We report a case of thymic well-differentiated neuroendocrine carcinoma (atypical carcinoid) in a 68-year-old woman. Intraoperative tumor touch smear results showed loose aggregates of epithelial cells with rich cytoplasm. These cells had variably-sized round to oval nuclei accompanying "salt and pepper" chromatin. Although no necrosis was found, a few mitotic figures were observed. We diagnosed the lesion cytologically as thymic well-differentiated neuroendocrine carcinoma (atypical carcinoid). Immunocytochemical results showed tumor cells to be positive for synaptophysin. This report highlights the need for carefully observing mitotic figures when diagnosing thymic carcinoid.
