Conjunctival Follicular Lymphoma after Treatment for Invasive Squamous Cell Carcinoma

BACKGROUNDS/AIMS The authors describe the case of a 79-year-old Caucasian woman who presented an ocular adnexal lesion as the first clinical manifestation of a systemic follicular lymphoma, highlighting the clinicopathological features of this rare entity and its potential to be misdiagnosed as marginal zone lymphoma of the mucosa-associated lymphoid tissue. METHODS Conjunctival impression cytology was performed for a rapid initial diagnosis of lymphoma, and subsequent histopathological and immunohistochemical studies were carried out for its confirmation and to identify the best therapeutic regimen. RESULTS After the initial presentation and diagnosis, she was submitted to complete clinical evaluation; confluent retroperitoneal lymphadenopathy was detected through abdominal computed tomography, characterizing clinical stage III. CONCLUSION Awareness of this lymphoma is important when making a diagnosis of ocular adnexal lymphoid neoplasms for its appropriate evaluation and management.
