Figure 2. (A) Micrograph showing actinomyces colonies surrounded with neutrophile and eosinophile, leucocytes. Abscess formations were seen (H&E, × 40). (B) High power of actinomyces colonies and inflammatory cells (H&E, × 200). (C) Atrophic adrenal glands tissues in the fibrous collagen tissue with chronic inflammatory cells were seen (H&E, × 100).
