[Primary extragenital manifestation of a malignant mixed Mullerian tumor of the major omentum].

Malignant mixed Müllerian tumours (MMMT) are tumours of the female genital tract which rarely occur in extragenital sites. We report a case of a 46-year-old female with MMMT with primary occurrence in the greater omentum. Only 19 cases of primary extragenital manifestations of this tumour are described in literature. The clinical appearance, diagnosis, therapy, histological evaluation and histogenesis are discussed.
