Atypical Presentation of Isolated Peripheral T-Cell Lymphoma in the Hand: Case Report

Peripheral T-cell lymphoma is a rare malignancy that characteristically demonstrates generalized lymphadenopathy and extranodal involvement. We describe an atypical case of peripheral T-cell lymphoma manifesting as isolated hand swelling without evidence of nodal disease or systemic symptoms. This report emphasizes the highly variable clinical presentation of T-cell lymphomas and the importance of expeditious incisional biopsy in the setting of an undiagnosed hand mass.
