Salivary gland choristomata are heterotopic rests which have rarely been reported in the middle ear. A case report of a salivary gland choristoma of the middle ear is presented and the literature reviewed. The frequent association of ossicular chain and facial nerve anomalies is emphasized.

Two cases of osseous choristoma are described. One of the tumours was found in the conjunctiva of the right lower lid, an apparently unique location. The other more typical epibulbar tumour was found in the superior temporal quadrant of the episclera between the lateral and superior rectus muscles. In both instances the tumour was suspected of being a dermoid.

The occurrence of heterotopic gastric tissue in the gallbladder is rare. A choristoma can be defined as a new growth developing from a displaced anlage not normally present in the anatomical site where it developed. We present an extremely uncommon case of a ...

Choristoma is a tumor-like mass consisting of tissues foreign to the site at which they are located. We report an 18 years old male presenting with persistent tonsillitis. Histological examination demonstrated the unexpected presence of a mature island of hyaline cartilage surrounded by lymphoid hyperplasia.

A 45-day-old infant presented with choking spells and cyanosis. Examination revealed a lingual cyst. Contrast-enhanced CT confirmed the diagnosis of lingual cyst with incidental thyroid hemiagenesis. The child underwent excision of the lesion, which was reported as lingual choristoma.
