A Case of Appendicular and Rectal Metastasis from Gastric Cancer Detected by Endoscopic Resection / 대한소화기내시경학회지

A hematogenous or lymphogenous metastasis and a direct or disseminated invasion can occur in cases of a gastrointestinal metastasis. Moreover, a hepatic or peritoneal metastasis is common in advanced gastric cancer. However, a colonic metastasis, particularly an appendicular metastasis, is quite rare. Recently, we experienced a case with an appendicular submucosal tumor-like elevated lesion and multiple rectal elevated lesions during a colonoscopy in an advanced gastric cancer patient. The appendicular lesion was resected endoscopically and a biopsy of the rectal lesions was performed. The pathologic diagnosis was an appendicular and rectal metastasis of a signet ring cell carcinoma. We describe a case of appendicular and rectal metastasis from gastric cancer. The results highlight the importance of considering a metastatic carcinoma when an appendicular or rectal mass is found incidentally in a malignant neoplasm patient.

A Case of Multiple Verruciform Xanthoma of Oral Cavity and Gastrointestinal tract / 대한피부과학회지

Verruciform Xanthoma(VX) is a rare disease of unknown etiology that is typically solitary and predominantly located within the oral cavity. It is usually not associated with other lesions or metabolic abnormalities. Histologic features include acanthosis with uniform elongation of the rete ridges and xanthomatous cells that lie in are and typically confined to the papillary dermis. We report a rare case of multiple verruciform xanthoma that occurs in oral cavity and gastrointestinal tract simultaneously.
