An unusual case of primary cutaneous lymphoma presenting in the upper extremity: a case report

A Rare Case of Recurrent Cutaneous Non-Hodgkin's Lymphoma in the Extremity: Long-Term Follow-Up and Review of the Literature Written With the Assistance of ChatGPT

Cutaneous involvement of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is uncommon. We report on a 71-year-old male with a history of CLL of the skin in the distal extremities. The patient presented with eruptions of new lesions on the toes of his feet bilaterally, causing significant pain that limited his mobility. Cutaneous involvement of CLL is a rare presentation, and management recommendations are largely based on case reports with limited follow-up. Furthermore, assessing the duration of response, response rates, and correct sequencing of treatment is difficult due to variable use and doses of treatment. The case was treated in 2001 when newer systemic treatments were not available. Therefore, the results can also be directly related to local treatments. Based on a literature review and this case, this report provides insight into the benefits and risks of local treatment for cutaneous involvement of CLL in the extremities and how radiation can be sequenced with other options such as surgical excision and chemotherapy.

Primary Cutaneous Peripheral T-Cell Lymphoma of the Hand: Case Report of a Rare Diagnosis and Review of the Literature

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.

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.
