Papillary breast lesions diagnosed on cytology. Profile of 65 cases.

Objective: To analyze the cytologic features of nipple discharge and fine needle aspiration (FNA) cytologic smears from breast lesions reported as showing papillary features and to correlate them with histopathologic features.

Study Design: The study group consisted of FNA smears and/or nipple discharge smears from 65 breast lesions diagnosed on cytology as duct papilloma, papillary lesion, fibrocystic condition, fibroadenoma, papillary neoplasm or papillary carcinoma. Cytomorphologic features assessed included cellularity, cell pattern (clusters, papillary, 3-dimensionality, etc.

Mucinous carcinoma (colloid carcinoma) of the lung diagnosed by fine needle aspiration cytology: a case report.

Mucinous carcinoma of the lung, also known as colloid carcinoma, is an uncommon tumour that is rarely encountered in fine needle aspiration (FNA) cytological practice. A 64-year-old Chinese male presenting with blood stained sputum and hoarseness of voice was discovered to have a 3 cm sized mass in the left lung. Neither bronchial washings nor transthoracic FNA yielded positive results at this stage.
