Oral squamous cells carcinomas (OSCCs) accounts for approximately 95% of all oral malignant neoplasms and for about 38% of all malignant head and neck tumors, especially the tongue and lip (Jones et al., 1992; Brandwein-Gensler et al., 2005; Bell et al., 2007). Unfortunately, the increase in incidence has not been paralleled by the development of new therapeutic agents and the 5-year survival r...

RESULTS: Between1998-2010, 85 cases with ESRD on dialysis and 841 controls without ESRD were analyzed. Majority of patients were aged ≦65 years (82.5%) and 92.9% were men. The major subdivision of head/neck cancer was neoplasm of other and unspecified parts of the mouth followed by neoplasm of tongue, the gum, hypopharynx and floor of mouth. ESRD patients tended to have higher rates of DM and P...

Granular cell tumor (GCT) is a rare submucosal neoplasm most commonly localized in the oral mucosa; with one-third of all cases found in the tongue, with less than 30 cases of perianal GCT reported in the literature, making it a rare anal neoplasm. Wide local excision is the gold standard of treatment and follow-up includes annual colonoscopy due to the high incidence of reoccurrence. Here we d...

Myofibroma is an uncommon spindle cell neoplasm rarely found in oral cavity. Typically, this lesion is seen in neonates and infants with few cases reported in adults patients. In the oral cavity, myofibroma occurs within the submucosal or intramuscular tissue and has a predilection by the tongue, buccal mucosa and lips. Microscopically, a typical biphasic pattern can be observed. Misdiagnosis i...

Adenoid cystic carcinoma (ACC) occurs more commonly in the minor salivary glands of the palate on than the tongue. ACC is a malignant neoplasm that accounts for 1-2% of all head and neck malignancies and 10-15% of all salivary gland malignancies. ACC affects the exocrine glands at any site, but the parotid gland is the most common site in the head and neck region. Many factors should be taken i...

Langerhans cell sarcoma (LCS), a rare malignant disease with markedly malignant cytological features and poor outcome, originates from Langerhans cells and most commonly affects the lymph nodes, skin, and bone. This paper presents the case of a 58-year-old female with LCS at the root of her tongue, with neither local recurrence nor distant metastasis observed during 47 months of follow up follo...

Hyalinizing clear cell carcinoma is a rare, low-grade neoplasm of the minor salivary glands. It is composed exclusively of epithelial cells with optically clear cytoplasm. There are only a few isolated cases reported in the literature involving the base of tongue. The treatment of choice is wide excision and selective neck dissection, with or without radiotherapy. The prognosis of these tumours...

Basaloid squamous cell carcinoma is a recently recognized, rare and aggressive variant of squamous cell carcinoma with a predilection to occur in base of the tongue, hypopharynx and larynx (especially the supraglottic tract). It is usually diagnosed in advanced stage, frequently with distant metastases, requiring aggressive surgical intervention. The prognosis is remarkably poor even after the ...

Synovial sarcoma is an uncommon neoplasm accounting between 8 and 10% of all soft tissue malignancies. Involvement of the head and neck region is rare. So far, fewer than 100 cases have been reported in the literature and only a few originated in the soft palate, tongue, larynx, hypopharynx, and cervical oesophagus. We report the case of a synovial sarcoma of the parapharyngeal space in a 72-ye...

OBJECTIVES Squamous cell carcinoma (SCC) is the most common malignant neoplasm of the oral cavity and a public health threat. Tumor progression is believed to be influenced by angiogenesis as well as tumor cell proliferation; however, the correlation of these two factors in tongue SCC still remains unclear. This study aimed to assess the correlation of these two factors in tongue SCC. MATERIA...
