Clinical SummaryEdit

This 68-year-old white male had a local excision of a pigmented lesion (melanoma) on the skin of his back. Three years later he became aware of a "lump" in his left axilla. Examination confirmed the presence of a 2.3-cm nodular lesion. Subsequently, the patient underwent a surgical procedure for removal of axillary lymph nodes.

ImagesEdit

Nodular hyperplasia of the prostate--characterized by large discrete prostatic nodules--is a common disorder in men over 50 years of age. The nodules cause the prostate to be enlarged and to have an increased weight. The human prostate is surrounded by a restrictive capsule. These nodules cause increased pressure within the capsule which leads to constriction of the urethra as it passes through the prostate. Urethral constriction leads to retention of urine.
