Answer

Diagnosis of necrotizing fasciitis can be difficult and requires a high degree of suspicion. In many cases of necrotizing fasciitis, antecedent trauma or surgery can be identified. Surprisingly, the initial lesion is often trivial, such as an insect bite, minor abrasion, boil, or injection site. Idiopathic cases are not uncommon, however.
