VILLARROEL S, JULIO C et al. Primary pulmonary lymphoma: A case serie. Rev. chil. enferm. respir. [online]. 2014, vol.30, n.1, pp.35-39. ISSN 0717-7348.

Primary Pulmonary Lymphomas (LPP) are infrequent and their clinical manifestations and images are usually nonspecific. Diagnostic delay may be important. The objective of this study was to analyze the LLP in our institution. Between 2003 and 2013, over 1,892 lymphomas were analyzed in our institution. Only 4 of them (0.21% incidence) were detected as LPP: Non Hodgkin's Lymphoma (n = 2), Hodgkin's Lymphoma (n = 1), and Intravascular Pulmonary Lymphoma (n = 1). Clinical manifestations of the 4 cases presented were unspecific: 1) pulmonary mass and pleural effusion; 2) consolidation with air bronchogram and cavitations; 3) normal images and 4) pulmonary mass. Given these clinical settings, 4 diagnostic methods were used: 1) Computed Tomography-Guided Puncture, 2) Video-Assisted Thoracoscopic Surgery (VATS); 3) VATS guided by positron emission tomography (PET) and 4) thoracotomy. Hence, diagnosis was successfully made between 45 to 90 days from the initial consultation. This report confirms the low incidence of LPP, and its unspecific clinical and radiographic manifestations that may cause delay in diagnosis. PET can contribute to improve diagnostic performance, especially in patients without apparent lung involvement.
