Primary gallbladder carcinoma is generally assumed as uncommon but dismal malignancy. Only sporadic studies about pathologic features of the gallbladder carcinoma have drawn pathologists attention especially in association with cholelithiasis. Currently, we have focused much on the role of metaplastic changes in diseased gallbladders including cholecystitis with or without cholelithiasis, and raised its implication in the development of benign or malignant neoplasm. The authors reviewed 34 cholecystectomy cases with primary gallbladder carcinoma, and their histologic findings were analyzed with reference to the association of metaplastic changes both in tumor and adjacent nonneoplastic mucosal epithelium. Association with gallstones and metaplastic changes in the surrounding nontumorous mucosa is more frequent in intestinal typen than in non-intestinal type (P<0.05). Gallstones may play a role of irritant stimuli to the gallbladder mucosa which can be eventually reconstructed with more resistant cell type. And the subsequent increase in absorptive capacity and accumulation of carcinogenic substance may result in malignant transformation of (reserve) cells in replication zone. At this time we can assume that association of cholelithiasis and presence of metaplastic changes are in parallel relationshop in intestinal type adenocarcinoma. Intestinal type adenocarcinomas are usually papillary (72.7%) especially in superficial portion, but deeper area also shows infiltrative growth focally. This finding is comparable to intestinal type gastric carcinoma which represents frequently a polypoid and papillary growth pattern. With these results, as in the gastric carcinoma it is strongly supported that intestinal metaplasia may play a major role as a precancerous lesion in a minor group of the gallbladder adenocarcinoma. Controlled prospective study on biological behavior of intestinal type adenocarcinoma should be followed with more cumulative cases.

Seventy five cases of squamous cell carcinoma of the uterine cervix, invasion depth of which was less than 5 mm from the basement membrane, were reviewed during a period of 9 years from 1975 to 1983 at SNUH and investigated clinicopathologically by the following items; 1) lymphnode metastasis 2) vascular invasion 3) recurrence 4) pattern of invasion 5) cell type. Following results were obtained. 1) Lmyphnode metastasis was demonstrated in 4 out of 75 cases (5.3%). One of them had stromal invasion to 1.3 mm and the other three to a depth of 3.1 to 5.0 mm. 2) Vascular invasion was seen in 5 among the cases (6.7%) and well related to the depth of invasion. Vascular invasion did not occur in tumors with 3 mm depth of stromal invasion. 3) Three patients were with recurrence, treated by postoperative radiation. The depth of stromal invasion was over 2 mm in all of them. 4) The pattern of invasion was confluent in 26 out of 28 cases (92%) whose stromal invasion were over 2 mm depth, while only 3 confluency of 27 cases (11%) invaded less than 1 mm depth. 5) There was no good relationship between the tumor cell type and the depth of stromal invasion. Based on the above results, it is concluded that diagnostic criteria of microinvasive squamous cell carcinoma of the uterine cervix is stromal invasion not exceeding a depth of 3 mm from basement membrane of surface or glandular epithelium.

PURPOSE: To determine if MR myelography (MRM) improves the interpretation of the severity of stenosis in patients with a multi-level lumbar stenosis. MATERIALS AND METHODS: Among the patients referred for MRI with MRM prospectively, 100 patients over 50 years old with multiple lumbar stenosis were enrolled in this study. The most severe stenotic level and the degree of stenosis at that level according to the extent of the remaining subarachnoidal space (1: normal to 50%, 2: over 50% but not a total block, 3: total block) were evaluated in a blinded manner by two observers. Conventional MRI (class A), MRM (class B) and MRI+MRM (class C) was evaluated independently and the interobserver and intraobserver reliability were assessed. RESULTS: In the selection of the most severe level and degree of stenosis, both observers showed a higher level of consensus with classes B and C than classes A and C. The interobserver k average values for the selection of the most severe level in classes A, B and C were 0.649, 0.782 and 0.832, respectively. In terms of the degree of stenosis, the average in classes A, B and C were 0.727, 0.771 and 0.784, respectively. The intraobserver k values for the above two items were the highest in class (B), followed by (C) and (A) in all observers and within the range of "almost perfect" (0.81< or =k< or =1) except for the selection of the level of one observer in clause A. CONCLUSION: MRM when used in routine practice can help improve the observer reliability in assessing the severity of stenosis in multiple lumbar stenosis.

Acinic cell carcinoma is a rare malignant tumor that accounts for 2%–3% of salivary gland tumors. Acinic cell carcinoma arising from the breast is extremely rare, with only approximately 70 cases reported to date. Owing to its rarity, previous studies have primarily focused on pathological findings. Herein, we present the clinical and radiological features of acinic cell carcinoma of the breast in a 33-year-old woman.

Tufted angioma is a rare benign vascular neoplasm that usually occurs in children. It appears as an erythematous, purplish, indurated papule or plaque on the trunk or neck. Although it can have variable clinical manifestations, the annular or serpiginous configuration of lesions resembling tinea infections has rarely been reported. A 47-year-old woman presented with an erythematous plaque enlarging by peripheral extension to form polycyclic or serpiginous figures on her left chin and buccal cheek for 7 months without any subjective symptoms. Tinea faciale was considered as the initial clinical diagnosis, but repeated KOH tests were all negative; therefore, skin biopsy was performed. Histopathology revealed discrete circumscribed foci of capillaries scattered throughout the dermis showing a cannon ball appearance, compatible with tufted angioma. Clinical features showed considerable improvement after 2 sessions of intense pulsed light and pulsed-dye laser (5 repetitions) without any complications. Herein, we report a rare case of polycyclic variant of tufted angioma, which developed in a woman in her 5th decade.

Ten cases with esophageal foreign body were treated surgically from July 1980 to October 1995 at the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. The mean age was 45.3 years, with a range from 25 to 71. Out of ten cases, 6 were female and four were male. Common symptoms were dysphagia, fever, foreign body sensation and neck pain. Three cases of foreign bodies were of fish bones, two of bubble package of drugs, one case of a beer bottle cap, one of a piece glass, one of a bathtub plug, one of chicken and one of a bean. The diagnosis was established by esophagography using a water soluble contrast material and esophagoscopy. Among of ten cases, two had esophageal stricture due to the ingestion of lye at a young age. One case had experienced psychological problems. All foreign bodies were removed by surgical procedures. Five cases were treated by cervical esophagostomy, one case by right thoracotomy, one case by retrograde bougienation through gastrostomy and two cases by cervical incision and drainage for cervical abscess. Three cases developed post operative esophageal leaks which healed spontaneously and transient hoarseness developed in one case. One case developed traumatic pneumothorax and subcutaneous emphysema which was treated by closed thoracostomy. There were no operative deaths.
