Abstract
A-six-year old male German shepherd dog with swelling and enlargement of the intermandibular and cervical region with a duration of nearly one year was referred to the small animal veterinary hospital, Islamic Azad University of Tabriz. Based on the history, clinical findings, and laboratory investigations, the animal was diagnosed as having cervical mucocele with the involvement of the left sublingual and mandibular salivary glands. Surgical treatment consisting of the excision of the involved gland/duct complex was immediately undertaken with definitive results. Clinical and histopathologic features of this chronic case of canine salivary mucocele are presented in this paper.

Diseases of the salivary glands are rare in small animals, mucocele is the most common clinically recognized disease of these structures in the dog, and the incidence of occurrence has been reported as fewer than 20 in 4000 dogs [5]
Summary
A salivary mucocele or sialocele is an abnormal accumulation of saliva in the subcutaneous tissue adjacent to a damaged salivary gland or duct and is surrounded by granulation tissue. An unusually large and chronic case of cervical mucocele is described in a German shepherd dog. A six-year-old male German shepherd dog was referred to the small animal veterinary hospital, Islamic Azad University of Tabriz with obvious swelling and enlargement of the cervical and intermandibular region. A very large fluctuant, nonpainful fluid filled mass was evident in the cervical and intermandibular region. Aspiration of the mass under aseptic conditions was performed (Figure 1), and a thick mucoid, yellow blood tinged fluid which reacted positively with periodic acid schiff (PAS) stain (Figure 2) confirmed the presence of saliva and a diagnosis of mucocele. After premedication with acepromazine (Alfasan, Woerden, Holland), 0.05 mg/kg and atropine (Iran Pharmaceutical Development and Investment Co., Tehran, Iran), 0.02 mg/kg, anesthesia was induced with 2.5% solution of thiopental (Sandoz GmbH, kundl, Austria) and maintained
