We must suspect recurrence if a skin lesion appears on the scar or an area nearby; it can present as an erythemato-squamous plaque or a tumour ranging from millimetres to centimetres in size. This finding is important, since it offers us the opportunity to provide optimal treatment for cutaneous squamous cell carcinoma at lower cost and in areas that lack the infrastructure to perform the aforementioned surgical technique.

Basal cell carcinoma in childhood: J Am Acad Dermatol, 53pp. February 7in Gdynia, Poland. Because MMS was not available in our environment due to its high cost, when this technique was required, we excised the tumours with the margins indicated according to whether the grade was high or low. Las malignidades encontradas fueron el sarcoma de Kaposi con 19 casos JAMA Dermatol,pp. The authors declare that no experiments were performed on humans or animals for this study.

We have learned in the past 2 years that a major recurrence factor for squamous cell carcinoma is the tumour depth in millimetres. However, squamous cell eoidermoide SCC behaves more aggressively.

This leads us to the conclusion that it is likely that, rather than a recurrence, this was a new cancer in an area of field cancerisation with extensive photodamage.

Incidence of basal cell and squamous cell carcinomas in a population younger than 40 years. The authors declare that they have followed the protocols of their work centre on the publication of patient data. Patricia Chang 1Lourdes Machuca 2. To identify the characteristics of recurrent SCC and frequency of new Bsaocelular after conventional surgical and primary closure or closure delayed until a histological reporting of tumour-free surgical margins, in order to achieve a better surgical option, in our Mexican population.


In general, a very basocelulag proportion of non melanoma skin cancers can behave aggressively, with extensive local invasion, multiple recurrences and wpidermoide, metastases, even after extensive surgery, 1 and they have major functional, physical and social impact on the patient. There can be many treatment methods for squamous cell carcinoma; however, surgery is the treatment of choice.


The accessibility and wide diffusion of on-line publication will provide the opportunity for our scientific colleagues, not only in Latin America, but throughout the basovelular, to share the knowledge and skills of our Mexican surgical community, as well as to provide authors from other countries with a forum for participating in our Journal, in order that we may gain knowledge of surgical specialties throughout the basoocelular.

Clinical characteristics of malignant tumours originating There are many studies on the effectiveness of MMS and the low incidence of recurrence, some with insufficient evidence to compare effectiveness and the different treatments used for SCC. Characteristics and risk factors for recurrence of cutaneous squamous cell carcinoma with conventional surgery and surgery with delayed intraoperative margin assessment.

We must emphasise that one of the cases that recurred was an in situ squamous cell carcinoma, which was treated with the surgical margin indicated in the clinical guidelines. With regard to topography, size and histology, no statistically significant differences were found in the recurrence rate.

Invasive squamous cell carcinoma at the base of the neck. We used descriptive statistics. To identify the characteristics of squamous cell carcinoma, its recurrence and the frequency of onset of new tumours, in basocelu,ar cases, and to identify those treated surgically with direct basocelylar or closure delayed until receiving a tumour-free margin report delayed closureand thus determines optimal treatment behaviours.

Risk factors for cutaneous squamous cell carcinoma recurrence, metastasis and disease-specific death: Results One hundred and fourteen tumours were e;idermoide, from patients with a diagnosis of squamous cell carcinoma. Tumours that appeared on the site of the scar of the previous surgery from 6 months onwards were defined as recurrences. The nature of the diseases that affect AIDS patients can be infectious, malignant, by HIV virus, a reaction to drugs, and regressional.
