Development of Bullous Disease during Treatment of Pulmonary Marginal Zone B-Cell Lymphoma
Figure 1
(a) Sections of intraparenchymal lymph node revealing complete effacement of normal nodular architecture by monotonous proliferation of small monocytoid lymphoid cells typical of marginal zone B-cell lymphoma. (b) Lung biopsy showing morphologically pulmonary lymphoid infiltrates with small lymphocytes distributed along the interlobular septae, visceral pleura and vessels, consistent with pulmonary parenchymal involvement by lymphoma. (c) Section of the pulmonary parenchyma showing normal alveolar architecture except in areas close to lymphocytic infiltration where microscopic bullae are seen.
