A 31-year old woman was admitted to our clinic complaining of high blood pressure, dizziness, constipation, mental irritability and weight loss. The physical examination revealed goiter in her neck. The plasma levels of norepinephrine and epinephrine were 3.45 and 0.76 ng/ml, respectively. Urinary excretion of norepinephrine was 1 mg and epinephrine was 32.2 micrograms/24-hours. The examination by radiography and radioactive isotope revealed a tumor in the left adrenal region and another in the left lower lobe of the thyroid. After the operations, pheochromocytoma and papillary adenocarcinoma of the thyroid gland were recognized pathologically. However, 17 months later, the recurrence of pheochromocytoma in the contralateral adrenal region was discovered and removed. Although the co-existence of bilateral pheochromocytoma and papillary adenocarcinoma of the thyroid gland is not one of multiple endocrine neoplasia, to the best of our knowledge, only 7 such cases have been reported in the published literature.

A case of a endodermal sinus tumor of the ovary in a patient with 45,XO/46,X,dic(Y) mosaicism is reported because of the rarity of the karyotype and condition. A 15-year-old girl was admitted to Yamagata University Hospital because of constipation for several days. Physical examination showed webbing of the neck, cubitus valgus and short stature. Her abdomen was bulging. Chromosomal analysis showed 45,XO/46,X,dic(Yq) mosaicism in karyotype. alpha-Fetoprotein and CA-125 in the serum were high. A left ovarian tumor was found by laparotomy; however, the right ovary was a streak gonad and the uterus was hypoplastic. An endodermal sinus tumor was diagnosed by a pathologist. After operation, cisplatin-vinblastin-bleomycin chemotherapy was instituted and the tumor marker went down. This patient is still healthy and under observation at the outpatient clinic.

Presented is the case of a patient, a 56-year-old female, who had complained of bloody stool and constipation. A barium enema and endoscopic examination revealed a tumor (Type 2) with a crater surrounded by a thick embankment, extending from the anterior wall to the left wall of the lower rectum. Biopsy specimens of the tumor disclosed a well-differentiated adenocarcinoma. A FT-207 suppository (1500 mg/day) was administered preoperatively for 50 days (total dose 75 g). On February 16, 1987, the patient underwent an abdominoperineal excision. The resected specimen took on the appearance of a chronic ulcer with an irregular depression, measuring 2.0 x 3.0 cm in size, in the lower rectum. The histology of the lesion also indicated a chronic ulcer, the base of which consisted of fibrosis covered with regenerative mucosa. No cancer cells or nests were demonstrated even serial tissue sections. As far as the rectal carcinoma is concerned, there has been no reported case of its disappearance by preoperative chemotherapy. The above results suggest that preoperative adjuvant chemotherapy can be quite effective against an advanced rectal carcinoma.

This case report presents an unusual case of primary IUD-associated ovarian actinomycosis, which spread to the sigmoid causing intestinal obstruction. A 43-year-old gravida 3, para 2, had her 1st IUD from 1978-80 (Gyne-T) and her 2nd IUD from 1980 to October 1983 (Multiload). Right lower abdominal pain led to hospitalization in May 1983. A tender nodular mass was palpated in the left pelvic area. Laboratory results confirmed the presence of inflammation. Rapid improvement followed a course of laxatives and cephalosporin antibiotics, and the patient was discharged with the diagnosis of acute sigmoid diverticulitis. 2 months later, a double contrast examination of the large intestine was done and showed severe narrowing of the sigmoid colon over a distance of 12 cm and occasional sharp recesses. Colonoscopy showed a spastic stricture of the sigmoid with massive edema of the otherwise intact mucosa at 18 cm. Computer tomography of the abdomen showed a large, focally cystic infiltrative mass in the pelvis with congestion and displacement of both ureters as well as bilateral hydronephrosis, predominantly on the right side. The descending colon was congested. The patient was readmitted to hospital with the tentative diagnosis of ovarian cancer when her general condition deteriorated. She complained again of abdominal pain in the right lower quadrant and alternating diarrhea and constipation. Pyrexia and the hematological findings suggested sepsis. The pelvis contained a predominantly leftsided nodular mass and a brown fetid discharge was coming through the cervix. The IUD was removed and treatment with ampicillin and clindamycin was started with rapid improvement in the patient's condition. Obstruction with extreme distention of the colon required emergency laparotomy. An inflammatory mass was found in the pelvis consisting of a right-sided ovarian tumor, bilateral hydrosalpinges, and a tightly encased sigmoid colon. The dilated caecum had a large necrotic area in its wall which necessitated caecostomy and double-current sigmoidostomy after subtotal hysterectomy and bilateral salpingo-oophorectomy. The patient made a good recovery. As recently as the 1950s, primary pelvic actinomycosis was a rarity. In the last 4 years alone, 20% of all reported cases of actinomycosis involved the female genital tract. The percentage of cases found among IUD users has been continuously increasing and in the last 2 years all published cases were IUD users. The presence of actinomyces in vaginal smears always is indicative of the presence of a foreign body, most commonly and IUD.

Melanosis coli was diagnosed histologically in colon biopsies of 45 patients with prolonged administration of anthraquinone laxatives. Colonoscopies performed for increased constipation, abdominal pains, or distention disclosed discoloration of the mucosa in only 14 patients. Radiographic studies revealed motility disorders of the colon. In several cases, a circular stenosis occurred at the junction of the colon and the sigmoid, simulating a tumor. Electron microscopy showed abnormalities of the absorptive epithelial cells. The lamina propria contained pigment-laden macrophages, plasma cells, and several nerve fibers in different stages of degeneration. The most striking changes of autonomic nerve elements occurred in patients with the most serious motility disorders.

Tumors of the posterior fossa presenting orthostatic hypotension are rare and only nine cases have been reported so far. The locations of almost all these tumors were near the fourth ventricle and three of them were hemangioblastoma. A case of a tumor of the fourth ventricle showing autonomic disturbances mainly composed of orthostatic hypotension is reported. A 42-year-old male was admitted to the Department of Neurology of Chiba University Hospital on June 25th, 1981 because of three years' history of autonomic disturbances including orthostatic syncope, impotence, urinary disturbance and bowel dysfunction such as vomiting, diarrhea and constipation. He also complained of weight loss and staggering of gait to the left side. On admission, the patient was emaciated being 50 kg in weight and 172 cm in height. Neurological examination revealed hippus of bilateral pupils in light reflex, saccadic eye movement, slightly hypoactive deep tendon reflexes, mild terminal oscillations in bilateral finger-to-nose test, oscillation in the left heel-to-knee test, staggering tendency of gait to the left, slightly impaired tactile and thermal sensations in distal parts of the legs. Autonomic disturbances were showed by orthostatic hypotension (BP 104-50 in supine and 70-40 in sitting position), impotence, weight loss, anorexia, decrease of sweating, spontaneous yawning and loss of sensation of bladder fullness. About 5 weeks after admission, he began to complain of temporal headache and showed impairment of memory, drowsiness, paroxysmal apnea and papilledema.(ABSTRACT TRUNCATED AT 250 WORDS)

Three cases of small bowel lymphoma in young homosexual men are presented. All three had acquired immune deficiency syndrome as demonstrated by demography, sexual history, cachexia, opportunistic infections by Cytomegalovirus, Pneumocystis carinii, atypical Mycobacterium, Candida, and/or evidence of immune deficiency, such as skin test anergy, lymphopenia, inversion of T-helper/T-suppressor ratio, and diminished lymphocyte response to either phytohemmaglutinin or pokeweed mitogen. All had peripheral and/or abdominal lymphadenopathy, and gastrointestinal symptoms, e.g., diarrhea, spasms, constipation, and oral candidiasis. The diagnosis of lymphoma was made at laparotomy in all cases. All three had complete removal of localized tumor (stage Ie or IIe), yet died within 6 months of surgery and/or chemotherapy. Thus gastrointestinal complaints may not always be related to "gay bowel" syndrome, or other infectious diseases in patients with acquired immune deficiency syndrome. Small intestinal lymphoma should be added to the list of neoplasms to which this group is susceptible.

A case of leiomyosarcoma of is reported. A 78-year-old man was admitted with a history of constipation and deformation of the stools. Barium contrast study and sigmoidoscopy showed a submucosal tumor of the rectum. On computed tomography and angiography, the tumor was suspected of being leiomyosarcoma. Abdominoperineal resection was performed. Microscopic examination revealed a leiomyosarcoma of the rectum and widespread lymph node metastases were found. Leiomyosarcoma of the rectum is an uncommon tumor. In our country, 89 cases have been reported. Six had lymph node metastases initially and another six subsequently. We have referred to the literature on leiomyosarcoma of the rectum.

A case of multiple endocrine neoplasia, type 2b, is reported presenting with weight loss, neck masses, and constipation. A medullary thyroid carcinoma was found to be present together with a megacolon. In this syndrome, the diagnosis of the thyroid tumor is rarely made before it is well established; hence an appreciation of the accompanying gastrointestinal symptoms and signs may lead to early diagnosis. The case had many classical features, such as ganglioneuromata involving the tongue, lips, and eyelids and typical biochemical findings. However, several unusual findings were present, such as the absence of any skeletal abnormalities, an acute onset of constipation, and the presence of bony metastases and the case is reported to illustrate the complexity of this uncommon entity.

A phase II study of Vindesine (VDS) was carried out in 20 patients with carcinoma of the lung (14 adenocarcinomas, 3 squamous cell carcinomas, 2 large cell carcinomas and 1 small cell carcinoma), and in 18 patients with metastatic pulmonary tumor (primary organ: 4 colons, 2 uteri, 2 lungs, one each tongue, pharynx, maxillary sinus, esophagus, mediastinum, bile duct, pancreas, kidney, rectum and sarcoma). VDS was given weekly by i. v. push at a dose of 3 mg/m2. Patients should be given at least three times of VDS for eligibility. Of 18 evaluable patients with carcinoma of the lung, 3 patients with adenocarcinoma showed a partial response. Response rates were 17% for patients with carcinoma of the lung, and 25% for 12 patients with adenocarcinoma. Two responders (uterine cervical carcinoma and mediastinal embryonal carcinoma) were observed in 14 evaluable patients with metastatic pulmonary tumor. In addition, one patient with metastatic maxillary sinus tumor showed a minor response. Major hematologic toxicities of VDS were leukopenia (less than 4000 cells/mm3--92%, less than 2000 cells/mm3--28%), anemia (less than 10.0 g/dl, 38%) and thrombocytopenia (less than 10 X 10(4) cells/mm3, 11%). Major non-hematologic toxicities were numbness (24%), constipation (11%), anorexia (21%), fever (16%) and liver dysfunction (21%). The dose limiting factor of VDS was leukopenia.
