Case of the day – hyperplasia of the gingiva due to amlodipine medication for hypertension. The pseudo-tumorous enlargement of the gums is a rare but an established side-effect of calcium channel blockers amlodipine often used to control hypertension in ambulatory care. The patient had been taking this drug over the last 5 years, neither she nor the physician considered this drug to be the cause of the gum enlargment. The key learning point here is to sensitize the treating physician to this established albeit rare side-effect. This manifestation is reversed after stopping amlodipine.
