Cytohistological findings and diagnostic challenges in rare pediatric pulmonary mesenchymal malignancies: A report of two cases.

Pulmonary mesenchymal tumors are uncommon neoplasms and the data available on their clinical, cytohistomorphological, immunohistochemical, and molecular findings are limited, leading to difficulty in timely diagnosis and management. Case 1: A 12-year-old boy presented with a right endobronchial mass. Imprint smears from endobronchial biopsy revealed moderately pleomorphic spindle cell tumor arranged in fascicles and perivascular pattern with attached myxoid material showing occasional mitotic activity suggesting a cytological diagnosis of sarcoma.
