Endolymphatic sac tumor is rare, locally aggressive hypervascular tumor of papillary structure, arising from the endolymphatic duct or sac in the posterior petrous bone. We present four cases with this tumor. Two patients were male and the other two were female. Age of each patient was 15, 52, 58, and 67 years. Three patients presented with progressive hearing loss and sustained vertigo for months to years and another one was referred for the tumor detected in routine medical check-up. Preoperative embolization was performed in 3 patients. Complete excision of the tumor was achieved in all patients using translabyrinthine or retrosigmoid approach. Herein, we describe the clinical and radiographic features, surgical treatment and pathologic findings with a review of the literature.

Focal Segmental Glomerulosclerosis(FSGS) is one of the underlying pathology of congenital and infantile nephrotic syndrome. There is no ultimate curative treatment except renal transplantation. We have experienced a case of infantile nephrotic syndrome In a 10 month old boy who presented with proteinuria and hematuria. His elder brother also suffered from nephrotic syndrome and died at the age of 18 months due to sepsis. We have diagnosed this patient with clinical manifestations, laboratory data and pathologic findings which was done by open renal biopsy. The patient expired 54 days after admission because or progressive uremia and sepsis.

The reduction in the amount of asialoglycoprotein (ASGP) receptor, which resides exclusively on the plasma membrane of functioning mammalian hepatocytes, as a consequence of hepato-cellular damage has been demonstrated in various pathologic conditions of the liver. Galac-tosylated human serum albumin (GSA) is a newly developed receptor-binding agent, specific for the ASGP receptor. Tc-99m GSA binds quantitatively to liver ASGP receptors and the rate of accumulation in the liver is dependent on hepatic function represented as the amount of receptor, as well as the amount of ligand injected, its affinity to the receptor and the hepatic blood flow. The findings of Tc-99m GSA scintigraphy were reported to reflect the hepatic function of the patients with large hepatic tumors, obstructive jaundice, acute and chronic liver disease. Tc-99m GSA scintigraphy is an easy and reliable test and has the clinical potentials to evaluate the liver function in the patients with hepatic disorders.

Calcific tendinitis is a common condition with characteristic clinical and radiological findings. Although we do not know which condition initiated the pathologic cascade, we present a rare case of calcific tendinitis of the long head of the biceps brachii at its origin, associated with a SLAP lesion. The calcium deposit was removed and the SLAP lesion was repaired with a suture anchor arthroscopically.

Idiopathic small bowel ulceration distal to the duodenum is rare. Less than 5 % of the reported cases were in children. In the majority of the patients, a single ulcer of unknown cause is found in the jejunum or ileum. The diagnosis is difficult and usually made at the time of surgical exploration for complications, such as perforation, hemorrhage or obstruction. We treated a pediatric patient with perforation of an idiopathic ileal ulceration. The child was an 11-year-old boy who sustained blunt abdominal trauma. The involved ileal segment was resected. Pathologic findings were compatible with idiopathic small bowel ulceration. The clinical and pathological aspects of idiopathic ulcerations are discussed, and the literature reviewed.

Following the introduction of a novel pathological concept of usual interstitial pneumonia (UIP) by Liebow and Carrington in 1969, diffuse interstitial pneumonia has evolved into UIP, nonspecific interstitial pneumonia (NSIP), and interstitial lung abnormality (ILA); the histopathological and CT findings of these conditions reflect the required multidisciplinary team approach, involving pulmonologists, radiologists, and pathologists, for their diagnosis and management. Concomitantly, traction bronchiectasis and bronchiolectasis have been recognized as the most persistent and important indices of the severity and prognosis of fibrotic lung diseases. The traction bronchiectasis index (TBI) can stratify the prognoses of patients with ILAs. In this review, the evolutionary concepts of UIP, NSIP, and ILAs are summarized in tables and figures, with a demonstration of the correlation between CT findings and pathologic evaluation. The CT-based UIP score is being proposed to facilitate a better understanding of the spectrum of pulmonary fibrosis, from ILAs to UIP, with emphasis on traction bronchiectasis/bronchiolectasis.

Purpose: Pachydermoperiostosis is a rare hereditary disease characterized by finger clubbing, periosteal reaction, and pachydermia. The underlying pathogenic mechanism of this disease remains unclear. This disease is known to be associated with a variety of diseases such as cranial suture defect, bone marrow failure, hypertrophic gastropathy, Crohn's disease, and female escuchen. Methods: A 50-year-old male had digital clubbing of both hands, coarse hypertrophic skin changes of face, progressive thickening and furrowing on the scalp(cutis verticis gyrata), persistent pain in the limbs and joints. Other cutaneous features include moderate blepharoptosis, pole-like lower legs and feet. Results: We performed surgical excision for hypertrophic skin change of scalp because of frequent eczematous skin change, severe itching sensation and cosmetic problem. Diagnosis is confirmed by bony proliferative periosteal reaction, pathologic findings, and characteristic clinical findings. Conclusion: Pachydermoperiostosis is manifested by finger clubbing, and hypertrophic skin changes causing coarse facial features with thickening and periosteal bone formation. We experienced a case of pachydermoperiostosis. Brief review of related literature is given.

Sweet's syndrome is characterized by clinical symptoms, physical features, and pathologic findings which include fever, neutrophilia, tender erythematous skin lesions, and a diffuse infiltrate of mature neutrophils. This is a report of our experience of Sweet's syndrome with parotitis. A 57-year-old man initially presented with tender swelling on the right cheek similar to parotitis. His symptoms relapsed despite the use of an oral antibiotic agent for 3 weeks. He additionally presented with erythematous papules and plaques on the periocular area and dorsum of both hands. Histiopathologic findings on punch biopsy of the right dorsum of the hand showed superficial perivenular histiocytic infiltration without vasculitis. We confirmed this as histiocytoid Sweet's syndrome and used systemic corticosteroid. After initiation of treatment with systemic corticosteroids, there was a prompt recovery from both the dermatosis-releated symptoms and skin lesions. Sweet's syndrome should be considered in patients with therapy-refractory parotitis and unclear infiltrated nodules. We present a confusing case who initially appeared to have parotitis but turned out to have histiocytoid Sweet's syndrome.

Since tuberculosis was a common pulmonary disease in Korea, Aspergillosis was easily misdiagnosed as tuberculosis and an acute form of Aspergillosis was misinterpreted as pneumonia because of their similarities in the X-ray findings. This investigation is designed to illustrate the clinical features and preoperative diagnosis and surgical role in the management of this disease. In a retrospective review of operative cases from Jan. 1963 through Dec. 1983, 36 cases were analyzed. Peak age incidence lies in the 3rd decade [41.7%]. All cases had a history of treatment with antituberculous drugs under diagnosis of pulmonary tuberculosis and the most common chief complaint was hemoptysis [69.5%]. Only nine cases [25%] showed cavitary lesions with mycetoma and preoperative sputum study for fungus showed low positive valve [42.3%]. Anatomical location of lesion was located mainly upper lobe [66.7%] and most of cases were managed by lobectomy. We experienced 7 cases of complication; they were postoperative empyema, hepatic failure, esophageal varix bleeding. Postoperative pathologic findings showed that 29 cases [80.5%] were combined with tuberculosis 3 cases were combined with bronchiectasis and 4 cases were not combined with other disease. In conclusion, when the patient has a longstanding history of pulmonary tuberculosis and has a hemoptysis, he must be suspected fungus super infection. Resectional surgery is the treatment of choice for symptomatic localized disease and needed resection in asymptomatic patient to prevent possible fatal sequelae in the future.

Non-Hodgkin's Lymphoma(NHL) is a malignant tumor that is derived from the lymphatic system. The most common symptoms of NHL are painless lymph node enlargement. However, we should not diagnose NHL by only fragmentary clinical symptom and radiologic finding because of the various lymphoma characters. We have treated a patient with such preoperative findings of Branchial cleft cyst. However, the pathologic diagnosis of the surgical specimen was diffuse large b-cell lymphoma.
