A Clinical, Histopathological and Immunohistochemical Approach to the Bewildering Diagnosis of Keratoacanthoma

Keratoacanthoma (KA) is a comparatively common low-grade tumor that initiates in the pilo-sebaceous glands and pathologically mimics squamous cell carcinoma (SCC). Essentially, strong debates confirm classifying keratoacanthoma as a variant of invasive SCC. The clinical behavior of KA is hardly predictable and the differential diagnosis of keratoacanthoma and other conditions with keratoacantho...

A Giant Keratoacanthoma Treated with Surgical Excision

A keratoacanthoma is a rapidly growing cutaneous tumor that spontaneously involutes in most instances. A giant keratoacanthoma is a rare variant and are characterized by lesions larger than 20 mm in diameter. We report a 56-year-old man with a rapidly growing tumor of the right cheek, which was diagnosed as keratoacanthoma. The mass was excised completely under general anesthesia, followed by L...

Management of Keratoacanthoma

Keratoacanthoma is a tumor that is seen on a regular basis in a dermatologic and dermato-oncologic practice. The accurate management of this tumor is the biggest challenge. Many treatment options are available. In this review, we summarize the clinical and histological features of this not uncommon tumor. We review the current management with an emphasis on treatment.

Periocular keratoacanthoma: can we always rely on the clinical diagnosis?

AIM To present a series of patients with a clinical diagnosis of periocular keratoacanthoma and assess the incidence of histologically proven invasive squamous cell carcinoma (SCC). METHODS This retrospective case series included all patients with periocular tumours seen in the authors' unit between 1996 and 2004, and who were initially diagnosed with keratoacanthoma based on the clinical pre...
