Extraskeletal myxoid chondrosarcoma (EMC) is a malignant soft-tissue neoplasm rarely described in the head and neck region of children and adolescents. We describe a case of EMC affecting the masticator space and a literature review. A 13-year-old boy who presented a large painless, diffuse mass causing progressive midfacial asymmetry of 6 months duration. Histopathological evaluation revealed ...

Introduction. Rhabdomyomas of the head and neck are exceptionally rare benign mesenchymal tumors. Rare cases have been reported to involve other sites of the body including the head and neck regions. Case Presentation. We report a case of voluminous extracardiac adult rhabdomyoma affecting adult patients and initially seen as slowly growing, indolent neoplasms. The patient is a seventy-year old...

BACKGROUND Commonly occurring in the head and neck, paragangliomas are typically benign, highly vascular neoplasms embryologically originating from the extra-adrenal paraganglia of the neural crest. Frequently, these tumors are associated with the vagus or tympanic plexus nerve or the carotid artery, or jugular bulb. Their clinical presentation can vary across a wide spectrum of signs and sympt...

Head and neck squamous cell carcinomas are among the most common neoplasms worldwide and characterized by local tumor aggressiveness, high rate of early recurrences, development of metastasis, and second primary cancers. Despite modern therapeutic strategies and sophisticated surgical management, overall survival-rates remained largely unchanged over the last decades. Thus, the need for novel t...

Autosomal Dominant Chronic Mucocutaneous Candidiasis (AD-CMC) is characterized by defective T cell immunity, leading to fungal infections limited to mucosal surfaces. Recently it was discovered that mutations in the coiled-coil (CC) domain of STAT1 are the cause of AD-CMC. STAT1 deficiency has been implicated in experimental models of oesophageal cancer (EC) and head and neck carcinoma (HNC). B...

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...

Cancer, a disease of an uncontrolled cell division, growth and metastasis as a result of genetic mutations, environmental factors and host response, is affecting populations worldwide. Etiology, pathogenicity, and genetics related to cancer are not well understood, and treatment has not been as effective as scientists have expected. Continual research is being done to improve current understand...

BACKGROUND Core needle biopsy (CNB) has gained acceptance as a minimally invasive procedure in the head and neck. Nevertheless, many concerns arise regarding the value and safety of this method in the assessment of salivary gland lesions. METHODS This prospective study comprises 111 patients with a salivary gland lesion. The results of ultrasound-guided CNB were compared with those of fine-ne...

Ectopic internal carotid artery (ICA) is a very rare variation. The major congenital abnormalities of the ICA can be classified as agenesis, aplasia and hypoplasia, and they can be unilateral or bilateral. Anomalies of the neck artery may be vascular neoplasms or ectopic position. Carotid angiograms provide absolute confirmation of an aberrant carotid artery, while EcoColorDoppler (ECD) gives a...
