This report describes the histopathological features of an ossifying epulis, measuring 1.5 × 1 × 1 cm in length, width and height, respectively, on the lingual surface of the lower jaw of a 2.5 year-old parrot cichlid (Hoplarchus psittacus) from a commercial aquarium. The tumor had appeared in the oral cavity three months prior to its introduction to the laboratory for diagnosis. Grossly, the n...

Background: The incidence of oral cancers is different worldwide. Objective: To evaluate the rate of oral cancers in Khouzestan Province. Patients and Methods: The data were collected from the pathologic reports of pathology laboratories all around the province, during the time period of 1992-2002. Results: Among the total received specimens, 305 cases of oral cancers were detected. One hundred...

introduction: 90% of the tumors in the head and neck are squamous-cell carcinomas (hnscc), which have overall 5- year survival rate between 50% -60%. cd44 has been shown to be associated with the prognosis.  materials and methods: biopsy specimens of 51 patients with oral tongue scc were evaluated by immunohistochemistry (ihc) for the cd44 antibody.  results: there was no significant correlatio...

BACKGROUND Tumor thickness of oral tongue carcinoma is an important independent prognostic factor for local recurrence, subclinical nodal metastasis, and survival. An accurate preoperative assessment of tumor thickness is therefore essential in optimizing treatment algorithm. The present study aims at evaluating the accuracy of intraoral ultrasonography in preoperative measurement of tumor thic...

The majority of patients with oral cancer report intense pain that is only partially managed by current analgesics. Thus, there is a strong need to study mechanisms as well as develop novel analgesics for oral cancer pain. Current study employed an orthotopic tongue cancer model with molecular and non-reflexive behavioral assays to determine possible mechanisms of oral cancer pain. Human oral s...

introduction: daphne species has both pharmaceutical applications and anti tumor activity. it has been shown that the extract of daphne mucronata is effective in decreasing the size of breast adenocarcinoma in rats. we investigated the mechanism of action and the effects of the extract on tnf-a and tnf-a receptors on cultured human monocytes. material and methods: the breast tumors were induced...

abstract   background: squamous cell carcinoma (scc) constitutes the main oral malignancy . parallel to better understanding of molecular and genetic patterns of tumor behavior, more precise correlation of tumor markers such as epidermal growth factor (egf) and laminin-5 are sought to estimate macroscopic and microscopic tumor status .   methods: we conducted a cross-sectional study collecting ...

Picture 1. Oral tumor and chest computed tomography of the patient. (A). Oral finding on ad mission shows upper gingival tumor with bleeding and ulceration. (B). Computed tomography (CT) scan of the chest revealed multiple tumors in bilateral lung bases. (C). Oral tumor was re duced in size immediately 14 days after methotrexate withdrawal. (D). Chest CT on day 41 after withdrawal of MTX shows ...
