Abstract
Cutaneous T-cell lymphomas are part of non-Hodgkin lymphomas that mainly affects the skin but can compromise blood, lymph nodes and other internal organs in patients with advanced disease. There are many types of cutaneous T-cell lymphoma. The two main subtypes are mycosis fungoides (MF) and Sézary syndrome (SS). The diagnosis of the latter is a challenge due to the clinical and some histological findings, which makes them similar to benign dermatoses. The clinical case of a patient with an initial diagnosis of erythroderma associated with psoriasis with joint involvement is presented, then the etiology is re-evaluated and an extra cutaneous nodal T lymphoma with bone marrow involvement (Sézary syndrome) is confirmed.
