Osseous choristomas are rare benign lesions characterized by ectopic bone formation in the soft tissue of the head and neck region. Dermoscopy visualizes the morphological characteristics that are not observable by the naked eye, and may be used for the evaluation of calcification under the skin. The present study reports a case of an osseous choristoma arising in the tongue, and reveals the de...

  Introduction: Choristoma is defined as the presence of cells in abnormal locations due to defects during embryological development. The word choristoma implies a neoplasm; whereas heterotopia refers to a displaced tissue without necessarily being a swelling or a neoplasm. Literature contains reports of cartilaginous choristoma in the cervix, endometrium, breast tissue, and oral region.   ...

Choristoma, also known as a hairy polyp, is rare benign mass that commonly occurs in the nasopharynx and oropharynx head neck region. It usually diagnosed children has rarely been reported adults. In this study, we describe nasopharyngeal choristoma an adult man. The was located at lateral wall, patient expressed intermittent nasal stuffiness ear fullness. successfully removed using endoscopic ...

Osseous choristoma is a normal bone tissue in an ectopic position. In the oral region lingual localization occurs more frequently and the mass is generally localized on the dorsum of the tongue. Definitive diagnosis is obtained only after histopathologic examination. The etiology remains already debatable. The treatment of choice is surgical excision. In this paper we present a case of tongue o...

UNLABELLED Salivary gland choristoma (SGCh) is defined as the presence of normal salivary tissue in an abnormal location. It is a rare entity in oral and maxillofacial region and its ethiology is unknown. The typical presentation of salivary gland heterotopia is an asymptomatic mass that may or may not produce saliva. Some examples of ectopic salivary tissue in the pituitary gland, in the lymph...

Salivary gland choristoma of the middle ear cavity is a very rare condition. These lesions are a result of a defective embryonic development and their adjacent structures may be associated with abnormalities. Here we report a case of salivary gland choristoma of the middle ear who presented to Be’sat Hospital, Tehran, Iran in 2015 with unilateral conductive hearing loss. There are 41 case repor...

Choristoma is development of a normal tissue in an aberrant location. This report describes jejunal salivary choristoma (JSC) causing recurring episodes of abdominal discomfort in a 5-year-old girl. Exploratory laporatomy revealed a pale yellow subserosal jejunal lesion. Wedge resection of the lesion and repair of the bowel were performed. The child did well postoperatively and has since that t...

A choristoma or heterotopias is an aggregate of microscopically normal cells or tissues which occurs in aberrant locations. A choristoma is a tumour like mass, whereas heterotopias refers to a displaced tissue which is necessarily not a swelling or a neoplasm. We are reporting a case of a 24 year old female who presented with recurrent tonsillitis and halitosis. On examination, the tonsils were...

A child born of a full-term pregnancy had unilateral splitting of the anterior segment of the right eye associated with choristoma. No other craniofacial abnormalitieswere found.
