Figure

Histologic sections of resected Taenia martis metacestode from a patient in Switzerland. A) Cross-section through the excised tissue revealed strong infiltration surrounding a structure suggestive of parasitic origin. Boxed areas are shown in a higher magnification in panels B and C. B, C) The metacestode’s cyst wall, showing the warty appearance (B) characteristic of tapeworm metacestodes’ tegument (3,4). Hematoxylin and eosin stain. Scale bars indicate 200 μM (A), 10 μM (B), and 100 μM (C).
