It begins with intense itching and pain, followed by the formation of deep coalescing vesicles. The process is associated with much tissue destruction and may be accompanied by systemic symptoms. A similar lesion may occur as a result of nail biting during the course of primary herpetic gingivostomatitis.

Purulent infection through a perionychial fold causing an abscess of the bulbous distal end of a finger.

felonParonychia, whitlow, run-around A purulent infection in the tight fascial plane adjacent to the terminal intraphalangeal joint of the fingers or toes, due to an open wound; as the inflammatory mass expands within the confined space, the vascular supply is compromised, predisposing the site to osteomyelitis, pulp necrosis and sloughing of tissue; the pain is very intense and seemingly disproportionate with the scant amount of swelling and erythema clinically evident Treatment Drainage by incision directly over the site of maximum swelling; the term has also been applied to a localized painful herpetic skin infection 'seeded' in an open abrasion by contact exposure.
A purulent infection or abscess involving the bulbous distal end of a finger.
