[Phosphatidilinositides content study in patients with benign and malignant tumors of parotid gland].

Phosphatidilinositides content in lymphocytes, monocites and tumor tissues in 32 patients with benign and in 16 patients with malignant parotid gland tumors was investigated by the authors. It was found that the level of phosphatidilinositides content in blood lymphocytes and monocites in patients with benign tumors was significantly different from their values in patients with malignant tumors and this may be used in complex differential diagnostics.
