Salivary gland choristoma (heterotopic salivary gland tissue) is a rare condition typically seen in the newborn period. This developmental heterotopia is generally nonprogressive, with little risk of malignant transformation. We present the second known reported case of a salivary gland choristoma located on the anterior chest wall. Knowledge of this rare entity will allow for accurate diagnosi...

The cartilaginous choristoma in children is very rare in literature. Its treatment is complete surgical removal as promptly as possible in order to get an exact histopathological diagnosis. In this study we present and discuss a 10mo-old girl with cartilaginous choristoma located subcutaneously just on the left sternocleidomastoid muscle without any associated anomalies such as branchial remnants.

FROM time to time in post-mortem reports, a small tumour of the posterior pituitary stalk, called a choristoma, is an incidental finding. Looking through the reports of the Pathology Department of Queen's University, it was possible to find thirty cases of choristoma over the past twenty years. The tumour was first noticed by Boyce and Beadle in 1893, but was called "Choristoma" by Sternberg in...

Glial choristoma is considered to be a type of brain heterotopia consisting of ectopic central nervous tissue. We herein report a neonate with glial choristoma of the tongue who developed respiratory distress due to airway obstruction. A male neonate presented with respiratory distress due to a soft mass on the midline region of the dorsal tongue base at birth. He was intubated using a flexible...

Osseous choristoma is a rare, benign lesion of the oral cavity occurring usually in the tongue. It appears as a tumorous mass of normal bony structure with mature cells in an ectopic position. The case of a 72 years Caucasian male is presented and analyzed along with 52 similar cases reported in the English literature between 1967 and 2007. Lingual choristoma shows a female predilection, wherea...

To newly describe the clinical and histopathological characteristics of epibulbar complex cartilaginous choristoma incidentally observed in a series of pterygium excision patients.Noncomparative case series with chart review of 8 patients.During a 4-year period, we identified 8 cases of conventional unilateral nasal subpterygial cartilaginous choristoma in 1799 pterygium patients and analyzed t...

Purpose To present the case of a 12-year-old female with an epibulbar osseous choristoma. Observations The patient presented with right-sided conjunctival mass, which caused her discomfort. Slit lamp examination revealed a 5×5-mm, firm nodule in the superotemporal quadrant of the bulbar conjunctiva. The nodule had feeder vessels, adhered firmly to the sclera, and lacked signs of malignancy. T...

An osseous choristoma is a rare benign lesion consisting of normal bone tissue; it is seen in abnormal locations. It is most often seen in the posterior 1/3 of the tongue in the head. Its etiopatogenesis is controversial, and till date, less than 100 cases have been reported in the literature. Although a lingual osseous choristoma is asymptomatic, in some patients, symptoms such as swelling sen...

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.   case r...
