Sialolith and adenoid cystic carcinoma in the submandibular gland. A rare case

Abstract

Salivary calculi occur most frequently in the submandibular gland of the human beings. It is because of the specific anatomy of both the glands and its duct. Presentation typically consists of a painful swelling of the gland at meal times, when the effect of obstruction is most acute. The clinical signs, in most of times, can lead us to the diagnosis easily. The coexistence of sialolith and malignant tumors are very rare. This case report is about a male patient of 45 year with a swelling in the submandibular region for the last eighteen months with an intermittent episode of moderate to severe pain which increased during a mealtime and diagnosed as sialolith on radiograph, but on biopsy proved to be adenoid cystic carcinoma along with sialolith. This case report describes the coexistence of sialolithiasis and adenoid cystic carcinoma in the submandibular gland with advantages and limitations of various imaging studies to be used by health care professionals prior to reaching definitive conclusion. Key words: Sialolithiasis, Adenoid cystic carcinoma, Submandibular gland, imaging techniques.Nanda KDS, Mehta A. Sialolith and adenoid cystic carcinoma in the submandibular gland. A rare case.

A quite-small adenoid cystic carcinoma in a patient with parotid gland sialolithiasis

“…In the present patient, the quite-small adenoid cystic carcinoma was discovered coincidentally during an operation to remove a sialolith [6,7]. Some previous reports described a case of a large AdCC accompanying submandibular salivary gland sialolithiasis [8,9]. Hasegawa et al reported a case of AdCC complicated with sialolithiasis of the submandibular gland [10].…”

Coexistence of Adenoid Cystic Carcinoma and Sialolithiasis in Submandibular Gland: Case Report

“…The duration of symptoms in some cases with the coexistence of sialolithiasis and salivary gland neoplasm in the literature is remarkable. The swellings duration was 10 years in Miyabe et al’s ( 9 ) and Hasegawa et al’s ( 4 ) cases, 3 years in Gallego et al’s ( 7 ) case, and 1.5 years in Nanda and Mehta's ( 10 ) case. In our study, as in these cases, the swelling was present for a long time (5 years).…”
