Successful Treatment of Malignant Priapism by Radiotherapy: Report of a Case, Review of the Literature, and Treatment Recommendations.

Malignant priapism is a condition of painful induration and erection of the penis secondary to metastatic infiltration by a neoplasm. This condition is associated with a poor prognosis. We report on a case of an 87-year-old man who presented with a painful, partially erected penis subsequent to a diagnosis of metastatic Gleason 4+5 prostate cancer.

Biphasic papillary renal cell carcinoma is a rare morphological variant with frequent multifocality: a study of 28 cases.

Aims: To further characterise biphasic squamoid renal cell carcinoma (RCC), a recently proposed variant of papillary RCC.

Methods And Results: We identified 28 tumours from multiple institutions. They typically showed two cell populations-larger cells with eosinophilic cytoplasm and higher-grade nuclei, surrounded by smaller, amphophilic cells with scanty cytoplasm.

The distribution of immune cells and macrophages in the endometrium of women with recurrent reproductive failure I: Techniques.

Recurrent miscarriage affects approximately 1% of the population and in half of these cases no cause is found. Abnormally functioning immunocompetent cells, including natural killer (NK) cells, in the endometrium, are thought to be responsible for many such cases and treatment trials including oral prednisolone and intravenous immunoglobulins are now underway. Despite these encouraging developments, there is neither adequate standardization of counting uterine NK cells nor consensus as to what constitutes an abnormal level.
