metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. metastasis from thyroid gland is extremely rare to oral region. we present an unusual case of metastatic follicular carcinoma of thyroid in max...
Metastasis of Non-Hodgkin\'s T-cell lymphoma to the palate and maxillary alveolar ridge: case report

Lymphomas are neoplastic growth of lymphocytes caused by organisms like EBV, HIV, etc. This malignancy is classified as Hodgkin’s lymphoma and non-Hodgkin’s lymphoma.

BACKGROUND Oral cancer survival rates increase significantly when it is detected and treated early. Unfortunately, clinicians now lack tests which easily and reliably distinguish pre-malignant oral lesions from those already transitioned to malignancy. A test for proteins, ones found in non-invasively-collected whole saliva and whose abundances distinguish these lesion types, would meet this cr...
Intraocular melanomas, among the most com mon eye tumors in man, have seldom been reported in animals. This is particularly surprising in regard to the dog, a species that usually lives well into the "tumor age" and is affected by diverse neoplasms. In his "Pathology of Tumours" (1953) Willis (48) stated : ' 'I have not read of an intraocular melano ma in an animal." While reported cases are no...
BACKGROUND In the present study, the reliability of oral brush biopsy in identifying dysplasia in clinically diagnosed oral potentially malignant and malignant lesions was evaluated while comparing the findings with scalpel biopsy in terms of sensitivity and specificity. MATERIALS AND METHODS In our study, a total number of 50 patients that included both premalignant and malignant lesions wer...
OBJECTIVE In a previous article, we reported the prevalence rates of oral mucosal lesions in this hospital from 1990-2001. This study was planned to study the spectrum of potentially malignant and malignant oral lesions in Allahabad, North India in the subsequent years till 2007 and to assess change in pattern of prevalence, if any.

BACKGROUND Qat (also known as Khat, Kat and Miraa) is a green-leaved plant (Catha edulis). It is a shrub indigenous to Yemen and certain parts of eastern Africa. Chewing the leaves, which have sympathomimetic and euphoric effects, has been documented in many countries and increased with worldwide migration. The effect of long-term chewing Qat on the oral cavity is unknown. OBJECTIVE A systema...
Introduction: Early diagnosis of malignant and premalignant lesions of oral mucosa has a definitive role in promotion of prognosis and life span of patients. This study aimed to investigate how accurate is a clinician‘s doubt regarding existence of premalignant and malignant of oral mucosal via the correspondence between clinical differential diagnosis and histopathologic diagnosis. Furthermore...
