Malignant priapism is a term originally coined by Peacock7 in 1938 to describe a condition of painful induration and erection of the penis due to infiltration by secondary neoplasm. In the case which he presented the patient developed penile metastases one and one-half years following treatment of a bladder carcinoma by transurethral fulguration. The penile lesion was found to be carcinoma metastatic from the bladder; and, when the patient died shortly thereafter, diffuse metastases were found.
This subject was reviewed in 1956 by Paquin and Roland,6 who summarized reports of 55 such cases from the literature and added 9 cases, making a total of 64 case records. Study of these patients indicated that the origin of the neoplasm which metastasized to the penis was the bladder in one-third of the cases. Neoplasms of the rectum and prostate accounted for 39% of the cases reported. The methods of spread
