A singularly long-surviving (15 years) disease-free case of a stage II adenosquamous carcinoma of the larynx is described. A review of the literature reveals that prognosis of this aggressive malignant neoplasm is poor (mean 2-3 years free of disease) on account of local recurrences, early cervical lymph node metastasis and distant dissemination. This long survival rate emphasises the importanc...

Colorectal cancer is the third leading cause of death in Taiwan. Endoscopic resection treatment choice for stage I colorectal without risk lymph node metastases. Unfavorable histological features predict high-risk neoplasm; addition, surface change T1 under image-enhanced endoscopy also help recognition neoplasm. Through case presentation, we aim to demonstrate how discriminate from low-risk co...

Metastasis to the pituitary gland is an unusual situation in clinical practice, but the frequency thereof is increasing due to the increased survival of cancer patients, and greater availability of imaging. In most cases, they are found between the sixth and seventh decades of life, as determined in image examination of patients with known malignant neoplasm, but, generally, asymptomatic with r...

BACKGROUND The gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN) is the most common type of neuroendocrine neoplasm. We summarized data in our centre to investigate the clinicopathological features, diagnostic methods, therapeutic approaches and prognosis for this neoplasm to increase knowledge of this disease in Asian populations. METHOD A total of 122 patients treated at Sun Yet-san ...

With the exception of metastatic involvement of adenomas of endocrine glands, metastasis of one primary tumour to another independent neoplasm is a rare occurrence. This paper records two such examples.

Ovarian Burkitt’s lymphoma is rare in adulthood. Metastatic spread from ovarian malignancies occurs most commonly to the peritoneum, with nodular thickening of the peritoneum and serosal surface of the bowel, omental thickening (omental cake) and ascites. Metastasis to the para-aortic lymph nodes and liver has also been reported. Nonetheless, to the best of our knowledge, metastasis to the retr...

Granular cell tumor is a rare benign neoplasm most commonly appears in the head and neck region, especially in the tongue, cheek mucosa, and palate. Occurrence in limbs is even rarer. These tumors account for approximately 0.5% of all soft tissue tumors. Granular cell tumor can also affect other organs including skin, breast, and lungs. Local recurrence and metastasis is potentially higher in m...

Gastrointestinal stromal tumors (GISTs) are rare, but are the most common mesenchymal neoplasm of the gastrointestinal tract. The most common sites of metastasis are liver and peritoneum, while bone metastasis is rare. We report on a patient with skull metastasis after seven years of treatment with imatinib for metastatic GIST. She underwent metastasectomy consisting of craniectomy with excisio...

We report a rare case of clinically significant secondary prostatic neoplasm. In a patient with outflow obstruction, a transurethral resection of the prostate revealed a metastasis of a signet ring cell carcinoma of the stomach in the resected prostatic tissue.
