Chronic apical periodontitis associated with dental pulp necrosis is the main cause of odontogenic extraoral cutaneous sinus openings. These tracts are often initially misdiagnosed unless the treating clinician considers a dental aetiology. This case report of a 19-year-old woman describes the diagnosis and treatment of an extraoral cutaneous sinus tract of odontogenic origin. Non-surgical conservative endodontic therapy was opted as the involved teeth were restorable. One month after the completion of obturation, there was closure of the sinus tract. One year follow-up showed complete resolution of the sinus tract with minimal scar formation.

Pleomorphic adenoma, otherwise called as benign mixed tumour, is the most common salivary gland tumour which accounts for 60% of all benign salivary gland tumours. The clinical, radiological and histopathological presentations are varied. The tumour occurs in diverse anatomical sites and can consist of epithelial and mesenchymal components. In this case report, the patient reported with an asymptomatic swelling on the face. CT scan with contrast was advised. The clinical, roentgenographic findings and Fine Needle Aspiration Cytology were indicative of pleomorphic adenoma of the parotid gland. Treatment included partial superficial parotidectomy under general anaesthesia using the modified Blair’s incision. The facial nerve was not involved. Part of the gland along with the tumour was resected completely superficial to the facial nerve with a margin of normal tissue all around. Histopathologic examination of tissue specimen confirmed the lesion as pleomorphic adenoma. The patient was asymptomatic at 6-month follow-up.

Background: Literature survey indicates that intraosseous transmigration is uncommon. Transmigration of mandibular premolars to distant sites like the ramus are rare and is often detected by chance. Case description:A 19-year-old female reported seeking replacement of her missing teeth. Clinical examination showed multiple missing teeth and a history of early loss of permanent molars. Panoramic radiographs revealed a transmigrated mandibular premolar in the ramus of the mandible surrounded by well a circumscribed radiolucent area.Practical implications: Transmigrated premolars in the ramus can cause complications like cystic lesions, weakened ramus, and susceptibility to fracture. Young females undergoing early extraction of permanent molars are at increased risk.
