Abstract |
Peripheral T-cell lymphomas not otherwise specified are generally considered aggressive non-Hodgkin lymphomas, because of poor natural outcome and response to therapy. They show a complex karyotype without any specific genetic hallmark. We report a case of peripheral T-cell lymphoma not otherwise specified with heterogeneous nuclear cyclin D1 immunohistochemical overexpression, due to gene copy gain, a phenomenon similar to that observed in mantle cell lymphoma characterized by t(11;14)(q13;q32). In this case report we underline the diagnostic pitfall represented by cyclin D1 immunohistochemical overexpression in a T-cell lymphoma. Several pitfalls could lead to misinterpretation of diagnosis, therefore, we underlined the need to integrate the classical histology and immunohistochemistry with molecular tests as clonality or fluorescence in situ hybridization. |
