[A case of spontaneous peripelvic extravasation associated with ureteral stenosis caused by retroperitoneal lymph node metastasis of ascending colon cancer].

A case of spontaneous peripelvic extravasation associated with ureteral stenosis caused by retroperitoneal lymph node metastasis of the ascending colon cancer is reported. A 47-year-old woman complained of colic on right costa-vertebral angle. Excretory urograms showed right peripelvic extravasation and CT-scan showed urinoma formation around right kidney. Subsequent examination of right retrograde pyelo-ureterograms showed ureteral stenosis at sacro-iliac region. Operative findings revealed ureteral stenosis caused by retroperitoneal lymph node metastasis of ascending colon cancer, which was regarded as inoperable. There are a few reports of spontaneous peripelvic extravasation caused by a malignant tumor in Japanese literature. Twenty of them are reviewed.

[A case of malignant Sertoli cell tumor of the testis].

A 74-year-old man consulted our hospital about a painless swelling of the right scrotal contents. Laboratory findings showed no abnormalities. A right high orchiectomy was performed. The tumor measured 4.2 X 6.0 cm in size and was yellow-white in color. Histologically, the tumor was diagnosed as a malignant Sertoli cell tumor on the basis of findings of invasion and a high mitosis rate. Combined chemotherapy was performed after the operation and no recurrence was found. The Sertoli cell tumor of the testis is a rare neoplasm, and its malignant type is extremely rare. In Japan, 7 cases have been reported, and only 2 of them have been malignant. This case is the 3rd instance malignant Sertoli cell tumor in this country.

[Two cases of paratesticular rhabdomyosarcoma].

Two cases of paratesticular rhabdomyosarcoma are reported. A 15-year-old boy was admitted in July, 1983, with a 3-week history of gradually increasing painless scrotal swelling on the right side. With the suspicion of testicular cancer, right radical orchiectomy was performed and pathological examination revealed an embryonal rhabdomyosarcoma of the paratesticular region. Chemotherapy and retroperitoneal lymphadenectomy were performed, and the latter revealed lymph node metastasis at the bifurcation of the aorta. Radiotherapy was not done because of adherent ileus. About 8 months after the orchiectomy, he died of recurrence at pelvic cavity and brain metastasis. A 6-year-old boy presented in March, 1985, with a complaint of right scrotal swelling that was painless and gradually increasing for about a month. Transinguinal exploration revealed a paratesticular neoplastic lesion and right radical orchiectomy was performed. Pathological diagnosis was paratesticular embryonal rhabdomyosarcoma. No evidence of metastasis was found by chest X-ray, excretory urogram, abdominal CT-scan or lymphangiography. As post-operative treatment, only chemotherapy was performed, and 9 months after the orchiectomy, the patient was asymptomatic. Ninety four cases of paratesticular rhabdomyosarcoma found in the Japanese literature are reviewed and mainly the policy of treatment is discussed.

[Clinical study of testicular tumors (59 cases in Sakai Municipal Hospital)].

Fifty-nine cases of testicular cancers were admitted to our hospital between 1960 and 1984. Thirty cases were seminoma (patients aged 12-64 years) and 29 cases were non-seminoma (6 patients were 1-7 years old and 23 were 17-44 years old). One of each of the seminoma and non-seminoma cases was not included in our analysis due to death before sufficient treatment. Of the remaining 29 cases of seminoma, 24 were in stage I, 4 in stage II, and 1 was in stage III. Of the remaining 22 adult cases of non-seminoma, 15 were in stage I, 2 in stage II, and 5 in stage III. Most of the cases with seminoma were treated with radiation after orchiectomy. Two of the cases of advanced seminoma and all of the cases of non-seminoma without mature teratoma were treated with retroperitoneal lymphadenectomy and/or chemotherapy after orchiectomy. Of the seminoma cases, only one patient (stage II cancer) died. On the other hand, only one of the non-seminoma patients in stages II and III remained alive. Since 1979, 5 patients with stage III or bulky stage II disease have been treated with the PVB protocol and 4 were evaluable. Only one patient achieved complete remission (CR) but he suffered a relapse within a short period (4 months). Three patients were partial responders and two of them achieved CR following resection of residual disease and additional VAB-6 induction. Currently, none of the patients who were treated with the initial PVB protocol alone remain in CR.

[Transverse ectopia of the right testicle and tumor of the left testicle with immature uterus and fallopian tubes: report of a case].

A case of transverse ectopia of the right testicle and the left testicular tumor with the immature uterus and the fallopian tubes is reported. The patient, a 27-year-old married man, was admitted to our hospital with the suspicion of left testicular tumor and right undescended testicle. In his left scrotum, a double hen-egg-sized tumor was palpable and the right scrotum was empty. Exploration of the left inguinal canal disclosed double testicles with hernia uteri inguinalis. The right testicle showed transverse ectopia, and the histological finding of the left testicle was choriocarcinoma. In our review of the Japanese literature, we discovered 67 reported cases of transverse testicular ectopia. 33 (49.3%) out of 67 cases had a uterus and 9 cases (13.4%) had testicular tumor.

[A case of non-specific inflammatory granuloma of the bladder with marked eosinophilic infiltration].

A case of non-specific inflammatory granuloma of the bladder with marked eosinophilic infiltration is reported. A 54-year-old woman was admitted to our hospital on March 9, 1983, with the suspicion of bladder cancer. Her primary complaints were miction pain, frequency and gross hematuria. Cystoscopic examination revealed a hemi-sphere-shaped tumor at the dome of the bladder. Biopsy revealed no malignancy and marked eosinophilic and macrophagocytic infiltration of the submucosa. The patient was treated with antiallergic drugs and antibiotics with excellent relief of symptoms and objective remission of bladder findings on repeated cystoscopy and computed tomography.

Ocular manifestations of the 1976 rubella epidemic in Japan.

Of 79 cases of rubella during the 1976--1977 rubella epidemic in Japan, 56 (70.9%) had mild conjunctivitis. Six (7.6%) showed epithelial keratitis, but the epidemically estimated incidence of keratitis was about 2% (two cases with rubella keratitis per 75 cases of rubella). No evidence of disease of the anterior chamber or the fundus was observed. Characteristic features of keratitis in juvenile rubella were fine punctate epithelial opacities mainly disseminated in the central area of the cornea. The punctate lesions were about 0.1 mm in diameter on an average, but varied in number from a few to about 100. In many cases, keratitis developed about one week after skin rash and disappeared within one week with no sequelae.
