Fine‐needle aspiration of metastatic atrial myxoma

Atrial myxoma is the most common primary neoplasm of the heart, but “metastatic” or embolic phenomena are rare. The first reported case of “metastatic” atrial myxoma diagnosed by fine‐needle aspiration biopsy is presented. It occurred in a 54‐yr‐old woman with multiple metastatic lesions. The cytologic and histologic findings of the fine‐needle aspiration biopsy and subsequent surgical excision are presented as is a discussion of the incidence, origin, and clinical findings of atrial myxoma and the characteristics of its emboli.
