Background: Breast cancer in developing countries is on the rise. There are currently no guidelines to screen women at risk in India. Since mammography in the western world is a well-accepted screening tool to prevent late presentation of breast cancer and improve mortality, it is intuitive to adopt mammography as a screening tool of choice. However, it is expensive and fraught with logistical issues in developing countries like India. Materials and Methods: Our breast cancer screening camp was done at a local district hospital in India after approval from the director and administrators. After initial training of local health care workers, a one-day camp was held. Clinical breast examination, mammograms, as well as diagnostic evaluation with ultrasound and fine needle aspiration biopsy were utilized. Results: Out of total 68 women screened only 2 women with previous history of breast cancer were diagnosed with breast cancer recurrence. None of the women in other groups were diagnosed with breast cancer despite suspicious lesions either on clinical exam, mammogram or ultrasound. Most suspicious lesions were fibroadenomas. The average cost of screening women who underwent mammography, ultrasound and fine needle aspiration was $30 dollars, whereas it was $16 in women who had simple clinical breast examination. Conclusions: Local camps act as catalysts for women to seek medical attention or discuss with local health care workers concerns of discovering new lumps or developing breast symptoms. Our camp did diagnose recurrence of breast cancer in two previously treated breast cancer patients, who were promptly referred to a regional cancer hospital. Further studies are needed in countries like India to identify the best screening tool to decrease the presentation of breast cancer in advanced stages and to reduce mortality.

Background: Some tumor types are related to HIV, including non-Hodgkin lymphoma (NHL). The morbidity and mortality of NHL has remained high, even after highly active antiretroviral therapy (HAART) was introduced. We collected cases of AIDS with NHL, and evaluated the imaging features and strategies for diagnosis. Materials and Methods: There were 27 patients with AIDS and tumors confirmed by pathology. There were 9 patients with Burkitt lymphoma, 16 with diffuse large B cell lymphomas (DLBCLs), and 2 with primary central nervous system (PCNS) lymphomas. All of the patients underwent a series of imaging studies. Three radiologists analyzed the images, and any disagreement was discussed until consensus was reached. Results: The radiologic manifestations of AIDS with NHL were mainly masses and lymphadenopathy, 3 patients having one mass and 12 two or more masses. 7 patients had lymphadenopathy in one site and 3patients had lymphadenopathy in two or more sites. Coarse mucosal folds, thickening of the gastrointestinal wall, and lumen narrowing were typical manifestations of NHL within the gastrointestinal tract. There were 4 patients with masses and 5 with lymphadenopathy inthe 9 with Burkitt lymphoma, and 11 patients with masses 5 with lymphadenopathy in the 16 with DLBCLs. Conclusion: NHL is a malignancy that usually occurs in patients with AIDS. Imaging is an important method by which to evaluate lesions, masses, and lymphadenopathy. Fine needle aspiration biopsy and stereotaxis biopsy are useful methods by which to diagnose NHL.

Among total 108 cases of biopsy-proven fibroadenomas of the breast which obtained from the files of the Asan Medical Center during one year period from October 1998 to September 1999, 23 cases cytologically diagnosed as high risk group were reviewed to retrieve the mis-loading factors. Initial cytologic diagnoses of 23 cases were proliferative breast lesion with atypia(high risk) on 21 cases(91.3%) and papillary neoplasm in 2 cases(8.7%). When we reanalysed 23 cases by Masood scoring system, they were classified as one non-proliferative breast lesion(4.3%), 16 proliferative breast lesions without atypia (69.6%), and 6 proilferative breast lesions with atypia(25.1%). None were subject to the category of carcinoma. Cytologic features loading to the overdiagnosis of high grade epithelial lesions were as follows; cellular dissociation without nuclear atypia, nuclear pleomorphism, anisonucleosis, and occasional macronucleoli without nuclear enlargement, lack of myxoid stroma, and few naked stromal cells. To avoid cytologic overdiagnosis of fibroadenoma, mild to moderate nuclear pieomorphism without nuclear enlargement and cellular dissociation without nuclear atypia should not be regarded as criteria of high risk group.

Primary non-Hodgkin's lymphoma of the lung is rare among extranodal lymphomas. The most common form is low grade B-cell type originated from the mucosa-associated lymphoid tissue (MALT) of the lung and primary peripheral T cell lymphoma of the lung is extremely rare. We recently experienced a case of fine needle aspiration cytology of primary peripheral T cell lymphoma of the lung in a 39-year-old male patient. The cytologic smears revealed some sheets of reactive epithelial cells, epithelioid histiocytes, and numerous polymorphous population of lymphoid cells composed of small and intermediate sized lymphoid cells and mature lymphocytes. Lymphoid cells were slightly larger than normal mature lymphocytes and showed significant irregularity of nuclear membrane. The internal nuclear structure was marked by chromatin clumping, clear parachromatin areas, and inconspicuous nucleoli. Histopathologically, atypical small lymphocytes infiltrated in the interstitium and alveolar sac. By the immunohistochemical study and molecular biologic study of gene rearrangement, the T cell clonality of atypical lymphoid cells was confirmed.

Background and Objectives: Recently the tenn 'papillary microcarcinoma' has been proposed to designate carcinoma of 10 mm or less in diameter. In some cases, cervical lymph node metastasis preceding the occurrence of the primary tumor may be the first and sole manifestation of the disease. The objective of this study is to assess the clinical features of cervical metastasis in papillary microcarcinoma of thyroid glands. Materials and Methods: 9 cases with papillary microcarcinoma with neck metastasis were analyzed retrospectively. 5 cases are men and 4 are women. All patients complained of painless, movable neck mass. The symptom had been present from 1 month to 36 months. We reviewed clinical history, imaging studies, the results of fine needle aspiration, the surgical method, the pathologic results. Results: In 9 cases, no abnormalities of the thyroid gland were shown by imaging studies and thyroid scan. 3 cases were diagnosed by fine needle aspiration cytology. the others were not. Total thyroidectomy and neck dissection were performed in 9 cases and then pathology reports showed 2 case of multiple, 2 case of contralateral single and 5 cases of unilateral single thyroid microcarcinoma. They have no recurrence during follow-up period. Conclusions: Cervical metastasis from papillary microcarcinoma is variable clinical manifestation. The diagnosis of cervical metastasis from papillary microcarcinoma should be considered in patient with neck mass. We recommend total thyroidectomy with neck dissection and postoperative radioactive iodine ablation therapy in neck metastasis from papillary thyroid microcarcinoma.

Fine Needle Aspiration Biopsy Cytology (FNABC), which is known as the most accurate and cost-effective method for diagnosis of the thyroid nodule, may still result in indeterminate cases that are cellular paucity and show minor nuclear atypia. However, most cases are associated with suspicion of papillary thyroid carcinoma (PTC). A B-type Raf kinase (BRAF) mutation was found in about half of PTCs which is currently helping us to differentiate malignancies from benign lesions. Cases studied included 46 histological, confirmed PTC cases. FNABC 102 cell paucity and 74 atypia benign cases were previously diagnosed as suspicious of PTC using cytologic examination. These cases were analyzed for BRAF mutation by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) with a new restriction enzyme. In this study, the sensitivity and specificity were calculated and, BRAF mutation was detected by means of a histological method in 23 of 46 cases of PTC and no mutation was found in 22 cases. However, one case was not detected. In using FNABC, BRAF mutation was detected in 6 of 102 cases in cell paucity and in 11 of 74 cases in the atypia. Two cases were not detected in the atypia. The sensitivity and specificity of PCR-RFLP in FNABC were 60% and 97.4% respectively. Assessment of Formalin Fixed Paraffin Embedding (FFPE) block demonstrated similarly a 51.1% positive and 48.9% negative in PTC. Evaluation of BRAF mutation revealed high specificity and low sensitivity in using FNABC method. This study suggests that BRAF mutation analysis should be useful for the clinical diagnosis of PTC in FNABC with cytological findings suspicious for PTC.

Background and Objectives: Medullary thyroid carcinoma(MTC) is a rare tumor derived from the parafollicular C cells of the thyroid gland accounting for 5-10% of all thyroid malignancies. In Korea, there has been a few case report of medullary thyroid carcinoma(MTC) but their clinical analysis were not exactly studied. So, we made clinical study of 10 patients diagnosed as medullary thyroid carcinoma. Materials and Methods: We reviewed clinical data of 10 patients who were diagnosed as medullary thyroid carcinoma(MTC) from April 1973 to August 1998 at National Medical Center. Results: The incidence of MTC was 2.3% of all thyroid cancer and their mean age were 44.2 years old. Preoperative thyroid scan showed cold nodule in all patients and thyroid function test(TFT) was within normal range. Of the 10 patents, only 4 patients had diagnosis of MTC in preoperative fine needle aspiration biopsy. All the patients underwent total thyroidectomy with central neck dissection. Two patients with cervical lymph node metastasis underwent total thyroidectomy, central neck dissection and modified neck dissection. Two patients (20%) showed recurrence at the site of neck, lung, mediastinum, bone and liver. Conclusion: Most MTC is sporadic form and have peak incidence in the fifth decade and female preponderance. Preoperative fine needle aspiration biopsy is considered to be a clinically useful diagnostic method, but its accuracy is not considered as much high as others. Total thyroidectomy with central neck dissection may be an useful surgical modality in treating medullary thyroid carcinoma.

Since the diagnosis of malignancy and benign of thyroid gland diseases is difficult only by using ultrasonogram opinions, the combination of fine needle aspiration (FNA) has been generalized trend for precise pathological diagnosis. Therefore, the current study aimed to know about its availability. The study subjected 500 patients who received the FNA along with the ultrasonogram screening for thyroid gland from October, 2007 to April, 2008. As the equipments for the study, Philips HDI-3500 and Philips UITRAMARKer-9 (UM-9) were used to conduct the comparative analysis of pathological results that were obtained through the inspection of ultrasonogram screening and through ultrasonogram guided FNA. Among the 464 patients who were found to be benign from the ultrasonogram screening inspection, II cases of the FNA diagnosis results judged to be malignancy, and 13 cases of the FNA diagnosis resulted to be benign among 36 patients who were diagnosed to be malignancy. The cases observed as solid from the opinions of ultrasonogram screening were often found to be malignancy, and most of the malignancy results were observed to show the hypoechoic pattern. Among the patients diagnosed with malignancy from the diagnosis of FNA, the 32 patients were found to have the papillary carcinoma, and the benign type was observed to be goiter and hyperplasia in 263 patients, which took up 52.6%. The ultrasonogram screening test that is performed for the purpose of diagnosing thyroid gland diseases, it is distinctively an useful inspection to diagnosis the presence, size and shape of nodules. However, the results of performing of FNA for those of nodules which were observed to be benign from the ultrasonogram were often came up with malignancy and there were cases that the nodules diagnosed with malignancy were diagnosed as benign from the FNA diagnosis.
