Dermatologists commonly treat acne, which affects 40 to 50 million Americans each year and about 85 percent of all patients at some point in their lives. However, sometimes acne isn t really acne. Many skin conditions have a clinical presentation similar to that of acne vulgaris but are distinct diseases. It is important for dermatologists to recognize that alternative diagnoses exist, particularly if a patient is not responding to traditional acne therapies. The patient may have a different disease altogether and respond to alternative treatments. §When Acne Isn t Really Acne: A Differential Diagnosis of Acneiform Eruptions in Dermatology is a practical, full-color guide to the differential diagnosis of acne vulgaris and the treatment of acne-like conditions. It is organized into sections by subtype of condition (e.g., infections, genetic syndromes, medication-caused) and includes a section of variants of acne that may be misdiagnosed. Within the sections, individual chapters discuss each variant of the condition and begin with a helpful bulleted summary of its defining clinical features. Extensive color clinical images appear throughout the book.§When Acne Isn t Really Acne covers acneiform diseases and their treatment in a concise yet comprehensive way for busy dermatologists.
