Epidermoid cyst of the floor of the mouth

Dermoid cysts are malformations that are rarely seen in the oral cavity. An intraoral dermoid cyst grows slowly, but may enlarge and interfere with deglutition and speech, or can pose a critical risk to the airway and therefore require immediate surgical intervention. Dermoid cysts may develop above or below the mylohyoid muscle, causing a submental or submandibular swelling. Surgical excision is the treatment of choice and recurrence is rare. An intraoral approach for the treatment of large lesions presenting above the mylohyoid muscle provides good cosmetic and functional results. We report a case of a 26-year-old female who developed an epidermoid cyst presenting as a large sublingual swelling causing speech and swallowing difficulties. The lesion was surgically excised using an intraoral approach. Microscopic examination revealed a dermoid cyst of the epidermoid type. This case shows that dermoid cysts may be successfully diagnosed and managed using a series of simple yet effective clinical procedure.

Melanocytoma of cerebellum.

Melanocytomas are rare melanocytic tumors of the central nervous system. We report a rare case of melanocytoma in the cerebellum of a 35-year-old male patient. Computed tomography scan showed a cystic lesion with an enhancing solid component arising from the cerebellum. The lesion was resected and a histological diagnosis of melanocytoma of the cerebellum was made.

Paraganglioma of left cerebellopontine angle

Paraganglioma is a rare tumor of the cerebellopontine angle. We report a case of a 55-year-old female presented with otalgia and decreased hearing in the left ear, hoarseness of voice, difficulty in swallowing, nasal regurgitation, and tinnitus. The tumor was excised by left retromastoid and posterior fossa craniectomy approach. Intra-operative crush smear and histopathological examination revealed a paraganglioma. Post-surgery the patient was treated with fractionated radiotherapy.
