Métastase gingivale d’un sarcome phyllode du sein

Background. The metastasis of oral cavity is rare. We report a gingival metastasis in the course of low grade phyllode sarcoma of the breast which is usually little metastatic. Case-report. A 44 year old woman was operated two years ago for a phyllod sarcoma of the breast histologically confirmed. She presented for a mandibular exophytic tumour associated with haemorrhagic, necrotic, ulcerated and bulking gingivitis surrounding at the level of the maxillary and mandibular gingiva. The examination revealed multiple nodular lesions of the trunk and the scalp. The histological examination confirmed the diagnosis of cutaneous and gingival metastasis of the phyllod sarcoma of the breast. The evolution was rapidly fatal. Discussion. The gingival metastasis are rare tumours with a bad prognostic. Their diagnosis is based on clinical and histological arguments and must be made different from chronic gingivitis which can be associated.
