Colgajo bilobulado en epiteliomas basocelulares nasales / Repair of nasal defects secondary to excision of basal-cell epitheliomas

Background: The repair of defects secondary to excision of basal-cell epitheliomas can be a challenge. Aim: To report the experience with the repair of nasal defects using bilobed flaps. Material and Methods: Review of medical records of 10 patients in whom a basal-cell epithelioma was excised and the nasal defect was repaired using a bilobed flap. Results: In all patients, the flap allowed the repair of the defect using the own patient nasal skin, without complications. Conclusions: The bilobed flap is an excellent technique for the repair of medium size nasal defects secondary to excision of basal-cell epitheliomas.

Objetivo: La nariz es el área corporal con mayor incidencia de epiteliomas basocelulares y la reparación de los defectos secundarios a su resección, puede ser un desafío. El objetivo es presentar nuestra experiencia en la reparación de defectos nasales, empleando colgajos bilobulados. Material y Método: Se realizó una revisión retrospectiva de 10 pacientes con epiteliomas basocelulares nasales en que empleamos este colgajo. Resultados: En todos los pacientes el colgajo bilobulado permitió la reparación del defecto, con la propia piel nasal y sin complicaciones. Conclusiones: Consideramos al colgajo bilobulado como una excelente técnica para la reparación de defectos nasales de mediano tamaño, secundarios a la resección de epiteliomas basocelulares.

Linfoma primario del sistema nervioso central en una paciente inmunocompetente: Caso clínico / Primary central nervous system lymphoma in an immunocompetent patient: Report of one case

Primary central nervous system lymphoma (PCNSL) is a rare tumor. It occurs mainly in people aged 50 year-old or older and is more common among men. Immunodeficiency is the only established risk factor for PCNSL. We report a 35 year-old, immunocompetent woman who presented with a two weeks history of persistent headache. Computed tomography (CT) and magnetic resonance imaging (MRI) showed an expansive lesion in the right thalamus area. Immunohistochemical studies were consistent with the diagnosis of a difuse large B-cell non-Hodgkin 's lymphoma. The patient was treated with chemotherapy and whole brain radiotherapy, achieving complete remission of the tumor. This case is ilustrative of PCNSL and contributes to update its diagnosis, management and prognosis.
