    ABSTRACT: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is an uncommon type of skin lymphoma. The natural history, optimal treatment strategy, and prognostic factors associated with this malignancy are not well defined. The authors performed a systematic analysis of all patients with SPTCL reported on in the English-language medical literature, with emphasis on specific clinical features, experiences involving the use of radiotherapy and systemic agents, and prognostic factors predictive of treatment response and clinical outcome. One hundred fifty-six patients with SPTCL were identified in the literature. Hemophagocytic syndrome (HPS) was a presenting feature in 37% of patients, and > 90% of patients required treatment at diagnosis. Prednisone was used frequently as initial therapy in patients who had less aggressive disease at presentation; however, durable complete remissions (CR) were infrequent. Anthracycline-based chemotherapy regimens were the most commonly used and most effective systemic treatment options, producing long-term CR in approximately 30% of patients. Among patients who received high-dose chemotherapy and stem cell transplantation (HDT-SCT) for refractory or recurrent disease, 92% achieved CR, with a median response duration of > or = 14 months. The presence of HPS at diagnosis and expression of the gamma/delta T-cell receptor (TCR) by tumor cells were associated with poor survival, whereas age was not. After a median follow-up of 24 months, 48% of patients died of disease. The median survival duration was 27 months. SPTCL has an aggressive natural history. Nonetheless, a subgroup of patients with SPTCL can have long-term disease remission following anthracycline-based initial therapy or subsequent HDT-SCT. HPS and the TCR phenotype may be useful prognostic markers for patients with this malignancy.

    ABSTRACT: Panniculitis-like T-cell lymphoma is an uncommon type of extranodal T-cell lymphoma which presents clinically with subcutaneous nodules. The clinical course can either be indolent or rapidly progressive, often complicated by hemophagocytic syndrome. We report a patient with primary subcutaneous disease and initial complete response to combination chemotherapy. The patient experienced an early relapse which responded to salvage chemotherapy. However, she died shortly thereafter with hemophagocytic syndrome, polymicrobial sepsis and systemic fungal infection. At autopsy there was no evidence of lymphoma in the bone marrow or other organs. We emphasize that a fatal hemophagocytic syndrome can occur despite minimal or even without evidence: of clinically active lymphoma as demonstrated by autopsy in this case.

    ABSTRACT: Pentostatin (Nipent; SuperGen, San Ramon, CA), which is highly lymphocytotoxic, is an active agent in hairy cell leukemia. We therefore initiated a trial of this agent in T-cell lymphomas. Pentostatin was administered at a dose of 3.75 or 5.0 mg/m2/d intravenously for 3 days every 3 weeks to heavily pretreated patients with cutaneous and peripheral T-cell lymphomas. To date, there are 24 evaluable patients in the trial. Seventeen of these individuals have responded (complete or partial remission). The most common toxicities included granulocytopenia, nausea, renal insufficiency, CD4 suppression, and delayed herpes zoster. Pentostatin is an active agent in this group of diseases and merits further exploration.
