Acinic cell carcinoma arising in salivary glands is a rare tumor, accounting for 2% to 5% of the primary neoplasms of the parotid gland. When these tumors are well-differentiated, the neoplasia has innocuous aspect, due to the similarity to normal parotid tissue. This makes the diagnosis difficult. Initially the malignancy of this tumor was uncertain; however, recent studies have declared it as...

Objective/background. This is a case presentation of a primary multifocal monomorphic and pleomorphic adenoma, with possible association with myotonic dystrophy. Methods/presentation. The patient was a 36-year old woman with myotonic dystrophy with multiple left parotid masses. Biopsy and final pathology demonstrated discrete de novo pleomorphic and monomorphic adenomas. Conclusions/impact. The...

Background: To study the clinical presentation, cytological and histopathological variants in acinic cell carcinomas (ACC) of parotid gland admitted Yenepoya medical college.Methods: This is a retrospective done over period 5 years from January 2015 to December 2019 on patients with swellings college hospital. All diagnosed as ACC examination were considered study.Results: Out 60 swelling, have...

The intimate anatomical relationship of the facial nerve to the parotid parenchyma has a significant influence on the presenting signs and symptoms, diagnosis and treatment of parotid neoplasms. However, to our knowledge, hyperactivity of this nerve, presenting as facial spasm, has never been described as the presenting sign or symptom of a parotid malignancy. We report a case of carcinoma aris...

Hemangiopericytomas are uncommon neoplasms of vascular origin that mostly arise from extremities, retroperitoneum, and pelvic fossa. They are rarely found in the parotid gland. A 35-year-old female patient presented with a swelling in the right preauricular region. Fine-needle aspiration biopsy performed twice yielded an extraordinary amount of blood. A cytological diagnosis could not be made. ...

Lipomas are common soft tissue neoplasms; however, they are found rarely in the parotid gland region. The purpose of this study was to analyze the diagnostic challenges of this rare condition. We performed a retrospective analysis of 11 patients with parotid lipomas, treated from November 2009 to February 2014. The mean age at diagnosis was 46.6 ± 2.9 years, and the study population included 8 ...

Salivary gland cancers are uncommon malignancies of the head and neck region. Their site of origin can be major (parotid, submandibular and sublingual) or minor salivary gland (palate, nasal cavity, paranasal sinuses, trachea and lacrimal gland). Of all the salivary gland neoplasms, 85% are benign and 15% are malignant. Salivary gland malignancies comprise 3-6% of all head and neck cancers (Pin...

Most salivary gland tumors are benign, malignant lesions accounting for 15-30% of the total. The most frequent site of salivary gland neoplasms is the parotid gland (80% of all cases). We present a case of malignant fibrohistiocytoma with atypical features due to its location (in the parotid region), size and rapid growth. Generally, this type of tumor arises in the lower limbs and in the abdom...

Malignancies of the parotid gland are relatively uncommon, accounting for only 3-6% of all head and neck cancers. Most of them are primary neoplasms, metastases are uncommon. Renal cell carcinoma (RCC) represents 3% of adult malignancies, the clear cell type comprises up to 70% of all RCC. RCC has an unpredictable behavior and the unique potential to metastasize to nearly every organ in the bod...
