Twenty three cases of parotid gland pleomorphic adenoma from Surgical Oro-Maxillo Facial Clinic of "Sf. Spiridon" Hospital, Iaşi, have been evaluated. In order to reveal the particular microscopic aspects, several histological techniques have been used: HE, Van Gieson, PAS, Alcian Blue and Gordon Sweet. The microscopic evidences points out the variety of microscopic forms even within the same case, and also the prevalence of some particular forms such as myo-epithelial cell predominance, squamous metaplasia and cystic degeneration. Our observations, corroborated with the one from other research, support the hypothesis of an unique ectodermal cell origin for the lesion histogenesis.
