Primary pulmonary T-cell lymphoma.

Primary pulmonary lymphoma (PPL) is a rare clonal proliferation of lymphoid tissue involving one or both lungs. It is of two types, B-cell and T-cell lymphomas among which T-cell lymphoma is a rare entity and it is sparsely considered as a differential diagnosis in neoplastic lesions of the lung. Here, we are reporting a case of primary pulmonary T-cell lymphoma. PPL is a rare disease and can present with nonspecific symptoms. Radiologically, it can easily be confused with more common malignancies such as bronchogenic carcinoma with or without metastases. PPL carries different therapeutic and prognostic implications. Therefore, physicians should make every effort to achieve histopathological diagnosis before prognosticating a patient presenting with lung cancer.
