“…A search of the archives of the Armed Forces Institute of Pathology identified 110 cases of salivary tissue choristoma in an audit of 20,000 cases of salivary gland lesions; of these, 4 represented cases of choristoma of the middle ear [37]. The first case of middle ear heterotopic salivary gland tissue was reported in 1961 by Taylor and Martin [7]. However, in 1956, Uchytil [38] reported a case of adenoid cystic carcinoma of the tympanic cavity; while entirely speculative, the possibility exists that, in light of modern diagnostic criteria, this lesion might in actuality be interpreted as arisen from a salivary gland choristoma.…”

“…Table 3 is provided to summarize the terminology, diagnostic features and behavior of the various developmental lesions of the head and neck [1]. When the mass is poorly defined and intimately associated with the facial nerve, complete surgical removal is not indicated, especially because the lesion is apparently incapable of further growth, and attempt at removal may result in permanent damage to the facial nerve [7,8]. Only biopsy and observation are recommended in such an instance.…”

While head and neck surgeons are accustomed to recognizing malignancies in their practices, developmental lesions are much less often encountered, and as such are not as likely to be included amongst other (more aggressive) differential diagnostic considerations. One such developmental lesion is the choristoma, defined as an architecturally normal arrangement of mature tissues found in a location not normally host to such tissues. Choristomas composed of recognizable salivary gland tissue may be found in a variety of locations including the middle ear. Middle ear salivary choristomas are distinctly unusual lesions and typically manifest as unilateral conductive hearing loss; while both adult and pediatric patients have been diagnosed with middle ear choristomas, most patients have been in the first two decades of life. As these are benign, nonprogressive lesions, treatment has been directed toward complete surgical excision whenever feasible, and biopsy for diagnosis with subsequent observation in the case of those lesions which are difficult to remove without endangering the facial nerve. There have been rare instances in which choristomas have been linked to the subsequent development of neoplasms, but in the main choristomas are regarded as self-limited developmental heterotopias.

Choristoma is a mass of tissue histologically normal for an organ or part of the body other than the site at which it is located. A rare case of ectopic salivary gland choristoma in the middle ear is described in a 14-year-old girl whose only symptom was a 55 dB conductive hearing loss. The left middle ear mass appeared whitish and was located behind the intact tympanic membrane. We first suspected it to be congenital middle ear cholesteatoma. Exploratory tympanotomy, however, revealed a salivary gland choristoma that adhered tightly to the facial nerve. Differential diagnosis and treatment of this rare condition are discussed.

“…Since Taylor and Martin described salivary gland choristoma of the middle ear cavity in a patient with conductive hearing loss [1], less than 30 cases have been reported in the literature. Because of such rarity, it is very difficult to diagnose this disease preoperatively.…”
