[Sebaceous cells in repeat biopsies of normal salivary glands and in sebaceous carcinoma of the parotid gland].

One-time examination of the normal tissue of the major salivary glands outside the pathologic foci revealed sebaceous cells in the glandular ducts in about 10% out of 433 patients. In 8 of 45 patients with salivary gland was examined for the second time in a new operation material in necropsy with a time delay of 18 days to 13 years. Sebaceous cells were found in 2 examination in 3 persons, i.e. in almost 38%, which is statistically significantly higher percentage than in the group in the first examination. All 3 observations were positive up to 5 years after repeating excision. Dependence on the patient's age or on the basic diagnosis was not found. In carcinoma of the parotid gland extensive colonies of the sebaceous cells were present in the carcinoma at autopsy of this woman aged 81 a solitary carcinomatous focus in the lung was found 13 years after the removal of the tumor of the parotid gland. Microscopically it revealed the structure of a bronchiologenic carcinoma.
