Abstract
Introduction: Skin cancer is the second most common neoplasm in the Guayaquil population. It occurs predominantly in areas exposed to sunlight. The most frequent types are basal cell carcinoma and squamous cell carcinoma. The technique of micrographic surgery of Mohs despite being described several decades ago continues in force in the treatment of this type of neoplasms. The aim
of the study is to present a series of cases submitted to this surgery.
Methods: The present observational study was carried out in the National Oncological Institute "Dr. Juan Tanca Marengo "Solca-Guayaquil. Clinical histories of the periods between January 2015 and December 2017 were reviewed. Cases of patients with malignant neoplasms of the skin were selected, who underwent Mohs micrographic surgery. The type of sampling was non-probabilistic of convenience. The variables studied were sex, age, anatomopathological diagnosis, location of the lesions and recurrences. Descriptive statistics is used.
Results: 153 patients with a mean age of 71.9 ± 12 years were analyzed, the most frequent histological type was nodular basal cell carcinoma with 115 cases (75.16%). The lesions were located predominantly on the nasal dorsum, 40 cases (26.14%) and in the nasal ala, 17 cases (11.11%). At the time of surgery, more than half of the lesions were in stage 1 (58.1%). The coverage technique most frequently used was the rotation flap (49%). There were no cases of recurrence after Mohs micrographic surgery in the patients studied.
Conclusion: The epidemiological characteristics of skin cancer in the population of Guayaquil are similar to those reported in international literature. Patients undergoing Mohs micrographic surgery did not present recurrence in this report.
