Sarcoid Vasculitis in the Skin: A Clinicopathologic Study of 8 Cases With Various Skin Lesions but the Common Unique Cannonball-like Vessel Destruction by Sarcoid Granulomas.

Department of Dermatology, Fukushima Medical University, Fukushima.
While the skin is a common target organ for sarcoidosis, cutaneous granulomatous vasculitis is rare among patients with sarcoidosis. Due to the lack of detailed studies on cutaneous sarcoid vasculitis, both dermatologists and pathologists remain unfamiliar with this rare but important vasculitic disorder. We clinicopathologically evaluated eight cases with biopsy-proven cutaneous vasculitis and cutaneous sarcoidosis and analyzed morphologic changes in the process of vasculitis for both small vessels and muscular vessels in detail.

Article Synopsis
- Lung masses can be benign or malignant, and Multi-detector CT (MDCT) plays a critical role in helping to differentiate between these types, although histopathological confirmation through biopsy is often necessary for a definitive diagnosis.
- The study aimed to evaluate the diagnostic accuracy of MDCT in distinguishing benign from malignant lung masses and to correlate imaging findings with results from CT-guided biopsies.
- Conducted over 17 months with 52 patients, the study used descriptive statistics to analyze the effectiveness of CT-guided biopsies and the diagnostic performance of MDCT in identifying thoracic lesions.
Comparative Efficacy of Magnetic Resonance Cholangiopancreatography vs. Percutaneous Transhepatic Cholangiography With Percutaneous Transhepatic Biliary Drainage Stenting in Evaluating Obstructive Jaundice: A Prospective Study in South India.

Introduction Obstructive jaundice due to proximal biliary obstruction presents significant diagnostic and therapeutic challenges. Accurate and timely diagnosis is essential for effective management. Objective/aim This study aimed to evaluate and compare the diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) and percutaneous transhepatic cholangiography (PTC) along with percutaneous transhepatic biliary drainage (PTBD) stenting in obstructive jaundice, while also incorporating the comparison of ultrasonography (USG) and computed tomography (CT) findings.

Intrahepatic cholangiocarcinoma (iCCA) is a prevalent liver tumor that presents a diagnostic challenge due to its nonspecific symptoms, necessitating reliance on imaging techniques for accurate diagnosis. The similarity of imaging features with other liver diseases, such as hepatocellular carcinoma (HCC) and hepatic alveolar echinococcosis, often leads to confusion and misdiagnosis. In contrast, the distinct characteristics of hepatic cystic echinococcosis (HCE) result in fewer reported misdiagnoses.
