Intravascular lymphoma (IL) is a rare variant of non‐Hodgkin lymphoma with a predilection for skin. Most reported cases are large B cell lymphomas. Intravascular anaplastic large cell lymphoma (IALCL) is extremely rare. Retrospective analysis of a case of cutaneous IALCL was performed. Hematoxylin and eosin stained sections and immunohistochemical staining results were analyzed. The patient was a 47‐year‐old woman who had developed multiple erythematous patches and plaques on her back. The lesions responded well to CHOP (cyclophosphamide, hydroxydoxorubicin, oncovin, prednisone) chemotherapy, but relapsed shortly after therapy. The patient was surviving with the disease for eight years but was ultimately lost to follow up. Histopathologically, the neoplasm evolved from IL to extravascular lymphoma. This was showed in biopsies obtained at different stages of the disease. The lymphoma cells stained positively for CD30, CD45, CD3, CD4, CD5 and Ki67, and lacked expression of anaplastic lymphoma kinase (ALK), CD8, CD45RA, CD45RO, CD20, CD79, CD56, perforin and granzyme B. Our results suggest that IALCL represents a distinct subtype of IL and is histopathologically and biologically different from IL with B, NK or T cell phenotype. Wang L, Li C, Gao T.
