During the 7-year period (1987-1993) the authors treated nine girls on account of torsion of the adnexa. In six girls torsion of primarily unaltered adnexa occurred, in one girl torsion of an ovary enlarged by a cyst and in two torsion of the ovary affected with a benign tumour, a coetaneous teratoma. In seven instances the organ affected with ischaemic necrosis had to be resected. In two girls detorsion of the ovary was performed, according to a sonographic control examination, however, in one the affected ovary atrophied. In the discussion the authors deal with the diagnosis of torsion of the adnexa and the method of treatment. The authors consider ultrasonic examination of organs of the abdominal cavity and retroperitoneum a very suitable method in all cases of abdominal pain in childhood, as this method can greatly contribute to the diagnosis of acute abdominal and gynaecological attacks. During surgery they recommend to preserve adnexa with a doubtful vitality because there is certain hope that they will be saved. During the postoperative period they recommend the long-term follow up of girls clinically and by ultrasonographic checks. If pathological changes are detected on the preserved adnexa, they recommend early re-operation and elimination of the risk factor (cysts etc.). The operation should be supplemented by prophylactic fixation of the preserved adnexa if this fixation was not done already during the primary operation.

A series of 286 patients receiving surgical treatment for ovarian tumors at Song-klanagarind Hospital between January 1987 and June 1990 were reviewed. The most frequent diagnoses by age group were: cancer in 53 per cent of women > or = 50 yrs of age, endometrioma in 63 per cent of women 31-49 yrs of age and benign cystic teratoma in 49 per cent of women < or = 30 yrs of age. Mucinous ovarian tumors were the most common type of epithelial neoplasms. Abdominal pain was the symptom most frequently experienced in patients with benign ovarian tumors. The 95 per cent confidence interval for finding malignancy in women > or = 50 yrs, ascites > 500 ml and size of ovarian tumor > 10 cm was 47-99 per cent.

With the increasing use of ultrasonography (US) in children, abdominal cystic masses, many of them nonrenal, are being detected more frequently both before and after birth. Between 1986 and 1991, 20 predominantly cystic abdominal or pelvic masses of nonrenal origin were detected by US in patients less than 10 years of age. Ten of the 20 patients were neonates; in 5 of these the masses were detected antenatally. Pathological correlation was obtained for 16 of the patients. Six of the cysts were ovarian; two represented cystic teratoma, two exhibited torsion and hemorrhage, one was a giant simple cyst and one was a simple cyst with herniation. Six of the lesions were duplication cysts; two were found in the antral region, of which one was ulcerated and had perforated. In the remaining group of eight cysts, three were found in newborns; one represented colonic atresia and another was a choledochal cyst. Several of these nonrenal cystic masses were detected incidentally or in patients with nonspecific abdominal pain. US correctly predicted the location of the cyst and the diagnosis in most patients. In many of the patients the masses were complicated by other problems that required diagnosis and treatment.

A 76-year-old female was noted to have a rectal mass on evaluation for postmenopausal bleeding. There was no history of abdominal pain, constipation, or rectal bleeding. Flexible sigmoidoscopy revealed a 3-cm pedunculated rectal mass at 10 cm. Hair fibers were visible through the smooth glistening surface. At colonoscopy, the polyp was removed by snare polypectomy. Histology showed epidermal, mesodermal, and endodermal components diagnostic of benign cystic teratoma. Subsequent total abdominal hysterectomy and bilateral salpingo-oophorectomy revealed endometrial carcinoma and postmenopausal ovaries. Primary rectal teratoma is a very rare rectal mass that may present endoscopically. Since 1865, only 33 cases have been reported in the literature. Endoscopic photographs, histology, and a review of the literature are presented.

A case of carcinosarcoma arising within an otherwise benign cystic teratoma is reported. The patient, a 78 year old nulliparous woman, presented with right sided abdominal pain of short duration and subsequently underwent a bilateral salphingo-oophorectomy. Slicing of the left ovary revealed a unilocular cyst containing hair admixed with soft yellow material with a thin wall apart from a solid area at one pole. Extensive areas of necrosis and cystic degeneration were present within this mass. Histologically, the large cyst was a typical mature cystic teratoma, containing carcinomatous and sarcomatous elements. Mature cystic teratomas have been reported in association with a variety of malignant ovarian tumours such as mucinous cystadenocarcinoma and malignant germ cell neoplasms. Secondary malignant transformation within a dermoid cyst is a much rarer occurrence, estimated as less than 2% of all such lesions. Adenocarcinomas are the second most common malignancies arising within dermoid cysts. Sarcomas alone or in combination with squamous carcinoma have been described arising in a mature cystic teratoma. To the best of our knowledge, no case of sarcoma arising in association with adenocarcinoma has been described before.

A 28 year woman complained for a sudden abdominal pain with some of the classical signs of the acute abdomen. Since a bilateral ovarian mass was found at ultrasound examination, clinician decided that patient underwent a urgent surgery. At histology, this mass resulted to be a bilateral triphillic mature teratoma. A focus lined by endometrioid epithelium and embedded in the modified stroma of endometrial type, was found beyond the residual cortex of the left ovary. There was some fibrotic tissue separating the endometrial and teratomatous lesions. To our knowledge, these two diseases have never been reported as associated in literature, but this association has a clinical relevance because an endometriotic pathology can reveal a silent teratoma with bilateral ovarian localization.

A case of renal carcinoid tumour arising within a teratoma in a horseshoe kidney in a 23-year-old male is reported. The presenting symptom was abdominal pain, and bone tissue within the tumour was initially misinterpreted as a calyx stone, leading to unsuccessful attempts at extracorporeal shock-wave lithotripsia and percutaneous lithotripsia. This unusual tumour is over-represented in patients with horseshoe kidney and other congenital developmental renal defects.

Cryptorchid testis have a greater risk of malignant change than do normally descended testis. The undescended testis would also be susceptible to torsion by the mechanism of increase in testicular size. A 36-year-old man of torsion of malignant undescended testis is presented. He was diagnosed as having incarcerated inguinal hernia on his first visit to general surgeon due to acute left lower abdominal pain. At laparotomy, a 7.5 x 5.5 x 3.0 cm3, greyish tan color mass was found. The pathological diagnosis is choricarcinoma and teratoma, mixed germ cell tumor. We would emphasise that in any patient presenting with acute abdominal symptoms and an absent scrotal testis, the possibility of a complication of torsion of undescended testis should be considered.

Two cases of a parasitic omental teratoma which originated from an ovarian dermoid that underwent torsion, autoamputation and omental reimplantation are presented. A review of the literature revealed 23 additional cases of omental teratoma which occurred mostly in females. In some cases, the mature teratoma of the omentum showed histological evidence of ovarian stroma, and was associated with a dermoid tumor of the remaining contralateral ovary. It is generally believed that autoamputation and reimplantation of an ovarian dermoid cyst is the most common etiology of omental teratomas. Abdominal pain is the main presenting symptom of these tumors, and on physical examination a mobile abdominal or pelvic mass is often found. Both ultrasonography with colour flow Doppler and CT-scan are helpful in the diagnosis of dermoid tumors, but the correct diagnosis of omental localisation is extremely difficult. Mature omental teratomas may be treated by simple resection. The immature teratomas of the greater omentum, however, are potentially malignant tumors requiring postoperative chemotherapy and radiotherapy.

We present an unusual case in which a 36-year-old patient was referred for consultation due to increasing upper left abdominal pain at 35 weeks' gestation. Transabdominal ultrasonography disclosed an appropriate-for-gestational-age singleton, vertex-presenting fetus with normal anatomy. An unclear, complex, semisolid, semicystic mass was noted in the upper right abdomen. Due to the close proximity of the adnexal mass to the patient's abdominal wall, a high-frequency transvaginal transducer was applied transabdominally. Unlike the unclear images generated at conventional transabdominal ultrasonography, this application depicted a discrete mass with multiple characteristics consisting of calcifications, hair and fatty tissue, considered diagnostic of a mature cystic ovarian teratoma. The patient delivered spontaneously at 39 weeks' gestation. At 6 weeks' postpartum an elective laparotomy left ovarian cystectomy was performed and a mature cystic teratoma confirmed by pathology examination.
