Four poorly differentiated malignant lesions occurred in a 60-year-old Chinese male in the nasal cavity, submandibular gland, a lymph node in the neck, and the mandible. These malignant lesions developed within an 8-year period and each showed distinctive histological features. Among these malignant lesions, the neoplasm in the submandibular gland presented variegated histological and immunohis...

Ectopic thyroid gland is rarely seen in the submandibular region, thereby posing difficult diagnostic and management problems. Two Caucasian women presented with painful swelling in the submandibular region, which increased in size considerably during the preceding months. Ultrasound-guided fine needle biopsy (Ug-FNB) revealed ectopic thyroid tissue. In conclusion, ectopic thyroid gland with or...

Plexiform neurofibroma is more commonly seen in the orbit, neck, back, and inguinal region. It is extremely rare in the submandibular gland. These lesions rarely transform into malignancy but are locally infiltrative and can lead to haemorrhage. Therefore, plexiform neurofibroma should always be considered during differential diagnosis while excising a submandibular gland mass. We present here ...

Saliva is of major importance in taste, speech, swallowing, and protection against dental caries. Neck dissection surgery and/or radiotherapy may impair the function of the submandibular glands. Over the years, there has been a trend toward more conservative approaches to neck dissection. Metastasis to the submandibular gland itself is extremely rare and if removal of the lymph nodes of subleve...

A case of 42 years-old man with bilateral big sized (12 x 5 cm and 10 x 4,5 cm) oncocytoma in submandibular glands was presented. Oncocytoma is a rare benign neoplasm observed in numerous of organs. In the case described besides submandibular glands tumours, accessory oncocytic tumours in both kidneys were diagnosed. It was the reason of earlier unilateral nephrectomy. Surgical treatment was ap...

Sialolithiasis is one of the most common pathologies of the submandibular gland; sialoliths account for about 80 percent of all salivary duct calculi.The majority of sialolith occurs in the submandibular gland or its duct and is common cause of acute and chronic infection. Salivary stones larger than 15 mm are classified as giant sialoliths. They are uncommon in the practice of otolaryngology, ...

Aluminum absorption leads to deposits in several tissues. In this study, we have investigated, to our knowledge for the first time, aluminum deposition in the salivary glands in addition to the resultant cellular changes in the parotid and submandibular salivary glands in a model of chronic intoxication with aluminum citrate in rats. Aluminum deposits were observed in the parotid and submandibu...
