Lymphoid Proliferation in Eyelid: A Primary Follicular Lymphoma Case.

Ocular adnexal lymphoma (OAL) constitutes 8% of all extranodal lymphomas, being rare in the eyelids (5-20%). The objective was to report a case of eyelid follicular lymphoma in a young adult woman. A 35-year-old female with swelling in left lower eyelid with development for 2 months. The visual acuity was 20/20 in both eyes, the tumor mass was 3 cm wide and 1.5 cm long. The contrast-enhanced computed tomography showed a soft-tissue injury in the left lower eyelid but had no signs of local spread according to description. Grade 2 follicular lymphoma was diagnosed by biopsy. Oncological evaluation assessed positron emission tomography scan and bone marrow aspiration with negative results for systemic spread of disease. Patient started radiotherapy. This case highlights that young patients may present painless swelling lesions that may be largely underdiagnosed and should take into consideration some oncological pathologies.
