Mixed tumor of the skin (chondroid syringoma) is a rare benign tumor composed of epithelial elements intermingled with myxoid or cartilagenous stroma which is not separated by basement membrane. It had been believed to originate from the eccrine gland but recently, it was described to be of apocrine gland origin in case of showing apparent apocrine secretion. We report on a 63-year-old man with a tumor on the right upper eyelid showing typical microscopic features of mixed tumor of the skin. Many apocrine decapitation secretions were seen in tubular structures and follicular differentiations were also seen, which represents the common origin of folliculo-sebaceous-apocrine unit.

Blue nevus is a benign melanocytic neoplasm and represents itself usually as a solitary blue or blue-black papule. It rarely occurs as multiple lesions grouped in a circumscribed area. How-ever, non-grouped disseminated blue nevi are exceedingly rare. We report a patient with acquired multiple blue nevi that was distributed over the entire body discretely and showed an increase in the number of the nevi without any causal factors.

Mesenteric fibromatosis is a rare nonmetastasizing fi brous tumor, characterized by fibroblastic proliferation without evidence of inflammatory response or definite neoplasia. It appears at any age, but mainly in the second to fifth decades as incidence of two to four desmoid tu mor cases per 1 million people per annum. It is pseudoen capsulated and locally invasive and has a tendency to recur, but metastases are rare. It is more frequent with Gardner's syndrome(adenomatosis coli) in which 50% of them will appear as mesenteric fibromatosis. Trauma, especially that of previous surgery, has been associated with the subsequent development of desmoid tumor. The treatment of choice is a wide margin resection of the tumor. we experienced a case of mesenteric fibromatosis without Gardner's syndrome 2 years after appendectomy in a 31-year old man and recurred at 21 months after resection and report with a review of literatures. 6

An endobronchial metastasis is defined as a subsegmental or a more proximal central bronchial metastasis of a nonpulmonary neoplasm in the bronchoscopically visible range. However, the frequencies of endobronchial metastasis range from 2 to 50% of pulmonary metastases from extrathoracic neoplasms by a different difinition of an endobronchial metastasis. Primary neoplasms of an endobronchial metastasis including breast cancer, colon cancer, renal cell carcinoma, and ovarian cancer are relatively common. However, an endobronchial metastasis arising from thyroid cancer, parotid gland tumor, bone tumor, bladder cancer, and stomach cancer has only rarely been reported in the literature. Here we report a case of an endobrochial metastases from a hepatocellular carcinoma

PURPOSE: To evaluate the usefulness of echo-planar FLAIR imaging in various cerebral lesions as compared with fast FLAIR imaging. MATERIALS AND METHODS: We obtained consecutive fast FLAIR and echo-planar FLAIR images in 33patients in whom MR imaging had revealed ischemic infarction (n=11), acute infarction (n=5), brain tumor (n=3), other conditions (n=3) or no abnormality (n=11). On both sets of images, percentage contrast and contrast to noise ratio (CNR) were calculated for white matter-gray matter and white matter-lesion. RESILTS: White matter-gray matter percentage contrast and CNR were lower on echo-planar FLAIR imaging than on fast FLAIR imaging (percentage contrast, 19 +/- 2 % vs 28 +/- 3 %, CNR, 2.77 +/- 0. 5 vs 4.86 +/- 0.7). White matter-lesion percentage contrast on echo-planar FLAIR imaging was similar to or greater than that on fast FLAIR imaging; 75 +/- 12 % vs 45 +/- 11 % in ischemic infarction, 80 +/- 12 % vs 78 +/- 11% in acute infarction, and 121 +/- 25 % vs 102 +/- 15 % for tumors. White matter-lesion CNR was similar on both sets of images: 8.3 +/- 0.9 vs 7.9 +/- 0.8 in ischemic infarction, 11 +/- 1.5 vs 9.5 +/- 1.2 in acute infarction, and 24 +/- 4 vs 27 +/- 3 for tumors. Due to high susceptibility to magnetization, echo-planar FLAIR imaging showed image degradation at the interface of the paranasal sinus and adjacent to the temporal bone. CONCLUSION: Echo-planar FLAIR imaging may be a useful pulse sequence in the diagnosis of various cerebral lesions.

Gastric carcinogenesis has been studied in various aspects. Helicobacter pylori (Hp) infection and mutation of the p53 tumor suppressor gene have recently been argued to be important factors of gastric carcinogenesis. There have been many studies to determine the precise mechanism of how Hp is related to gastric cancer, but it is so far still unknown. We studied the relationship of Hp infection and p53 overexpression and tried to discover some significance in clinicopathologic factors such as age, sex, stage, site, differentiation and gross morphology. Ninety-six patients who were diagnosed with gastric cancer at Severance Hospital, Yonsei University Medical College from November 1995 to March 1996, and 96 control patients of non-ulcer dyspepsia (NUD) were studied by endoscopic biopsy of normal gastric tissue and cancer tissue. They also underwent the CLO (Delta West, Melbourne, Western Australia) test for Hp positivity and p53 immunohistochemical stain for p53 positivity. These data were analyzed for comparison with the clinicopathologic characteristics of gastric cancers. In conclusion, the differentiated group cancer had a significantly high Hp positivity and p53 positivity. There is a possibility that Hp infection and p53 tumor suppressor gene mutation might be significantly related in the gastric carcinogenic process of well- and moderately-differentiated adenocarcinomas, but further study is necessary to determine more direct clues on the carcinogenic roles of these factors.

The materials used in rhinoplasty can be divided into autogenous and alloplastic one. The advantages of autogenous materials such as bone, cartilage, dermofat are no postoperative rejection and good adaptation. They are also economical. But they are often limited in harvesting which entails additional morbidity. Many synthetic materials have been introduced in rhinoplasty. Silicone is popular material for augumentation, but that has disadvantage, such as infection, protrusion, foreign body reaction and showing. Porous high density polyethylene implant (Medpor(R)) present an alternative to autogenous material as they allow of fibrovascular ingrowth, leading to stability of the implant and decreased rates of infection. We reviewed the data from 10 consecutive patients with foreign body injection on the nose who were operated in Dong-A University Hospital from May 2001 to July 2003. Our application is that the necessity of enough rigidity to provide structural support and enough volume to provide augumentation. Patient follow-up ranged from 1 month to 2 years. We can achieve 7 good satisfaction patients and 3 fair satisfaction patients. No complications were reported, such as infection, secondary deformity and exposure of implants. Medpor(R) is useful in corrective rhinoplasty, especially in the cases with foreign body injection, because it can provide structural support and augumentation with enough rigidity.

Tetanus is rare in Korea due to the introduction of vaccination programs and the advancement in public health. Its common signs are trismus, voice disturbance, neck stiffness, and difficulty in swallowing, etc. A 56 years old man was injured by grasping a high voltage electric cable. After the accident, he fell down on a steel plate and had a head trauma. When he visited Emergency Department, there was multiple electric burn wound on left arm and left facial area. He was hospitalized on a department of neurosurgery, because intra cranial hemorrhage was presumed. 12 days later, he was referred to department of OMFS with developed painful masseter spasms and trismus. That night he violently bit his tongue with his denture. Because masseter muscle and temporal muscle constriction was involuntary, tongue was lacerated and denture was distorted. At first we supposed that the symptom was related with neurologic disturbance following head trauma or electric shock. But it was revealed that trismus was caused by tetanus on an electrophysiological test. By using mechanical ventilation and administration of tetanus immunoglobulin, muscle-relaxant, and sedatives at ICU, symptoms had subsided (4-weeks). Because tetanus is rare disease, we rarely suppose tetanus infection to be a cause of a trismus. Especially it is more difficult to diagnose in patient who has head trauma, burn and neurologic problem as in this case.
