Background Intravascular lymphoma is a rare type of lymphoma that frequently affects the skin and is usually of B‐cell origin. This lymphoma type is very rare and not recognized as a separate entity in the 2008 World Health Organization classification of hematopoietic and lymphoid tissue tumors. Methods We reported five cases of intravascular NK /T cell lymphoma with cutaneous manifestation and reviewed 12 published cases involving Chinese patients with similar characteristics. Results All five patients were adults who exhibited red or brown patches or plaques on the lower extremities or trunk; four cases were associated with B symptoms; one case developed subsequent to a lymphoma on the face (possibly extranodal NK /T cell lymphoma, nasal type). Histopathologically, all patients exhibited abnormal, medium‐sized intravascular lymphocytes in the dermis and subcutaneous tissues. All patients were positive for CD2 , CD3ϵ , CD56 and cytotoxic proteins. All cases were Epstein‐Barr virus ( EBV ) positive. Four of FIVE patients died of lymphoma within a few months of diagnosis. Conclusions Intravascular NK /T‐cell lymphoma is a rare highly aggressive and EBV ‐associated lymphoma that is prone to develop in Chinese patients. The relationship between intravascular NK /T‐cell lymphoma and extranodal NK /T‐cell lymphoma, nasal type, requires clarification.
