A Case of Hypertrophic Osteoarthropathy Associated with Lung Metastasis of Parotid Gland Mucoepidermoid Carcinoma

Hypertrophic osteoarthropathy is a syndrome characterized by periosteal new bone formation, arthritis, and clubbing of the fingers and toes. The majority of cases occur secondarily to the conditions associated with pulmonary, cardiac, gastrointestinal disorders or other systemic diseases. There are many cases with malignancy worldwide. We report the first patient who had hypertrophic osteoarthropathy due to metastatic cancer after surgical removal for mucoepidermoid carcinoma of the parotid gland.
