Gular Cutaneous Fibrosarcoma and Anatomophysiological Considerations for Anaesthesia in a Saddled Bichir, Polypterus endlicheri endlicheri

Figure 2

Firm, spherical, centrally ulcerated mass in the gular region of a saddled bichir (Polypterus endlicheri endlicheri) on clinical presentation, 1 week after first observation. The mass emerges from tissue deep to the axial margins of gular plates, pushing the plate margins abaxially.
