- A case of pancreatic schwannoma was reported, which was initially misidentified as pancreatic carcinoma due to its similar characteristics before surgery.

- This case highlights the importance of considering schwannoma in the differential diagnosis of pancreatic tumors, despite its rarity.
Background: Percutaneous transhepatic gallbladder drainage (PTGBD) is recommended for acute cholecystitis patients at high risk for surgical treatment. However, there is no evidence about the best timing of surgery after PTGBD. Here, we retrospectively investigated the influence of the interval between PTGBD and surgery on perioperative outcomes and examined the optimal timing of surgery after PTGBD.

Background: Cutaneous manifestations are the most frequent, and often the initial feature of extra-articular involvement in patients with rheumatoid vasculitis.
Objectives: The purpose of the study was to evaluate the clinical and histological spectrum of cutaneous vasculitis and the associated systemic involvement in patients with rheumatoid vasculitis.
Methods: Among 525 patients with rheumatoid arthritis, 20 tissue specimens with histologically proven cutaneous necrotizing vasculitis from 11 patients were investigated by studying the types and levels of affected vessels and related clinical features.
