Gigantism, focal: Extreme growth of specific body parts, such as one arm, the tongue, or a combination of parts, as seen in Beckwith-Wiedemann syndrome or acromegaly. Focal gigantism may occur before or after the bones fuse. If it occurs afterward, it causes disfigurement. Surgery for mass reduction can help improve function, and other treatments may be available for specific conditions.
