognomónica, aunque con la Inmunohistoquímica se llega al diagnóstico de la enfermedad que no tiene un tratamiento bien protocolizado. Su evolución es muy variable, siendo la remisión espontánea una posibilidad, no obstante, en algunos casos, el compromiso es extenso, comprometiendo estructuras anatómicas importantes o vitales que requieren de un tratamiento enérgico, pudiendo ser éste quirúrgico, radioterápico y aún quimioterápico. Se presenta un caso de ERD que afectó a una joven de 17 años, con compromiso de maxilar y seno maxilar derecho, que debutó con pérdida de piezas dentarias y posterior aparición de un tumor facial indoloro y deformante que fue sometido a resección quirúrgica. En este caso no fue posible el diagnóstico etiológico en el preoperatorio pese a múltiples biopsias. Se hace una extensa revisión de la literatura con el objeto de conocer mejor esta patología.

RESUMO

Resumen La histiocitosis sinusal con linfadenopatías masivas, conocida como enfermedad de Rosai-Dorfman (ERD), es una patología poco frecuente cuya presentación clásica consiste en el desarrollo de grandes adenopatías cervicales bilaterales indoloras. La manifestación extranodal puede involucrar compromiso cutáneo, del sistema nervioso central, hematológico, óseo, de la vía aérea, entre otros. Su diagnóstico es un desafío y requiere una evaluación completa del paciente incluyendo historia clínica, examen físico, exámenes de laboratorio, imágenes y estudio histopatológico que confirme el diagnóstico. El tratamiento debe ser individualizado para cada paciente. Las alternativas incluyen la observación, corticoides sistémicos, radioterapia, quimioterapia, inmunomoduladores y cirugía. Se presenta el caso de una paciente de 65 años con antecedente de enfermedad de Rosai-Dorfman localizada en glándulas lagrimales y linfoma no Hodgkin, que comienza con obstrucción nasal bilateral progresiva refractaria a tratamiento médico, por lo que se decide realizar cirugía, cuyo estudio histopatológico confirmó enfermedad de Rosai-Dorfman.


Abstract Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare pathology, with a classic clinical presentation of painless bilateral massive cervical lymphadenopathy. The extranodal manifestations may involve skin, central nervous system, hematological, bones, and airway compromise, among others. Its diagnosis is challenging and requires a complete evaluation of the patient including medical history, physical examination, laboratory testing, imaging and histopathological study to confirm the diagnosis. Treatment should be individualized for each patient, including follow-up, systemic corticosteroids, radiotherapy, chemotherapy, immunomodulators and surgery. We present the case of a 65-year-old patient with a history of RDD located in the lacrimal glands and lymphoma, which begins with progressive bilateral obstruction refractory to medical treatment, for which it is decided to perform surgery, whose histopathological study confirmed RDD.
