Background:
The clinicomorphology and immunohistochemical features of T-cell lymphomas have been documented.
Aim:
The aim of the study was to evaluate the spectrum of clincopathological features of T-cell lymphoma with immunohistochemistry correlation in a tertiary care center.
Materials And Methods:
The present study was conducted on 19 biopsy specimens received from the Department of Pathology, Kasturba Medical College, from referral hospitals of Mangalore city. Cases of nodal and extranodal T-cell lymphomas diagnosed between January 2012 and December 2015 were selected with evaluation of clinical data, histomorphological features, and immunophenotyping. Appropriate panel of antibodies was chosen after morphological evaluation of the cases.
Results:
Of the 19 cases of T-cell lymphomas, 14 were nodal disease and 5 were extranodal disease. Among the nodal lymphomas, five were primary peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS), four were cases of lymphoblastic lymphoma, three were cases of angioimmunoblastic T-cell lymphomas, and two were cases of anaplastic large-cell lymphoma anaplastic lymphoma kinase (ALK) negative. In extranodal disease, two were mycosis fungoides of skin, one case each of subcutaneous panniculitis-like T-cell lymphoma, T-cell lymphoblastic lymphoma of tonsil, and T-cell lymphoma of the stomach.
Conclusions:
The diagnosis and subclassification of PTCLs is necessary for therapeutic and prognostic purposes.
