Primary Cutaneous Peripheral T-Cell Lymphoma of the Hand: Case Report of a Rare Diagnosis and Review of the Literature
Abstract Purpose Primary cutaneous T-cell lymphoma (CTCL) is a rare diagnosis, and the subset primary cutaneous peripheral T-cell lymphoma (pcPTL) is even more uncommon. Both CTCLs and pcPTLs typically occur in the head and neck. The authors aim to evaluate the literature for reports of presentation in the hand. Materials and Methods A case report of a 77-year-old man with pcPTL of the hand is presented. Oncologic workup revealed an independent diagnosis of medullary thyroid carcinoma. A review of the literature was performed using the following search terms in the PubMed database: primary, cutaneous, T-cell lymphoma, peripheral presentation, and hand. One case of pcPTL in the hand was identified and included in this study. Results One case report in the literature was identified describing a 78-year-old man with a 1-year history of a progressive hand lesion. Biopsy revealed pcPTL. Conclusion This report presents a rare presentation of pcPTL in the hand, reviews the current literature, and provides insight into management. Prompt biopsy of any unresolving lesion of the hand is crucial to expedite diagnosis and treatment of otherwise difficult to diagnose pathologies. Increased awareness of rare malignancies is important to avoid delay in patient care and to improve outcomes.
