Acne Varioliformis

Acne Varioliformis

(Synonyms: Acne Frontalis; Acne Rodens; Acne Necrotica; Lupoid Acne; Necrotic Granuloma.)

Describe acne varioliformis.

Acne varioliformis is characterized by lesions of a moderately superficial papulo-pustular type, which in disappearing leave slight or well-marked pit-like scars. The forehead and scalp are the favorite sites, but they may also occur elsewhere. The eruption is rather scanty as a rule, consisting usually of ten to thirty lesions. They begin as small maculo-papules, as papules, or as minute nodules in or on the skin, and gradually become small pea-sized, with a tendency to slight vesiculation or pustulation at the central part. The lesion is sluggish in its course, drying to a thin crust, which finally falls off, leaving a depressed variola-like scar. New lesions arise from time to time, and the disease thus continues almost indefinitely. There may or may not be itching. In what appears to be a variety of this disease, known usually as acne urticata, there is considerable itching just at the time the lesion is appearing. The malady is not frequent, but occurs in both sexes, usually in those between the ages of twenty and fifty. It seems probable that the eruption is parasitic in origin.

The maladies variously known as hydradenitis suppurativa, acnitis, spiradenitis, folliclis, granuloma necroticum, etc., in which the lesions, primarily at least, are somewhat deeper seated, sluggish in their course, and followed by scarring, could be also included under this head.

Give the prognosis and treatment.

The disease is rebellious and tends to recur. The most efficient applications are those of sulphur and resorcin, the same as prescribed in ordinary acne.
