A clinicopathologic study of sinus histiocytosis with massive lymphadenopathy mimicking an optic nerve tumor

Ophthalmic Rosai-Dorfman disease: a multi-centre comprehensive study

Background

To provide basic demographic information and clinicopathologic features of ophthalmic Rosai–Dorfman disease (RDD) with a literature review.

Methods

A multi-centre retrospective case series reviewing all patients with histopathologically confirmed ophthalmic RDD at three tertiary eye care centres between January 1993 and December 2018.

Results

Eleven eyes of eight patients with histopathologically confirmed ophthalmic RDD were included, with equal numbers of males and females. The median age was 40.25 years (range: 26.6–72.4). Two patients had familial RDD. The orbit was the most commonly involved site (90.9% eyes). One patient (one eye) presented with a scleral nodule, anterior uveitis and cystoid macular oedema. Visual acuity ranged from 20/25 to light perception. Six patients had an extra-nodal ophthalmic disease, and the remaining two had an associated submandibular lymphadenopathy (nodal RDD).

Conclusions

Ophthalmic RDD can be the only manifestation of this systemic disease, with the orbit being the most commonly involved site, exhibiting bone destruction, intracranial and/or sinus involvement and variable degree of visual loss. Ophthalmic familial RDD represent a severe form with a malignant course. Steroid monotherapy may be inadequate to control orbital RDD; thus, combined treatment is usually necessary. A comprehensive approach to assessment and management is recommended.

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.

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.
