Angular Stomatitis

Synonym: Perleche

Angular Stomatitis implies bilateral linear cracks at the angles of the mouth. It is a clinical entity which can be brought about by several causes, viz., malnutrition particularly deficiency of riboflavin, monilial infection, as a feature of seborrhoeic dermatitis, or as a complication brought on by an ill-fitting or sensitizing denture, or by pipe smoking. It is rarely seen as an evidence of secondary syphilis.

Clinically, it is seen as erythema and as a crack covered by a yellowish crust.

Prognosis of Angular Stomatitis

Perleche is usually a chronic condition. The prognosis depends upon the cause; unless the cause is corrected., the patient cannot be helped very much. So, in every case of angular stomatitis, instead of relying on vitamins, the attending physician should examine the patient thoroughly.

Treatment of Angular Stomatitis

The treatment consists in correcting the underlying cause, removing the crust with potassium permanganate lotion, and painting with 1% aqueous silver nitrate lotion, 1% gentian violet in 25% spirit or using Quadriderm (P), Kenacomb (P). Vitamins should be prescribed only when considered necessary.
