Abstract Parotid gland is a rare site of metastasis from gastrointestinal (GI) tract primary cancer. Here, we present an interesting case report parotid unknown with probable lower GI as cancer, normal colonoscopy and upper endoscopy. This highlights the importance immunohistochemistry in taking treatment decisions during dilemmatic situations.

sialography is the retrograde injection of an iodinated contrast agent into the ductal system of salivary glands and this technique is the only method capable of adequately demonstrating the status of the ductal system. one of the indications of sialography is classification of the salivary ductal system fistulae. this classification has important prognostic and therapeutic values. in the prese...

Oncocytic carcinoma of the parotid gland is a rare neoplasm. To date 70 cases have been described in 55 reports. To the best of our knowledge the simultaneous occurrence of oncocytic carcinoma and second malignancy in another site (outside the parotid gland) has not been reported. An oncocytic carcinoma of the parotid gland is described in 56-year-old male with simultaneous breast cancer, empha...

BACKGROUND: Parotid gland metastasis in breast cancer is extremely rare, and only 14 cases have been reported between 1982 and 2010. CASE REPORT: A 67-year-old female patient was diagnosed with invasive lobular carcinoma of the left breast. Although clinical staging was T1N3M1 (stage IV), the tumor experienced a complete response to chemotherapy. We therefore performed a mastectomy followed by...

parotid stafne bone defect is a very rare and infrequent variant, which is located on the buccal or lingual surface of the mandibular ascending ramus. in this paper, a case of parotid stafne defect, which was incidentally discovered during dental radiographic examination, is reported. this bone defect was observed as a lucent oval-shaped defect on the lingual aspect of the right mandibular ramu...

Xerostomia (dry mouth), resulting from radiation damage to the parotid glands, is one of the most common and distressing side effects of head-and-neck cancer radiotherapy. Recent MRI studies have demonstrated that the volume reduction of parotid glands is an important indicator for radiation damage and xerostomia. In the clinic, parotid-volume evaluation is exclusively based on physicians' manu...

Parotid gland and cerebellum metastasis in lung cancer are extremely rare; very few cases have been reported. Here we present a case of a 56-year-old Chinese female patient who presented with a swelling in the right parotid gland. We diagnosed metastatic squamous-cell carcinoma from advanced lung cancer. The patient received 1 cycle nimustine (100 mg/m2 IV Day 1) and nedaplatin (80 mg/m2 IV Day...
