case_images: Changes in skin lesions before and after anti-amoeba treatment. Images (A1-A4) show the ulcers of the right upper limb (A1), the right lateral chest wall (A2), the right hip (A3), and the subcutaneous nodule of the right lower leg (A4) before treatment, respectively. These lesions were significantly improved after anti-amoeba treatment (B1-B4).

case_images: Subcutaneous nodules had mild tenderness and were poorly demarcated from surrounding tissues (Figure 1).
case_images: Upper palate defect and maxillofacial CT scan image. There is a defect of approximately 1 cm in diameter on the upper palate (A, B), and the CT scan shows the thickening and enhancement of the nasal mucosa (C). The white arrow indicates the defect.

case_images: The patient's oral mucosa had leukoplakia and a sinus tract with a diameter of approximately 1 cm in the upper palate that communicated with the nasal cavity (Figure 2A). Maxillofacial computed tomography (CT) scan demonstrated thickening and enhancement of the sinus mucosa and partial tissue defects in the hard palate and nasal septum (Figures 2B,C).
case_images: Histology and cytology findings. (A) The histological study of subcutaneous mass in the right hip showed granulomatous inflammation and amoeba trophozoites (hematoxylin and eosin, 200x). (B) The cytological study of ulcer surface secretion showed amoeba trophozoite (Wright-Giemsa stain, 400x). The black arrows indicate amoeba trophozoites.

case_images: Trophozoite-like structures were observed, which are considered to be indicative of an amoebic infection (Figure 3A). Cytological examination of ulcer surface secretion also found amoebic trophozoite (Figure 3B).
