adenoid cystic carcinoma (adcc) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). about 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). three clinically obvious characteristics of adcc include slow growth rate, perineural invasion and high incidence of distant metastasis (1). the most commonly-affected sites of...

introduction: breast cancer is the second most common cause of brain metastasis. although patient prognosis is poor, isolated brain metastasis occasionally can be an option for treatment with curative intent in breast cancer patients. case presentation: we report a patient with invasive ductal carcinoma of the breast who developed an isolated right frontal lobe metastasis within 5 months of fin...

introduction : pulmonary adenosquamous carcinoma is an uncommon histological variety of bronchogenic carcinoma, and has histologic areas differentiated as both squamous cell carcinoma and adenocarcinoma and has clinical behavior more like that of adenocarcinoma. tumor stage is higher at the time of diagnosis, and survival is poorer. case presentation : we present a 65 years old woman with bulgi...

the paranasal sinuses are known to be a rare location for metastasis. renal cell carcinoma (rcc) is the most frequent primary tumor to metastasize to the sinonasal region, followed by lung and breast cancer. in particular, clear cell type rcc, which represents approximately 85% of rccs, is characterized by early metastasis, and it sometimes spreads to unusual sites (1, 2). metastatic tumors in ...

Although thyroid carcinoma is a relatively common form of malignancy, metastatic spread to the skull is rare. Here, we report a case of papillary thyroid carcinoma with frontal and parietal metastasis. A 61-year-old Chinese woman presented with a one year history of a growing mass on the center of the frontal and parietal bone, initially thought to be meningioma. Biopsy of the skull base mass a...

Sir, Opsoclonus-myoclonus syndrome (OMS) is a rare but distinctive disorder, characterized by irregular, continual, and conjugated chaotic saccades of the eyes accompanied by appendicular myoclonus and truncal ataxia. No etiological factor can be found in 50% of adult cases. In 20% of cases it may be paraneoplastic and may also be a manifestation of brainstem stroke or infection. The most commo...

We report the case of a woman with intracranial metastasis from an esophageal gastrointestinal stromal tumor (GIST) with the mutation site in the 3' end of exon 11. Frontal craniotomy was performed with complete resection of the mass, followed by postoperative stereotaxic radiotherapy (SRT). Intracranial metastasis from GISTs is extremely rare; we found only seven case reports in the literature.
