Cytologic features of inflammatory pseudotumor of the lung have not been described frequently. We report fine needle aspiration cytologic(FNAC) finding of a case of inflammatory pseudotumor misdiagnosed as adenocarcinoma in a 63-year- old man. The FNAC displayed a mixture of histiocytes, myofibroblasts, pneumocytes, and plasma cells. Some histiocytes and myofibroblasts had large nuclei with irregular nuclear membrane and prominent nucleoli, which mislead the diagnosis of adeno- carcinoma on FNAC. The heterogeneous cell population is the unique cytologic features of inflammatory pseudotumor, which are helpful to distinguish it from other circumscribed benign and malignant lesions. Familiarity with these features is essential to avoid misdiagnosis and possible overtreatment.

Dissociated vrtical deviation(DVD) is frequently associated with infantile esotropia. It is hard to find DVD before surgery for esodeviation, and usually found after surgery. We studied the occurrence of DVD in 176 patients who had had horizontal rectus muscle surgery for the correction of infantile esotropia and followed up for 6 months or more. DVD was seen in 78 patients(44.3%), preoperatively in 27 patients(34.6%) and postoperatively in 51 patients(65.4%). Among 51 patients with DVD after surgery, DVD occurred in 24.0% of patients with preoperative angle of esodeviation less than 50 PD and in 44.6% of patients with preoperative angle of esodeviation more than 51 PD(P<0.01). Most of them(25 of 51 patients) developed DVD within 6 months after esodeviation surgery, however, 12 patients were noted to develop even after 2 years. This shows that we need long term follow-up for the detection of DVD. The occurrence of DVD was not influenced by the time of surgery for esodeviation(P>0.05). Inferior oblique overaction(IOOA) was accompanied with DVD in 71.8% and occurred without DVD in 28.6%. This study revealed postoperative DVD developed more in large angle esotropia such as deviation angle greater than 51 PD, and IOOA was frequently accompanied. The result suggests that in large angle infantile esotropia with mild IOOA and DVD or fundus extorsion we may need the preventive correction of DVD and IOOA.

Acinic cell carcinoma is a rare salivary gland carcinoma, usually being found in the parotid gland and is uncommon in the other major and minor salivary glands. The tumor cells consist of either serous or mucous acinar cells with few ductal or myoepithelial cell elements. The tumor is a low-grade malignancy with slow growth potential. Surgical therapy depends on tumor size and the extent of infiltration into neighboring tissues. Superficial parotidectomy or total parotidectomy is the initial method of therapy in case of acinic cell carcinoma on parotid gland. When regional neck lymph nodes are involved, the operation is combined with a neck dissection, or with radiation therapy. In the short follow up period, acinic cell carcinoma has good prognosis with 5 year survival rate after surgery is over 80%. In the long-term follow-up, however, there is a tendency to increase in recurrence or metastasis. We experienced a case of acinic cell carcinoma of the parotid gland in a 57-year-old female, so we report it with literatures review.

Primary intraosseous carcinoma(PIOC) is defined as a squamous cell carcinoma arising within the jaw, having no initial connection with the oral mucosa. The squamous cell carcinoma within the bone can be presumably developed from residues of the odontogenic epithelium, therefore, it is seen in the jaw only. Metastatic carcinoma from another primary site should be excluded in the diagnosis of Primary Intraosseous Carcinoma. This is a case of 62-year-old man, who initially diagnosed as odontogenic cyst on maxilla, but its pathologic examination was diagnosed as squamous cell carcinoma with odontogenic cyst. We treated this patient with partial maxillectomy, modified radical neck dissection(mRND), and postoperative radiation therapy.

An attenuated classical swine fever virus (CSFV), Suri strain, is a va.iant derived from a vaccine virus, LOM strain. This study was performed to elucidate the molecular biologcal properties of CSFV Suri strain, and to obtain the basic data for molecular epidemiological approaches for the disease. The truncated form of gp55 gene without the C-terminal transmembrane domain, in size of 1,023bp, was amplified by RT-PCR and sequenced by dye terminator cyclic sequencing method, and inserted into BamHI site of pAcGP67B baculovirus vector, establishing a cloned pAcHEG plasmid. By the nucleotide sequences determined, 341 amino acid sequences were predicted. As compared the nucleotide and amino acid sequences of gp55 of Suri with the various CSFV, Suri strain showed the high homology over 99.1% with ALD and LOM strains, but comparably the lower homology with Alfort and Brescia. In comparison of amino acid sequence in variable domain of gp55 protein, the similar tendency of homology was observed. In hydrophobicity analysis, all of four CSFV strains revealed the analogous patterns of hydrophobicity. The numbers and locations of N-glycosylation site and cysteine residues in gp55 were analyzed, those of Suri strain being coincident with ALD and LOM strains. The results suggest that gp55 in Suri strain has the high similarity to those in ALD and LOM strains in terms of the nucleotide and amino acid sequences and the functional properties of gp55 protein..

Cellular schwannoma is a variant of schwannoma, and is diagnosed as malignant tumor in over one fourth of cases because of its cellularity, mitotic activity and the occasional presence of bone destruction. This tumor is a tumor with low malignant potential and usually occurs in peripheral nervous system, mainly in the posterior mediastinum and retroperitoneal space. But pelvic retroperitoneal cellular schwannoma is very rare. Recently, we experienced a case of pelvic retroperitoneal cellular schwannoma in a 42-year-old woman; in reporting the case a brief review of the literature is included.

PURPOSE: To assess the MR findings of siliconomas (silicone granulomas) in patients with interstitial silicone injection mammoplasty. MATERIALS AND METHODS: Women with interstitial silicone injection mammoplasty were referred for this study on the basis of clinical findings of palpable mass. Nine patients with 18 augmentated breasts underwent axial and sagittal MR imaging, and the results were analysed in terms of their size, shape, margin, signal intensity, enhancement pattern, distribution and adjacent parenchymal distortion. We undertook in-vitro MR imaging of silicone, paraffin, fat, and water, and then compared their signal intensities at each sequence. RESULTS: Siliconomas were seen as well-defined low-signal-intensity nodules at T1WI and high-signal-intensity nodules at T2WI. There was no demonstrable contrast enhancement. Where there was breast cancer in which heterogeneous signal intensity was observed at T1 -and T2WI, together with heterogeneous enhancement, siliconomas were well differentiated from the tumor mass. At in-vitro MR imaging of silicone, paraffin, fat and water, paraffin showed a very low signal intensitiy at all pulse sequences but silicone showed low signal intensity at T1-fat-suppressed T1WI and high signal intensity at T2-and water-suppressed T2WI. CONCLUSION: MRI allows clear differentiation of siliconoma from fat and fibroglandular tissue, and can therefore, reveal anatomical details and detect lesions in patients with interstitial silicone injection mammoplasty.

BACKGROUND/AIMS: Combined esophageal variceal ligation and sclerotherapy has been hypothesized to be more effective for the control of bleeding esophageal varices than ligation alone. The present study was to compare the combined therapy with ligation alone in terms of variceal eradication, rebleeding, complication and survival rates in patients with bleeding esophageal varices. METHODS: Thirty-eight patients with bleeding esophageal varices were randomly assigned to receive ligation alone in 20 patients or the combined therapy in 18 patients. The clinical and endoscopic characteristics of patients in the ligation group were similar to those of patients in the combination group. In the combination group, 1-3 mL of ethanolamine was injected proximal to each ligated site. Treatments were repeated every 2- to 3-month until varices were eradicated. RESULTS: No significant differences were found between the ligation and combination groups in variceal eradication rates (70% vs. 72%), numbers of endoscopic sessions required to achieve eradication (3.5+/-0.33 vs. 3.3+/-0.31), rebleeding rates (30% vs. 28%) or 2-yr cumulative survival rates (95% vs. 75%). There were significantly more complications in the combination group (25% vs. 89%, p=0.001). CONCLUSION: Ligation alone is recommended rather than the combined ligation and sclerotherapy because of its lower complication rates.
