Introduction: basosquamous cell carcinoma is a rare and poor prognosis histological type, that presents intermediate clinical and histological features between squamous and basal cell carcinoma. The diagnosis is made by biopsy, and the treatment is primarily surgical. Objective: determine epidemiological and clinical characteristics of cases of diagnosed basosquamous cell carcinomas, at Dr. Hernán Henríquez Aravena Hospital of Temuco, during the period 2003-2007 and proceed to compare the results with the literature. Materials and Methods: a retrospective review including all individuals with histological confirmation of basosquamous carcinoma, between 2003 and 2007 at Dr. Hernán Henríquez Aravena Hospital of Temuco. Were considered epidemiological variables of sex, age at diagnosis and mapuche surname, and clinical variables of location of the lesion, presentación (single or multiple) and the clinical-pathologic correlation. Results: 36 cases were found, 52.8% male, the average age at diagnosis was 74.6 years. 5.6% had a mapuche surname. 80.6% occurred in the head and neck. In the 63.9% of the cases, the clinical diagnosis based on the morphology of the lesion was basal cell carcinoma. We did not found clinical-pathologic correlation in any case. Discussion: our results maintain the trend recorded in the literature in relation to sex distribution, age of presentation and location. We did not found works about characteristics of this disease in mapuche population. The macroscopic diagnosis leads to confusion, so the diagnosis it has to be histological in every case.
