Cystosarcoma phylloides.An ultrastructural study

Multifocal histogenesis of a cystosarcoma phyllodes.

An unusual multifocal cystosarcoma phyllodes is reported. It presented as a small, circumscribed tumour mass, which was associated with two diffuse neoplastic lesions which arose sequentially in two geographically separate parts of the mammary disc. Microscopically the tumour appeared to have been enlarging by the formation of isolated satellite tumour nodules within the adjacent normal breast ...

Ultrastructural Study in Canine Prostatic Hyperplasia

Chlormadinone acetate (CMA) and cyproterone acetate have been used in medicaltreatment of human benign prostatic hyperplasia (BPH) or prostatic carcinoma [2,3,8,9]. The atrophic effects of CMA on the prostate of rats and dogs have been previously reported from our laboratory[5,6]. Using spontaneous BPH dogs we found that immunostaining of androgen receptor (AR) in both epithelial and stromal fi...

Ultrastructural study of pleural fluid in mesothelioma.

Thirty-two pleural fluids were examined by electron microscopy from patients with malignant pleural tumours. Nine of these cases were patients judged to have malignant pleural mesotheliomas, and in all, 22 specimens were examined from this group and form the basis for this report. The criteria on which the diagnosis of a pleural mesothelioma was based included (a) the absence of any other sourc...

Biochemical and ultrastructural study of Blastocystis hominis.

This study was prompted by the paradox of strong presence of mitochondria in an anaerobic protozoan, recently reclassified from the yeasts. Stemming from publication in 1911 to 1912, Blastocystis hominis has been generally accepted as a harmless intestinal yeast of humans, with short standardized textbook (parasitology) descriptions, even to the present day. Reports since 1967 have changed the ...
