The authors describe the case of a 58 years old man, affected by severe obesity, alcohol addict, observed because of a retromandibular mass, measuring 6 cm. Clinical and instrumental findings indicated the presence of a mass apparently due to a parotid abscess; no evident lesions appeared at the examination of the ENT regions.
