Abstract
Fig. 1. a Infected adipous tissue. Phyllobothrium delphini located in the center of the well-delimited parasitic cyst. Inset: Phyllobothrium delphini displaying a whitish coloration and shiny appearance. Bar, 2 cm b Thoracic aorta artery displaying bone metaplasia. Radiographic image highlighting the strong radiopacity, similar to bone radiopacity, observed along all the artery walls. Bar, 15 cm c Parasitic cyst located in adipose tissue. Proliferating and reacting fibrous tissue with a moderate number of lymphocytes and plasmocytes located along the parasitic cyst wall. Numerous activated macrophages and multinucleated giant cell (black arrow) are visible around the P. delphini specimen displaying a degenerated cuticle (red arrow). Insert: Hight power field of inflammatory infiltrate with lymphocytes (black arrow) and plasma cells (red arrow). d Thoracic aorta artery displaying bone metaplasia. Mature bone tissue is organized as circumferential lamellae and cement line (red arrow). Note the erythrocytes within the blood vessel and adipose tissue in the medullar region of the detected bone metaplasia. Inset: Hight power field of bone metaplasia with osteocytes allocated in lacunae (black arrow). e Parasitized kidney. Crassicauda sp. involved by reactive fibrous tissue associated with inflammatory infiltrate. f Parasitized Kidney. High power field of nephritis associated with Crassicauda sp. Note the fibrosis and inflammatory infiltrate formed by macrophages (red arrow) and plasma cells (black arrow)..
