RESUMO
This paper describes our recent experience with one case of collagenous spherulosis of the breast which was diagnosed accurately by fine-needle aspiration (FNA) cytology. Histochemical and immunohistochemical studies were performed on the biopsy material. This curious lesion was found in association with benign proliferative breast processes but it can be found in association with both benign and malignant lesions in other organs and breast malignancies. The differential diagnosis of collagenous spherulosis is discussed.
RESUMO
The technique of impression cytology was used for cytologic examination of conjunctival samples from 128 patients with a variety of external eye diseases. The method of sample collection and the staining procedure are described. Microscopic examination showed 62 cases with allergic conjunctivitis, 23 with bacterial or viral infection, 26 cases with changes typical of dry eye and 17 cases with non-specific chronic inflammation. The cytologic features and numerous applications of impression cytology are discussed.
