FIGURE 2

Immunoglobulin heavy-chain gene rearrangement polymerase chain reaction (VDJ-PCR) of representative cases of lymphoid interstitial pneumonitis (LIP) and pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma in HIV-infected pediatric patients. A, two representative cases of LIP showing a polyclonal pattern (Cases 3 and 5, Tables 1 and 2); B, a representative case of pulmonary MALT lymphoma showing a dominant monoclonal band with a background polyclonal ladder (Case 6, Tables 1 and 2); C, the patient with concurrent pulmonary MALT lymphoma and LIP; note that the LIP lesion showed a band slightly increased in intensity and of the same size as the monoclonal band amplified from the pulmonary MALT lymphoma lesion.
