A Case of Metastatic Adenocarcinoma of the Appendix from Stomach Adenocarcinoma / 대한소화기내시경학회지

Adenocarcinoma of the appendix is a rare neoplasm. Metastatic adenocarcinoma of the appendix from stomach adenocarcinoma is also a very rare finding. A 72-year-old man complained of right lower quadrant abdominal pain for 10 days, and he was diagnosed with acute appendicitis. Appendectomy was performed by a general surgeon. Adenocarcinoma was found on the postoperative biopsy. Subsequently, gastric adenocarcinoma was diagnosed on the gastroscopy with biopsy, and this was proven to be the original site of the appendiceal adenocarcinoma.

A Case of Splenic Pseudocyst Difficult to Differentiate from Splenic Lymphangioma / 대한소화기학회지

Splenic pseudocyst is a rare complication of abdominal trauma. Although it is rare, splenic pseudocyst is well-documented in the literature. According to the current classification, approximately 30% of all splenic cysts or pseudocysts result from direct abdominal trauma. In addition, chronic pancreatitis leads to change of nearby organs with possible acute and chronic complications including splenic lesions. This unusual complication can occur in both emergent and nonemergent conditions. The useful diagnostic procedures to assess intrasplenic pseudocyst are sonogram, CT scan, splenic scan, and occasionally angiography. However, definite diagnosis of pseudocyst is possible only after splenectomy when the absence of epithelial lining is confirmed histologically. Splenic pseudocyst requires surgical resection. We experienced a 31-year-old man who confirmed of warmness in the left side of back with left upper quadrant abdominal pain for several months. First impression was splenic lymphangioma based on CT scan and sonogram finding. Splenectomy was performed. Microscopic examination revealed splenic pseudocyst with fibrous capsule without epithelial lining.
