A 52-year-old asymptomatic man was evaluated for two right lung lesions
discovered on a chest roentgenogram during a routine physical examination.
A computed tomographic scan revealed the absence of mediastinal nodal
involvement. Guided-needle aspiration cytology was inconclusive. A
subsequent right thoracotomy was necessary to perform biopsy of these
masses, which proved to be B-cell malignant lymphomas of the lung. This
case represents a rare example of a primary low-grade B-cell pulmonary
lymphoma of mucosa-associated lymphoid tissue, with its distinct
clinicopathologic features.
