Introduction. The objective of this study was to compare the short-term outcomes of laparoscopic gastrectomy in adults vs. older patients with locally advanced gastric cancer from a Western country cohort. Methods. Prospective cohort study in patients undergoing laparoscopic gastrectomy for locally advanced gastric cancer at the Hospital Universitario Erasmo Meoz, de Cúcuta, Colombia, between November 2014 and December 2018. Descriptive, group comparison and bivariate analysis was performed. Results. Of a total of 116 patients, 51 patients (44%) were 65 years or older and 63 patients (54%) were men. No statistically significant difference was found when comparing patients under 65 years of age with those 65 years of age or older. The median operating time was 240 minutes in both groups (p>0.05), the median macroscopic resection margins were 6 cm vs. 5 cm (p>0.05), the median number of lymph nodes dissected was 25 vs. 19 (p>0.05), the median number of positive lymph nodes was 4 vs. 3 (p>0.05), the median stay was 7 days in both groups (p>0.05). The overall rate of postoperative complications did not differ significantly between adults (7%) and older adults (11%) (p>0.05) and no significant differences were observed in the rates of minor (Clavien-Dindo grade II; 3-5% vs. 6-12%; p>0.05) and severe complications (Clavien-Dindo ≥ IIIa; 3-5% vs. 4-8%; p>0.05). Conclusions. No statistically differences were found in short-term outcomes between adult and older patients with locally advanced gastric cancer treated with laparoscopic gastrectomy. This technique is safe in the elderly. [ABSTRACT FROM AUTHOR]

Introduction: Liposarcoma of the vulva is extremely rare, it represents a diagnostic challenge for the gynecologist as well as the pathologist, there are few cases reported in the literature. We present a case of pleomorphic liposarcoma of the vulva, the first reported at the National Oncological Institute in Panama. Case report: This is a 52-year-old woman with a one-year history of a tumor on the right labia majora of the vulva, with accelerated growth in recent months associated with ulceration. The biopsy reported high-grade malignant mesenchymal neoplasia. She was taken After surgery, hemivulvectomy and flap reconstruction, the resection margins were negative. Postoperative evolution without adverse events. Conclusions: Pleomorphic liposarcoma of the vulva is an extremely rare entity; biopsy of the vulvar tumor is crucial for planning surgery, the treatment of choice in most cases. Adjuvant treatment is individualized and follow-up could be close. [ABSTRACT FROM AUTHOR]

BACKGROUND: Epithelioid hemangioendothelioma is a rare vascular tumor, symptoms by endothelial and dendritic cells with an epithelioid appearance. At the bone level, it represents <1% of primary tumors, it appears mainly in long bones of the lower extremities, followed by vertebral bodies, bones of the hands and feet. CLINICAL CASE: 56-year-old male patient, with forced inversion of the right foot of five months of evolution and progressive increase in volume in the fifth joint of the same foot. Due to the radiological results, it was decided to obtain a biopsy of the fifth metatarsal, but in the surgical act it was decided to carry out a complete resection of the lesion. Among the histopathological findings, the following stand out: a lesion consisting of a neoplasm with a growth pattern in nests, of variable size and trabeculae, cells with an epithelioid appearance, mild pleomorphism and eosinophilic cytoplasm, formation of cytoplasmic lights and prominent nucleolus; neoformation vessels and thrombi. Extensive ischemic necrosis was identified. Immunohistochemistry reported positive CD31 and Factor VIII. The diagnosis of epithelioid hemangioendothelioma was established. CONCLUSION: Although there are no established treatment guidelines for this neoplasm, traditionally surgical resection with wide margins has been chosen, reserving radiotherapy and chemotherapy for patients with multiple tumors or those with difficult access for the surgical procedure.

BACKGROUND: Primary renal lymphoma is an exceptionally rare disease with only 100 reported cases in the literature. In contrast, renal clear cell carcinoma represents the seventh malignant neoplasm in patients under 75 years old and affects both sexes equally. The coexistence and diagnosis of them as synchronous ipsilateral primary disease is considered extraordinary rare. CLINICAL CASE: A 65-year-old male patient who came to the clinic for 1-month history of lumbar pain associated with hematuria. Abdominopelvic tomography with contrast reported a neoformative lesion in the middle third of the left kidney, 7.6 x 6.2 cm, and calcifications a in the proximal ureter on the same side. Treatment consisted of left open radical nephrectomy with regional lymphadenectomy. Microscopic findings reported neoplastic cells arranged in an acinar and tubular pattern, round nucleus, broad clear cytoplasm, and prominent nucleolus at X100 magnification (a fine interlaced vascular pattern was observed among them). The histopathological diagnosis of renal cell carcinoma, a clear cell variety with histological grade ISUP G3, was established. A dense atypical lymphoid proliferation was identified in the perihilar region, characterized by medium to large cells that spread and affected the perirenal fat and the renal sinus, and whose immunohistochemical studies were positive for CD20 and BCL-6. Concomitant coexistence with a diffuse large B-cell lymphoma of the germinal center type has been reported. Both tumors had surgical margins and lymph nodes (0/11) free of malignant neoplasia. The patient received two cycles of R-CHOP. Later, he processed his transfer to a hospital closer to his place of residence; however, it was lost to follow-up by our institution. CONCLUSIONS: The coexistence of both neoplasms in the kidney is an exceptional event. It causes many challenges to be investigated, from the accurate pre-surgical diagnosis to the adequate treatment plan to the possible risk factors involved in its origin. [ABSTRACT FROM AUTHOR]
