Carcinosarcoma of the stomach is a rarely occurring malignant biphasic tumor that consists of both carcinomatous and sarcomatous components simultaneously in a single tumor. The common carcinoma component is tubular or papillary adenocarcinoma and the mesenchymal sarcomatous components are variable and these include leiomyosarcoma, rhabdomyosarcoma, osteosarcoma and chondrosarcoma. However, neuroendocrine carcinomatous differentiation in the carcinomatous component is extremely rare. We present here a rare gastric carcinosarcoma that demonstrated neuroendocrine carcinomatous and leiomyosarcomatous differentiation in a 47-year-old man.

Castleman's disease is a rare benign lymphoproliferative disorder that frequently affects lymph nodes of the mediastinal thorax and the neck. It very rarely affects the renal sinus. We report a case of Castleman's disease arising in the renal sinus in a 64-year-old man. The patient visited the hospital with the chief complaint of hematuria. Abdominal computed tomography revealed a homogeneous mass in the sinus of the left kidney, radiologically interpreted as a malignant urothelial tumor. Subsequently, nephroureterectomy was performed, after which microscopic examination of the specimen revealed a diffuse lymphoproliferative lesion with reactive lymphoid follicles of various sizes and prominent plasma cell infiltration of interfollicular spaces, highlighted by immunohistochemical staining for CD138. The lesion was diagnosed as Castleman's disease of the plasma cell type. Although preoperative diagnosis of Castleman's disease is difficult and the incidence is exceedingly rare, it should be considered in the differential diagnosis of renal sinus tumors.

Carcinosarcoma of the salivary glands is a rare malignant tumor showing both malignant epithelial and mesenchymal components. Herein, we present a carcinosarcoma of the parotid gland in a 67-year-old man consisting of osteosarcoma and adenocarcinoma components with fine needle aspiration cytological findings. The tumor was composed predominantly of osteosarcoma and small areas of adenocarcinomatous components and a hyalinized nodule reminiscent of pleomorphic adenoma. The tumor showed infiltrative growth features with perineural, lymphatic, and vascular invasion. Despite postoperative adjuvant radiation therapy, multiple metastatic lesions occurred in the both lungs 5 months after surgery. As salivary gland carcinosarcoma has been known to demonstrate highly aggressive behavior, an accurate pathological diagnosis is prerequisite for appropriate treatment.

BACKGROUND: The diseases that cause neonatal cholestasis display several overlapping clinical feature. Making the differential diagnosis using liver biopsy specimens from infants with neonatal cholestasis is important for delivering the proper treatment. METHODS: We assessed the clinical manifestations, laboratory data, and histopathologic features of the pretreatment liver biopsy specimens from patients suffering with biliary atresia (n=66), intrahepatic bile duct paucity (n=15), and neonatal hepatitis (n=21). RESULTS: The gender distribution was nearly equal for the patients with biliary atresia and intrahepatic bile duct paucity, whereas males predominated for the cases of neonatal hepatitis. Only the gamma-glutamyl transferase level differed significantly amongst the groups. The diagnostic features for making the differential diagnosis of bile duct lesions included marked bile ductular proliferation, severe fibrosis, and bile duct loss. The difference of the average percentage of portal tracts with bile duct loss was statistically significant between the patients with intrahepatic bile duct paucity (73.9%) and those patients with neonatal hepatitis (39.1%) (p<0.001). CONCLUSIONS: Bile ductular proliferation, bile duct loss, and advanced fibrosis are useful for the differential diagnosis of neonatal cholestasis. Moreover, stricter diagnostic criteria for bile duct loss (more than 2/3 of bile ducts) should be applied for the definitive diagnosis of intrahepatic bile duct paucity, because bile duct loss also frequently occurs in infants suffering with neonatal hepatitis.

PURPOSE: Glucose uptake and glycolytic metabolism are enhanced in cancer cells, and increased expression of glucose transporter 1 (GLUT1) has also been reported. The aim of this study was to investigate GLUT1 expression in human breast tissues and invasive ductal carcinomas. METHODS: We used tissue microarrays consisting of normal breast tissue, ductal hyperplasia, ductal carcinoma in situ, invasive ductal carcinoma, and lymph node metastases. We examined GLUT1 expression in the microarrays by immunohistochemistry, reviewed the medical records and performed a clinicopathological analysis. RESULTS: Membranous GLUT1 expression was observed in normal and tumor cells. GLUT1 expression was higher in ductal carcinoma in situ, invasive ductal carcinoma, and lymph node metastasis than in normal tissue and ductal hyperplasia (p=0.002). Of 276 invasive ductal carcinomas, 106 (38.4%) showed GLUT1 expression. GLUT1 expression was correlated with higher histologic grade (p<0.001), larger tumor size (p=0.025), absence of estrogen receptor (p<0.001), absence of progesterone receptor (p<0.001), and triple-negative phenotype (p<0.001). In univariate survival analysis, patients with GLUT1 expression had poorer overall survival and disease-free survival (p=0.017 and p=0.021, respectively, log-rank test). In multivariate survival analysis with the Cox proportional hazards model, GLUT1 expression was an independent prognostic factor of poorer overall survival and disease-free survival (p=0.017 and p=0.019, respectively). CONCLUSION: GLUT1 expression seems to play an important role in malignant transformation, and the glycolytic phenotype in invasive ductal carcinoma may indicate aggressive biological behavior and a worse prognosis.

Cystic lymphangioma is also known as cystic hygroma, and this is a congenital malformation of the lymphatic system. Most lymphangiomas are present at birth and they are diagnosed by the age of 2. They are mostly located in the neck or axillary region. The breast as a site of origin is an extremely unusual location, and especially in adults. We report here on a case of cystic lymphangioma in a 36-year-old woman. Physical examination revealed a tender cystic mass in the upper outer quadrant of the right breast. Ultrasonography revealed an irregular hypoechoic mass lesion that was associated with irregular duct dilatation and several enlarged axillary lymph nodes. After the operation, the mass was revealed to be a cystic lymphangioma. Although it is very rare, cystic lymphangioma should be considered in the differential diagnosis of a breast mass in adults.

PURPOSE: To determine the intranasal causes of failed dacryocystorhinostomy (DCR) and the effects of transcanalicular diode laser-assisted revision surgery. METHODS: Twenty-four patients (29 eyes) who underwent revision surgery for a failed DCR at the Department of Ophthalmology, Ansan Hospital, Korea University between March 2009 and February 2011 were included in the present retrospective study. The intranasal causes of failed DCR, the time of symptoms such as epiphora and discharge after DCR, success rates of revision surgeries and follow-up periods were evaluated. RESULTS: Membranous obstruction was found in 25 eyes (86.2%) and was accompanied with granuloma in 10 eyes; these were the most common causes of failed DCR. The mean time for symptom development after DCR was 14.6 months, the success rate of the first revision surgery was 82.1% and good results were obtained in 5 eyes after the second revision surgery. Recurrence developed in 2 eyes, but symptoms improved after the lateral tarsal strip procedure. CONCLUSIONS: Membranous obstruction was the most common intranasal cause of failed DCR and transcanalicular diode laser-assisted revision surgery produced good results. Additionally, in patients with persistent epiphora following anatomically-patent revisional surgery, lacrimal pump failure due to lower eyelid laxity should be considered and corrected.
