A tumor of the vulva with sarcomatoid features was studied by immunocytochemistry to characterize the phenotype of the spindle-shaped and giant cells. Sarcomatoid-looking cells were positive for intermediate filament keratin polypeptides of stratified epithelium. These results favor histogenesis of the sarcomatoid-looking cells from a metaplastic alteration(More)
Solitary fibrous tumour (SFT) is a rare tumour principally found in adults in the pleural cavity. Extrapleural occurrences are rare. Two cases of SFT of the thyroid gland are described in this paper showing their distinctive microscopical architecture, namely "patternless growth pattern". It is characterized by a bland spindle-cell proliferation alternating(More)
AIMS AND BACKGROUND Sentinel lymph node dissection (SLND) has recently been evaluated as a new staging technique for early breast cancer. To minimize the extent of surgery, the feasibility of eradicating primary breast lesions and the relative sentinel lymph nodes (SLN) under regional anesthesia was evaluated in this study. METHODS AND STUDY DESIGN A(More)
The purpose of the present research has been to identify a cellular parameter to be used as an index of increased cell proliferation and, therefore, the likelihood of recurrence. A total of 114 patients with bilateral nasal polyposis underwent naso-ethmoid dissection under endoscopy. Of these, 36 were affected by allergic rhinopathy, 6 bronchial asthma, 9(More)
BACKGROUND Radioguided-surgery has been recently proposed in patients with clinically occult breast lesions. This study aimed to evaluate the feasibility of correctly locating and eradicating, by a single intralesional injection of a radiotracer, any breast lesion and, in the case of malignancy, to perform simultaneous sentinel lymph node (SLN) biopsy(More)
Experimental studies suggest that DNA content is increased in the smooth muscle cells of the arteries of hypertensive animals. It is unclear whether an increase in DNA content occurring in the smooth muscle cells of hypertensive rats represents a pressure-dependent effect. To evaluate the antihypertensive effect of long-term treatment with(More)
We describe a case of a patient with Creutzfeldt-Jakob disease (CJD) characterized by a rapid clinical course lasting one and a half months, by: presence of focal dystonic movements at onset, absence of mental deterioration in the period preceding the impairment of consciousness, ataxia, myoclonus and periodic EEG abnormalities. The autopsy confirmed(More)
Immunohistochemical quantitative evaluation of estrogen receptors (ER) detected in tissue sections from 30 breast tumors by monoclonal antibody was performed using a densitometric method. In particular, ER concentration was calculated by nuclear mean optical density (nMOD), while heterogeneity in ER content was calculated by the coefficient of variation(More)
BACKGROUND The objective of this study was to identify a reproducible clinical parameter for predicting relapses of nasal polyposis after surgery. METHODS Ninety-three patients who had undergone ethmoidectomy of bilateral nasal polyps were followed for 3 years. Nasal polyps were obtained from all patients, and cellular suspensions were analyzed(More)
