1.Combined Mucinous Tumor and Carcinoid of Appendix Associated with Mucinous Tumor of Ovary and Pseudomyxoma Peritonei: A case report .
Korean Journal of Pathology 1999;33(11):1094-1096
We report a case of mucinous cystadenoma of uncertain malignant potential and carcinoid of appendix associated with bilateral mucinous cystadenoma of ovary and pseudomyxoma peritonei. The patient was a 46-year-old female. She suffered from dyspnea and lower abdominal palpable masses for several months. Ultrasonogram showed multilocular huge ovarian cysts. Appendectomy, transabdominal hysterectomy, bilateral salphingo-oophorectomy and biopsy of omentum were performed. The bilateral ovaries measured 16 11 cm and 7X5 cm in size, respectively. The both ovaries showed multilocular cysts filled with thick mucus material. The ovarian cysts were covered by a single layer of columnar epithelium with focal proliferation. Mucus materials dissected through the ovarian stroma (pseudomyxoma ovarii). The tip of appendix was dilated and covered by mucus material. The cut surface showed a cyst and a yellowish solid mass proximal to the cyst. Microscopically, the appendiceal cyst was lined by stratified columnar epithelium with moderate cytologic atypia. Mucus material dissected through the wall. In the proximal portion of the appendix, a classic carcinoid with focal tubular form was present in submucosa and muscle layer. The omentum was covered by thick mucus material. Microscopically, the omentum showed mucinous epithelium and mucus material (pseudomyxoma peritonei).

PURPOSE: Misdiagnosed breast cancer on screening mammography was retrospectively reviewed in an attempt to analyze the cause for the undiscovery and to determine findings that might have been suggested on the mammographic examination. MATERIALS AND METHODS: Of the 173 breast cancers that were pathologically proven, 17 breast cancers misdiagnosed on mammogram was retrospectively analyzed for the causes of the misinterpretation and predominant secondary findings. RESULTS: Three of the 17 were negative on mammography except for dense breast. Two patients had localized asymmetricity without visible mass. Ten patients had benign-looking mass which was well-defined (n=5), partially defined(n=2), multiple (n=l), or included benign-looking calcifications(n=2). Remaining two cases were retrospectively diagnosed as misinterpreted breast cancers. Various secondary findings such as were useful in the diagnosis of breast cancer. CONCLUSION: Meticulous observation could improve the diagnostic yield of breast cancer in mammography.

BACKGROUND: Direct observation of healthcare workers is commonly used in hospitals to investigate hand hygiene compliance. However, the hand hygiene compliance rate may increase due to the Hawthorne effect, which is the modification of behavior simply because subjects become aware that they are being observed. The objective of this study was to investigate the occurrence of the Hawthorne effect when directly observing hand hygiene compliance in intensive care unit (ICU) healthcare personnel. METHODS: A total of 87 staff members from the coronary care unit and cardiac surgery ICU of a general hospital in Seoul were included in this study: 24 residents and interns, 55 nurses, and 8 nursing assistants. Both covert and overt observations, where subjects were either unaware or aware of any direct observation, were performed on separate occasions. RESULTS: A total of 1,052 covert and 1,336 overt observations were documented over 30 and 34 occasions, respectively. Overall hand hygiene compliance was significantly higher with overt observation than with covert observation (1,041/1,336, 77.9% vs. 659/1,052, 62.6%, P<0.001). The Hawthorne effect was present in all professions and behaviors, with the exception of nursing assistants, and prior to touching a patient. CONCLUSION: Direct observation of hand hygiene compliance was associated with the Hawthorne effect when observations were made overtly and this was likely to contribute to an overestimation of compliance rate.

Juvenile dermatomyositis is an uncommon autoimmune disease with classic heliotrope discoloration of eyelids, erythematous skin rash of joints and proximal muscle weakness. Quite different from adults, malignancy is rarely accompanied in juvenile dermatomyositis. However vasculitis, muscle atrophy, calcification and gastrointestinal involvement are often observed in juvenile dermatomyositis. A six year old boy was admitted with chief complaints of general weakness and skin rash. Muscle biopsy was performed which was consistent with dermatomyositis. The patient was treated with intravenous immunoglobulin, steroid, methotrexate and physiotherapy. We report a case of juvenile dermatomyositis.

PURPOSE: Laparoscopic approaches to the anterior abdominal wall are difficult because of the inherent limitations of laparoscopic surgery. METHODS: A 25-year-old young female visited to our hospital with an incidentally-found palpable abdominal mass. Computed tomography revealed a 7-cm round enhancing mass arising from the left posterior rectus sheath. The patient underwent laparoscopic excision of the inner mass arising from the anterior abdominal wall. RESULTS: The operation lasted for 45 minutes and there was no measurable bleeding during the procedure. Pathological assessment revealed that the tumor was a DTF 7.0 cm in size. The patient was discharged on the second postoperative day in good condition, and is currently being followed on a routine basis for surveillance without adjuvant therapy. CONCLUSION: Laparoscopic approach for the anterior abdominal wall tumor could be feasible in select patients. This minimally-invasive approach helps to ensure good cosmetic outcomes and quality of life.

Intraosseous lipoma is a very rare primary tumor of the bone. We report four cases of intraosseous lipoma. The patient ranged in age from 34 to 59-year-old (median age: 35 year-old). There were three men and one woman. All of four cases presented with pain. The involved bones were calcaneus in two cases, tibia in one case and ilium in one case, respectively. In all cases plain x-ray film revealed well-defined lytic lesion. Their size ranged 2 to 4.5 cm (mean size: 3.5 cm). Histologic examination showed mature adipose tissue. Three cases showed secondary changes such as atrophic bone, fat necrosis, fibrosis, dystrophic calcification, and reactive ischemic bone formation. The clinicopathologic and roentgenographic correlation are necessary in establishing correct diagnosis of this tumor.

The Korean Journal of Hepatology 2008;14(3):394-398
We report two cases of hepatocellular carcinoma with prominent lymphocytic infiltration, which has been described as a subtype of hepatocellular carcinoma with good prognosis. One case showed lymphoid follicles and dense lymphocytic infiltrates within the tumor and its periphery, and the other case showed marked lymphocytic infiltration in the cancerous tissue. Piecemeal necrosis of cancer cells and atypical reactive changes were evident. The two cases were seronegative for hepatitis B surface antigen, antibody to hepatitis C virus, and Epstein-Barr virus DNA. One of the cases showed Clonorchis infestation. The prognostic significance of lymphocytic stroma in hepatocellular carcinoma requires further investigation.
