title: Human bite marks. Differential diagnosis.
abstract: Human bite marks are common findings in cases of fights among children, child abuse, sexual abuse, among institutionalized persons, and in a number of homicide cases. Human bites can mimic annular or arciform dermatoses. These are reviewed from both a clinical and histologic viewpoint. An example is presented of a 2 year-old girl with several annular lesions that were clinically mistaken for a dermatophyte infection. Antifungal medications were ineffective. After several days, a dermatologist identified the lesions as human bites. Physicians and other health care workers must be able to differentiate the clinical appearance of bite marks from other dermatologic diseases at an early stage so as to initiate proper therapy and counseling and, if indicated, a search for the perpetrator.
