Abstract
Background: Cutaneous lymphomas are a heterogeneous group of extra-nodal non-Hodgkin’s lymphomas that are characterized by a cutaneous infiltration of malignant monoclonal lymphocytes. Less frequently, these lymphomas spread from the skin to the blood or a lymph node. The incidence of primary cutaneous lymphoma has been estimated to be 1:100,000 according to the World Health Organization. Usually, these lymphomas affect adults with a median age of 50 to 60 years. T-cell lymphomas predominate over primary B-cell lymphomas of the skin. The most important subtypes of cutaneous T cell lymphomas are Mycosis fungoides, Sezary syndrome, and primary cutaneous peripheral T cell lymphomas not otherwise specified. These subtypes present different clinical, histological, and molecular features, and can follow an indolent or a very aggressive course.
Aim: The aim of this study was to analyze cutaneous lymphomas to ascertain its clinical aspects including prevalence, histopathology and immune profile.
Material and methods: A retrospective analysis of skin biopsies over a 7-year period ranging from 2016 to 2022 was done, of which 11 cases were diagnosed as cutaneous lymphomas. These cases were analyzed in detail including immune profile.
Results & conclusions: The majority of the cases out of all cutaneous lymphomas were of T cell lymphoma and only one case was of B cell type. Definitive diagnosis of CTCL requires a multidisciplinary approach.
Keywords: cutaneous T cell lymphoma, cutaneous B cell lymphoma.
