What could be the reason for finding a palm-sized lump in the upper right abdomen?

A palm-sized mass has been found in the upper right abdomen, which may be caused by several possible conditions: 1. Intestinal tuberculosis or appendiceal abscess: This type of mass could result from inflammatory diseases such as intestinal tuberculosis or appendiceal abscess, and further examination is needed for confirmation. 2. Abdominal fibroma or lipoma: Abdominal fibromas or lipomas may also form a mass in the upper right abdominal area, especially when they grow large enough to reach the size of a palm. 3. Liver diseases: Conditions including hepatitis, liver abscess, hepatic hemangioma, liver cysts, and particularly liver cancer, may present as a mass in the right upper abdomen, possibly accompanied by systemic symptoms such as fatigue and weight loss. 4. Biliary tract diseases: Cholecystitis, biliary obstruction, and other biliary tract disorders may also lead to the formation of a localized mass.
