Unusual bony metastasis in a case of oesophageal carcinoma<

Cancer oesophagus is the ninth most common cancer and is the sixth most common cause of cancer related deaths in the world. It usually presents in advanced stage with loco-regional node and visceral involvement. Bone metastasis is uncommon. Here we are reporting a case of a 55-year-old male, with progressive dysphagia to solids and semisolids for 1 year. Rigid endoscope guided biopsy confirmed that histology was well differentiated squamous cell carcinoma. Computed Tomography (CT) scan of the neck and thorax revealed oesophageal malignancy with enlarged neck lymph nodes on left side and metastasis in left greater wing of sphenoid, part of temporal bone and lateral wall of the orbit and abutting the left lateral rectus muscle. Literature search revealed that bony metastases are very infrequent and small bones are usually spared. This case is noticeable for rarity in terms of metastatising to unusual sites.
