ABSTRACT Atypical fibroxanthoma (AFX) typically occurs on the head and neck of elderly white men. Usually considered a malignancy, it is treated with wide local excision (WLE) or total margin control using Mohs micrographic surgery (MMS).
To determine the most appropriate treatment for this tumor based on a review of cases treated at Mayo Clinic.
We reviewed the medical records of patients with AFX treated at Mayo Clinic from 1980 to 2004.
We identified 91 patients with 93 tumors. Treatment information was available for 88 tumors (59 treated with MMS, 23 with WLE, and 6 by other means). There were no recurrences in the patients treated with MMS, with a median follow-up of 4.5 years (range 1.0-16.1 years). Two patients treated with WLE had single recurrences, with a median follow-up of 8.7 years (range 1.5-26.3 years).
Total microscopic margin control using MMS was the most effective means of treating AFX.

    ABSTRACT: Atypical fibroxanthoma (AFX) is an ultraviolet radiation-associated dermal neoplasm. To address the clinicopathologic and molecular features of this particular neoplasm. The author conducted a literature review using PubMed searching for articles relating to AFX. AFX usually appears as a rapidly growing nodular or nodulo-ulcerative lesion. It occurs on sun-exposed skin of elderly peoples. AFX may be composed predominantly of pleomorphic, spindle, epithelioid cells, or admixture of these cells. The differential diagnosis of AFX includes pleomorphic dermal sarcoma, squamous cell carcinoma, malignant melanoma and leiomyosarcoma. Several observations favor a mesenchymal origin for AFX. These reviews address the clinicopathologic features, molecular pathology, prognosis and treatment of this neoplasm.

    ABSTRACT: Mohs micrographic surgery (MMS) is a technique that allows examination of all surgical margins of the excised skin lesion. It is a well-established treatment for high-risk basal and squamous cell carcinomas yielding unsurpassed cure rates. MMS is also employed to treat melanomas and certain uncommon tumors such as dermatofibrosarcoma protuberans, microcystic adnexal carcinoma, Merkel cell carcinoma, sebaceous carcinoma, desmoplastic trichoepithelioma, extramammary Paget’s disease and atypical fibroxanthoma. This article will review the evidence for MMS in the management of these less common indications.

    ABSTRACT: An article titled "Current issues in dermatologic office-based surgery" was published in the JAAD in October 1999 (volume 41, issue 4, pp. 624-634). The article was developed by the Joint American Academy of Dermatology/American Society for Dermatologic Surgery Liaison Committee. A number of subjects were addressed in the article including surgical training program requirements for dermatology residents and selected advances in dermatologic surgery that had been pioneered by dermatologists. The article concluded with sections on credentialing, privileging, and accreditation of office-based surgical facilities. Much has changed since 1999, including more stringent requirements for surgical training during dermatology residency, and the establishment of 57 accredited Procedural Dermatology Fellowship Training Programs. All of these changes have been overseen and approved by the Residency Review Committee for Dermatology and the Accreditation Committee for Graduate Medical Education. The fertile academic environment of academic training programs with interaction between established dermatologic surgeons and fellows, as well as the inquisitive nature of many of our colleagues, has led to the numerous major advances in dermatologic surgery, which are described herein. Dermatologists have been responsible for multiple advances and refinements in dermatologic office-based surgery over many decades. Dermatologists receive extensive training in office-based surgical procedures during residency, fellowships, and continuing medical education courses. The last update on this subject appeared in the Journal in 1999. This article will document the multitude of advances that have occurred since 1999.
