Assessing ROSE for adequacy of EBUS-TBNA compared with a direct-to-cell block approach as a response to the COVID-19 pandemic.

Introduction: Rapid on-site evaluation (ROSE) has been used during the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) procedure as standard practice. Because of the COVID-19 (coronavirus disease 2019) pandemic, our institute had had to discontinue ROSE and adopt a direct-to-cell block approach. In the present study, we aimed to determine whether this change has had significant effects on the cytopathology quality.

Sclerosing epithelioid fibrosarcoma: cytologic characterization with histologic, immunohistologic, molecular, and clinical correlation of 8 cases.

Introduction: Sclerosing epithelioid fibrosarcoma (SEF) is an uncommon malignant fibroblastic neoplasm. The diagnosis is typically made on core needle biopsy or resection specimens. Cytomorphologic characterization of SEF has been limited to rare case reports in the literature.
