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...

Extracranial meningiomas of the head and neck region are rare neoplasms, the majority being a secondary location of a primary intracranial tumour. We herewith report three rare cases of extracranial meningiomas, located in the temporal muscle, parotid gland and nasal cavity, together with complete pathological, immunohistochemical and ultrastructural studies. Prognosis of this tumour is general...

The authors report a case of a 60-year-old woman presenting with a renal cell carcinoma in which the first sign leading to its diagnosis was a cervical metastasis, an uncommon site of distant disease in renal neoplasms. The patient had an 18-month history of a progressively enlarging cervical mass at the anterior aspect of the neck. After laboratory and radiological evaluation, the cervical mas...

This is a case report of a previously undescribed 20q chromosomal deletion (del(20q)) in marginal zone lymphoma (MZL). A 54-year-old Caucasian male presented with an enlarging neck mass and multiple violaceous skin nodules over his chest. Biopsy of the neck mass and cervical lymph nodes revealed MZL. Cytogenetic evaluation of both lymph node and bone marrow tissue revealed del(20q). This was an...

Osteoblastomas are rare neoplasms of the spine. The majority of the spinal lesions arise from the posterior elements and involvement of the corpus is usually by extension through the pedicles. An extremely rare case of isolated C2 corpus osteoblastoma is presented herein. A 9-year-old boy who presented with neck pain and spasmodic torticollis was shown to have a lesion within the corpus of C2. ...

Soft tissue myoepithelial neoplasms are a rare yet diverse group of tumors, ranging from benign to malignant lesions. Their presentation in the head and neck region is uncommon and represents a challenging diagnosis. Early identification of myoepithelial carcinoma is crucial given its more aggressive course compared to its benign counterpart, although the histopathological distinction between t...

Testicular teratomas may present in both prepubertal and adult males. The prognosis differs greatly between these two groups. In children, teratomas most often occur before the age of four. They are seen in their pure form, and behave a benign behavior. In adults, teratomas are usually part of a mixed GCTs, and have the potential to metastasize. The presence of neck metastasis in patients with ...

The objective of this article is to provide the internist with general considerations when confronted with an adult patient presenting with a neck mass. A thorough gathering of historical information and a complete physical examination are crucial in developing a differential diagnosis for these patients. Specifically, the location of the mass, its time of onset, and duration are important beca...

Salivary gland tumours are estimated to represent approximately 3% of all head and neck tumours. About 70-80% of these neoplasms occur in the major salivary glands, with the parotid gland being the most commonly affected site. The metastasizing pleomorphic adenoma (MPA) has histological characteristics of pleomorphic adenoma, but it has the capacity to generate local recurrences and distant met...
