Four hundred fourteen primary cutaneous squamous cell carcinomas were treated by microscopically controlled excision. A five-year mortality-table adjusted cure rate of 93.3% was achieved. The following six parameters were analyzed for correlation with the local recurrence rate: sex, age, lesion diameter, history of previous therapy, anatomic site, and number of stages of Mohs' surgery required for treatment. Only the number of stages correlated significantly with the recurrence rate. However, subpopulations at high risk for recurrent disease could be identified. These consisted of male patients younger than 60 years of age, male patients requiring five or more stages of Mohs' surgery, and patients of either sex with carcinoma of the lower extremity. Modifications of microscopically controlled excision may be warranted in selected patients

In a consecutive series of 648 superficial spreading melanomas a significantly better 5-year disease-free survival rate was observed for patients whose primary tumors were 14 mm or less in diameter when compared with those 15 mm or larger in diameter. Other distinguishing features of the group of 'smaller' superficial spreading melanomas were that they occurred in younger patients; were of shorter durations; were more common in women; occurred disproportionately on the lower limbs; were less elevated; tended to be round in shape; were thinner (Breslow); penetrated less deeply (Clark levels); showed less histologic regression; and developed fewer metastases. Based on these findings it is recommended that educational programs be undertaken for the medical profession and for the public to promote early diagnosis and prompt treatment of superficial spreading melanomas when they are small in diameter and more often curable. A color atlas of 'small' melanomas is presented

The three basic types of medical-office computer systems have been described along with their basic advantages and disadvantages. A fourth option, that of keeping your current manual office system, may be a valid alternative. The next article of this series will discuss a method for evaluating the suitability of any computer system for your needs and will describe how to select the 'best' one for you

In this article, the potential benefits of an office computer system have been detailed. As computer costs and sizes decrease, and computing capabilities increase, even more benefits will be had in the future. Of course, not all of these benefits are applicable to all practices. Equally important to note are the many problems associated with installation and use of computer systems, and these must be taken into account before an intelligent decision can be made as to whether its acquisition would benefit your practice. Helping the physician to weigh the benefits of an office computer system against its costs and potential problems will be the subject of the next article in this series

Fourteen prognostic factors were examined in 79 patients with clinical Stage I melanoma greater than or equal to 3.65 mm in thickness. All nine patients with melanoma of the hands or feet died of melanoma. A Cox proportional hazards (multivariate) analysis of the remaining 70 patients showed that a combination of the following four variables best predicted bony or visceral metastases: 1) a nearly absent or minimal lymphocyte response at the base of the tumor, 2) histologic type other than superficial spreading melanoma, 3) location on the trunk, and 4) positive nodes or no initial node dissection. Ulceration and/or ulceration width were not useful in predicting outcome either singly or in combination with other variables. Patients with negative lymph nodes and primary tumors of the trunk, hands, and feet did not do better than patients with positive nodes at those sites. Conversely, non of 16 patients with negative lymph nodes and extremity melanomas (excluding the hands and feet) or head and neck melanomas developed visceral or bony metastases (i.e., five-year disease-free survival rate 100%)
