Warthin’s tumor is the most common monomorphic adenoma of parotid gland. It can be coexistent with other salivary gland tumors or metachronous, multifocal, unilateral, bilateral which perplexes diagnosis hence delaying over/under treating ailment. Rare cases are described in young population especially non-smoker females. We present a case arising left 20-year-old female.

Most cases of esophageal cancer and colorectal cancer in Taiwan are diagnosed in the advanced stage and treated by surgery or concurrent chemoirradiation. The detection rates of early esophageal cancer and early colorectal cancer are still low in Taiwan. Metachronous early esophageal cancer and early colorectal cancer have rarely been reported. Endoscopic mucosal resection (EMR) is a well-estab...

Primary adenocarcinoma of the upper urinary tract, particularly of the ureter, is an extremely rare entity. We are reporting on the first case of metachronous appearance in one patient. The 71-year-old man underwent partial ureterectomy (R0 resection) for primary adenocarcinoma of the left distal ureter. 3 years later, nephroureterectomy had to be performed because of metachronous primary adeno...

Serrated adenomas are the precursors of at least 5.8% of colorectal cancers; otherwise little is known of their clinical significance in comparison with conventional adenomas and hyperplastic polyps. We compared the risk of metachronous lesions in colorectal serrated adenomas, conventional adenomas, and hyperplastic polyps. A consecutive series of patients with colorectal polyps first diagnosed...

Lynch syndrome (LS) is a disorder caused by mismatch repair gene mutations, which have been recognized to be associated with an increased frequency of colorectal and extracolorectal tumors. However, it remains controversial as to whether total or segmental colectomy should be performed to treat colorectal cancer in patients with LS. A 58-year-old male underwent total colectomy with ileostomy fo...

Metachronous solitary metacarpal bone metastasis from rectal cancer has not been reported previously. Here, we describe a 54-year-old woman who underwent abdominoperineal resection for rectal cancer following neoadjuvant chemoradiotherapy. The resected specimen contained adenocarcinoma with no lymph node metastases (Stage II, T3N0M0); no adjuvant chemotherapy was administered. Fifteen months af...

The Authors report on a patient admitted several times for the occurrence of five multiple metachronous primary malignancies (laryngeal carcinoma, endometrial adenocarcinoma, rectal cancerous polyp, Vaterpapilla carcinoma and transverse colon cancer). All five carcinomas were independent primary cancers and the lenghty time intervals between the onsets of each individual tumours confirm their i...
