[Salivary gland cylindromas. Retrospective study of 65 cases (author's transl)].

A retrospective study of prognostic, clinical, and histological features in 65 cases of salivary gland cylindromas treated in the Hôpital Salpêtrière, Paris, was conducted. Vital prognosis was related to the initial size of the tumour, the presence of pain, and evidence of cellular anomalies or invasion of neighbouring structures on histological examination. Metastatic spread is related to peritumoural extension, and local recurrence has a prognostic value because of its relationship to later metastatic involvement.
