Abstract Background The unilateral submandibular gland aplasia (agenesis) is a rare, asymptomatic condition usually discovered incidentally on imaging. This associated commonly with either compensatory hypertrophy of contralateral or sublingual glands. Case presentation We report the case 34-year-old male detected ipsilateral gland, demonstrated by imaging modalities, where we have highlighted ...
Galectin-1 (Gal-1) is a beta-galactose-binding lectin; its expression level has been reported to correlate with tumor progression. Gal-1 is highly expressed in the invasive front of primary tumors and in the cancer cells of metastatic lesions in the lymph nodes of patients with oral squamous cell carcinoma. However, the molecular mechanism of Gal-1 in tumor metastasis is not completely clear. W...
Cancer of the tongue or the floor of the mouth sometimes metastasizes to the lingual lymph node. We present two patients with squamous cell carcinoma of the floor of the mouth who developed metastases to the lateral lingual lymph nodes. Case 1, a 62-year old male, had squamous cell carcinoma of the floor of the mouth (T3N2cM0). He underwent tumor resection and bilateral neck dissection, and his...
PURPOSE Despite advances in our understanding, prevention, and treatment of head and neck squamous cell carcinoma (SCC), the 5-year survival rates for patients remain low. This poor prognosis for head and neck SCC and SCC of the oral tongue (SCCOT) in particular reflects a limited understanding of the mechanisms of local and regional metastasis, which accounts for a majority of deaths. To analy...
Mandibular metastatic carcinoma is a rare lesion that accounts for <1% of all oral malignancies. To provide greater experience in this field, the present study was conducted in which 6 cases of mandibular metastatic carcinoma were retrospectively reviewed. The origin of the lesions was the prostate in 2 cases, the lungs in 2 cases, the breast in 1 case and the thyroid gland in 1 case. The clini...
Diagnosing gingival metastases is difficult because clinically they can mimic benign oral lesions. The authors report an unusual case of metastatic ovarian carcinoma in the gingiva of a 46-year-old woman 5 years after ovariectomy. The tumor presented as an exophytic growth at the molar region of the mandible. Histological examination showed invasive proliferation of atypical glandular structure...
A 70-year-old man with metastatic renal cell carcinoma developed progressive liver metastases after 8 weeks of treatment with the multitargeted tyrosine kinase inhibitor (TKI) sunitinib. He then participated in the phase III placebo-controlled clinical trial of the oral mammalian target of rapamycin (mTOR) inhibitor everolimus, initially randomized to placebo (but had disease progression after ...
In an era where mutational profiles inform treatment options, it is critical to know the extent to which tumor biopsies represent the molecular profile of the primary and metastatic tumor. Head and neck squamous cell carcinoma (HNSCC) arise primarily in the mucosal lining of oral cavity and oropharynx. Despite aggressive therapy the 5-year survival rate is at 50%. The primary objective of this ...
to evaluate the effect of adding neoadjuvant chemotherapy to surgery and radiation therapy for locally advanced resectable oral cavity squamous cell carcinoma, 24 patients with t3 or t4a oral cavity squamous cell carcinoma were randomly assigned to surgery alone or docetaxel, cisplatin, and 5-fu (tpf) induction chemotherapy followed by surgery. all patients were planned to receive chemoradiothe...
