Keratoacanthoma is a benign neoplasm that develops as a protruding mass especially on the central part of face, We experienced a case of keratoacanthoma that developed on the nasal vestibule after the eradication of verruca vulgaris on the same site by surgical intervention 3 months before. We treated it with total excision and skin graft.

Keratoacanthoma is a rapidly growing tumor that has the tendency of spontaneous involution but it may persist for some times, continue to enlarge and may become invasive and destructive. Many modalities are available for the treatment of keratoacanthoma. Although excisional surgery is the treatment of choice, this can result in functional and cosmetic defects when large or strategically located lesions are treated. An effective nonsurgical treatment would be desirable in such cases. We report two cases with unusually large or facial keratoacanthoma treated with intralesional methotrexate. One case showed complete resolution over 6 injections and the other after 2 injections. We suggest that intralesional injection of methotrexate is a simple, effective, safe and inexpensive method for the treatment of large keratoacanthoma.

Keratoacanthoma is the epidermal tumor characterized by the benign course such as rapid growth and spontaneous resolution. Rarely keratoacanthoma invades adjacent structures. Therefore, controversies have arisen about the biologic behavior whether keratoacanthoma is a benign tumor or a variant of low grade cutaneous squamous cell carcinoma. We report a case of the recurred keratoacanthoma at the nasal vestibule treated with the surgical excision and the reconstruction by local bilobed rotation flap in a 54-year old female whose final pathology was confirmed as well differentiated squamous cell carcinoma.

Keratoacanthoma is a not uncommon skin tumor characterized by rapid growth of a smooth dome-shaped nodule with a central plug of keratin, usually followed by spontaneous involution. Because the tumor leaves a nunsightly scar, this is one of the reasons why these lesions should be treated. Excision is desirable if the diagnosis is in doubt. But surgical removal may be difficult, alternative treatment approaches should be considered. We report two cases of keratocathoma successfully treated by intralesional injection of 5-fluorouracil.

Keratoacanthoma is a rapidly growing tumor that histologically resembles squamous cell carcinoma. Surgical excision is a desirable therapeutic option, but several other treatment modalities are available. We report on two cases of keratoacanthoma that were treated with imiquimod 5% cream. Imiquimod was applied daily for the first 6 or 7 days, and then reduced to alternate days according to the tolerance and erythema severity of the patient. In both patients, the tumors fully regressed after five weeks of treatment.

Cutaneous horn is the clinical description of a hyperproliferation of compact keratin in response to a wide array of underlying benign and malignant pathologic changes. We report here on a case of cutaneous horn that originated from keratoacanthoma in a 76-year-old woman. Grossly, a 2.5x0.7 cm sized yellow-white colored scaly fungating mass from an erythematous nodule was observed on the right temporal area. Histopathologically, it was reported as keratoacanthoma with cutaneous horn. The lesion was totally excised after the diagnosis.
