Two unusual cases of metastasis of carcinoma to carcinoma are reported. The initial malignancies, an adenocarcinoma of the rectum and a duct carcinoma of the breast, were found to have metastasis to a clear cell carcinoma of the kidney. The various theories on the peculiar tendency for the renal cell carcinoma to be the most common host tumor for other primary carcinoma are commented upon briefly.

Tomography has played an important role in diagnosis of facial bone fracture. Nowadays, it still acts as ainevitable process in decision of adequate treatment in patient with facial bone fracture. At the Department ofRadiology, Hanyang University Hospital, 74 patients who have facial bone fracture, were observed and analyzed withsimple skull films, mainly skull A-P, lateral and Water's view, after comparison with tomographic findings. Theresults were as follows; 1. Male was in 90.5% incidence. Most frequent age distribution was 21 to 40 years andmarked 62.2%. 2. Most frequent cause of trauma was traffic accident as 41 cases and the next one was fall down as13 cases. Other cause were blunt trauma such as first, stone, heavy metal etc. and explosion. 3. Clinical symptomsand physical signs were painful swelling, abrasion, ecchymosis and subconjuctival hemorrhage in almost allpatient. 4. Fracture distribution was 22 cases in simple fracure and 52 cases in complex fractures which were 26cases in Tripod fractures, 14 cases in Le Fort fractures and 12 cases in combined complex fractures. 5. Theradiologic findings on tomography were opacity of orbit of P.N.S. 87.8%, regional soft tissue swelling 85.1%,displacement of bony fragment 56.8%, abnormal linear density in orbit or P.N.S. 48.6%, bony fragment in orbit orP.N.S. 47.3% change of size of orbit of P.N.S. 40.5%, foreign body in orbit or P.N.S. 16.2%, and others 27.0%.These radiologic findings of simple fracture were less than those of complex fracture. 6. Radiologic findings offacial bone fracture on simple films were analyzed after comparison with tomograhs. Detectable possibility ofobvious fracture lines such as cortical disruption or separation was 67.6% on simple filsm. Detectable possibilityof other radiologic findings on simple films were displacement of bony fragment 86.7%, abnormal linear density inorbit or P.N.S. 88.6%, bony fragment in orbit or P.N.S. 71.4%, opacity of orbit or P.N.S. 90.8%, change of size ororbit or P.N.S. 96.4%, regional soft tissue swelling 96.2%, foreign boy in orbit or P.N.S.41.7%. Others such asabsence or deformity of infraorbital foramen, subcutaneous emphysema or intraorbital air 40.0%. Thereforetomography is inevitably taken to correct diagnosis of facial bone fracture.

Primary signet ring cell carcinoma of the prostate is extremely rare and about 18 cases have been reported in the literature. We report two cases of primary signet ring cell carcinoma of the prostate, arising in 79-year-old and 65-year-old men. Both cases were the poorly differentiated adenocarcinoma of the prostate with many signet ring cells. Signet ring cells were positive for prostatic specific antigen and prostatic acid phosphatase but negative for neutral and acid mucins. In summary, the signet ring cell carcinoma of the prostate is a rare variant of poorly differentiated adenocarcinoma of the prostate. The orgin of the prostate should be considered in cases of metastatic signet ring cell carcinoma, particularly when the signet ring cells are negative for neutral and acid mucins. Prostatic specific antigen and prostatic acid phosphatase should also be performed to confirm the primary signet ring cell carcinoma of the prostate.

Intracranial tuberculomas have been reported occasionally, especially in Asia, though much decreased in recentyears. Those lesions can be diagnosed more easily and acurately using CT than conventional method, including angiography. Authors analysed CT findings of 21 cases, confirmed as tuberculoma, at Hanyang University Hospital from May 1979 to June 1983. The resuslts were as follows; 1. Of all 21 cases, multiple lesions were seen in 14 cases (67%) and single in 7(33%). 2. Of all 21 cases, lesions located only at supratentorial were in 19 cases(90%) and remained 2(10%) had lesions at both supra and infratentorial area. And temporal and parietal lobes were common location (65%) of all lesions. 3. In precontrast scan, density of tuberculoma showed largely isodense (68%)and others were slight high (29%) and low(3%). 4. All lesions were enhanced showed as homogeneous nodular (68%),ring-shaped(29%) and target shaped(3%). 5. All rings were continuous and thickness was largely uniform(67%), anddensity of center of the ring was mainly low(67%). 6. Edema was seen in 58% of all lesions: comparing with thesize of tuberculoma, edema size was smaller in 50%, lager in 33% and almost the same in 17%.

We report a case of disseminated cutaneous metastatic carcinoma from stomach carcinoma in a 66-year-old male who complained chiefly of widespread cutaneous nodules. He had been admitted to the Department of Internal Medicine for stomach carcinoma. A radiological examination revealed a diffuse stomach wall thickening from the fundus to the antrum, and enlargement of paraaortic and pericaval lymph nodes during an abodominal CT scan. The clinical findings manifested above may suggest cutaneous metastasis from stomach carcinoma. A histological examination of the skin and stomach biopsies showed atypical cells with pleomorphic, hyperchromatic nuclei and bubble-like cytoplasm, which are consistent with poorly differentiated adenocarcinoma. Immunohistochemical stainings showed that these cells were positive for epithelial membrane antigen (EMA), carcinoembryonic antigen (CEA) and low molecular weight cytokeratin.
