“…[6,7] A study by Buckmiller has demonstrated heterotopic salivary gland in middle ear [8] and in addition Buckmiller et al have suspected the presence of ectopic salivary tissue in middle ear as a component of new syndrome. [8] Other reported sites of involvement are anterior chest wall, cerebellopontine angle, stomach, parathyroid gland, lacrimal gland, pterygopalatine fossa, tonsils, sella turcica, thyroid, mediastinum, rectum, vulva, prostate, gingival, mandible, maxilla, and posterior triangle of the neck. [6,9] In our case, heterotopic salivary gland was found as 3-4 tissue tags on left tonsillar walls.…”

The salivary choristoma or heterotopic salivary gland is defined as a tumor-like growth of otherwise normal salivary gland found in an abnormal location. Although histologically there is evidence of hetertopic salivary gland tissue in palatine tonsil rarely it manifests as visible mass with only isolated case reports having been found. In this article, we present a case with salivary gland choristoma on palatine tonsillar wall and a brief review.

“…Heterotopia involving the salivary gland is found in the various sites of the head and neck including the lower neck [2,3], anterior chest wall [4], gingiva [5] and middle ear [6][7][8][9][10]. Thus, it can be added in the differential diagnosis of the middle ear cavity masses presenting unilateral hearing loss without perforation of the tympanic membrane, which usually include congenital cholesteatoma, glomus tumor, neuroma, dermoid cyst, teratoma and lymphoma.…”

“…Choristoma of the middle ear frequently presents as a mass behind the tympanic membrane situated in the posterosuperior quadrant often associated with ossicular and facial nerve anomalies ( middle ear involvement [13]. It has been proposed by Buckmiller et al [33] that choristoma of the middle ear may represent a component of a new syndrome along with unilateral hearing loss, abnormalities of the incus and/or stapes, and anomalies of the facial nerve. The authors observed that 86% of the reported patients with choristoma have 3-4 of the 4 criteria listed to designate middle ear salivary choristoma as part of a syndrome.…”

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 of the Middle Ear: A Component of a New Syndrome?

Abstract: Eighty-six percent of the reported patients with choristoma have three or four of the four criteria listed to designate middle ear salivary choristoma as part of a syndrome. In the remaining four patients, all of the structures were not assessed.
