Abstract

Pseudolymphoma of the lung refers to a reactive lymphoid proliferation characterized by the formation of a mass lesion. It may be difficult to distinguish from malignant lymphoma by morphology alone, but the criteria proposed by Saltzstein have been widely accepted to identify pseudolymphoma; presence of mature lymphocytes, presence of germinal centers and absence of involvement of hilar lymph nodes. Chest radiography demonstrates one or more nodular lesions, usually unilateral, but occasionally involving both lung We experienced two cases of pulmonary pseudolymphoma which showed uncommon radiological findings. One showed pulmonary consolidating infiltrations and the other showed direct bronchial invasion. We report them with a brief review of literature.
