Abstract
Combined tumours are those composed of two benign tumours or a benign and malignant tumour or two malignant tumours occurring within the same tumour population. The incidence of combined tumours is very rare. Due to the rarity of these tumours, their biological behaviour remains unlashed. Incisional biopsy of a 48 years old female patient with single, diffuse tumour mass in the oral cavity showed combined tumour or collision tumour of malignant melanoma and squamous cell carcinoma. This was confirmed with immunohistochemistry study. The incidence of combined tumour of malignant melanoma and squamous cell carcinoma in oral cavity is extremely rare. To the best of our knowledge based on the previous literature records, this is the first case report of its kind where there is incidence in the human oral cavity.
期刊介绍：
The journal of Oral and Maxillofacial Pathology [ISSN:print-(0973-029X, online-1998-393X)] is a tri-annual journal published on behalf of “The Indian Association of Oral and Maxillofacial Pathologists” (IAOMP). The publication of JOMFP was started in the year 1993. The journal publishes papers on a wide spectrum of topics associated with the scope of Oral and Maxillofacial Pathology, also, ensuring scientific merit and quality. It is a comprehensive reading material for the professionals who want to upgrade their diagnostic skills in Oral Diseases; allows exposure to newer topics and methods of research in the Oral-facial Tissues and Pathology. New features allow an open minded thinking and approach to various pathologies. It also encourages authors to showcase quality work done by them and to compile relevant cases which are diagnostically challenging. The Journal takes pride in maintaining the quality of articles and photomicrographs.
