In the minor form, which is more common, ulcers are 2-10 mm in size and multiple with a central necrotic area and a red halo. They heal in about 2 weeks without leaving a scar. In the major form, ulcer is very big, 2-4 cm in size and heals with a scar but is soon followed by another ulcer. Aetiology of aphthous ulcers: Etiology is unknown.
