Primary malignant melanoma of the adrenal gland.

Primary malignant melanoma of the adrenal gland is an established entity. Fewer than 20 cases have been reported in the published literature. Because of the high frequency of adrenal gland metastases from malignant melanoma and pigmented pheochromocytoma, several rigid diagnostic criteria have been established for accepting an adrenal melanoma as primary.

[Feasibility and value of the isotope sentinel node mapping technique in prostate cancer].

Objective: Use of an isotope sentinel node mapping technique in prostate cancer to study its feasibility, lymphatic prostate drainage and its value in pelvic lymph node staging.

Material And Method: The sentinel node mapping technique was performed in 34 patients with clinically localized prostate cancer. A transrectal intraprostatic injection of Technetium 99m-labelled nanocolloidal particles was performed on the day before radical prostatectomy.

[Evaluation of non-enhanced spiral CT in the assessment of renal colic: prospective series of 81 patients].

Objective: For many years, intravenous urography has been the first-line investigation for renal colic. Since the middle of the 1990s, non-enhanced spiral CT has become a more efficient, less invasive and less expensive alternative to IVU. The aim of this study was to compare non-enhanced spiral CT and IVU in the assessment of renal colic and to evaluate the possibility of exclusive CT assessment in this disease.
