RESUMO
The aesthetics for the male posterior torso remain a topic not fully studied in body contouring surgery, neither the lipoinjection of its muscles have been considered before. As a result, we carried out a retrospective cohort study including patients who underwent fat grafting of either the trapezius or the latissimus dorsi muscles as part of dynamic definition liposculpture (HD2). Methods: We performed cadaveric dissections to support the fat grafting technique for both the trapezius and the latissimus dorsi muscles. We also searched our records for patients who underwent fat grafting of these muscles in addition to HD2 from January 2016 to November 2021 at a single center in Bogotá, Colombia. Results: Thirty-five consecutive patients met the inclusion criteria. In total, 22 (63%) and 7 (20%) of 35 underwent fat grafting at the trapezius and the latissimus dorsi muscles alone, respectively, and 6 out of 35 (17%) of both. Mean age is 39 years (range = 22-63). All patients were men. No complications were recorded related to fat grafting. Almost all patients were satisfied with the procedure (97%). Follow-up period ranged from 2 to 48 months. Conclusions: Liposuction might not be enough to achieve the ideal V-shape of the men's back in some cases; hence, fat grafting of the power muscles becomes the best option. Recognition of the main neurovascular pedicle, proper preoperative markings, and a correct surgical technique ensure both the safety and the reproducibility of the technique.
RESUMO
La técnica de biopsia del ganglio centinela se ha desarrollado de manera tal que ha logrado reemplazar la disección linfática ganglionar electiva para la evaluación de metástasis nodales regionales en pacientes con melanoma cutáneo primario. Al ser un procedimiento mínimamente invasivo, es considerado como una herramienta con gran poder pronóstico y de estadiaje dado que es el único examen diagnóstico con tanto alta sensibilidad como especificidad permitiendo detectar enfermedad nodal clínicamente negativa debajo del umbral de cualquier otra técnica no patológica. Bajo este concepto una serie de guías terapéuticas y estudios que las respaldan se han desarrollado. En el presente trabajo se profundizará al respecto para ayudar a orientar al clínico y al cirujano a la hora de abordar este tipo de paciente.
Sentinel node biopsy technique has evolved in a way that it has managed to replace elective lymph node dissection for the evaluation of regional nodal metastases in patients with primary cutaneous melanoma. As a minimally invasive procedure, it is considered a great staging and prognostic tool, being the only diagnostic test with both high sensitivity and specificity that allows the detection of clinically negative nodal disease below the threshold of any other non pathological technique. Under this concept a number of therapeutic guidelines and research studies that support them have been developed. This review is intended to help guide the clinician and surgeon in the management of this type of patient.

Ante el reto diagnostico que presenta una neoplasia hepática que no es bien diferenciada, es este estudio se propone la utilización de un perfil de inmunohistoquímica que incluye citoqueratina (CK) 7, 19 y 20, as¡ como factor de transcripción tiroideo (TTF-1) para demostrar su eficacia en el diagnóstico diferencial de hepatocarcinomas, colangiocarcinomas y metástasis de adenocarcinoma y de ese modo facilitar los diagnóstico en la práctica diaria...
