The lesion consisted of an itchy erythematous nodule measuring 2<span class="elsevierStyleHsp" style=""></span>cm in diameter with a smooth surface (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Biopsy showed a dense and diffuse infiltrate that occupied the entire thickness of the dermis, composed of small and medium sized cells alongside some eosinophils (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Epidermotropism was scarce. Abundant histiocytes and multinucleated giant cells were also observed, forming granulomatous aggregates (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>), interspersed with lymphoid proliferation. Immunohistochemistry showed CD3+ and CD4+ cells that were however negative for CD8 and CD30 (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>). Molecular study of the λ chain of the T-cell receptor showed monoclonal rearrangement, and so the patient was diagnosed with primary cutaneous granulomatous small-to-medium sized CD4+ T-cell lymphoma. An extension study was conducted, including study with lymphoid subpopulations, LDH, β2-microglobulin, and positron emission tomography-computed tomography, with normal results. Surgical resection was proposed. On the day of surgery, 2 months later, the nodule had disappeared to leave a residual erythematous macule (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Excision biopsy of the lesion showed a considerable reduction in lymphoid infiltrate, but this remained positive for CD20, CD3, and CD68, with predominance of CD4 over CD8; the infiltrate was negative for CD30.
