Abstract: Objective :To explore the clinical presentations and pathologic features of the subcu-taneous panniculitis-like T cell lymphoma and to review the literature in order to improve its diagnosis. Methods : Three cases of subcutaneous panniculitis-like T cell lymphoma were collected, and the clin-ical, pathologic, and immunohistochemical features were analysed. Results : Two cases of male and 1case of female patient were included. The age of the patients ranged from 5 to 42. The lesions were lo-cated on chest wall, back, limbs and breast, etc. They were presented with single or multiple cutaneouserythematous lesion and subcutaneous nodules. The pathologic features may consist of infiltrations ofatypical small, intermediate and large sized lymph cells, infiltrated subcutaneous lipid tissue as panni-culitis pattern with vasculitis, coagulation necrosis, and phagocytic reaction. Of them, one case ofhemophagocytic phenomenon were present. CD45RO were expressed in the tumor cells of all 3 cases.CD 20 was not expressed. CD68 was expressed in the phagocytes of all 3 cases. Resections of the locallesions were performed in all 3 cases. Loss of the follow-up was in 1 case, the progression of diseaseswas slow. There was a lack of systemic symptom, and the follow-up visit was 3 years and 8 months, re-spectively. Conclusion : This is an unique type of cutaneous lymphoma consisted of infiltrations of tu-morous T cells into subcutaneous fat. Its prognosis should be associated with the clonality of T cells.
