[Occult adenocarcinoma of the parotid. Apropos of 2 cases]

The authors present two cases of parotid gland adenocarcinomas, without clinical swelling: revealed differently: one by facial paralysis; the other by mandibular extent signs, but setting altogether, some problems to explain their histogenesis; primitive or metastatic adenocarcinoma in the first observation; primary gland tumor, or transformation of a pleomorphic adenoma in the second one. The authors insist on the facial paralysis value, to guide the surgical approach.
