- BACKGROUND
Idiopathic duct centric pancreatitis (IDCP) is a subtype of autoimmune pancreatitis (AIP) that is histologically characterized by granulocytic epithelial lesion and scarce IgG4-positive cells. This subtype of AIP has not been documented in Asian countries.
METHODS
We reviewed 38 histologically confirmed AIP cases and classified them into lymphoplasmacytic sclerosing pancreatitis (LPSP) and IDCP. Then, clinicopathological characteristics were compared between LPSP and IDCP.
RESULTS
Fourteen cases (36.8%) were IDCP. IDCP affected younger patients more than LPSP. IDCP was associated with ulcerative colitis in 35.7% of cases, whereas LPSP was associated with IgG4-related sclerosing diseases such as cholangitis, retroperitoneal fibrosis or sialadenitis in 41.7% of cases. IDCP was microscopically characterized by neutrophilic ductoacinitis with occasional granulocytic epithelial lesions, whereas LPSP was characterized by storiform inflammatory cell-rich fibrosis and obliterative phlebitis. IgG4-positive cells were not detected in any IDCP case but more than 20 IgG4-positive cells per high-power-field were invariably detected in LPSP cases. All patients with IDCP responded dramatically to steroids without recurrence, whereas 33.3% of patients with LPSP developed recurrences.
CONCLUSIONS
IDCP is clinicopathologically distinct from LPSP and can be diagnosed when neutrophilic ductoacinitis or granulocytic epithelial lesions are observed in a pancreatic biopsy under the appropriate clinical setting.

Abstract
PDF
- Neuroblastoma is a malignant tumor of primordial neural crest origin. It usually develops along the sympathetic nervous system, such as the adrenal glands or paramedian sympathetic chain and metastasizes to the liver most frequently. However, a primary hepatic neuroblastoma has not been reported yet. Here, we report a case of 29-year-old woman who presented with a solitary hepatic mass. Grossly, the mass was large, creamy, rubbery firm, and showed focal hemorrhage and central cavitation. Microscopically, the tumor cells were arranged in small nests of spindle to ovoid cells with abundant neuropil. The neuroblastic nature of the tumor was confirmed by immunohistochemistry and electron microscopy. No extrahepatic mass was found, despite a thorough systemic survey such as chest and abdominopelvic computed tomography (CT) scans and a whole body positron emission tomography-CT study. To the best of our knowledge, this is the first report of a bona fide primary hepatic neuroblastoma.

Abstract
PDF
- Fibromatosis can occur at various sites, but intracranial fibromatosis is exceptionally rare. Here, we report a case of intracranial fibromatosis arising in the suprasellar area of a 52-year-old woman who had undergone a surgery at that site. A computed tomography scan revealed a heavily calcified, highly enhancing, poorly demarcated mass in the left sellar area that extended into the left suprasellar, parasellar areas, and orbital apex and completely encased the left distal inferior cerebral artery. Histologic and immunohistochemical features were compatible with those of fibromatosis, although the cellularity was focally higher than usual. The etiology of extra-abdominal fibromatosis is unknown, but physical injuries such as trauma and irradiation have been reported to be associated with its occurrence. Although fibromatosis is rare in the intracranial area, it should be considered as a differential diagnosis when an intracranial mass occurs at a previously injured site.

Abstract
PDF
- BACKGROUND
Surgical resection is the treatment of choice of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. However, the benefit of clearing resection margin is still controversial.
METHODS
We reviewed 281 surgically resected cases of IPMN.
The recurrences were compared according to the histologic grade (benign or borderline IPMN, malignant noninvasive IPMN, invasive carcinoma) and size (pancreatic intraepithelial neoplasia, PanIN, less than 0.5 cm in the long axis; and IPMN, greater than or equal to 0.5 cm) of the residual lesions at the resection margin.
RESULTS
Sixty cases (21.4%) were invasive carcinoma, and 221 (78.6%) noninvasive cases included 87 (31.0%) benign, 107 (38.1%) borderline and 11 (3.9%) malignant noninvasive IPMN cases. In noninvasive IPMN, increased recurrence in patients with five or more years of follow-up was only related to the involvement of resection margin by severe dysplasia. The recurrence of invasive carcinoma was high (27.3%) even when the resection margin was clear, and was not related to the grade or size of residual tumors at the resection margin.
CONCLUSIONS
Invasiveness is a strong risk factor for recurrence in IPMN regardless of the status of the resection margin. However, in noninvasive IPMN, histologic grading of residual lesions at the resection margin predicts local recurrence.
