'Insufficient'/'Inadequate'/'Non-Diagnostic' Category of the WHO Reporting System for Lung Cytopathology, 2022: A Survey About Use in Practice.

Introduction: The new 'WHO Reporting System for Lung Cytopathology' (2022) includes an 'Insufficient'/'Inadequate'/'Non-diagnostic' category. Although they recommend that each laboratory should choose one term to report this diagnostic category, they do not recommend one term over the others. Our aim was to evaluate the use of these three terms in pulmonary FNACs among Spanish pathologists.

Incidental finding in urine cytology in a patient with chronic renal disease.

An incidental finding in urine smears from a patient with a presumptive diagnosis of an IgA mesangial nephropathy is presented. A possible example of the potential value of urine cytology in functional renal disorders. We report a case of an incidental finding in urine cytology from a patient with a presumptive diagnosis of an IgA mesangial glomerulonephritis, previously diagnosed as atypical urothelial cells.

Striated duct adenoma: The cytological description of a rare entity.

Introduction: Striated duct adenoma is a benign salivary gland tumour recently recognized by the World Health Organization. To date, no report has described the cytological features of this entity.

Materials And Methods: We report the case of a 60-year-old woman with a tumour in the right parotid gland with a diameter greater than 2.

Histopathologic Changes in Congenital Corneal Stromal Dystrophy: Report of 4 Cases in 2 Families.

Corneal dystrophies are hereditary diseases affecting the corneal tissue; they are bilateral, symmetrical and unrelated to environmental or systemic conditions. Congenital corneal stromal dystrophy is a very rare autosomal dominant dystrophy that is caused by a mutation in the DCN gene that encodes decorin (a proteoglycan of the extracellular matrix). We herein report 4 cases of congenital stromal corneal dystrophy in 2 families, highlighting the previously undescribed histopathologic features, the possible differential diagnosis of this entity and the key role played by decorin staining in its diagnosis.
