Granuloma annulare (GA) is a rare, [ 1 ] sometimes chronic skin condition which presents as reddish bumps on the skin arranged in a circle or ring. [ 2 ] It can initially occur at any age, though two-thirds of patients are under 30 years old, and it is seen most often in children and young adults.

A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.

An enlarged (hypertrophic) piriformis muscle may place pressure on nearby structures. The empirical evidence supporting this is that ipsilateral (same-side) piriformis hypertrophy is a common image finding in piriformis syndrome, [ 24 ] and that botox injections reduce symptoms (by paralyzing a muscle for months the muscle shrinks).
