Ultrasongraphy is a safe, noninvasive examination which should be the first procedure in the workup of apatient with a definite or suspected pelvic masses. The diagnostic schemes were derived from correlating the sonographic features with histomorphology in 230 surgically proven pelvic masses. Besides separating pelvic masses into the conventional categories of cystic, complex and solid, grayscale sonographic features of a pelvic mass canbe used to subcategorized these masses into a more useful differential diagnosis. The results are as follows; 1.The most characteristic finding of uterine myoma was midly to mederately echogenic uterine enlargement (90.7%)with a lobulated uterine margin (62.8%), and often less echogenic than the normal uterine echoes. 2. The typical ultrasonographic finding of H-mole was uterine enlargement with multiple small vesicular patterns of intrauterincontents(93%). 3. The most frequent finding of cystic teratoma was cystic mass with echogenic foci(48%), but the echogenic appearance of the lesions was extremely variable. 4. The ultrasonographic findings of ectopic pregnancywere adnexal mass(comlex or cystic), decidual proliferation of the uterus, enlargement of uterine size, fluid incul-de-sac, deveiation of uterus by adnexal mass, and psuedointrauterine appearance. 5. Ultrasound provided information leading to the correct diagnosis in 57% of cases, contributory data in 21.3%, and non-specific information in 10.4%. Errors occured in 3.9% and false-negative in 7.4%.

The diagnosis of acute undifferentiated leukemia is made when the leukemic cells cannot be classified using morphologic and cytochemical analyses, and do not express myeloid or lymphoid antigens. Trisomy 13 is a rare primary chromosomal abnormality in acute leukemia and associated with lineage inconsistency and poor prognosis. We report a rare case of acute undifferentiated leukemia showing negativity in periodic acid-Schiff (PAS) and myeloperoxidase (MPO) without any lineage-specific cell surface marker expression and having trisomy 13. The patient was a 72- year-old male who visited our hospital because of anemia and general weakness. On examination, leukocytosis with proliferated blasts (76%) in peripheral blood was noted. Bone marrow aspirate showed blast proliferation (74%) with morphologically hand-mirror type. The blast expressed CD34 (96%) and HLA-DR (76%) in immunophenotyping. Cytogenetic study of bone marrow cells showed 46,XY,+13,-21[15]/46,XY[5]. Induction chemotherapy was failed and differentiation to monocytic series was noted.

PURPOSE: It's well known that the Epstein-Barr virus (EBV) is associated with endemic Burkitt's lymphoma and B cell lymphomas in immunocompromised individuals, and undifferentiated carcinoma of the nasopharynx. A clonotypic proliferation of EBV has been demonstrated in the neoplastic cells of these malignancies, suggesting a causative role of EBV in the tumorigenesis. More recently, it was identified that EBV has been linked to Hodgkin's disease and B or T-cell non-Hodgkin's lymphomas (NHLs) without preexisting immunodeficiency. MATERIAL AND METHOD: To determine the immunophenotype and incidence of EBV infection in sporadic NHLs of Korea, We investigated 90 cases of NHLs through immunohistochemistry and polymerase chain reaction, respectively. RESULTS: Sixty-nine of 90 (77%) of NHLs are of B-cell type, 18 of 90 (20%) of NHLs are of T-cell type and 3 out of 90 (3%) of NHLs are undefined lineage by immunohistochemistry. EBV genome was detected in 7 out of 69 (10%) B-cell lymphomas, 5 out of 18 (28%) T-cell lymphomas and 1 out of 3 (33%) non-B and non-T cell lymphomas by polymerase chain reaction. The male/female ratio of EBV-positive NHLs was 2.25:1. There are no prominent differences in age distribution and tumor localization between EBV- positive groups and negative groups. CONCLUSION: EBV positivity in T-cell NHLs is rather higher than in B-cell NHLs and this finding suggests that there is inter-relation association between EBV and T-cell NHLs, although the exact nature of this association remains to be established.

Metabolic encephalopathy is a critical condition that can be challenging to diagnose. Imaging provides early clues to confirm clinical suspicions and plays an important role in the diagnosis, assessment of the response to therapy, and prognosis prediction. Diffusion-weighted imaging is a sensitive technique used to evaluate metabolic encephalopathy at an early stage.Metabolic encephalopathies often involve the deep regions of the gray matter because they have high energy requirements and are susceptible to metabolic disturbances. Understanding the imaging patterns of various metabolic encephalopathies can help narrow the differential diagnosis and improve the prognosis of patients by initiating proper treatment regimen early.

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

The aberrant or ectopic thyroid in lateral neck is a rare developmental anomaly. Furthermore, the primary thyroid carcinoma arising in ectopic thyroid is extremely rare, only a few cases have been reported so far in English literature. We report a 64-year-old male with left transglottic cancer and primary papillary carcinoma from lateral aberrant thyroid in left lateral neck. Preoperatively, we diagnosed as transglottic cancer with ipsilateral neck metastasis. The patient underwent total laryngectomy, left selective neck dissection and left thyroidectomy. Finally, the patient was diagnosed as left transglottic cancer and papillary carcinoma from lateral aberrant thyroid. Surgeons should take into account a primary ectopic thyroid carcinoma arising in lateral neck may co-exist with another type of head and neck tumor.

There are relatively rare cases concerning about concurrent papillary thyroid cancer and thyroid tuberculosis with cervical tuberculous lymphadenitis in English literature so far. Cervical lymphadenitis (scrofula) is a common manifestation of extra-pulmonary invasion of the tuberculosis. A cervical tuberculous lymphadenitis could be confused with metastatic lymph node from the thyroid cancer. A 49-year-old woman with multiple right thyroid nodules of Bethesda category VI referred our department for surgery. We performed the right thyroid lobectomy with anterior compartment neck dissection. The histopathology revealed concurrent papillary thyroid carcinoma and thyroid tuberculosis with cervical tuberculous lymphadenitis. We report a unique case of concurrent papillary thyroid cancer and tuberculosis involving the thyroid gland and ipsilateral paratracheal lymph node with literature review. To our best knowledge, such case has not been reported earlier.

A 35-years-old man was hospitalized with gene-ralized edema. 6 months ago, the patient was operated by radical subtotal gastrectomy for advanced gastric adenocarcinoma. The patient presented with multiple liver metastasis and the massive proteinuria. The patients renal biopsy revealed minimal change nephrotic syndrome and treated with prednisolone and diuretics. The patient was improved clinical symptome and decreased 24 hours urine protein. In literature reviewed, gastric carcinoma was not associated with minimal change nephrotic syndrome. We experienced advanced gastric carcinoma associated with minimal change nephrotic syndrome, thus we report it.
