A Case of Pulmonary MALT Lymphoma Arising from Lymphocytic Interstitial Pneumonitis
نویسندگان
چکیده
Pulmonary mucosa-associated lymphoid tissue-derived (MALT) lymphoma is a rare disease. This disorder is considered to be a model of antigen-driven lymphoma, which is driven either by autoantigens or by chronic inflammatory conditions. Low-grade B-cell MALT lymphoma may develop from a nonneoplastic pulmonary lymphoproliferative disorder, such as lymphocytic interstitial pneumonitis (LIP). A recent estimate predicts that less than 5% of LIP patients acquire malignant, low-grade, B-cell lymphoma. In Korea, there has been no previous report of malignant low-grade, B-cell lymphoma, acquired from LIP. Here, we present the case of a patient with LIP that developed into pulmonary MALT lymphoma, six years after diagnosis.

We used a PCR and sequence procedure to analyze the Ig V(H) gene and the mutations in the 5' regulatory regions of BCL-6 genes in pulmonary lymphoproliferative disorders (mucosa-associated lymphoid tissue (MALT) lymphoma, HIV-related, EBV-related, and virus-negative lymphocytic interstitial pneumonia (LIP)). Eight of 20 (40%) pulmonary MALT lymphoma and 10 of 20 LIP (5 of 5 (100%) HIV-related, ...

Chlorambucil is an alkylating agent commonly used in treatment of chronic lymphocytic leukemia (CLL). We report a case of interstitial pneumonitis developing in an 83-year-old man 1.5 months after completing a six-month course of chlorambucil for CLL. The interstitial pneumonitis responded to therapy with prednisone. We performed a systematic review of literature and identified 13 other case re...
