[Congenital perineal lipoma with accessory scrotum: a case report].

A tumor mass covered with scrotum-like skin on its tip was found on the perineal region of 3-year-old boy since his birth. The mass was diagnosed as congenital lipoma, which was resected, because of its gradual enlargement. Histopathological findings of the tumor indicated perineal lipoma, and the scrotum-like portion was diagnosed as an accessory scrotum. In the Japanese literature, 7 congenital perineal lipomas (6 males, 1 female) have been reported and all male cases except 1 case (no description about scrotum) were accompanied with an accessory scrotum. We conclude that there may be a close relationship between congenital perineal lipoma and accessory scrotum.

Delayed development of the scrotum in exstrophy.

Early attempts at orchiopexy should be avoided in children with exstrophy, since the testes will often descend spontaneously by puberty. In many cases the scrotum will grow much larger and will become pendulous by puberty. In a patient with a rudimentary scrotum orchiopexy will only result in fixing the testes in an abnormally high position owing to the lack of a sac into which to place them. If the scrotum develops later the testicles will probably be unable to descend further. Scrotal skin should not be used for urethroplasty operations in children with exstrophy and special techniques should be applied if it is necessary to repair hernias in these patients. In the child with partially descended testes but with only a small patch of wrinkled scrotum efforts may be undertaken to increase scrotal size by topical hormone treatment (or by injections) before the onset of puberty to help fertility and emotional development.

A technique for the correction of bifid scrotum in patients with hypospadias.

A technique to correct a bifid scrotum in patients with severe hypospadias is described. The operation is used as a second stage procedure to 1) repair the bifid scrotum, 2) add length to the penis and 3) correct the tendency for the erect penis to point into the scrotum, eventually interfering with intromission. The procedure, which advances the penis superiorly, detaches the urethra from the prominent median raphe to correct the bifid scrotum, It has been used successfully in 3 patients.

Accessory scrotum with lipoma in an infant.

We report on a 2-year-old male infant with accessory scrotum with lipoma presenting a perineal mass. Preoperatively no abnormality in the urinary tract and the anorectum was demonstrated. The tumour was resected and perineoplasty was performed. The resected specimen histologically revealed lipoma with tissue suggestive of scrotum. The patient recovered well and was discharged with no clinical complaints. This rare congenital anomaly is described in this paper. The slight continuity between the left scrotum and an accessory scrotal tissue in this case may suggest that this rare anomaly was derived from some abnormality in the migration of precursor tissue of scrotum.

Pedunculated leiomyoma of scrotum.

Leiomyoma may originate at any anatomic location of smooth muscle in the genitourinary system. The kidney capsule is the most common site for the genitourinary leiomyomas. Leiomyoma origination from the scrotum is rare. The previous reported cases presented as small, firm, nontender, slowly enlarging freely movable masses within the scrotum. We report a case of leiomyoma of the tunica dartos, a benign lesion arising from the wall of the left scrotum. It presented as a pedunculated lesion with a surface ulceration, which need to be differentiated from squamous carcinoma of the scrotum. It was treated with a simple surgical excision.

[Giant epidermoid cyst of the scrotum: a case report].

A 74-year-old male with the chief complaint of painless enlargement of a mass in the scrotum was diagnosed as having a giant epidermoid cyst on July 8, 1991. He had no past history of injury or pain of the scrotum. Magnetic resonance imaging (MRI) of the scrotum demonstrated a well-circumscribed homogeneous mass, and was distinguished from both normal testes. Under the diagnosis of intrascrotal epidermoid cyst, the mass was resected surgically. The mass measured 23 x 15 x 15 cm, and it contained liquids. The pathological diagnosis was epidermoid cyst of the scrotum.

[The content of DNA, RNA and protein and the fresh weight:DNA, protein:DNA and RNA:DNA ratios in tissue of male calves, bulls, short-scrotum bulls and oxen during the growth period].

In male calves, in bulls, in short scrotum bulls and in oxen of different age the content of DNA, RNA and protein in various tissues (cerebrum, cerebellum, spinal cord, ventricles, lung, liver, cortex of the kidney, spleen, testicles, M. semimembranosus) was analysed. The fresh weight: DNA-, the protein: DNA- and the RNA: DNA-ratios were calculated. In the age of 78 weeks the short scrotum bulls had a body weight of 577 +/- 44, the bulls of 550 +/- 21 and the oxen of 462 +/- 41 kg. The testicles of the short scrotum bulls were smaller than that of the bulls. The differences in the content of DNA, RNA and protein per g tissue between male calves, bulls, short scrotum bulls and oxen of the same age were in part significant. The total content of DNA, of RNA and of protein for the 78 weeks old as well as the number of nuclei of the lung, the liver, the spleen and the testicles for the 6 and 78 weeks old animals were calculated. The biochemical parameters can be used for the characterization of the inhibition of growth of the different organs of calves and cattle by malnutrition and diseases.

[The content of beta-carotene, vitamin A and ascorbic acid in different tissues of bulls, short-scrotum bulls and oxen of different body weights].

Analyses of the liver of bulls of different age show, that the concentration of beta-carotene in the age of 6 to that of 25 weeks increased only from 0.43 +/- 0.16 to 1.66 +/- 0.27 and that of vitamin A from 11.49 +/- 5.87 to 13.90 +/- 5.21 micrograms/g fresh weight. The concentration of beta-carotene and of vitamin A in the testis of bulls and of short scrotum bulls up to an age of 15 weeks was similar; thereafter the concentration in the short scrotum bulls was higher. At an age of 72 weeks the concentration of vitamin A in the liver of bulls (219.17 +/- 51.86) was higher (p less than 0.01) than in that of the short scrotum bulls (144.11 +/- 27.79) and that of the oxen (135.51 +/- 41.26 micrograms/g fresh weight). Analyses of the concentration of ascorbic acid in 8 different tissues of bulls and short scrotum bulls at 6 various periods show, that the highest values mostly were found in December.

On the use of the scrotum for feeding larval ixodid ticks on hosts.

The efficacy of feeding larval stages of Amblyomma variegatum, Hyalomma rufipes and Boophilus decoloratus on the ears and scrotum of sheep is compared. The effect of age of larvae on the number that engorged on the animal was also investigated. A significantly greater number of larvae fed on scrotum than on ears. The greatest number of larvae engorged when they were fed on the scrotum or ear within 1-4 days of hatching. The older the larvae, the less the number that fed. The economic advantages of adopting the scrotal method for rearing larval tick stages as well as the implication under natural conditions of younger larvae feeding in large numbers are discussed.

Incomplete prepenile scrotum: report of two cases and review of literature.

An incomplete prepenile scrotum is an unusual anomaly. Two cases of incomplete prepenile scrotum are presented here, both of which are associated with a small phallus, hypospadias and a bifid scrotum. No sex chromosome disorder or hereditary factors contribute to such a disorder. Early surgical correction is recommended.

[One-stage operation for treatment of transposition of penis and scrotum complicated by hypospadia].

Transposition of penis and scrotum is often complicated by hypospadia and used to be corrected by staged operation. Since 1984 a new procedure has been developed in which the transposition of penis and scrotum and clubbed penis were corrected, and urethroplasty was performed at same time. Six children received this operation uneventfully. Postoperative follow-up revealed that normal penis position, erection and urination were achieved in these patients. This operation is applicable to patients with transposition of penis and scrotum complicated by various hypospadia. The operative method and key to ensure success are described in this article.

Squamous-cell carcinoma of the scrotum.

Squamous-cell carcinoma of the scrotum has a poor prognosis unless locally confined. Patients with stage A1 disease have approximately a 75% or better chance for long-term survival. Occupation-related and -induced scrotal carcinomas are less frequent now because of better hygiene, protective clothing, and awareness of the carcinogenicity of industrial oils. A rise in the incidence of the disease might result from the HPV epidemic. The basic treatment of squamous-cell carcinomas of the scrotum still depends on wide local excision of the primary lesion. Patients should be treated with a broad-spectrum antibiotic for 4 to 6 weeks prior to sentinel node biopsy or ilioinguinal lymphadenectomy. Sentinel node biopsy should be performed to rule out micrometastasis and to establish the need for a formal ilioinguinal lymphadenectomy. Radiation therapy has little therapeutic benefit in the management of squamous-cell carcinoma of the scrotum. Bleomycin might be useful as adjuvant therapy for widespread ilioinguinal disease before attempted resection, although this has yet to be proved.

[Duplex echography in acute scrotum. Diagnostic possibilities].

Acute scrotum is a frequent reason for consultation at the urological emergency service. The most common causes, apart from trauma, are acute orchiepididymitis, torsion of the hydatids of Morgagni and torsion of the spermatic cord. Apart from a detailed examination of patient history and a careful physical examination, few diagnostic techniques can be utilized. To date, only the Doppler ultrasound has proved useful in corroborating the suspicion of vascular involvement, although this technique is very limited. With the availability of the duplex ultrasound, the possibility of making the differential diagnosis in the acute scrotum is enhanced. This technique permits morphological and functional assessment and avoids unnecessary exploration surgery within the scrotum.

Total reconstruction of a two-compartment scrotum by tissue expansion.

A case report is presented showing the reconstruction of a two-compartment scrotum out of hair-bearing perineal skin following a severe degloving injury of the scrotum and testicles. We feel that this is an appropriate procedure to be used in patients who have lost the testicles and scrotum traumatically, either one or both testicles, or in the situation where both testicles have been spared. Aesthetically, the result in this patient is superior to skin grafting and should be readily reproducible.

[A recurrent gastric carcinoma found by metastasis to the scrotum].

Reported is a case of 67-year-old man with a recurrent gastric carcinoma that was associated with a possible lymphatic metastasis to the scrotum. Seven years earlier (October, 1980), since an adenocarcinoma of the stomach was present, a subtotal gastrectomy was performed. At that time, a IIc-like advanced tumor with a ul-III, measuring 32 x 28 mm in size, was noted on the anterior wall of the corpus near the greater curvature of the stomach, on macroscopical examination of the resected specimen. Microscopic findings showed a poorly differentiated adenocarcinoma with an involvement of the serosa but without a lymph node metastasis (H0, P0, n0, se, stage III). In July 1987, a tumor in the right scrotum was found and the patient underwent surgery. The resected specimen revealed a histologically cancerous involvement of the testis, the epididymis, the tunica vaginalis testis, and the spermatic cord. The cancerous cells showed the same poorly differentiated adenocarcinoma which had been observed in the primary locus of the stomach. Judging from these findings, this case was diagnosed as a recurrent gastric carcinoma with a lymphatic metastasis to the scrotum.

Leiomyosarcoma of the scrotum: a case report with electron microscopy.

A case of leiomyosarcoma of the scrotum is presented. The tumor measured 3 X 2.5 X 2 cm and had been present as a slowly enlarging mass in the right scrotum for three months prior to excision. Light microscopy demonstrated the typical interlacing fasicles of neoplastic cells with eccentric cigar-shaped nuclei and electron microscopy confirmed the neoplastic cells to be of smooth muscle origin. A review of the world's literature revealed this to be the fifth reported case of leimyosarcoma confined to the scrotal wall.

Thermoregulation of the scrotum and testis: studies in animals and significance for man.

This article reviews the extensive information available from experiments on animals concerning the thermal monitoring provided by the scrotum. Cutaneous temperature receptors initiate responses which follow unique pathways and undergo "switching" processing within the central nervous system. These pathways evoke reflex responses which are subject to control from receptors in other regions of the body, including the skin and temperature sensitive neurones in the brain and spinal cord. The local thermoregulatory responses of the scrotum, e.g., sweating and vasomotor changes, clearly have a role to play in the protection of the testis against temperature elevation in both man and animals. It is as yet more difficult to propose how general reflex responses may be of benefit in the protection of spermatogenesis against heat damage. This meeting should provide the stimulus for further work. The need is urgent since it may also provide a means to apply this knowledge to a better understanding of male infertility and possibly to speed the development of male methods of fertility regulation.
