Abstract |
Aspirated material from two cases of histologically and ultrastructurally confirmed adenocarcinoid tumor of the lung was evaluated. In one case, columnar and cuboidal cells with ill-defined cytoplasm and round or oval nuclei were seen in large sheets and syncytiumlike clusters with focal glandular arrangement. In the other case, spindle-shaped and columnar cells with ovoid nuclei and ill-defined cytoplasm were seen singly and in loose clusters. Fragments of tumor epithelium with nuclei arranged in pseudo-stratified pattern were noted. Staining of tumor cells by the Grimelius technique demonstrated numerous intracytoplasmic brown-black granules. The cytologic differential diagnosis between adenocarcinoid tumor and other primary and metastatic adenocarcinomas of the lung is briefly discussed.
