Coexistence of salivary gland cysticercosis with squamous cell carcinoma of the mandible

Cysticercosis is a parasitic infestation caused by the pork tapeworm larval stage, Cysticercus cellulosae. The majority of the cases present in ocular, cerebral, and subcutaneous locations. We report the presence of cysticercosis inside the submandibular gland in association with squamous cell carcinoma of the inferior alveolar ramus of the mandible. To the best of our knowledge, this is the first case report documenting cysticercosis inside a salivary gland. A 65-year-old male presented with complaints of an ulcerative lesion on the inferior alveolar ramus present for 2 months. Histological examination revealed a keratinizing well-differentiated squamous cell carcinoma involving the alveolar margin and mandible. The histopathological examination of the submandibular gland revealed cysticercosis. This case emphasizes the importance of adequate sampling of all the tissues obtained for associated infectious disorders, more so in immunosuppressed patients, which will help the clinician to manage the case appropriately.
