Cutaneous Coinfection of Cytomegalovirus and Mycobacterium chelonae Accelerated by Immunosuppression

Figure 4

Gram-positive acid-fast bacilli in the second (a–c) and third (d–f) biopsy specimens ((a, d) H&E, (b, e) Ziehl-Neelsen stain, and (c, f) Gram stain). Gram-positive acid-fast bacilli are multifocally clustered in microabscess (a–c) and also in fat droplets located in the center of suppurative granuloma (d–f). The bacteria are visible in the fat droplets even in H&E preparations (d). Such patterns of bacterial colonization are seen in both the second and third biopsy specimens.
