One month later, the patient presented with a notable worsening of symptoms, with the onset of large swollen lymph nodes on the right side of the groin. Another skin biopsy (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>) showed a T lymphoid infiltrate with epidermotropism and abundant eosinophils and a lymph node biopsy revealed complete loss of architecture (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>). These cells were positive for CD3, CD4, and CD5, with loss of CD7, and negative for CD8, CD20, and CD30, presenting monoclonality for TCR beta and gamma. Likewise, the presence of Sézary cells in peripheral blood was ruled out, as well as systemic involvement. These findings led to diagnosis of erythrodermic mycosis fungoides with lymph node involvement (stage IVA2). In accordance with this diagnosis, prednisone 45<span class="elsevierStyleHsp" style=""></span>mg/24<span class="elsevierStyleHsp" style=""></span>h, interferon alfa 2a 3 MIU (3 injections per week), bexarotene 300<span class="elsevierStyleHsp" style=""></span>mg/24<span class="elsevierStyleHsp" style=""></span>h, and weekly methotrexate 20<span class="elsevierStyleHsp" style=""></span>mg were administered.
