Oral and maxillofacial pain as the first sign of metastasis of an occult primary tumour: A fifteen-year retrospective study

Figure 1 Five types of metastatic adenocarcinoma of the jaw. A: Osteolytic type. Axial spiral-computed tomography (SCT) with bone window showed decreased radiodensity of the lesion (arrow) with a permeative margin. The multi-layered periosteal reaction was observed on the buccal and lingual sides of the left mandibular ramus; B: Osteolytic type. Axial SCT with soft-tissue window showed a confined soft tissue mass (arrow) at the lingual side of the left mandibular ramus; C: Osteoblastic type. Axial SCT with bone window showed increased radiodensity of the lesion (arrow) with a sclerotic margin; D: Mixed type. Oblique sagittal cone beam CT showed both osteolytic and osteoblastic lesions (arrow) with a moth-eaten margin, and an “ivory” pattern of osseous tumour matrix was centred in the left mandibular at the location of mental foramen; E: Cystic type. Partial panorama reconstruction radiograph showed homogeneous radiodensity of the lesion (arrow) in the anterior part of the maxilla with a geographic margin. Teeth displacement and root resorption were observed; F: Alveolar bone resorption type. Axial SCT with bone window showed bone destruction was confined to the alveolar bone with a geographic margin. A soft tissue component was at the buccal side.
