Use of Intraoperative Indocyanine Green Videoangiography to Guide Cutaneous Angiosarcoma Excision.

Complete excision of cutaneous angiosarcoma, which is a rare, vascular, and aggressive tumor, is challenging. Its multifocal nature and propensity for lateral spread make the gross assessment of surgical margins difficult. Neither the use of frozen section analysis nor Mohs surgery consistently improves the probability of margin-free excision. Recent studies have advocated the use of indocyanine green to evaluate the vascular system perioperatively. We describe the intraoperative use of indocyanine green to help define the excision margin of a locally extensive scalp angiosarcoma in an elderly man.

One-stage Integra reconstruction in head and neck defects.

BACKGROUND: Integra dermal regeneration template - a two-stage, tissue-engineered, artificial skin - was introduced in the UK in May 1996. There were no restrictions on clinical application and a series of applications in reconstructive surgery were undertaken. One case involved a Caucasian lady with a nose tip basal cell carcinoma (BCC) who had a single-stage reconstruction. The 6-year follow-up was remarkable as it showed a scarless repair. OBJECTIVE: We undertook a clinical evaluation to explore the outcome of one-stage Integra reconstruction in a selected series of Chinese patients. METHODS: Ten patients (five male and five female; age range: 54-86 years) with complicated or atypical cutaneous lesions involving the head and neck were treated in an outpatient setting. RESULTS: Pathology revealed eight BCCs, one squamous cell carcinoma (SCC) and one seborrhoeic keratosis. Healing took place either by wound contraction alone or in conjunction with re-epithelialisation. All wounds were fully healed within 6 weeks. Follow-up ranged from 18 to 30 months, and there has been no recurrence of the malignant lesions. CONCLUSION: In selected cases, one-stage reconstruction using Integra can reduce operating time with no delay for frozen section, flap raising or graft harvesting. More immediate postoperative care is needed, but the long-term aesthetic results are uniformly acceptable.

Extramammary Paget's disease in Chinese males: a 21-year experience.

BACKGROUND: Extramammary Paget's disease (EMPD) is a rare disease in Chinese males. Our objectives were to examine the results of our experience, to correlate them with the published literature, and thus to formulate improved management guidelines. METHODS: This was a retrospective analysis of all male patients with EMPD treated at our institution. We reviewed the patients and their case notes for data such as presenting symptoms, delay to diagnosis, incidence of concurrent malignancies, treatments given, and a variety of outcome measures, including the number of patients with recurrent or residual disease. RESULTS: The overall recurrence rate was 35%. The risk of recurrence was reduced if intraoperative frozen section analysis was used (25%) compared to simple wide local excision (60%). Wide local excision failed to excise the disease completely in 38%. There were no associated internal malignancies and no disease-related deaths in our sample. CONCLUSIONS: We recommend intraoperative frozen sections to reduce the risk of incomplete resection and to reduce the rate of recurrence. In our population, screening for internal malignancies can be restricted to select patients, e.g., those with perianal disease, those with invasive disease, and young patients.
