Progressive transformation of germinal centers (PTGC) is a rarely diagnosed, benign disease of the lymph nodes that commonly manifests as chronic lymphadenopathy. PTGC may be characterized by single or multiple non-tender lymph nodes, and it commonly involves the cervical, axillary, and inguinal areas. Although PTGC is identified with concurrent lymphoma in some patients, it is not considered as a premalignant entity. Histopathologic diagnosis of PTGC is rarely made, and imaging findings have been reported in very few studies. We present a case of PTGC that occurred at the contralateral axillary lymph nodes and mimicked metastatic lymphadenopathy after breast cancer surgery. We also discuss its imaging findings.

Gynecomastia is a benign enlargement of the male breast attributable to proliferation of the ductal elements. Gynecomastia has been rarely reported as an adverse effect of isoniazid therapy. We report the case of a 35-year-old man who was prescribed with isoniazid, rifampicin, ethambutol and pyrazinamide to treat pulmonary and lymphatic tuberculosis. After five months of treatment, the patient complained of painful engorgement in the bilateral breasts and the presence of male gynecomastia was confirmed with a physical examination and radiographical methods. The serum level of estradiol was also increased. Common causes of male gynecomastia were excluded through history taking and the laboratory findings. The anti-TB drugs were changed to a second line regimen due to radiographical progression and the intolerance of the patient to gynecomastia. Gynecomastia was relieved very slowly and a tender subareolar palpable mass decreased in size and consistency over five-month period after stopping the probable causative drug, isoniazid. From a review of the literature, gynecomastia has been shown to be a side effect of treatment with first line anti-tuberculosis drugs, and especially with isoniazid. We report the rare case.

The appearance of a tumor in the chest wall is rare compared to that in any other part of the body. It can be classified into benign and malignant types and can be located in the rib, clavicle, sternum, cartilage and soft tissues. Tumors that are metastatic are commonly located in the lung, breast, bone and pleura. But, the soft tissue mass of anterior chest wall is rarely metastasized from a distant organ that is not confined to the thoracic cavity. This and thus has rarely been described. A 68-year-old man was admitted to our hospital with a chief complaint of resting dyspnea. A huge non-tender mass of about $10{\times}15$ cm in size was visible on his left lower anterior chest wall. We pathologically confirmed that the mass was a metastatic renal cell carcinoma of clear cell type by incision biopsy. Through an incision biopsy, the mass was pathologically confirmed as a metastatic renal cell carcinoma of the clear cell type.

Purpose: The aim of this study was to investigate the diagnostic role of $^{99m}Tc$-Tetrofosmin in detection of breast cancer and compared with that of $^{99m}Tc$-MIBI. Material and Methods: Forty-eight patients with a clinically palpable mass or abnormal mammographic or ultrasonographic findings had $^{99m}Tc-MIBI\;and\;^{99m}Tc$-Tetrofosmin scintimammographies after intravenous injection of 925 MBq of radiopharmaceuticals. The scintimammographs were correlated with histopathologic findings. Results: Thirty-three patients were diagnosed with breast cancer and 15 patients with benign breast diseases. The numbers of true positive, true negative, false positive, and false negative cases of $^{99m}Tc$-MIBI scintimammography were 29, 10, 5, and 4 respectively. The sensitivity, specificity, positive predictive value, and negative predictive value of $^{99m}Tc$-MIBI scintimammographies were 87.8%, 66.7%, 85.3%, and 71.4% respectively. The numbers of true positive, true negative, false positive, and false negative cases of $^{99m}Tc$-Tetrofosmin were 31,10, 5, and 2 respectively. The sensitivity, specificity, positive predictive value, negative predictive value of $^{99m}Tc$-Tetrofosmin were 93.9%, 66.7%, 86.1%, and 73.3% respectively. One patient was false negative in both $^{99m}Tc-MIBI\;and\;^{99m}Tc$-Tetrofosmin acintimammographies and its size was 0.5 cm. Conclusion: $^{99m}Tc-Tetrofosmin\;and\;^{99m}Tc-MIBI$ were non-invasive and useful in detection of breast cancer and $^{99m}Tc$-Tetrofosmin was comparable to the $^{99m}Tc$-MIBI in detection of primary breast cancer.

Background : In recent years, numerous human tumor specific antigens such as melanoma antigen gene(MAGE) that is recognized by autologous cytotoxic T lymphocytes have been identified. MAGE is expressed in many human malignancies in various organs, such as lung, breast, stomach, esophagus and leukemia. Therefore MAGE has been studied widely for tumor diagnosis and immunotherapy. But, so far there were no clinical studies evaluating the role of MAGE in pleural effusion. We investigated the expression of MAGE in the patients with exudative pleural effusion for it's diagnostic utility and the results were compared with those of cytologic examinations. Methods : Diagnostic thoracentesis was performed in 44 consecutive patients with exudative pleural effusion during 6 months. We examined the expression of MAGE and cytology with the obtained pleural effusion. Expression of MAGE was interpreted by means of a commercial kit using RT-PCR method. Enrolled patients were divided into two groups such as malignant and benign and we analyzed its' sensitivity and specificity. Results : There were no significant differences between two groups in age, sex, white blood cell counts in pleural fluid, pleural fluid/serum protein ratio and pleural fluid/serum LDH ratio. The sensitivity and specificity of MAGE were 72.2% and 96.2% respectively and the positive predictive value and negative predictive value of MAGE were also 92.9% and 83.3% respectively. The sensitivity and negative predictive value of cytologic examinations were 66.7% and 81.3% respectively. There were no significant differences between sensitivities of MAGE and cytologic examinations but false positive result of MAGE was found in 1 case of tuberculous pleurisy. Conclusion : MAGE is a sensitive and specific marker for the differential diagnosis between benign and malignant effusion in patients with exudative pleural effusion. And MAGE would provide the equal sensitivity compared with that of cytologic examination in patients with malignant pleural effusion if 5mL of the pleural fluid is examined.

Purpose: Dietary protein induced proctocolitis (DPIPC) can be considered as a cause of rectal bleeding or blood streaked stool in otherwise healthy-looking infants in the first several months of life. Failure to appreciate this entity may lead to inappropriate diagnostic or therapeutic intervention. This study aimed to ascertain the clinical features, treatment and prognosis of DPIPC. Methods: We reviewed 13 infants retrospectively, presented with bloody stool in early infancy. They were diagnosed as DPIPC clinically in Pusan National University Hospital from May 2002 to June 2004. Results: Seven males and six females were included. The mean age at onset of bleeding was $96.8{\pm}58.8days$. The mean frequency of hematochezia was $2.6{\pm}2.5$ times a day. Duration from onset of symptom to diagnosis was $35.5{\pm}55.0days$ and duration from onset of symptom to resolution of bleeding was $58.7{\pm}67.0days$. Nine (69.2%) were exclusively breast-fed infants and two (15.4%) were formula-fed infants. All but one infant did not have family history of other allergic diseases. A dietary history of ingestion of cow's milk, nut or shellfish was present in three mothers. Peripheral eosinophil count was normal to slightly elevated (total WBC count $10,555{\pm}3,145/mm^3$, relative eosinophil count $6.3{\pm}3.0%$, absolute eosinophil count $659.0{\pm}532.2/mm^3$). Sigmoidoscopy revealed lymphonodular hyperplasia with surrounding hemorrhagic spots in the rectosigmoid colon in 6 infants. Histopathologic finding of colonic biopsies in 5 infants showed chronic inflammation with lymphoid follicular hyperplasia (5 infants), crypt abscess (3 infants), or mild infiltration of eosinophils (less than 20/high power field) in the lamina propria. Spontaneous resolution of rectal bleeding occurred in all infants without dietary change or medicine. Conclusion: Most infants with DPIPC experience a very benign course and have spontaneous resolution of rectal bleeding without changes in the mother's diet. In the case of strong evidence for DPIPC we suggest deferring further invasive investigation and continuing breast feeding.
