A rare case of mandibular metastasis in adenocarcinoma of lung

Mandibular metastasis may give an important clue to the diagnosis of an underlying occult malignancy. A 70-year-old female presented with painful swelling of right jaw for last 4 months and right-sided chest pain for last 1 month. CT scan thorax showed homogenous mass lesion in right lower lobe. FNAC from radiographically evident osteolytic lesion in mandible was suggestive of metastatic carcinoma. CT-guided trucut biopsy with immunohistochemistry from lung mass revealed primary adenocarcinoma of lung. Patient received palliative chemo-radiation for her advanced stage of cancer.
