- BACKGROUND
Primary splenic vascular lesions include the tumor and the inflammatory condition. A primary splenic vascular tumor is rare but is the most common tumor of the benign primary splenic tumors.
METHODS
We describe the clinicopathological, radiological, and immunophenotypical findings of 40 cases of primary vascular lesions identified at our hospital from 1996 to 2009.
RESULTS
The patients included 18 men and 22 women, aged 12 to 74 years, with a mean of 43.3-years and median of 40-years. They comprised 14 hemangiomas (35%), 13 lymphangiomas (32.5%), three hamartomas (7.5%), three littoral cell angiomas (7.5%), three sclerosing angiomatoid nodular transformations (SANT, 7.5%) and four angiosarcomas (10%). The majority of the patients (65%) were asymptomatic.
Some of the patients (32.5%) complained of abdominal pain, and 2.5% of the patients presented with fever. Metastases were identified in 75% of the patients with an angiosarcoma at the initial work-up. One angiosarcoma patient died of the disease despite adjuvant chemoradiotherapy. The radiological findings for hamartoma, littoral cell angioma, and SANT were nonspecific. Microscopically, six types of vascular lesions showed classic morphological and immunophenotypical features of their type.
CONCLUSIONS
One should be aware of rare splenic vascular lesions when radiological findings are nonspecific.
Histomorphological and immunophenotypical features are helpful for the differential diagnosis.

Abstract

- BACKGROUND
Since many patients with intestinal endometriosis present with gastrointestinal symptoms without a history of endometriosis, endoscopic examination of the intestinal tract is initially performed, often leading to a misdiagnosis.
METHODS
We reviewed the clinicopathologic findings of 18 samples from 15 patients with intestinal endometriosis who underwent endoscopic biopsy and/or surgical resection to identify diagnostically helpful findings.
RESULTS
All 7 biopsy specimens displayed relatively well-defined submucosal lesions, with non-mucinous glands lined by ciliated epithelium and surrounding cellular stroma containing spiral arteriole-like blood vessels. The stroma was immunopositive for CD10 in all cases. All but one specimen exhibited immunopositivity for ER and PR in both glandular and stromal components. In contrast to the overlying normal colonic mucosa, glandular epithelium with endometriosis was immunopositive for cytokeratin (CK) 7, but immunonegative for CK20 in all cases. Three cases were associated with adenocarcinoma in the same or different segments; specifically, two primary rectal adenocarcinomas and one endometrioid adenocarcinoma arising from endometriosis.
CONCLUSIONS
The characteristic features of endometrial glands and stroma, including non-mucinous glands without goblet cells, ciliated columnar epithelium, and cellular stroma with spiral arterioles, facilitate the accurate diagnosis of intestinal endometriosis, which can be confirmed by immunohistochemical staining.

Abstract
PDF
- 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.
