Endoscopic Removal of Remained Drawstring After Percutaneous Transhepatic Biliary Drainage / 고신대학교의과대학학술지

The percutaneous transhepatic biliary drainage (PTBD) is an effective intervention as a palliative therapy for relieving a jaundice and cholangitis. It may be used in place of Endoscopic retrograde cholangiopancreatography (ERCP) in the obstructive biliary disease. Recently, by developing invasive procedures, the incidence of the complications such as bleeding and perforation has been increasing in the diagnosis and treatment of hepatobiliary disease. We report here on a case of remained drawstring after PTBD in a 85-year-old man. The patient was conducted PTBD for relieving a jaundice and cholangitis. And then the patient had complained of abdominal pain constantly. A few days later, we removed PTBD and attempted ERCP for removal of CBD stone. The ERCP showed remained drawstring around ampulla of vater and we removed it by IT knife. The drawstring was successfully removed.

Extranodal Marginal Zone B-Cell Lymphoma of Mucosa-Associated Tissue Type Involving the Dura / Journal of the Korean Cancer Association, 대한암학회지

Primary central nervous system marginal zone B-cell lymphoma (MZBCL) is very rare, with only a few reported cases worldwide. It has an indolent disease course with high cure potential. We experienced a rare case of dural MZBCL of mucosa-associated lymphoid tissue (MALT) in a 69-year-old man who presented with headache. A magnetic resonance imaging scan of brain showed a 1.9×3.6-cm-sized extra-axial mass with a broad based dural attachment to the anterosuperior aspect of the falx cerebri, radiographically consistent with meningioma. Surgical resection yielded a MZBCL of the MALT type. Histopathology revealed a lymphoplasmacytic infiltration of the dura, and immunohistochemical study showed a B-cell phenotype with CD20, bcl-2, MUM-1, Ki-67 positive. He was treated with chemotherapy after complete surgical resection and remained free of disease at 30 months after chemotherapy. MALT lymphoma must be considered in the differential diagnosis in patients presenting radiographically with meningioma.

Spontaneously Regressed Immunoglobulin IgG4-related Lung Disease Presenting as Multiple Cavitary Nodules / 대한내과학회지

Immunoglobulin (Ig) G4-related disease was recently recognized as a systemic fibro-inflammatory disease characterized by dense lymphoplasmacytic infiltrates, storiform fibrosis, and obliterative phlebitis with IgG4-positive cells in the target tissues. This disease can localize to a single organ or be diffuse in multiple organs. Pulmonary manifestation in IgG4-related lung disease presents as various sized nodules, lung masses, patchy ground-glass opacities, consolidation, thickened bronchovascular bundles, nodular pleural lesions, and interstitial lung disease. Traditional treatment for IgG4-related lung disease includes systemic (cortico) steroids. Here, we report a case of IgG4-related lung disease presenting as multiple cavitary nodules that spontaneously regressed without systemic steroid use.

A First Case of Solid Pseudopapillary Tumor of the Pancreas in an Old Man in South Korea / 대한내과학회지

Solid pseudopapillary tumor (SPT) of the pancreas is a rare tumor that typically affects young women without causing significant clinical symptoms. No case of SPT in an old man has been reported in South Korea, and such cases are very rare worldwide. We report a 70-year-old man with SPT of the pancreas with multiple organ metastasis. Although surgical resection is the treatment of choice for SPT, we decided not to treat, considering his age and the disease severity.
