Heterotopic tissue found many locations throughout head neck. Age-induced variations reactive changes include oncocyte proliferation, fatty infiltration, squamous mucous metaplasia, hyperplasia, atrophy, regeneration. An analysis structure permits morphogenetic approach understanding variability histologic types
