The cutaneous papule and the lymph node showed the same pathologic features. The hematoxylin-eosin–stained sections demonstrated the presence of a granulomatous infiltrate with multinucleated Langerhans-type giant cells and calcified spherules resembling psammoma bodies or Schaumann bodies (Figure 2 and Figure 3). Fite-stained sections demonstratedthe presence of a few acid-fast bacilli (Figure 4). A mycobacterial culture of the lymph node was negative. On polymerase chain reaction testing, the lymph node was positive for Mycobacterium bovis BCG. A purified protein D test result was positive.
