A 44-year old woman had pain in the epigastric region under the thorax aperture on the left side 6 weeks prior to admission. Her doctor had prescribed Rewodina and Myocuran without success. Then she suffered circulatory collapse twice. Upon hospitalization, she experienced colicky upper abdominal pain and vomiting. She had been taking oral contraceptives (OCs) for 13 years. Spontaneous liver rupture attributable to
adenoma
was suspected, based on computer tumograms, and laparotomy bore out the suspicion. However, the cause was peliosis hepatis: the left half of the liver was more altered than the right, and a 10cm parenchyma defect was located under the left lateral liver lobe to which a large intrahepatic cavity filled with coagulum was attached. There was a copious amount of blood in the upper abdomen and another
hole
was filled with old blood. Partial liver resection was performed. The patient returned 3 weeks after recuperation because of fluctuating inflamed swelling developed on the right side. An incision was made to remove the abscess, but instead of finding pus, massive bleeding ensued whose source could not be located; it was squelched by tampons. Removal of the tampons 7 days later started another rupture with signs of liver insufficiency, and the patient died. Although the role of OCs in inducing liver changes has not been conclusively proven, the fact that she had taken OCs for years without any medical supervision seems to implicate this contraceptive method.

In order to determine the effect on the respiratory system of long-term inhalation of chromic acid in electroplating, histopathological examination was performed on mice (ICR, female, n = 50) exposed to chromic acid mist for 12 months (30 min/d, 2 d/wk), by using the authors' miniaturized chromium electroplating system. After 12 months' exposure, the mice were kept for 6 months without exposure. In the upper respiratory tract, round perforations were found in the nasal septum in 6 mice that were sacrificed or died after 10 months' exposure. The perforations were located near the point of the septum, the thinnest part of the nasal septum, and were of pin-
hole
sige. On the epithelium of the trachea and bronchus, loss of cilia, proliferation of goblet cells or basal cells, and squamous metaplasia were observed in almost all of the exposed mice. These changes appeared to be more advanced in mice exposed for a longer period. In the lung, development of benign
adenoma
was observed in one mouse in the 6- to 9-months' exposure group, in three in the 10- to 14-months' exposure group and in one in the group examined after 15 to 18 months. Furthermore, adenocarcinomas were found in two mice, one of which died at 17 months and the other was sacrificed 18 months after initiation of exposure. In conclusion, the finding that adenomas and adenocarcinomas were observed in mice exposed to chromic acid mist suggests the need to give careful attention to the possibility of respiratory cancers in chromium electroplating workers.

The vast majority of gastrointestinal polyps are hyperplastic polyps or adenomas, their identification is possible bioptically.
Adenomas
are precancerous lesions, smaller ones with a diameter minor than 1 cm show invasive carcinoma in nearly 1%, in major polyps the percentage of invasive carcinoma will be 10% and more.
Adenomas
should therefore be removed with electrocautery snare (endoscopic polypectomy). Hamartomatous polyps (Peutz-Jeghers and juvenile polyps) are much less frequent, and mainly met with the Peutz-Jeghers syndrome (PJS) and familial juvenile polyposis (FJP). Hamartomas may bleed or induce obstruction or invagination. Adenomatous and malignant structures may be found within hamartomas, endoscopic polypectomy of these polyps is therefore mandatory. Mesenchymal (submucosal) polyps--leiomyoma, neurinoma--may only be identified by button-
hole
biopsy or after polypectomy; smaller submucosal polyps (up to 2 cm diameter) can be removed endoscopically, if strangulation is possible; the others should be removed during operation. Carcinoid tumors are rare within the upper and lower gastrointestinal tract, those with a diameter up to 1 cm should be removed by endoscopic polypectomy, larger ones have to be operated on.

A parathyroid
adenoma
was wrongly localized by pinhole Tc-99m sestamibl scintigraphy to the anterior mediastinum near a lower pole of the thyroid gland. After a failed surgical attempt to resect the
adenoma
, the patient was re-imaged with a parallel-
hole
collimator and SPECT. The
adenoma
was found to be near the heart, anterior to the carina. The pinhole findings were replicated using a phantom and measurements obtained from a CT of the chest. By placing the pinhole collimator at the sternal notch level, the lesion was correctly located deep in the chest. Moving the pinhole collimator cephalad or tilting the collimator toward the feet, maneuvers sometimes needed to clear the chest in large patients, projected the lesion closer to the sternal notch. Scintigraphy with a parallel-
hole
collimator is recommended and SPECT should be considered when the lesion is located below the sternal notch and when a lesion is not detected, despite the clinical and biochemical diagnosis of hyperparathyroidism.
