Parathyroid carcinoma with occult bone metastases diagnosed by fine needle aspiration cytology.
A case with persistent hypercalcemia following complete resection of a primary parathyroid carcinoma is presented. An occult bone metastasis was diagnosed by fine needle aspiration (FNA) cytology of a lytic bone lesion clinically presumed to be a "brown tumor" of hyperparathyroidism. The cytologic features of the metastatic lesion were similar to those of the resected primary lesion and of a previously identified metastasis. The potential usefulness of FNA cytology in this clinical setting is discussed.
