Schwannoma is a solitary, benign tumour arising from the neural sheath Schwann cells of the peripheral, cranial or autonomic nerves. In the head and neck region, it occurs most commonly in association with the acoustic nerve within the skull and is rarely found in oral structures. When it is found in oral structures, the tongue is reported to be the favoured site. Schwannoma of the tonsil is extremely rare, with only two cases reported in the literature. We report what is, to our knowledge, the third case of schwannoma of the tonsil, diagnosed by histopathology.
The most common offending allergen in our study was the dust mite. Identification of specific allergens for a particular geographical area aids patient education and enables allergen-specific immunotherapy.
Sebaceous adenomas in the oral cavity are very rare, with only 10 cases previously reported in the English language literature. Sebaceous adenoma of the palate has not previously been reported, to our knowledge. We discuss the role of special stains and immunohistochemistry in the diagnosis of this tumour.
We report a rare case of type II first branchial cleft cyst that presented as an intraparotid cyst. Rarity and varied presentations of the first branchial cleft cysts have led to frequent misdiagnosis. High index of suspicion is required. Complete excision is the main treatment.
Introduction
Epidermoid cyst is a rare cyst in head and neck region. We report a case of epidermoid cyst of tongue presented in a girl child.
Case report
A female child presented with a swelling in her tongue. The swelling was excised completely. A diagnosis of epidermoid cyst of tongue was made. The diagnosis was confirmed by histopathology. There was no recurrence after 6 months follow-up.
Conclusion
Epidermoid cyst of tongue is a rare tumor of tongue. Complete excision does not cause recurrence.
Schwannoma is one of the benign nerve sheath tumor which may arise from any myelinated nerve.
It is a truely encapsulated neoplasm of the human body and always solitary. It occurs only 1 -2% intraorally inwhich tongue is being the most common site. This article reports a case of schwannoma on the right lateral aspect of the tongue in a 27 year old female patient and its diagnosis and management.
I.
Intoduction:Schwannoma (Neurilemmoma) is a benign tumor of nerve sheath origin. These tumors can arise from any nerve covered with a Schwann cell sheath, which include the cranial nerves(except for the optic and olfactory), the spinal nerves and the autonomic nervous system. The tumor cells always stay on the outside of the nerve, but the tumor itself may either push the nerve aside or up against a bony structure, thereby causing damage to the affected nerve. Head and Neck schwannomas represents approximately 25 -45%, but only 1% have an intraoral origin. Intraoral schwannoma commonly occur in the tongue followed by the palate, floor of the mouth, buccal mucosa and mandible.11 Schwannoma of tongue the typically occurs in the 3 rd decade of life with no sex predilection.
II. Case ReportA 27 year old female patient visited the Dental department with the chief complaint of growth in the right side of the tongue for the past 6 months. The growth was progressive in nature and painless. There was no history of trauma or local infection. On intraoral examination 2×2 cm growth was seen on the right lateral border of the tongue. On palpation, the growth was firm, non tender, smooth, and found to be covered with normal lingual mucosa. Tongue movements were normal. There was no cervical lymphadenopathy. Routine blood investigation was performed. All parameters were within normal limits.Management: Under aseptic conditions, the growth was removed by complete excision under Local anesthesia and the specimen was sent for histopathological examination. The postoperative course was uneventful. The movement of the tongue was normal.
Histopathological Examination:Histopathological report revealed a well encapsulated predominantly spindle cell having dimorphic pattern of Antoni A and Antoni B type cells suggestive of Schwannoma. Areas of palisading arrangement of nuclei suggestive of verocay bodies was also noted.
