title: Conjunctival lymphoma can be detected by FDG PET.
abstract: Four consecutive patients presented with extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the conjunctiva. After the initial resection, long-term follow-up without additional therapy showed the clinical relapse. Fluorodeoxyglucose positron emission tomography fused with computed tomography (PET/CT) showed abnormal uptake in the conjunctival relapsed lesions, which were, on reresection, again proven as MALT lymphoma. Small and thin lesions of MALT lymphoma in the conjunctiva can be detected by fluorodeoxyglucose PET/CT. The resolution of PET/CT, delineated in this study, could be applied to the other areas of the body to achieve more accurate staging of lymphoma.
