Cutaneous non-Hodgkin's lymphoma of the foot: a rare 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.

A Rare Presentation of Transformed, CD30(+) High-Grade Cutaneous T-Cell Lymphoma of the Hallux A Case Report

Cutaneous T-cell lymphoma is a type of non-Hodgkin's lymphoma, which is a neoplasm affecting the lymphatic system. Mycosis fungoides is the most common subset of cutaneous T-cell lymphoma and is often treated conservatively. This neoplasm is most common in adults older than 60 years and does not regularly manifest in the toes. A case is reported of a 70-year-old man seen for a nonhealing hallux ulceration leading to amputation. Histopathologic examination revealed a rare transformed CD30(+) high-grade cutaneous T-cell lymphoma. The morbidity of lymphomas is highly dependent on type and grade. Pharmaceutical precision therapies exist that target specific molecular defects or abnormally expressed genes, such as high expression of CD30. This article focuses on treatment protocol and emphasizes the importance of early diagnosis, determination of cell type, and proper referral of atypical dermatologic lesions.

Concomitant acute osteomyelitis and squamous cell carcinoma of the foot: a case report

Squamous cell carcinoma of the foot is a common malignant neoplasm with a high potential for metastasis. Squamous cell carcinoma arising in chronic osteomyelitis has been widely reported; however, its presence in combination with acute osteomyelitis of the foot is not well known. This article presents such a case that demonstrates the importance of early recognition with appropriate management for limb salvage and successful oncologic outcome.
