case_images: Thoracentesis was performed based on clinical signs of pleural effusion, and 120 ml of foul-smelling fluid was drained from the right side and 230 ml from the left side, with rosy color and flocculated appearance (Figure 1).
case_images: Dermal lesions located between the shoulder blades. Diagnosis of eosinophilic plaques was confirmed after cutaneous cytology.

case_images: No images were suggestive of remnant pleural effusion (Figure 3).
case_images: Cellular predominance of mildly degenerated neutrophils and high presence of phagocytosed filamentous bacteria at the bottom of the slide (red arrows). Fast panoptic staining was used for optical microscopy with 1000x magnification.
