Abstract
ABSTRACT We report a 48-year-old man with CD30+ large cell transformation of mycosis fungoides (tMF) with distinctive anaplastic morphology. The patient initially presented with folliculotropic and syringotropic mycosis fungoides (MF) manifested as occipital scalp plaque and trunk and extremities patches. Six years later, he progressed to the tumor stage from his scalp lesion and developed cervical lymphadenopathy. Lymph node and scalp biopsies showed diffuse infiltration of CD30+ anaplastic cells with multinucleated, hallmark-like, Hodgkin-Reed-Sternberg-like, histiocytoid forms, indistinguishable from anaplastic large cell lymphoma (ALCL). T-cell receptor gamma gene (TCRg) rearrangement studies revealed identical clones in the initial MF scalp lesion and nodal anaplastic lesion, confirming the transformation. Ancillary studies showed absence of IRF4/DUSP22 and ALK rearrangements and positive RB1, SMARCA4, SOCS1, and TP53 mutations. The patient achieved partial response with systemic chemotherapy. Our case is an example of tMF presenting as the morphology and phenotype of ALCL. Because clinical behavior and therapeutic options of tMF and primary cutaneous ALCL may be different, it is clinically relevant to differentiate these 2 entities. The proof of clonal relationship may be useful in diagnostically challenging cases with features overlapping between tMF and primary cutaneous ALCL.

Abstract
Peripheral T-cell lymphomas (PTCL) comprised more than 30 rare heterogeneous entities, representing 10 to 15% of adult non-Hodgkin lymphomas. Although their diagnosis is still mainly based on clinical, pathological, and phenotypic features, molecular studies have allowed for a better understanding of the oncogenic mechanisms involved and the refinement of many PTCL entities in the recently updated classifications. The prognosis remains poor for most entities (5-year overall survival < 30%), with current conventional therapies based on anthracyclin-based polychemotherapy regimen, despite many years of clinical trials. The recent use of new targeted therapies appears to be promising for relapsed/refractory patients, such as demethylating agents in T-follicular helper (TFH) PTCL. However further studies are needed to evaluate the proper combination of these drugs in the setting of front-line therapy. In this review, we will summarize the oncogenic events for the main PTCL entities and report the molecular targets that have led to the development of new therapies. We will also discuss the development of innovative high throughput technologies that aid the routine workflow for the histopathological diagnosis and management of PTCL patients.

Targeted Deep Sequencing of Mycosis Fungoides Reveals Intracellular Signaling Pathways Associated with Aggressiveness and Large Cell Transformation. Cancers (Basel) 2021; 13:5512.

Abstract
INTRODUCTION Large-cell transformation (LCT) of mycosis fungoides (MF) has been associated with a higher risk of relapse and progression and, consequently, restricted prognosis. Its molecular pathogenesis has not been elucidated yet. MATERIALS AND METHODS In order to address molecular mechanisms of LCT, we performed hybrid capture panel-based sequencing of skin biopsies from 10 patients suffering from MF with LCT versus 17 patients without LCT including follow-up biopsies during clinical course, respectively (51 samples in total). The analyzed patients were attributed to three different groups based on the presence of LCT and clinical behavior. RESULTS While indolent MF cases without LCT did not show pathogenic driver mutations, a high rate of oncogenic alterations was detected in patients with LCT and aggressive clinical courses. Various genes of different oncogenic signaling pathways, including the MAPK and JAK-STAT signaling pathways, as well as epigenetic modifiers were affected. A high inter-individual and distinctive intra-individual mutation diversity was observed. Oncogenic RAS mutations were exclusively detected in patients with LCT. CONCLUSION Our data demonstrate that LCT transition of MF is associated with increased frequency of somatic mutations in cancer-associated genes. In particular, the activation of RAS signaling-together with epigenetic dysregulation-may crucially contribute to the molecular pathogenesis of the LCT phenotype, thus conveying its adverse clinical behavior.
