Apocrine carcinoma is a rare type of mammary cancer, which shows partial or total apocrine differentiation in either ductal or lobular carcinoma. The malignant transformation of apocrine epithelium of the breast was first described by Krompecher in 1916. It is well known that their relationship to true apocrine glands of the skin is only a morphological similarity, and this histological difference does not affect the prognosis. The authors experienced two cases of apocrine carcinoma of the breast which involved infiltrating ductal carcinoma of a 64-year old woman and intraductal carcinoma of a 69-year old woman respectively. Electron microscopic examination and brief review of literature was done.

Immunohistochemical analysis of 24 paraffin-embedded osteosarcomas was studied to evaluate the expression of simple cytokeratin, basal cytokeratin and epithelial membrane antigen(EMA) according to the histologic subtypes and anatomical locations. Mean age of the patients was 18 years. Anatomical locations of the tumors were femur(8), tibia(10), humerus(4), lumbar spine(1), and zygomatic arch(1). Histologic subtypes included osteoblastic(14), fibroblastic(4), chondroblastic(4), epithelioid(1), and mixed osteoblastic and fibroblastic(1). All were positive in the immunohistochemical stain for vimentin. The expression of cytokeratin and/or EMA was found in 10 cases(41.7%) regardless of anatomical locations and histologic subtypes. Positive immunoreaction for EMA was demonstrated in osteoblastic(5), chondroblastic(2), epithelioid(1), and mixed osteoblastic and fibroblastic(1) types. Osteoblastic (2), chondroblastic(2), and epithelioid(1) types among them also showed immunoreactivity with anti-simple cytokeratin monoclonal antibody, NCL-5D3. The expression of basal cytokeratin (NCL-LL002) was found in two osteoblastic, one chondroblastic, one epithelioid, and one mixed osteoblastic and fibroblastic types. These findings indicate that cytokeratin and EMA immunoreactivity can not be regarded as an absolute specific marker of the epithelial origin of tumor and may also occur in osteosarcoma.

BACKGROUND: Urography(IVU) is considered the best first investigation in patient with suspected urinary calculi, but recently ultrasonography(USG), combined with a plain film of the abdomen, has been suggested as an alternative. METHODS: We undertaken study to see if this approch can be used in emergency patients and outpatients by radiologists with different amounts of ultrasound experence. Some 192 patients with suspected urinary colic presenting to Koo Hospital Emergency Department and Youngnam Universith Hospital outward Department(IM, URO, FM) over 12-month period were studied. They had a plain abdominal film(KUB) and USG examination of the kidney, ureter, bladder following hydration and subsequently underwent IVU. Of these, 22 patients passed a stone before their IVU. The data analysis was performed on the remaining 170 patients. Urography was used as the gold standard. RESULTS: Some 170 patients subsequently underwent IVU at a mean interval of 1.8 days after the ultrasound examination. In 91 of 170 patients the IVU was positive. In 97 of 170 patients the combination of JUB plus USG was positive, leaving three false negative KUB plus USG. Thus the sensitivity of KUB plus USG was 97%, specificity was 89%, positive predictive value was 91%, and negative predictive value was 96%. CONCLUSIONS: Our findings in this study suggest that in the hydrated patient the combination of KUB plus US is a very sensitive and relative specific screening test. Because of the high negative predictive value of KUB plus US, urography is not likely to be helpful when KUB plus US are negative. Urography is indicated only if KUB plus US findings are equivocal or if intervention is necessa.ry.

Teratomas of the fallopian tube are extremely rare, and only about 50 cases have reported in the world literature. Most cases of mature cystic tubal teratoma are asymptomatic and are discovered as an incidental finding on physical or radiologic examination, or at the time of laparatomy. We report a case of mature cystic teratoma of the right fallopian tube which was discovered during pelvic ultrasonogram for antenatal care in a 28 year old woman. Right salpingectomy was performed during cesarean section for cephalo-pelvic distortion at IUP 39 weeks. Gross examination of the right fallopian tube reveals a distended fallopian tube, measuring 8cm in length and 2cm in diameter. On section, it is filled with several small pedunculated nodules and cysts containing sebaceous materials. Microscopically the tumor was seen in continuity with the lining epithelium of mucosal folds. The majority of the tumor was composed of well differentiated mature elements of three germ layers with skin and skin appendages, mature brain tissue, bone, breast tissue, intestinal mucosa and bronchial epithelium.

Choriocarcinoma associated with a normal pregnancy is rare. Futhermore, choriocarcinoma coexistent with a viable pregnancy is even rarer and associated with a greater risk of hepatic and cerebral involvement. So timely diagnosis of the disease is important for successful treatment and aggressive diagnostic procedures may therefore warranted. The patient should be treated with primary intensive combination chemotherapy(EMA-CO) and the selective use of irradiation and surgical therapy. We experienced a case of metastatic choriocarcinoma of lung and kidney following preterm delivery at 34th week of pregnancy and so present it with brief review of literature.

The cecal perforation is very rare in pediatrics. Our center has experienced a 7-year-old girl with idiopathic perforated cecitis. The surgeon couldn't differentiate perforated cecitis from perforated appendicitis because of anatomical location, incidence and ambiguous radiologic result when this patient was admitted to our clinic due to RLQ pain.

OBJECTIVE: To analyze the tubal patency in the young-aged women underwent diagnostic laparoscopy with Fitz-High-Curtis Syndrome (FHCS). METHODS: Clinicopathologic results of young-aged women who underwent diagnostic laparoscopy with pelvic inflammatory disease from March 2005 through April 2007 were reviewed. Twenty six patients aged 19-29 years old and preserved their both tubes after diagnostic laparoscopy were included in this study. All were underwent chromopertubation test (CPT) during laparoscopy and postoperative hysterosalpingography (HSG) 3 months later. RESULTS: Of 26 patients, eight patients were diagnosed with FHCS and the others were not. There was no significant difference in mean age, mean hospitalization days, and frequency in past-history of parturition, abortion, chlamydia and gonococci infection between patients with FHCS and with non-FHCS (P>0.05). There was no significant difference in frequency of tubal obstruction in laparoscopic CPT (P>0.05) but not in postoperative outpatient HSG (P<0.05). CONCLUSION: The tubal obstruction may be more frequent in FHCS than non-FHCS and the reliability of laparoscopic CPT for diagnosing the tubal obstruction is supposed to be low. Therefore, as for FHCS patients, HSG should be executed to investigate tubal factor which is helpful to forecast the fertility.

PURPOSE: We evaluated the long-term outcome of the Gittes procedure for treatment of stress urinary incontinence. MATERIALS AND METHODS: A total of 84 women had Gittes bladder neck suspension carried out for the treatment of anatomic stress urinary incontinence. Long term (mean 51.4 months) results were evaluated using a questionnaire. RESULTS: Of the 58 patients assessed, 25 (43.1%) reported cure of stress urinary incontinence, 19 (32.8%) reported improvement, 12 (20.7%) were the same and 2 (3.4%) were worse after Gittes bladder neck suspension. Thirty-seven (63.8%) replied 'satisfactory' for the Gittes bladder neck suspension. Overall success rate was estimated as 62.1%. Depending on follow-up periods success rate was declined with time and by 5 years the success rate was 67.2%. CONCLUSIONS: Although the Gittes procedure was quick and easy to perform and was well tolerated with minimal complications, long term follow-up study of Gittes bladder neck suspension showed a declining success rate with time. Therefore it may not be a satisfactory procedure for the management of anatomic stress urinary incontinece in women.
