NCI Definition: A T-cell non-Hodgkin lymphoma arising from the skin. Representative examples include mycosis fungoides and primary cutaneous anaplastic large cell lymphoma. [1]

Primary cutaneous T cell non-hodgkin lymphomas most frequently harbor alterations in KMT2D, CDKN2A, CDKN2B, ARID1A, and TET2 [2].

Most Commonly Altered Genes in Primary Cutaneous T Cell Non-Hodgkin Lymphoma

KMT2D Mutation, CDKN2A Loss, CDKN2B Loss, TET2 Mutation, and ARID1A Mutation are the most common alterations in primary cutaneous T cell non-hodgkin lymphoma [2].
