Context: Peripheral T cell lymphomas (PTCLs) are uncommon subtypes of non Hodgkin lymphoma (NHL). The diagnosis is often challenging and not infrequently misdiagnosed. Aims: To analyse the morphological and immunohistochemical profile of Peripheral T cell lymphoma. Settings and Design: This study was carried out at the Department of Pathology, where cases were recruited using consecutive sampling method. Methods and Material: Immunohistochemical staining was performed in all cases of lymphoma and results were analysed. Statistical Analysis Used: Frequency distribution of the diagnoses was studied. Results: There were six casesof Peripheral T cell lymphoma – unspecified ( CD3+, CD20), two cases of Angioimmunoblastic T cell lymphoma (AITL)(CD3+, CD10+, CD23+), one case of Lennert’s lymphoma(CD3+,CD20) and a hepatosplenic T cell lymphoma(CD3+,CD2+). Conclusions: PTCLs constituted for 20% of NHLs. Immunohistochemistry was helpful in diagnosis when differentiation from Hodgkin lymphoma was difficult morphologically.
