Orbital and adnexal Rosai-Dorfman disease

Isolated bilateral orbital and paranasal Rosai-Dorfman disease affecting two brothers: a case report and a systematic literature review

A systematic literature review revealed 88 Rosai-Dorfman Disease (RDD) cases affecting the orbit. We present a review of the literature on orbital RDD in addition to two brothers with isolated bilateral extra-nodal orbital RDD cases associated with G-6PD deficiency. The disease manifested as asymmetric extensive orbital and paranasal sinus infiltration, with orbital bone destruction. Orbital mass debulking and steroids improved the condition in both patients. This is the most extensive case series of orbital RDD reported, including clinical manifestation, imaging, pathologic results, management, and outcome. Vigilant follow-up is essential to monitor for potential malignant transformation, systemic manifestations, potential vision loss, or life-threatening recurrences.

Rosai-Dorfman disease manifesting as epibulbar and orbital tumor: A case report and literature review

RATIONALE

Rosai-Dorfman disease (RDD) is a rare nonmalignant cell histiocytosis. Here, we report a rare, unusual clinical presentation of epibulbar and orbital tumor as a manifestation of RDD. We also review the literatures on clinical cases of orbital RDD.

PATIENT CONCERNS

A 44-year-old Chinese male was admitted with a 3-month history of eye redness, subconjunctival mass, and diplopia.

DIAGNOSIS

An initial diagnosis of epibulbar and orbital tumor was made according to the clinical symptoms, signs, and pre-operative contrast-enhanced computerized tomography results.

INTERVENTIONS

The mass was completely resected and pathology confirmed the RDD diagnosis. The patient received steroids after surgery.

OUTCOMES

The patient recovered well on 18-month follow-up.

CONCLUSION

This appears to be the first report of RDD manifesting as epibulbar and orbital tumor. Pre-operative diagnosis of RDD remains challenging. When the lesion causes diplopia, surgical resection is the most effective treatment.

Orbital presentation of Rosai-Dorfman disease

OBJECTIVE

To report a case of orbital mass and proptosis, diagnosed as Rosai-Dorfman disease (RDD).

METHODS

Clinical case report based on the review of clinical charts, radiological images, and histopathology.

RESULTS

A 42-year-old male with orbital mass and proptosis of the right eye. A surgical biopsy was performed, and the diagnosis of RDD was established using microscopy and immunohistochemistry. Definitive management included open tumour cytoreduction, with good response.

DISCUSSION

The RDD is a rare, benign, proliferative condition of unknown origin. It rarely affects the cranial cavities, with the orbital presentation being very unusual. Diagnostic confirmation is essential for the best surgical management.

Ophthalmic Findings of Rosai-Dorfman Disease

PURPOSE

To describe the ophthalmic, pathologic, and BRAF V600E mutation status of Rosai-Dorfman disease (RDD).

DESIGN

Retrospective case series.

METHODS

A retrospective review of all cases of RDD seen at Mayo Clinic from 1992 to 2016 identified patients with ophthalmic manifestations (n = 8). Immunostain for BRAF and molecular studies for BRAF V600E mutation were performed on cases with tissue available.

RESULTS

Of 76 patients with RDD, 15 had eye examinations; of those, 8 (5 female and 3 male) had ophthalmic manifestations. In RDD patients with ophthalmic manifestations compared to RDD patients without ophthalmic manifestations, the respective median (range) age in years was 42 (15-70) and 56 (32-79) (P = .13) and median (range) logMAR visual acuity was 0.048 (0.000-1.824) and 0.000 (-0.124 to 0.301) (P = .19). Of the 8 patients with ophthalmic manifestations, 4 had ocular involvement and 4 had orbital masses. Patients with ocular involvement had multiorgan disease including tracheal, aortic, renal, skeletal, and soft tissue lesions (n = 4). Patients with orbital masses had no systemic involvement (n = 2), skeletal involvement only (n = 1), or multiorgan disease (n = 1). BRAF immunostaining and molecular studies were negative in all available specimens (n = 6).

CONCLUSIONS

In this series of patients with ophthalmic manifestations of RDD, those with ocular involvement had multiorgan disease while those with orbital masses had more limited systemic disease. Patients with ophthalmic manifestations tended to be younger and have worse visual acuity. Additionally, ophthalmic RDD does not seem to be associated with BRAF mutation.

Isolated unilateral eyelid Rosai-Dorfman disease

Isolated eyelid Rosai–Dorfman disease without orbital disease or systemic involvement is very rare and needs a high degree of suspicion. In this report, we describe a 16-year-old boy who presented with isolated eyelid Rosai–Dorfman disease involving the right upper eyelid. The lesion was treated by surgical debulking followed by intralesional steroid injection for the residual lesion. The child did well with no evidence of recurrence of the lesion at 1-year follow-up.

[Rationale for a diagnostic approach in non-Graves' orbital inflammation--Report of 61 patients]

INTRODUCTION

Orbital inflammatory syndromes include a wide variety of inflammatory intraorbital processes which are very different in terms of clinical presentation and prognosis. We currently prefer to differentiate so-called "specific" inflammations, for which an etiology is able to be identified, from idiopathic orbital inflammatory syndromes (IOIS), for which the etiology remains unknown and the histology is nonspecific.

PURPOSE

To propose an efficient diagnostic approach for clinicians managing patients with non-Graves' orbital inflammations.

MATERIALS AND METHODS

This is a retrospective and prospective study concerning 61 patients managed by the medical team for non-Graves' orbital inflammations between May, 1999 and May, 2013 in the ophthalmology departments of Nice and Limoges university hospitals in France. Seventeen specific inflammations, 19 orbital lymphomas and 25 idiopathic orbital inflammatory syndromes were included. Patients were divided into two groups. Thirty-six patients (group 1) underwent primary biopsy, while for the other 25 (group 2), therapy was begun empirically without biopsy. We could therefore compare both approaches in terms of diagnostic efficiency and time until identification of a specific etiology.

RESULTS

Our statistical results show that an approach without primary biopsy leads to a number of specific diagnoses statistically much lower than that obtained by the approach with primary biopsy. Also, the risk of missing a specific inflammation (with as a consequence an inappropriate treatment and a risk of functional sequelae as well as a fatal risk of missing a lymphoproliferative pathology) is very clearly higher in the case of not performing primary biopsy. Finally, the average time elapsed between the initial consultation with the ophthalmologist and a specific diagnosis was one month in the case of the first approach, while this delay was almost three times higher with the second approach, with a mean of 2.91 months (P<0.01).

DISCUSSION

Our study shows that biopsy should be the mainstay of diagnostic management. A trial of empiric treatment is only performed first in myositis or in locations where biopsy could jeopardize functional prognosis. It should only be done after biopsy in all other cases. Of course, in all cases of relapse or recurrence after treatment, biopsy should be performed or repeated.

CONCLUSION

The diagnostic work-up of a patient with an orbital inflammatory process must of course include blood testing and orbital imaging, but also a systematic primary biopsy for histological examination in the vast majority of cases. It must be repeated at least in the case of any doubt about the diagnosis or in the case of any recurrence or resistance to treatment.

Orbital Rosai-Dorfman disease: a literature review

INTRODUCTION

Rosai-Dorfman disease (RDD) is a rare histiocytic proliferative disorder with a predilection for the head and neck. Isolated orbital involvement without systemic clinical features is very uncommon.

BACKGROUND

Classic histopathologic features include phagocytized but intact lymphocytes within large histiocytes; a conditioned termed emperipolesis. Immunohistochemical stains are strongly positive for S-100 and CD68 but negative for CD1a in most cases. Orbital cases are often amenable to complete surgical resection.

CONCLUSION

RDD should be considered in the differential diagnosis of a young patient in good health who presents with a marked but benign enlargement of an orbital mass. A review of the literature regarding this disease entity and its orbital manifestations is discussed.

Rosai-Dorfman disease presenting as choroidal melanoma: a case report and review of the literature

BACKGROUND

Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare non-malignant proliferation of histiocytes of unknown aetiology. It was first recognised as a distinct clinicopathologic entity in 1969, and is classified as an idiopathic non-Langerhans cell histiocytosis. The disease process is usually self-limiting and often involves lymph nodes, but extranodal involvement is well-described and any anatomic site can be involved.

METHODS

We describe a unique case of a 40-year-old male who presented with a fundus mass diagnosed clinically as choroidal melanoma. The tumour showed rapid growth. The patient developed a total retinal detachment and underwent enucleation. The globe contained a choroidal tumour with histologic and immunophenotypic features characteristic of RDD. The literature of ocular Rosai-Dorfman disease was reviewed.

RESULTS

This is the first case in the English literature of intraocular choroidal RDD, mimicking choroidal melanoma.

CONCLUSIONS

Rosai-Dorfman disease can present as a mass-producing lesion in the choroid and may mimic other choroidal tumours. The case emphasises the need to consider diagnostic biopsy prior to definitive treatment of choroidal tumours.

Reactive histiocytosis of the orbit and posterior segment in a dog

We present a case of reactive histiocytic disease involving the orbit, optic nerve, retina, and choroid in a Border Collie dog initially presenting for vision loss. Long-term partial return of vision has been achieved with systemic immunosuppression. Anterior segment and ocular surface manifestations of reactive histiocytic disease in dogs are relatively common. Posterior segment and orbital involvement, however, are minimally documented in the existing literature. To the authors' knowledge, this is the first report of disease confined to the orbit and posterior segment as well as the first report of vision loss as a presenting complaint for reactive histiocytic disease. Clinical, magnetic resonance imaging, cytologic, and histopathologic findings are reviewed.

Orbital Rosai-Dorfman disease with subperiosteal bone involvement mimicking eosinophilic granuloma

The presentation of RDD as an anterior subperiosteal orbital mass with bone involvement has, to the authors' knowledge, not been previously reported. We describe a case of Rosai-Dorfman disease (RDD) presenting as an anterior superolateral subperiosteal orbital mass with erosion of overlying bone mimicking eosinophilic granuloma. It was debulked using endoscopic-guided curettage and the patient was given both local and systemic corticosteroids. Careful histological analysis revealed the diagnosis of RDD and the patient remains asymptomatic and recurrence free at 16 months follow-up. Involvement of the pituitary gland, a recognized yet unusual finding in this condition was also noted. RDD should be considered in the differential diagnosis of a soft tissue mass of the superolateral orbit.

Primary intracerebral Rosai-Dorfman disease

Sinus histiocytosis with massive lymphadenopathy (SHML), also known as Rosai-Dorfman disease (RDD), is an idiopathic histiocytic disorder of lymph nodes and extranodal sites. Central nervous system (CNS) manifestations, particularly in the absence of nodal disease, are rare. Intracranial RDD clinically and radiologically resembles meningioma, and histologic examination is essential for a definitive diagnosis. We report four patients with RDD primary to the CNS without evidence of other sites of involvement, review the literature, and discuss the clinical manifestations, pathology, treatment and outcome.
