ABSTRACT Castleman disease is a non-neoplastic cause of lymphadenopathy, first described in 1956 by Dr. Benjamin Castleman. Orbital involvement in Castleman disease is extremely rare. We report a case of bilateral orbital Castleman disease in a 48-year-old Asian male who presented with bilateral inferior dystopia. MRI revealed bilateral extraconal superior orbital mass. Histopathology and immunohistochemistry of the mass revealed features of Castleman disease of hyaline vascular type. Castleman disease should be a differential in suspected idiopathic orbital inflammatory disease and lymphoproliferative disorders. Keywords: Castleman disease, orbit, proptosis

of Hg in the right and left eye respectively. Fundus examination showed bilateral choroidal folds with normal optic discs. Magnetic Resonance Imaging (MRI) of the orbits revealed bilateral superior extraconal lobulated mass lesion, suggestive of lymphoma (Figure 2). The patient underwent incisional biopsy through lid crease approach in the right eye. Histopathological examination revealed a well-capsulated lesion composed of lymphoid follicles with germinal centers with vascular proliferation and hyalinization. Some follicular dendritic cells were also seen (Figure 3a and b). Immunohistochemistry was positive for CD3 and CD 43 (interfollicles), CD20 & CD79a (follicles), CD21 and CD 23 (dendritic cells). Histopathology and immunohistochemistry corroborated the diagnosis of Castleman disease (CD). Patient was advised about complete surgical removal of the orbital masses, along with consultation with hemato-oncologist for systemic evaluation to rule out multicentric disease. However, the patient was from a neighboring country, and he had to leave due to expiry of his visa. He was asked to renew his visa and return for further management as soon as possible.

Castleman disease (CD) is a non-neoplastic cause of lymphadenopathy. It was first described by Dr Benjamin Castleman in 1956.1 Since then, only eleven cases of orbital Castleman disease have been reported in the literature.2 Clinically, the disease can either be unicentric or multicentric with systemic involvement. We report a rare case of Castleman disease involving both orbits.

CASE REPORT A 48-year-old Asian male from the Indian subcontinent presented with painless, progressive mass lesions over the eyeballs for the past 3 years. There were no systemic complaints. On examination, there was bilateral gross proptosis with inferior dystopia (Figure 1). Best corrected visual acuity in both the eyes was 20/80 (Jaeger). Color vision was grossly abnormal in both the eyes and pupils were sluggish. Ocular movements were limited in all direction of gaze. Bilateral well-circumscribed, firm-to-hard, superior orbital masses were seen. There was no lymphadenopathy. Intraocular pressure was 22 and 24 mm

Castleman disease is a non-neoplastic abnormal follicular proliferation of uncertain pathogenesis.4 It is also known as angiofollicular or giant lymph node hyperplasia. Clinically it has two variants, a localized one with a good prognosis, and which is

curable with complete surgical resection. And a multicentric variant with widespread lymphadenopathy and organomegaly, presenting with systemic symptoms like fever, chills, and night sweats. This variant usually has a poorer prognosis.5 Histopathologically Castleman disease has been classified into three subtypes. The hyaline vascular, plasma cell, and mixed cell type.4 Hyaline vascular Castleman disease characteristically consists of atrophic hyalinized follicular centre with onion skin arrangement of small lymphocytes and one or more penetrating blood vessels conferring a ‘‘lollipop on stick’’ appearance. The plasma cell type is characterized by hyperplastic germinal centers with sheets of plasma cells in the interfollicular areas. Paracortical hypervasuclarity and onion skin mantle zone of lymphocytes are absent.5 The mixed cell type has features of both.3 Of the previous 11 cases published in literature till date, the most common type has been reported to be of hyaline vascular type (7 cases); one each of plasma cell and mixed cell type; and in two, histopathological typing was not available.2

Castleman Disease 317 Recently, a new classification has been proposed by some authors which divides Castleman disease into four subtypes, namely, hyaline vascular, plasma cell, HHV-8 associated CD and a multicentric CD- not otherwise specified (NOS).6 The pathogenesis of Castleman disease is unclear. Aberrant production of IL – 6 secondary to stimulation by HHV – 8 or unidentified exogenous and endogenous factors leading to plasma cell proliferation and their resistance to apoptosis has been considered as a possible mechanism in multicentric CD.7,8 Castleman disease rarely involves sites lacking in lymphatic tissue such as the brain and orbit. Snead et al. had reported the first histopathologically proven case of orbital Castleman disease. The authors had also noted that it is impossible to differentiate this condition from orbital lymphoma without biopsy and histopathological examination.9 Orbital Castleman disease can also mimic idiopathic orbital inflammatory disease (IOID).10 Unlike unicentric involvement, where complete surgical excision is curative, there is no standard treatment protocol for multicentric disease. Various treatment modalities like surgical resection, steroids, chemotherapy, radiotherapy, immunotherapy (interferon a, all Trans retinoic acid, thalidomide), anti-viral therapy, and monoclonal antibodies have been tried with variable results.7 Ide et al. had reported a case of bilateral multicentric Castleman disease treated successfully with Rituximab.11 Orbital involvement in Castleman disease is relatively rare. To the authors’ knowledge, five cases of bilateral orbital Castleman disease have been reported in the literature till date (including the present study) (Table 1). The first case of bilateral orbital Castleman diseases was reported by Kurokawa et al. in 1999.12 We find that bilateral orbital involvement is seen more commonly in elderly males, usually of hyaline vascular type. They can present with lacrimal gland enlargement, peri-optic swelling, or orbital mass lesions. Multicentric involvement is a definite possibility and must be ruled out by systemic examination and appropriate investigations in this group of patients. In conclusion, Castleman disease is an

important differential diagnosis to be considered among other orbital afflictions like IOID, IGG4 related sclerosing disease and lymphoproliferative disorders.
