Eight weeks later, he developed a maculo\u2010papulous eruption, edema of the extremities, fever and blood eosinophilia. Cutaneous biopsy revealed an atypical T\u2010cell proliferation into the dermal lymphatic vessels. The lymphocytes were mid\u2010sized, with mitoses and apoptotic figures. They were CD3+, CD4+, CD5+ and some were CD30+. There was no T\u2010cell receptor (TcR) clonal rearrangement. Complete regression of cutaneous eruption and eosinophilia was observed after ceasing treatment with antibiotics. The diagnosis was that of a benign atypical intralymphatic T\u2010cell proliferation associated with DRESS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>The occurrence of atypical dermal CD30+ T\u2010cells in cutaneous biopsy during benign reactive conditions such as arthropod bites or scabies is well\u2010known. The intralymphatic localization of such atypical reactive lymphocytes is much less common and represents a diagnostic pitfall because it can suggest aggressive intravascular lymphoma.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We report the first case of benign atypical intralymphatic CD30+ T\u2010cell proliferation associated with DRESS.
