Abordaje quirúrgico en un paciente con carcinoma epidermoide de células basaloides en cavidad nasal con invasión al cerebro

Introduction: One of the greatest challenges in oncological surgery is to individualize the management of each patient. Remembering that each patient will have individual characteristics, pathologies and unique history, which makes the therapeutic approach more complex. Case presentation: This is a 49-year-old female patient with 3-month onset of symptoms, with increased volume in the right periorbital region, intense headache in the occipital and frontal regions, loss of visual acuity in the right eye. Imaging studies are performed, finding an occupying lesion in the ethmoid cells, frontal and sphenoid sinuses, so a biopsy of the lesion is performed with a pathology report of squamous cell carcinoma of basaloid cells, and the decision is made to perform a combined surgical treatment, performing a frontal approach and endoscopic transnasal approach. Conclusions: In the literature review, a small number of cases of patients with squamous cell carcinoma of basaloid cells in the nasal cavity with infiltration to the brain have been reported, so the treatment is not yet standardized, however multidisciplinary treatment is the basis for success and patient prognosis.
