The lesion appeared as painless slowly growing mass in the right side of the lower lip. Histologically, infil-trative tumor nests with duct-like or pseudocyst structure into the mucosa and/or dermis were ob-served. The basaloid neoplastic cells had granular but occasionally vacuolated cytoplasm with salient reaction of diastase-digestible periodic acid-Schiff, thus indicating that they were glycogen-rich in nature. The tumor cells were positive for CEA, cytokeratin, and S-100 protein, and negative for SMA, alpha-1 antitrypsin, and amylase by immunohistochemistry. The origin of the tumor with infiltrative nests was indistinguishable from salivary gland and skin ap-pendage malignancy. A differential diagnosis of this peculiar neoplasm was discussed.展开更多

The purpose was to evaluate the value of CDFI in the diagnosis of DVI. The results demonstrated that the parameters between the two groups had a very significant difference (P<0. 001), indicating that the CDFI is non-invasive, cost-effective and safe and it might serve as a practical tool in the diagnosis of lower extremity deep va1vular incompetence.展开更多

With its clinical presentation, delayed diagnosis rarely happens. We report the case of a 12-year-old girl diagnosed seven days post-trauma with grade IV renal trauma complicated with infected urinoma and bilateral lower polar vessels. She was non-operatively managed with ultrasound-guided percutaneous drainage of the urinoma, which resolved, and had unremarkable six months follow-up. We discuss the role of preexistent hydronephrosis in low-velocity impact, pitfalls of diagnosis in resource-constrained settings, and management of high-grade trauma.展开更多
