case_images: A follow-up PET-CT revealed the uptake of FDG only at the gallbladder (SUVmax 7.1).

case_images: She underwent follow-up PET-CT and FDG uptake was detected at the gallbladder (Fig. 1).
case_images: Contrast abdominal CT showed an early enhanced mass in the gallbladder (arrow) and the enhancement persisted on the equilibrium phase, suggesting gallbladder cancer. (a) Early phase. (b) Equilibrium phase.

case_images: Contrast abdominal CT revealed an early enhanced mass in the gallbladder, and the enhancement persisted in the equilibrium phase (Fig. 2).
case_images: MRI demonstrated that the gallbladder tumor (arrow) showed low signal intensity on T1-weighted images and slightly high on T2-weighted images. (a) T1-weighted images. (b) T2-weighted images.

case_images: On MRI, the tumor showed low signal intensity on T1-weighted images and slightly high intensity on T2-weighted images (Fig. 3).
case_images: The gallbladder tumor was macroscopically soft and whitish measured 7.5 cm x 5 cm in size.

case_images: The tumor was soft, whitish, and measured 7.5 cm x 5 cm (Fig. 4).
case_images: Immunohistochemical examination revealed that the gallbladder tumor was not similar to the original nasal melanoma. HMB-45 staining was far less positive in the gallbladder tumor than in the nasal tumor. (a) Gallbladder tumor, HE staining. (b) Gallbladder tumor, HMB-45 staining. (c) Nasal tumor, HE staining. (d) Nasal tumor, HMB-45 staining (200x).

case_images: Immunohistochemical examination revealed that the tumor was not similar to nasal melanoma, i.e., HMB-45 staining was far less positive in the gallbladder tumor than in the nasal tumor (Fig. 5).
