Subunguales Keratoakanthom

Abstract: Subungual keratoacanthomas (SKA) differ in clinical presentation, biological behaviour and the therapy needed from keratoacanthomas in other localizations. Against the backdrop of two personal observations and a review of the literature, the authors describe clinical and histological features and also the differential diagnosis and therapy and this rare benign neoplasm. Patients present with a rapidly growing, painful subungual mass, which causes destruction of the underlying bone and usually does not regress … Show more

“…Solitary KAs respond well to surgical excision and, if they become too large or invade other structures, may require aggressive procedures. Subungual KAs invading the phalanges may require digit amputation 87 . Mohs’ micrographic surgery may be the treatment of choice for KAs located in sensitive areas, such as the face, as it is tissue sparing 88 .…”

“…Erosions of the underlying distal phalanx usually heal spontaneously but recurrence after subtotal excision may require distal phalangeal amputation. 20 Bowen's Disease (SCC In Situ) Bowen's disease occurs on the dorsum of the hand, the fingers, and less commonly the palms as an asymptomatic, erythematous, crusted, or scaly patch or plaque. 21,22 Bowen's disease of the nail may present with periungual hyperpigmentation, making it difficult to distinguish from subungual melanoma (see section on melanoma for further information on pseudo-Hutchinson's sign).…”

“…The lesion may give the initial appearance of a mycotic nail 14,28 with onychocryptosis 14 . Paronychia is also a common misdiagnosis when the periungual tissue is involved 4,8,30 . In fact, clinically, there are three main diagnoses of practical significance to consider.…”
