Background: Non-melanoma skin cancer includes basal cell carcinoma and squamous cell carcinoma (SCC). Basal cell carcinoma is the most common and least aggressive but in a low percentage of cases, despite appropriate wide surgical margins, it can be aggressive, producing local invasion, recurrences and distance metastasis. SCC has a more aggressive behaviour invading first the skin, the lymph nodes and less frequently produces distance metastasis OBJECTIVE: To identify the characteristics of recurrent SCC and frequency of new SCC 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., Materials and Method: We reviewed clinical records from the last 10 years, and included those with a diagnosis of SCC., Results: One hundred and fourteen tumours in 103 patients were included. The mean new tumour diagnosis was 32.2 per year; there were 46.6% men and 53.4% women. Age range 19-91, with mean 71.94 years (SD=13.34). The evolution time was from 1-112 months (mean=12 months, SD=2.65). The most affected site was the cheek. In addition, an invasive tumour was reported in 54% in the histopathological study. At 10-year follow-up we found a second SCC in 14 patients and only 4 recurrences, between the 1st and 4th year and 3were treated with delayed closure until margins were tumour-free., Conclusion: In this study we demonstrated that delayed closure technique is easy and adaptable in our population in the treatment of SCC, achieving good results with very low recurrences at 10- year follow -up., (Copyright © 2016 Academia Mexicana de Cirugía A.C.
