An example of localized amyloid deposition in the breast of an elderly woman is reported. Fine needle aspiration biopsy yielded clumps of amorphous material, which stained violet with the May-Grünwald-Giemsa technique. The amyloid appeared to be of the AA type on histochemical analysis. The lesion was clinically associated, probably coincidentally, with a stage II carcinoma of the cervix. The nature and classification of amyloid is briefly reviewed, and the role of fine needle aspiration cytology in its diagnosis is discussed.
Three cases of nonpapillary carcinoma of the thyroid are reported in which intranuclear vacuoles or (pseudo)inclusions were observed in fine needle aspiration smears. Two of the cases had medullary carcinoma; one had a poorly differentiated follicular carcinoma. The cytologic, histologic and ultrastructural appearances of intranuclear vacuoles and of the so-called ground-glass nuclei of papillary carcinoma are described, and the diagnostic significance of these findings is discussed briefly. Intranuclear vacuoles are distinct and different from ground-glass nuclei.
