Diagnostic Challenge of a Deep Minor Salivary Gland Neoplasm
Core needle biopsy represents a safe and cheap alternative diagnostic method to open biopsy and fine-needle aspiration cytology in head and neck tumors. There is little evidence in the literature about the use of core needle biopsy in minor salivary gland lesions. This single case report presents a 60-year-old woman with a painless swelling in the soft palate, breathing and swallowing difficult...
متن کاملMalignant melanoma of unknown primary site simulating a salivary gland neoplasm.
Malignant melanoma with its varied clinical presentations and histomorphological patterns is a perplexing problem both for the diagnosticians and clinicians. A small proportion of melanomas present with metastatic tumors with unknown primary sites and at these sites they mimic the more common primary neoplasms. We hereby report a case of malignant melanoma presenting as a submandibular lump in ...
متن کاملMetastatic renal cell carcinoma of the buccal mucosa masquerading as a salivary gland neoplasm
Metastasis to the oral cavity is a rare occurrence with renal cell carcinoma (RCC) being the third most common tumor to metastasize to this location. Buccal mucosa is rarely involved and in the absence of a known primary, such lesions pose a diagnostic challenge to the pathologist. The histomorphological features may mimic a primary salivary gland neoplasm adding to the dilemma. We present one ...
متن کاملConsistent absence of BRAF mutations in salivary gland carcinomas
Introduction: Malignant salivary gland tumors are rare entities. Despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. The activation of EGFR- RAS-RAF signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic m...
متن کاملA Review of Signet Ring cells in Salivary Gland Tumors
Objectives: Signet Ring Cells (SRCs) are often seen in gastrointestinal, breast, bile duct and lung invasive carcinomas. Observing these cells in benign and malignant lesions of the salivary glands is not common. Signet-ring cell adenocarcinoma is rare and is commonly seen in the secondary salivary glands. Although, the presence of SRCs in other neoplasms of the body is usually associated with ...
