Sarcoidosis diagnosed on transbronchial fine needle aspiration smears: a case report with new information on asteroid bodies.

Sarcoidosis is a multisystem granulomatous disorder of unknown etiology. The fine needle aspiration cytologic features are noncaseating granulomas, lymphocytes and multinucleated giant cells (MGCs) with or without asteroid bodies. A 41-year-old man, an ex-smoker, presented to the Pulmonary Division of Mubarak Al-Kabeer Hospital, Safat, Kuwait, with chief complaints of dyspnea, wheezing and persistent cough of 6 weeks' duration.

Intranuclear cytoplasmic inclusions in fine-needle aspiration smears of papillary thyroid carcinoma: a study of its morphological forms, association with nuclear grooves, and mode of formation.

Intranuclear cytoplasmic inclusion (INCI) and nuclear grooves in fine-needle aspiration (FNA) smears of papillary thyroid carcinoma (PTC) represent cytoplasmic invaginations into the nucleus. Although formation of INCIs is linked to nuclear grooves, they seldom exist together. This study was undertaken to find out the various morphological forms of INCIs, their relation to nuclear grooves, and mode of formation.
