Syphilis, a sexually transmitted disease caused by Treponema pallidum, manifests with a broad spectrum of clinical presentations that usually involves skin. Nodular secondary syphilis occurs rarely, and mostly manifests as disseminated papulonodules or plaques over the trunk and limbs. We report an extremely rare case of nodular secondary syphilis that primarily presented with multiple nodules on the scalp, resembling Rosai-Dorfman disease or cutaneous malignant metastasis. Immunohistochemistry confirmed T...

Tumors derived from histiocytic and dendritic cells encompass a large and heterogeneous group of neoplastic and reactive conditions, and their diagnosis is challenging both for pathologists and clinicians. Diagnosis is based on morphological and phenotypical findings, but hybrid features are not uncommon. Furthermore, recent studies uncovered the molecular mechanisms driving some of these tumors, improving diagnostic adequacy, and providing the basis for effective therapeutic breakthroughs.Sixty-seven cases were submitted to the accessory cell and histiocytic neoplasms session at the European Association of Haematopathology/Society for Hematopathology workshop 2016 held in Basel, Switzerland...

Rosai-Dorfman disease is a histiocytic disorder with a poorly defined pathogenesis. Recent molecular studies have revealed recurrent mutations involving genes in the MAPK/ERK pathway in Langerhans cell histiocytosis and Erdheim-Chester disease. However, cases of Rosai-Dorfman disease have rarely been assessed. We performed next-generation sequencing to assess 134 genes on 21 cases of Rosai-Dorfman disease, including 13 women and 8 men with a median age of 43 years (range, 3-82). In all, 13 had extranodal, 5 had nodal, and 3 had coexistent nodal and extranodal disease...

Rosai-Dorfman disease (RDD) is a rare histiocytosis typically with bilateral painless cervical lymphadenopathy. Laboratory data are nonspecific, and the presence of emperipolesis in large foamy S-100+ CD1a- histiocytes is the prominent histologic feature. The pathogenesis of RDD still remains elusive. According to published studies, we propose that RDD cells might represent intermediate recruiting monocytes with differentiation blockade. Both disturbance of homoeostasis and inherent genomic alterations could contribute to initiation of the disorder through signal transduction...

Rosai-Dorfman Disease (RDD) is a rare disease that normally presents with bilateral cervical lymph node enlargement. Systemic symptoms of fever and weight loss may be present but patients are usually asymptomatic. This benign disease tends to regress on its own without treatment but there have been cases that required treatment with steroids or chemotherapeutic regimes. Extranodal disease in the breast is extremely rare, with only three cases identified in the male breast. The patient in this study presented with an asymptomatic right breast lump identified incidentally...

BACKGROUND: A proportion of cases of Rosai-Dorfman disease exhibit some histological features consistent with IgG4-related disease (IgG4RD). Several investigators have discussed whether Rosai-Dorfman disease belongs to the spectrum of IgG4RD or is concurrent with it by coincidence. OBJECTIVE: To elucidate the relationship between the two diseases, we report key features, including IgG4 and amyloid levels, of four cases of Rosai-Dorfman disease in the breast. METHODS: The histological features of the four cases were analyzed and the numbers of IgG4+ plasma cells and IgG4/IgG ratios were evaluated...

Rosai-Dorfman disease (RDD) is a rare condition similar to lymphomas, presenting with cervical lymphadenopathy in young adults. Extra-nodal involvement is relatively common but involvement of the central nervous system (CNS) is rare. Cranial RDD presents with symptoms of raised intracranial pressure, focal or generalised seizures, while spinal RDD presents with pain, peripheral neurological deficits and radiculopathy. In contrast to other similar neoplastic or degenerative conditions affecting the CNS, RDD is a benign, non-infective, granulomatous disorder...

Rosai-Dorfman disease is a rare systemic proliferative disorder of histiocytes, which mainly manifests as lymphadenopathy but also often involves extranodal tissues. Rosai-Dorfman disease was often self-limited. We hereby report a case of Rosai-Dorfman disease involving both the lymph nodes and the lungs, which was spontaneously resolved on FDG PET/CT.

Rosai-Dorfman disease (also known as sinus histiocytosis with massive lymphadenopathy) is a rare benign proliferative disorder of histiocytes that typically involves the lymph nodes and can also involve extranodal sites. Rosai-Dorfman disease confined to the breast is extremely rare, but important to recognize as it can mimic malignancy. We present the case of a 63-year-old woman who presented with a palpable breast lump that was highly suspicious for malignancy based on mammogram and ultrasound appearance...

Yellowish papules, nodules, or plaques, namely "xanthomatous" lesions, may be seen on the eyelids in the course of various disorders. The prototype is "xanthelasma palpebrarum" (XP) that is localized only to the eyelids and may be associated with hyperlipidemia. On the other hand, different types of normolipemic disorders may also cause xanthomatous eyelid lesions. Among these, Langerhans cell histiocytosis, diffuse normolipemic xanthoma, and non-Langerhans cell histiocytoses (papular xanthoma, juvenile xanthogranuloma, xanthoma disseminatum, adult-onset xanthogranuloma, adult-onset asthma and periocular xanthogranuloma, necrobiotic xanthogranuloma, Erdheim-Chester disease, Rosai-Dorfman disease, and reticulohistiocytosis) can be listed...

Rosai-Dorfman disease, or sinus histiocytosis with massive lymphadenopathy, is a rare multisystemic disorder that was first reported by Rosai and Dorfman in 1969. It is a distinct histioproliferative disorder due to overproduction of histiocytes, which accumulate in lymph nodes. The cardiac involvement of this disease is extremely rare, and until now, only 18 cases have been reported. We report the case of a 53-year-old woman with right atrial mass mimicking myxoma, which the histopathologic evaluation revealed to be Rosai-Dorfman disease of the right atrium...

We herein report a case of Rosai-Dorfman disease (RDD) overlapping with IgG4-related disease (IgG4-RD), which presented as diffuse interstitial lung disease with a perilymphatic pattern, followed by submandibular gland and eyelid swelling. The pathological findings of the submandibular gland biopsy specimen were indicative of IgG4-RD alone. We diagnosed the patient with RDD with overlapping IgG4-RD. However, the optimal method for differentiating between these two entities is still controversial. It is important that clinicians are aware that RDD should be included in the differential diagnoses of diffuse interstitial lung disease with a perilymphatic pattern and that RDD can overlap with IgG4-RD...

Primary histiocytic tumors of the CNS are rare. The current WHO classification (2016) included 5 entities: Langerhans cell histiocytosis (LCH), Erdheim-Chester disease (ECD), Rosai-Dorfman disease (RDD), juvenile xanthogranuloma (JXG), and histiocytic sarcoma (HS) (1). The diagnosis usually is made based on the tumor differentiation as to the counterpart in normal histiocyte development. This article is protected by copyright. All rights reserved.
