[A rare case of multiple primary malignant neoplasms of parotid gland: fibrosarcoma and squamous cell carcinoma].
Primary multiple malignant neoplasms and multifocal neoplasms are a very complex problem and therefore have been a topic of many articles. The mechanism of origin, frequency of occurrence, co-existence of neoplasms in functionally similar organs (uterus, mammary gland), heredity, a possibility of diagnostic and therapy are the most interesting aspects. Frequency of multiple primary malignant neoplasms occurrence is about 2-8% and still increases. Pathogenesis of multifocal and multiple neoplasms has rarely been a subject of articles. A simultaneous exposure of a tissue to damaging factors and special tissue sensitivity are the main reasons for neoplasms origin in this group. The authors present a rare case of parotid gland multiple neoplasm: fibrosarcoma and squamous cell carcinoma, as well as discuss the diagnostics, therapy, and prognosis of multiple neoplasms.
