History Of

We present the extraordinary case of a 72-year-old man with a history of primary cutaneous peripheral T-cell lymphoma not otherwise specified (pcPTCL-NOS) previously controlled with topical agents who developed tumours in a sporotrichoid pattern. Culture of the tumours was negative, and histopathology showed findings consistent with recurrent pcPTCL. The tumours were successfully treated with localised radiation therapy. Sporotrichoid lesions are an extremely rare and atypical presentation of cutaneous lymphoma, with only 2 other cases reported in the literature. Our case reinforces the need to include cutaneous lymphoma in the differential diagnosis of nodules on the extremities spreading in a sporotrichoid pattern. Clinical recognition of this atypical presentation of cutaneous lymphoma allows for prompt, effective treatment, which might include localised radiation therapy.

We report the case of a 40-year-old male presented with a painless right testicular swelling. Right radical orchidectomy was performed. The pathological diagnosis was peripheral T-Cell lymphoma-not otherwise specified (PTCL-NOS). According to Ann Arbor staging, the initial clinical stage was IEa. Treating him with four courses of the CHOEP protocol and intrathecal prophylactic chemotherapy was unsuccessful; with the appearance of orbital infiltration and a loco-regional extension. Although the patient started a second line chemotherapy, he unfortunately succumbed to death.

AbstractPeripheral T-cell lymphoma (PTCL) is a heterogeneous group of non-Hodgkin lymphomas with poor prognosis. Up to 30% of PTCL lack distinctive features and are classified as PTCL, not otherwise specified (PTCL-NOS). To further improve our understanding of the genetic landscape and biology of PTCL-NOS, we perform RNA-sequencing of 18 cases and validate results in an independent cohort of 37 PTCL cases. We identify FYN-TRAF3IP2, KHDRBS1-LCK and SIN3A-FOXO1 as new in-frame fusion transcripts, with FYN-TRAF3IP2 as a recurrent fusion detected in 8 of 55 cases. Using ex vivo and in vivo experiments, we demonstrate that FYN-TRAF3IP2 and KHDRBS1-LCK activate signaling pathways downstream of the T cell receptor (TCR) complex and confer therapeutic vulnerability to clinically available drugs.

Bexarotene is a third-generation retinoid X receptor-selective retinoid that is widely used for the early treatment of advanced-stage cutaneous T-cell lymphomas. In this report, we describe a case of successful treatment of advanced primary cutaneous peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) with oral bexarotene monotherapy. After the administration of oral bexarotene at a dose of 300 mg/m2/day, all skin lesions and lymph nodes regressed, and complete remission was achieved for 1 year. Our case suggested that bexarotene monotherapy could be one of the possible therapies for the treatment of primary cutaneous PTCL-NOS.
