[A clinical case of secondary tumor of the penis from the rectum, with malignant priapism]

We report a clinical case of carcinoma of the rectum. A 45-year-old patient had undergone resection of the rectum and proctostomy 22 months ago. Carcinoma caused metastasis to the corpora cavernosa of the penis in this patient, and caused local recurrence of the carcinoma of the rectum, pulmonary metastasis and malignant priapism. A statistical analysis of 62 cases of secondary tumor of the penis in Japan was also made. The present clinical case was the 62nd case of secondary tumor of the penis in Japan, and the 4th case of secondary penile tumor from the rectum. The primary foci of the secondary tumor of the penis are mostly in the urinary bladder and the prostate, followed by the rectum, kidney, pelvis of the kidney and the ureter. Primary sites in the urogenital organs were found in 82.3% and in the neighboring organs in 85.2%. As the route of metastasis of the secondary tumor of the penis, arterial blood, retrovenous, retro-lymph and direct infiltrating metastasis may be possible. Secondary tumor of the penis is mostly found in aged persons, and the major symptoms may be penile nodule and mass, malignant priapism, penile pain and tenderness, and difficulty in urination and retention of urine. Regardless of the length to metastasis and difference in the treatment of the metastatic focus, the secondary tumor of the penis is poor in prognosis, and survival period may be up to 7 months. From the findings of post-mortem examination, secondary tumor of the penis should be regarded as a secondary sign due to recurrence of the primary tumor or presence of metastasis in other organs, and careless surgical operation should be avoided.

Unusual clinical presentation of metastatic prostatic carcinoma in elderly patients

Three elderly patients with unusual symptoms of metastatic prostatic carcinoma are presented. The first patient suffered from recurrent acute renal failure, the second presented with induration of penis, and in the third patient an acute onset of paraparesis was the presenting symptom of prostatic cancer. The incidence of such symptoms is reviewed and the importance of early diagnosis and therapy is discussed.

Penile metastases secondary to bladder cancer. Review of the literature

73 cases of penile metastatic tumors secondary to bladder cancer have been collected from the literature. The cases are reviewed in regard to incidence, geographical distribution, age, interval between diagnosis of bladder cancer and appearance of penile metastases, symptoms, physical examination, endoscopy, diagnosis, differential diagnosis, routes of metastases, pathology, treatment, and prognosis. The spread of the tumor in and along prostatic nerves is documented.

Bronchogenic carcinoma metastasizing to the heart and penis. A case report

Metastasis to the heart and penis from a primary bronchial carcinoma is rare in almost all histological groups of cancer. Bronchial carcinoma is known to give rise to widespread haematogenous metastases, but there are certain sites where these metastases are more likely to occur--bones, brain, liver and adrenal glands. A case is reported in which undifferentiated squamous carcinoma of the bronchus spread to two extremely uncommon sites, the heart and the penis.

Secondary tumors of penis

The penis, despite its rich vascular supply, is a very uncommon site of metastatic tumor. When present, the prognosis is extremely poor. Four cases of secondary tumors of the penis are presented and the literature reviewed.

Burkitt lymphoma metastatic to penis

The first known case of metastatic Burkitt lymphoma to the penis is presented. The penis is a rare site of metastatic neoplasm in spite of its rich blood supply. Less than 200 cases have been reported in the last one hundred years. Local control was achieved with radiation therapy.

[Metastatic tumors of the penis]

The authors present four cases of metastasic penis tumours, two of which followed a prostate carcinoma, one vesical carcinoma and the other a carcinoma of the excretory duct. They make a review of world literature on the subject and study the possible ways of dissemination as well as the clinical picture and differential diagnosis with other pathological processes of the male genital organ and they stress in particular the bad prognosis as the metastases appear at a very advanced stage of the primitive illness.

Metastatic carcinoma of the penis

Metastatic carcinoma of the penis is distinctly uncommon and in 80 percent of cases is associated with primary malignancy of the pelvic organs with widespread metastases. Pain and priapism are the most common symptoms at the time of the diagnosis. Both cases presented in this paper responded well to local irradiation, subjectively as well as objectively.

Pagetoid lesions associated with carcinoma of the bladder

Three cases of pagetoid infiltrations by a transitional cell carcinoma are reported. The theories of histogenesis of extramammary Paget's disease are reviewed and discussed. Evidence from these cases suggests that the lesion develops because of the intraepithelial migration of cells.

Metastases to the penis from carcinoma of the prostate. A case report

In a 68-year-old man metastasis to the penis was diagnosed about two years after transurethral resection of the prostate because of adenocarcinoma. Diethylstilboestrol has been given postoperatively. Initially the metastasis was interpreted as primary cancer of the penis, as biopsy findings indicated a spinocellular carcinoma. Subsequent biopsies, however, showed the same histologic pattern as in the original cancer of the prostate. Up to 1976 about 170 cases of metastasis to the penis were reported in the literature. The prognosis as a rule is very poor. In the present case estramustine phosphate (Estracyt) seemed to improve the patients's general health, but did not affect the penile metastasis. The patient died 18 months after the metastasis had been demonstrated.
