Jejunal Amyloidoma - a rare cause of gastrointestinal bleeding

We report a case of localized amyloid tumor of the jejunum which presented with abdominal pain and gastrointestinal bleeding. We reviewed the pathophysiologic process that precipitates bleeding in this rare tumor. We also examined the documented radiologic and endoscopic features of amyloidosis of the small bowel in the light of our reported case. All with a view to add to the growing evidence on this rare tumor which will facilitate accurate diagnosis and management

Feasibility of purely laparoscopic resection of locally advanced rectal cancer in obese patients

Abstract Background Totally laparoscopic (without hand-assist) resection for rectal cancer continues to evolve, and both obesity and locally advanced disease are perceived to add to the complexity of these procedures. There is a paucity of data on the impact of obesity on perioperative and oncologic outcomes for totally-laparoscopic rectal cancer resection (TLRR) for locally advanced disease. Methods In order to identify potential limitations of TLRR, a single-institution database was queried and identified 26 patients that underwent TLRR for locally advanced rectal cancers (T3/T4) over a three-year period. Patients were classified as normal-weight (NW, body mass index (BMI)=18.5 to 24.9kg/m2), overweight (OW, BMI=25 to 29.9kg/m2) and obese (OB, BMI >/= 30kg/m2). Perioperative outcomes, lymph node harvest and margin status were assessed. Results Seven patients were classified as NW (26.9%), 12 as OW (46.2%) and 7 as OB (26.9%). Age, tumor stage, gender and American Society of Anesthesiologists (ASA) scores were similar. OB had more co-morbidities (median 3.0, range 0.0 to 5.0 vs. 2.0, range 0.0 to 3.0 for NW and 1.0, range 0.0 to 3.0 for OW). Five patients had tumors Conclusion The perceived limitation that obesity would have on TLRR was not demonstrated by the analyzed data. Although our findings are limited by the modest sized cohort, the results suggest that it is reasonable to offer TLRR to obese patients with rectal cancer.</p

Malignant adnexal tumors of the skin: a single institution experience

Abstract Background Malignant adnexal tumors of the skin (MATS) are rare. We aimed to measure the survival of patients with MATS and identify predictors of improved survival. Methods A retrospective review of MATS treated at our institution from 1990 to 2012. Results There were 50 patients within the time period. Median age was 59.5 years (range 22–95); primary site was the head and neck (52%); most common histologic subtypes were skin appendage carcinoma (20%) and eccrine adenocarcinoma (20%); and the vast majority were T1 (44%). Most patients (98%) underwent surgical treatment. Chemotherapy and radiation were administered to 8 and 14% of patients, respectively. Recurrence rate was 12%. Median OS was 158 months (95% CI, 52–255). OS and recurrence-free survival at 5 years were 62.4 and 47.4% and at 10 years 56.7 and 41.5%, respectively. Five-year and 10-year disease-specific survival (DSS) was 62.9%. Age > 60 years was an unfavorable predictor of OS (HR 12.9, P < .0008) and recurrence-free survival (RFS) (HR 12.53, P < .0003). Nodal metastasis was a negative predictor of RFS (HR 2.37, P < 0.04) and DSS (HR 7.2, P < 0.03) while treatment with chemotherapy was predictive of poor DSS (HR 14.21, P < 0.03). Conclusions Younger patients had better OS and RFS. Absence of nodal metastasis translated to better RFS and DSS. Lymph node basin staging is worth considering in the workup and treatment
