Introduction: Rosai-dorfman disease (RDD) is a self-limiting, non-Langerhans cell histiocytosis of unknown etiology. It was originally thought to involve only the lymph nodes, however recent literature suggests extranodal involvement as wel. Case Report: Herein we report a case of cutaneous RDD in a six year-old girl, presenting with multiple subcutaneous nodules. Discussion: Cutaneous RDD is an extremely rare entity and unlike classic RDD, it has a predilection for the age group above 40 years and is more common in females. It is extremely rare in children.

| Introduction|| |
Rosai-Dorfman Disease More Details (RDD) is a rare, idiopathic, benign, polyclonal proliferation of the histiocytes originally known to involve only the lymph nodes. It is also known as sinus histiocytosis with massive lymphadenopathy. However, the reports of extranodal involvement in the literature warrant it to be termed as “Rosai-Dorfman disease” more appropriately.
RDD involves lymph nodes as well as extranodal organs among which skin is the most commonly involved, but exclusive involvement of the skin is an extremely rare occurrence. Around 43% of the cases with RDD have extranodal involvement, of which 11% cases have skin involvement, whereas 3% of the cases are reported to have solely cutaneous involvement.
Cutaneous RDD is now considered to be a distinct entity with isolated skin involvement without any lymphadenopathy or systemic symptoms. We report a case of cutaneous RDD in a child presenting with multiple subcutaneous nodules.
| Case Report|| |
A 6-year-old girl presented to us with multiple asymptomatic subcutaneous nodules over bilateral lower eyelids, left cheek, upper abdomen, bilateral buttocks, and left anterior thigh [Figure 1]. The nodules developed insidiously, were progressive in nature and were gradually increasing in size for the past eight months. On cutaneous examination, the nodules were nontender, varied in size from 1 to 3 cm in diameter, were discrete, well defined and immobile, firm in consistency, and not fixed to the overlying skin. The overlying skin appeared normal without any change in color or texture. No lymphadenopathy was found. History of fever or constitutional symptoms was absent.
Routine blood, urine, and biochemical investigations were normal, except for microcytic, hypochromic anemia, and a raised erythrocte sedimentation rate (ESR) (65 mm). Chest X-ray and abdominal ultrasonography were normal. Mantoux test was negative. Fine-needle aspiration cytology from the subcutaneous nodule in the gluteal area from the lesion in the buttock predominantly showed histiocytes with plenty of plasma cells and lymphocytes. Few of the histiocytes showed emperipolesis.
Histopathological examination was done after the excision of the subcutaneous nodule over the left anterior thigh which showed an unencapsulated mass consisting of numerous lymphoid follicles. Surrounding areas showed sheets of histiocytes having bland nuclei and abundant foamy cytoplasm along with fibrocollagenous tissue and vascular fragments. Occasional histiocytes showed the presence of intact lymphocytes and plasma cells in its cytoplasm suggesting emperipolesis [Figure 2]. The presence of numerous foci of plasma cell aggregates was also noted. Periodic acid-Schiff stain, Gram stain, and Fite stain were all negative. Immunohistochemistry studies could not be done due to affordability issues. Thus, taking into consideration, the cutaneous, systemic, laboratory, and histopathological findings, a diagnosis of cutaneous RDD was made.

The patient was started on oral prednisolone (0.5 mg/kg) with a significant decrease in the size of the lesions after one month. Thereafter, the patient was lost to follow-up.
| Discussion|| |
RDD was first described by Destombes in 1965 but was first recognized as a distinct clinicopathological entity by Juan Rosai and Ronald F. Dorfman in 1969. It is a self-limiting, non-Langerhans cell histiocytosis of unknown etiology occurring in any age group with a predilection for young adult males, presenting with painless massive cervical lymphadenopathy that is mostly bilateral. Although constitutional symptoms and laboratory abnormalities such as leucocytosis, raised ESR, and polyclonal hypergammaglobulinemia are common in systemic RDD, they may not be present in purely cutaneous RDD.
Cutaneous RDD is an extremely rare entity and unlike classic RDD, it has a predilection for the age group above 40 years and is more common in females. It is extremely rare in children with only a few cases being reported, previously as per our literature search.
Cutaneous RDD may present as asymptomatic yellowish red or erythematous or brownish papules, plaques, nodules, or a combination of these. The most common site involved is the face, while trunk, upper, and lower extremities may also be involved. Lesions may be solitary or multiple; may occasionally occur in clusters or with satellite lesions. Kong et al. described three main types of skin lesions, i.e., papulonodular type (79.5%), indurated plaque type (12.8%), and tumor type (7.7%). Cutaneous RDD resembling acne, psoriasis, and eruptive xanthoma has been reported., Few cases are known to have presented with subcutaneous nodules.,
Histopathologically, there is a dense histiocytic infiltrate with plasma cells and lymphocytes. “Rosai-Dorfman cells” are characteristic, which are large foamy polygonal histiocytes with pale eosinophilic cytoplasm and having vesicular nuclei with feathery or indistinct cell borders. They exhibit the phenomenon of emperipolesis which represents the presence of intact lymphocytes, plasma cells or rarely neutrophils, and red blood cells engulfed within the histiocytes. These histiocytes are strongly reactive for S-100 protein and variably positive for CD68 but are negative for CD1a. Lymphoid follicules with germinal centers may occur in cutaneous RDD as in our case.
Although the exact etiology of this disease remains unknown, literature suggests an immune dysfunction to an antigen or infectious agents such as human herpesvirus 6, Epstein–Barr virus, parvovirus B19, herpes simplex virus, Brucella More Details, Klebsiella rhinoscleromatis, and Nocardia; on the basis of temporal association and reactive serology in some affected patients. Association with other diseases such as bilateral uveitis, antinuclear antibody positive lupus erythematosus, rheumatoid arthritis, hypothyroidism, lymphoma, and HIV infection has been noted.
The prognosis of cutaneous RDD is good and often follows a benign course with a strong possibility of spontaneous remission occurring over months to years. Single and isolated skin lesions can be excised and generalized lesions may require systemic treatment. Cryotherapy, local radiation, topical and intralesional corticosteroids can be used for limited number of lesions. Systemic corticosteroids, thalidomide, dapsone, isotretinoin, and imatinib are other treatment modalities with varying response.
The fact that our case presented solely with multifocal subcutaneous nodules and that too in a 6-year-old child complicated the diagnosis of cutaneous RDD. A rare clinical presentation at an age much earlier than previously reported is what makes our case worth reporting. Thus, it is important to consider cutaneous RDD as a differential diagnosis in a child presenting with subcutaneous nodules. A high index of suspicion along with histopathology and immunohistochemistry is thereby very essential for the early diagnosis of this disease as it may present with nonspecific and a wide array of cutaneous lesions and in any age group.
