Churg-Strauss syndrome (CSS) is a rare, potentially lethal systemic vasculitis characterized by necrotizing arteritis, eosinophil infiltration of the tissues, and extravascular granulomas.1 Ocular involvement includes orbital inflammation, scleritis or episcleritis, peripheral ulcerative keratitis, uveitis, anterior ischemic optic neuropathy, retinal artery and vein occlusions, choroidal ischemia, and oculomotor nerve palsies. Conjunctival involvement is rare and can present as nonspecific conjunctivitis, inflammatory thickening of the conjunctiva with or without amyloidosis, or conjunctival nodule with inflammation.25 We describe a patient with clinically inactive CSS who developed multiple bilateral conjunctival nodules.

Report of a Case

In June 2011, a 38-year-old woman had ocular irritation and foreign body sensation in both eyes (OD > OS) for 2 weeks. She denied ocular pain, diplopia, or a change in visual acuity. Since December 2010, she had attacks of asthma, recurrent sinusitis, episodes of upper gastric pain, and skin rash. A thorough workup revealed granulomas of the lung associated with tissue eosinophilia, peripheral eosinophilia, increased total IgE level, and positive findings for perinuclear antineutrophil cytoplasmic antibodies. Thus, the patient fulfilled the criteria of the American College of Rheumatology to be diagnosed as having CSS with 4 of 6 of the following signs present: asthma, eosinophilia greater than 10% on differential white blood cell count, tissue eosinophilia, nonfixed pulmonary infiltrates, paranasal sinus abnormalities, and mononeuropathy or polyneuropathy. Systemic therapy with corticosteroids and azathioprine was initiated.

On examination in June 2011, visual acuity was 20/20 OU and intraocular pressures were normal. Slitlamp examination disclosed a white and quiet conjunctiva with multiple (9 in the right eye, 4 in the left eye) yellowish subconjunctival nodules (0.5-2 mm) without feeder vessels in the superior bulbar conjunctiva (Figure 1) associated with superficial punctate keratopathy in the right eye. Treatment with intense topical corticosteroids together with ocular lubrication was instituted but did not resolve the conjunctival lesions and/or improve the ocular surface. Therefore, after informed consent was obtained, an excisional biopsy of the largest bulbar nodules in the right eye was performed under local anesthesia.

On microscopy, an intense inflammatory response was obvious in the entire conjunctival stroma with multiple granulomas composed of CD3+ T lymphocytes, CD20+ B lymphocytes, CD68+ macrophages, histiocytes, giant cells, and multiple eosinophils surrounding a center of tissue necrosis (Figure 2). The inflammation was particularly intense around vessels, especially arteries, and associated with vascular occlusion. The perivascular infiltrate mainly consisted of CD3+ T lymphocytes and CD20+ B lymphocytes as well as histiocytes and giant cells (Figure 2).

Gomori methenamine silver, periodic acid–Schiff, and Ziehl-Neelsen stains excluded fungi and mycobacteria. Histopathologic analysis of the conjunctival nodules confirmed the presence of multiple eosinophilic perivascular granulomas consistent with CSS.

Comment

Our patient with systemically inactive CSS developed multiple conjunctival eosinophilic granulomas. This clinical manifestation is extremely rare and, to our knowledge, has never been described in this form. Shields et al2 treated a 64-year-old man with CSS and progressive inflammatory thickening of the bulbar and palpebral conjunctiva in 1 eye that resolved with systemic corticosteroids and cyclophosphamide. Margolis et al5 described a 30-year-old woman with CSS who had 1 well-demarcated conjunctival nodule with mild focal inflammation. Histologic analysis of both cases confirmed the presence of necrotizing eosinophilic granuloma, but a pathognomonic vasculitis was not observed.2,5 The findings in our patient with CSS are also distinct from conjunctival involvement in Wegener granulomatosis, where inflammation is mainly confined to the palpebral conjunctiva and tarsus followed by fibrovascular proliferation and scarring.6 Our case is special in some respects: multiple granulomas developed bilaterally in the clinically completely uninflamed conjunctiva of a patient with CSS under apparently successful systemic immunosuppressive therapy. Moreover, the excised conjunctival tissue showed a clear-cut vasculitis, which, according to Takanashi et al,7 is quite uncommon for the orbital inflammatory pseudotumor type of CSS where conjunctival lesions are included in contrast to the ischemic type. Signs of eosinophilic tissue infiltration and granuloma formation only rarely coincide with signs of vasculitis in ocular CSS.7 Thus, the development of conjunctival granulomas in successfully treated CSS and the demonstration of vasculitis on biopsy may be early signs of activation and should prompt a careful clinical follow-up.
