[Subcutaneous panniculitis-like T-cell lymphoma]

Subcutaneous panniculitis-like T-cell lymphoma is extremely rare and has recently been recognized as a clinicopathological entity. Young female, 17 years old, has complained of subcutaneous nodules and plaques in the limbs and abdomen for three years, accompanied of mild weight loss without other constitutional symptoms. Nodal, visceral and bone marrow involvement was absent, and subcutaneous CD3/CD8 atypical lymphocyte infiltration was observed in the skin sample. Chemotherapy interrupted the onset of new lesions and led to remission in the 8-month follow-up. Immunophenotypic and molecular aspects were relevant to the diagnosis and as prognosis makers.
