Genetic profiles and clinical features in subcutaneous panniculitis-like T-cell lymphomas.

ABSTRACT: Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare peripheral T-cell lymphoma characterized by cutaneous lesions and immunologic manifestations. The five-year survival rate of SPTCL has been reported to be over 80%, indicating a favorable prognosis. Recent studies have uncovered recurrent germline variants in HAVCR2, encoding an immunomodulator. In this study, we integrated whole-exome sequencing data from 60 samples collected from 36 SPTCL patients, encompassing six patients of our cohort and 30 patients of publicly available data. We identified 138 somatic mutations in skin tumors of 24 patients and HAVCR2 germline mutations in 23 of 29 patients. HAVCR2 p.Tyr82Cys mutations were identified in four of six Japanese patients. During the clinical courses of four patients, cyclo
