A total of 10 cases of surgically resected intestinal tuberculosis specimens was subjuected for analysis of its macroscopic characteristics. Intestinal tuberculosis was broadley classified into the ulcerative type (4 cases), ulcero-hypertrophic type (3 cases) and mixed type (3 cases) on the basis of its gross features. The ulcerative type was characterized by multiple, segmental lesions of napkin-ring stricture with variable length of uninvolved mucosa, secondary to the circumferential or annular ulceration. Various forms of relatively superficial ulcers were also scattered. Their ulcer beds were rather granular, being covered with a necrotic detritus although the ulcer margins were relatively well defined with areas of some nodularity. The ulcero-hypertrophic type affected the ileocecal region and ascending colon in a tubular form by segmental thickening of the wall. The diseased segment of mucosa appeared cobble-stone, represented by coalescence of irregular ulcers and hemorrhage. There were scattered small ulcers in the separate portions of terminal ileum. The macroscopic distinctions between the intestinal tuberculosis and Crohn's or ischemic enterocolitis were presented in detail.

Calcification and ossification of colon cancer is frequently encountered, especially in the mucinous carcinoma. However, cartilage formation or enchondral ossification has rarely been described in human colon cancer. This report describes a case of a 59-year-old man with retroperitoneal metastasis of mucinous adenocarcinoma of colon, which showed a widespread heterotopic ossification through membranous or enchondral ossification. The ossification appeared in apposition to tumor cell nests and in the organized mucin pool. In our knowledge, this is the first case showing enchondral ossification in gastrointestinal carcinoma in Korea.

Although the reported number of malignant lymphoma of the thyroid has been increased, primary malignant lymphoma of the thyroid associated with chronic lymphocytic thyroiditis has been sporadically reported since its first description by Graham in 1931. The apparent coexistence of these two conditions has undoubtedly been noted by other observers. And they suggested that malignant lymphoma of the thyroid might arise from the lymphoid tissue ina wide variety of preexisting thyroidal disease. This report was made to record a case of primary thyroid lymphoma recently seen in this department with special emphasis on the associated thyroiditic changes in the uninvolved portion of the gland, which suggest the antecedent presence of chronic lymphocytic thyroiditis.

Vascular injury is a serious but rare complication of hip procedures. Most of vascular complications reported in articles occured in vessels around hip joint and femoral artery. To date, report of popliteal artery occlusion during or after total hip arthroplasty was absent. The authors have experienced one case of popliteal artery occlusion after total hip arthroplasty. It was suspected that the cause of occlusion of this particular case was a excessive maneuvering of limb during operation and then, artheromatous plaque fracture or thrombosis made occulusion in popliteal artery. Angiographic embolectomy using a catheter was performed and circulation of limb was recovered. To reduce the risk of vascular complications after total hip arthroplasty procedure, we recommend a thorough evaluation of lower extremity circulation in risky patient. And if a vascular insult is suspected either during or soon after the procedure, then a vascular consultation with arteriography including popliteal artery should be obtained urgently. Delay in treatment could result in a deleterious outcome.

Pheochromocytoma is originated from chromaffin cell of sympathetic nervous system and associated with other disease, such as neurofibromatosis, duodenal carcinoid, medullary thyroid cancer and parathyroid adenoma. Especially, pheochromocytoma is developed more than 50% in neurofibromatosis associated with hypertension. In such cases, several clinical features documented as more frequent bilateral phochromocytoma, more associated with other neuroendocrine tumors and thus more poor prognosis. We can observe the sustained hypertension despite of surgical resection of tumors in pheochromocytoma cases. One of the possible reason of post operative sustained hypertension is the pheochromocytoma originated from minor organ of Zukerkandl that was not resected during operation. Untreated or delayed treated cases with pheochromocytoma were often expired by complication of hypertension such as cerebrovascular hemorrhage, myocardial infarction, etc. Thus, in neurofibromatosis with hypertension, screening of pheochromocytorna is very important for the early detection of tumor and more favorable prognosis. Recently, We experienced a case of neurofibromatosis associated with bilateral pheochromocy-toma expired by cerebral hemorrhage during operation, so we report the case with literature review.

Melanosis duodeni is an uncommon pathologic condition characterized by diffuse small black spots on the first and second portions of the duodenum. It occurs predominantly in elderly patients and is linked to chronic renal failure, use of antihypertensive drug and oral iron supplementation, and/or presence of gastric hemorrhage. We report a case of melanosis duodeni in a 60-year-old woman diagnosed with hypertension 20 years ago and chronic renal failure 6 years ago. She has taken antihypertensive drugs for many years. On endoscopy, speckled black pigmentation of duodenal mucosa was detected. Microscopically, this duodenal lesions showed numerous coarse pigments in macrophages confined within the lamina propria. By ultrastructural study, macrophages contained electron-dense granules admixed with lipofuscin-like material in residual bodies.

There are considerable discrepacies between clinical symptoms and imaging diagnosis in the localization of the responsible radiculopathy. The purposes of this study are to analyzed the dynamic alteration of contrast filling of the spinal nerve sleeves during positional changes and to determine how the abnormalities of nerve sleeves no lateral bending A-P views correlate with sciatica. The criteria indicationg the root abnormality in functional myelography were (1) bad filling of ipsilateral root to sciatica and (2) good filling of contralateral root compared with those in neutral A-P view. Of total 77 patients, 67 had radiculopathy and 10 had no radiculopathy. In 23 (34.3%) of 67 patients with radiculopathy and 6 (60%) of 10 patients with no radiculopathy, their clinical symptoms well correlated with conventional myelographic findings. However, in 35 (52.2%) of 67 patients with radiculopathy and 6(60%) of 10 patients with no radiculopathy, their symptoms well correlated with functional myelographic findings. This study suggests that the functional myelogaphy using both lateral bending A-P views can be used as a complementary tool in the evaluation of the radiculopathy.
