Granulomatosis with polyangiitis-associated sclerokeratitis in a case of ocular adnexal B-cell lymphoma.

We describe the first reported case of granulomatosis polyangiitis (GPA)-associated sclerokeratitis in a patient with treated ocular adnexal lymphoma (OAL). The patient presented with pain and decreased vision in the left eye over several weeks. Past medical history was significant for recent bilateral relapsing OAL that was treated successfully with radiotherapy. Examination of the eyes revealed sectoral scleritis and peripheral ulcerative keratitis. Magnetic resonance imaging (MRI) of the orbits excluded recurrence of OAL and serum antineutrophil cytoplasmic autoantibody (ANCA) titres confirmed the diagnosis of GPA. Disease was poorly responsive to systemic steroids, azathioprine and rituximab. Ultimately, resolution was achieved with successive subconjunctival dexamethasone and subconjunctival triamcinolone injections. This case highlights the need to consider ocular inflammation in patients with a history of malignant hemopathies.
