Abstract
Sialolithiasis is one of the most common condition affecting the major salivary glands. This benign disorder is characterized by a partial or complete obstruction of the salivary glands or their ducts.
More than 80 % of salivary calculi occur in the submandibular ductal system. Parotid gland involvement is relatively rare, accounting for 5–10 % of cases. Its diagnosis is particularly challenging for the practitioners, which can lead to delayed diagnosis.
The aim of this article is to report a case of parotid sialolithiasis in Stenon’s duct, diagnosed late after four years of recurrent acute sialadenitis episodes.

Introduction
Sialolithiasis, also known as salivary stones, is a benign disorder involving the formation of stones within the ducts of the salivary glands [ ]. This leads to salivary stasis, glandular swelling and potentially chronic infection [ ] .
Parotid sialothiasis is rare, accounting for 6 %–15 % of all salivary stone cases [ ]. It affects about 1 % of the population [ ], and it is more prevalent in adults between the ages of 30 and 60 [ , ], with men affected twice as often as women [ ].
This article aims to present a case of parotid sialolithiasis, located in the Stenon’s duct, diagnosed after four years of recurrent acute sialadenitis episodes, and managed surgically.

Case presentation
A 56-year-old patient, presented to the department of oral surgery of the dental consultation and treatment center in Casablanca, with a history of kidney stone removal.
She complained of painful swelling in the left parotid region, with recurrent inflammatory and infectious episodes of the parotid over the past four year, which resolved with antibiotics. The patient reported an exacerbation of pain during meals, and a relief through massage and pressure on the parotid area. She had multiples consultations and radiological exams, but no significant findings were observed.
Clinical examination showed swelling in the left parotid region, with painful palpation and pus discharge from an enlarged Stenon’ s duct, revealing a mobile stony hard mass ( Fig. 1 ).
CT scanner revealed a radio-opaque image in the lateral region of the left cheek, associated with thickening of the adjacent soft tissues ( Fig. 2 ).
