Sialolithiasis - A case report

Sialolithiasis is the occurrence of calcified structure within the ductal system or gland formed by the deposition of calcium salts around a central nidus consisting of desquamated epithelial cells, bacteria, foreign bodies, etc. Sometimes it presents as a diffuse swelling that simulates cellulitis, occasionally asymptomatic where only a firm swelling is palpable along the course of the duct or near the orifice, very rarely outside the ductal system through the eroded ductal wall. Since chewing promotes release of saliva, symptoms tend to increase during meals. A palpable lump or visible swelling in the area of the gland is often noted. Complications include persistent obstruction of the duct, leading to bacterial invasion, overgrowth and infection (sialoadenitis).
