ABSTRACT
Squamous cell carcinomas are the most common cancer of the lower lip. In most cases, the tumor is small and occupies less than a third of the lower lip, so the defect created can be closed with a primary suture without altering the esthetics and function of the lower lip. However, there is a percentage of large tumors that affect more than two thirds of the lower lip, in which the primary suture is insufficient to correct the defect created by resection of the tumor. Therefore, these cases require more complex reconstructions using facial locoregional flaps. Hence, in this article, the authors present a total reconstruction of the lower lip with a bilateral subcutaneous pedicled nasolabial island flap after complete resection of a squamous cell carcinoma with involvement of the entire lower lip.
ABSTRACT
BACKGROUND: Carcinoma ex-pleomorphic adenoma (Ca ex-PA) comprises 0.5% of head and neck neoplasms. Transoral robotic surgery (TORS) is an approach being used to treat a variety of benign and malignant head and neck neoplasms. Recently, this technique has gained popularity as an alternative for parapharyngeal space (PPS) tumor resection. To our knowledge, this is the first case of Ca ex-PA managed successfully by TORS of the PPS. CASE: Fifty-nine-year-old male with incidental mass in PPS, initial diagnosis of pleomorphic adenoma, who underwent transoral robotic resection. The histopathology diagnosis with minimally invasive Ca ex-PA findings and malignant component of high-grade epithelial/myoepithelial carcinoma and salivary duct carcinoma. Patient discharged on the fifth post-operative day without complications. CONCLUSION: Based on our findings, TORS may be a safe procedure to remove selected Ca ex-PA from the PPS; however, further research is needed.

El tumor tricolémico maligno de cabeza y cuero cabelludo es un tumor que se origina de la vaina radicular externa del folículo piloso, fue descrito por primera vez por Wilson-Jones en 1966 como "proliferación de quiste epidermoide'', su frecuencia de presentación es rara y se encuentran pocos casos reportados en la literatura. Es un tipo de tumor que tiene un comportamiento biológicamente benigno aunque puede presentar transformación maligna y puede confundirse con carcinoma escamocelular, por lo que es importante la experiencia de clínico y el patólogo es este tipo de casos. A continuación se presenta un caso clínico en cuero cabelludo y cuello del instituto nacional de cancerología y la forma de abordaje quirúrgico
Malignant Trichilemmal tumor of neck and scalp are tumors that originate from the outer root sheath of the hair follicle, was first described by Wilson-Jones in 1966 as "proliferation of epidermoid cyst", its frequency is extremely rare and there are very few cases reported, is considered biologically benign but may present malignant transformation can be confused with squamous cell carcinoma, is important the experience of clinical and pathologist is this type of case. A clinical case is presented in scalp and the National Cancer Institute and the form of surgical approach neck.

En la cirugía mínimamente invasiva del cuello poco se ha evolucionado considerando que usualmente se acompaña de disecciones extensas, dolorosas y prolongadas en tiempo operatorio. Este tipo de cirugía que denominamos como: "cirugía en mínimos espacios del cuello", es una línea de trabajo del grupo y a finales del 2015 se inició el programa de cirugía endoscópica de cuello. En junio del 2016 intervinimos una paciente joven con carcinoma papilar de tiroides, utilizando la Tiroidectomía Axilar Endoscópica Video Asistida (TAEVA) con equipo Endoeye Flex 3 D. Se observaron claras ventajas al usarlo, como alta resolución visual, buena profundidad de campo y versatilidad derivada de la flexibilidad de la cámara que evitó el intercambio de lentes rígidos de 0°,30° y70°, lo que acortó el tiempo operatorio. Hasta donde se tiene conocimiento es el primer caso de TAEVA 3 D publicado.
Little has evolved in minimally invasive neck surgery, considering that this is usually accompanied by extensive, painful, and prolonged operative time in dissections. This type of surgery is called "Minimum space surgery of the neck", and is a line of work of our group. For this reason, an endoscopic neck surgery program was started in 2015. A young patient with papillary thyroid carcinoma was intervened in June 2016 using Endoscopic Axillary Video assisted thyroidectomy (TAEVA) with equipment EndoEYE Flex 3 D. Clear advantages were observed including high visual resolution, good depth of field, versatility derived from the flexibility of the camera that avoided the exchange of inflexible 0°,30°, and 70° lenses, and shortening the operating time. To our knowledge, it is the first case of 3 D TAEVA published.
