Necrotizing sarcoid granulomatosis (NSG), now referred to as "sarcoidosis with NSG pattern," is an uncommon variant of sarcoidosis. NSG is characterized by a trio of features: sarcoid granulomas, vasculitis, and extensive areas of necrosis. Symptoms can include cough, fever, chest pain, and dyspnea, typically presenting as either solitary or multiple lung nodules or masses.

Background/aim: Dendritic cells (DCs) are difficult to evaluate in lung regional lymph nodes because of region-specific structures, such as abundant trabeculae connecting the medullary and subcapsular sinuses, the latter of which contains few anthracotic macrophages. Therefore, DC-specific intercellular adhesion molecule-3-grabbing non-integrin (DCsign)-positive DCs and CD68-positive macrophages are unlikely to show a typical distribution. The present study therefore explored quantitative factors connecting the nodal DC morphology to the patient outcome.

Background: Transbronchial needle aspiration (TBNA) of peripheral lung nodules can be difficult with conventional devices due to their limited flexibility. A promising new technology for accessing these lesions is the PeriView FLEX TBNA device, which has a flexible spiral-grooved needle. The present study reports the unique cytologic features, diagnostic value, and potential pitfalls of PeriView FLEX TBNA specimens.
