title: Pulmonary mantle cell lymphoma: a rare manifestation of an uncommon condition.
abstract: Herein we describe the case of a 64-year old man with a history of mantle cell lymphoma found to have evidence of pulmonary parenchymal involvement by recurrence of his lymphoma. While lung involvement is not necessarily uncommon with Non-Hodgkin's lymphomas as a group, it is very rare for mantle cell lymphoma to involve the lung parenchyma. In addition, the radiographic manifestation of his pulmonary lymphoma as a discrete FDG-avid ground-glass lesion on chest imaging was also distinctly uncommon for pulmonary lymphoma which classically appears in one of three patterns: scattered ill-defined nodules, a bronchovascular/lymphangitic process, or pneumonic/alveolar consolidation effectively indistinguishable from bacterial pneumonia. Due to significant underlying lung disease our patient was not a candidate for high-dose conditioning and autologous stem cell transplantation. He was ultimately treated with rituximab and cladribine therapy and had early signs of clinical response at last correspondence.
