Figure 2. Typical histology of 1 cm³ lung tissues of three NTM-LD patients showing abundant number of lymphocytes. Lymphocytes were typically found more diffusely across the tissues but occasionally in varied sized clusters, sometimes quite large (middle panel). Note the apparent lack of neutrophils.

PMN, polymorpho-neutrophils; Mono, monocytes; LL, large lymphocytes; SL, small lymphocytes.
