Pancreatic neuroendocrine tumors (PanNETs) are typically solid neoplasms but in rare instances may present as cystic lesions. This unusual presentation can make clinical diagnosis challenging. In addition, the clinical and histopathologic characteristics of cystic PanNETs are poorly defined. We identified 53 cystic PanNETs in our single-institution experience of 491 surgically ...

Traumatic shoulder dislocation may be complicated by concomitant bony injury of the glenoid rim or the humeral head. In Hill-Sachs lesions, reconstruction techniques vary widely and range from open reduction to tendon transposition or humeral head derotation. These operations are extensive and have questionable outcomes. With the expertise from vertebral ...

Clinically equivocal abdominal wall lesions often pose diagnostic dilemmas for clinicians. It can be equally challenging to appreciate the nature of abdominal wall lesions found incidentally on abdominal ultrasound examinations. Ultrasound is a non-ionizing, cheap, and easily accessible investigation for such lesions. It is widely used and has the added ...

What's known on the subject? and What does the study add? Transrectal ultrasonography (TRUS)-guided biopsies can miss prostate cancer and misclassify risk in a diagnostic setting; the exact extent to which it does so in a repeat biopsy strategy in men with low-intermediate risk prostate cancer is unknown. A simulation ...

Paleopathological assessment of the late Middle Pleistocene archaic human cranium from Maba, South China, has documented a right frontal squamous exocranially concave and ridged lesion with endocranial protrusion. Differential diagnosis indicates that it resulted from localized blunt force trauma, due to an accident or, more probably, interhuman aggression. As such ...

Squamous odontogenic tumor-like epithelial islands occurring in the walls of odontogenic cysts are histologically identical to the squamous odontogenic tumor (SOT). Microscopically, the squamous odontogenic tumor-like proliferations (SOTLPs) share certain histologic features with SOT, acanthomatous and desmoplastic ameloblastoma, and well-dif-ferentiated squamous cell carcinoma. Little is known about the rarely reported ...
