OBJECTIVE: To determine the ability of fluorodeoxyglucose F 18 positron emission tomography (FDG-PET) to image basal cell carcinoma (BCC). DESIGN: Case series study. SETTING: Mohs surgery practice in a tertiary university hospital. PATIENTS: Six patients with BCC larger than 1.0 cm of the head and neck region were identified. RESULTS: Patients were imaged using FDG-PET before surgery. In 3 patients, PET imaging correlated well with the size and extent of the soft tissue invasion. Histologically, all 3 tumors were of the nodular subtype. The remaining 3 patients failed to demonstrate identifiable tumor activity on PET. Two of these 3 tumors were of the infiltrative histologic subtype, and 1 was of the nodular subtype. Perineural spread was detected by tissue biopsy in 1 infiltrative tumor, but not by FDG-PET imaging. CONCLUSIONS: In our study, FDG-PET imaging was able to image and identify BCC in the head and neck region in 3 of 6 patients. In some cases, anatomic accuracy and the extent of soft tissue invasion were observed. The histologic subtype of the BCC appears to affect the ability of FDG-PET detection, with the nodular histologic subtype more likely to test positive on PET. This is a preliminary study, and future investigation is needed to evaluate the role of PET imaging in the management of patients with BCC.

The periocular area is a complex region with free margins and cosmetic landmarks that are easily distorted during surgical reconstruction. Repair of surgical defects should maintain both periorbital function and aesthetics. In this article we discuss the basic methods of closure (side-to-side closure, flaps, grafts and second intent healing) as they apply to the periocular area and suggest an algorhythmic approach to reconstruction by aesthetic subunit. Pertinent regional anatomy and perioperative management are also reviewed.
The optimal extent-of-disease evaluation for patients with clinically suspected melanoma recurrence is not known. The available modalities are numerous and many are expensive. We documented the extent of work-up carried out by plastic surgeons when their patients with melanoma develop clinical recurrence. A custom-designed questionnaire was mailed to a random sample (n=3,032) of the 4,320 members of the American Society of Plastic and Reconstructive Surgeons (ASPRS). Subjects were asked which specific laboratory tests and imaging studies they would order for a patient with initial T2N0M0 disease treated with curative intent who later presented with either regional nodal metastases or pulmonary metastases. We measured the variability in practice patterns among surgeons and estimated the effects of physician age, U.S. census region, health maintenance organization (HMO) penetration rates, and type of recurrence (regional versus systemic) on work-up intensity. Of the 1,142 questionnaires completed (38%), 395 (35%) were evaluable. Non-evaluability was usually due to lack of melanoma patient follow-up in surgeons' practices. Lesion biopsy, chest X-ray, complete blood count, liver function tests, and computed tomography were frequently used, but there was no consensus for most modalities. More tests, particularly computed tomography, were utilized for evaluating systemic recurrence than for regional recurrence (p<0.05). The intensity of work-up differed significantly (p<0.05) by surgeon age for three diagnostic tests but not by U.S. census region or HMO penetration rate. This is the first empirical data on this subject from a large sample of an international society of highly credentialed experts. The lack of consensus for most tests in current practice is presumably due to multiple factors, including the lack of evidence supporting any particular strategy.
Basal cell carcinoma (BCC) is the most common cutaneous skin malignancy. BCC generally has a clinical course characterized by slow growth, minimal soft tissue invasiveness, and a high cure rate. Occasionally, however, BCC behaves aggressively with deep invasion, recurrence, and potential regional and distant metastasis. Several factors, including tumor size, duration, histology, and perineural spread, have been postulated as markers of the aggressive BCC phenotype. It is undetermined whether intrinsic biological factors within certain subsets of BCC predispose these tumors toward an inherently aggressive behavior, or whether any BCC with inadequate early management may assume this phenotype. Review of the pertinent literature on this topic suggests that both intrinsic biological factors and extrinsic management factors play a role in the development and progression of aggressive BCC.
