Abstract

Title: Ocular Marginal Zone B Cell Lymphoma Of A Mucosa-Associated Lymphoid Tissue (MALT) Masquerading As Chalazion: A Case Report And Review Of Literature

Background: To report a case of Ocular Marginal Zone B Cell Lymphoma Of A MALT presenting as chalazion.

Method: Case report

Result: A 57-year-old Chinese gentleman, known to have Diabetic Mellitus and HBV positive presented with painless right lower lid swelling and conjunctiva injection for 3 months duration. A diagnosis of chalazion was made and incision and curettage (I&C) performed by a general ophthalmologist. The swelling worsened and spread to the whole lower lid. Magnetic resonance imaging showed a lesion involving right periorbital region limited to anterior of the orbital septum that was hypointense on T1, and hyperintense on T2. Histopathology of the conjunctiva biopsy showed features of low-grade Non-Hodgkin B-cell lymphoma and immunohistochemistry report suggestive of marginal zone lymphoma.

Conclusion: This case showed a rare presentation of Ocular Adnexal Lymphoma (OAL) manifested as chalazion
