Lingual nerve injury after third molar removal: Unilateral atrophy of fungiform papillae
Background: Pain and sensory changes due to lingual nerve injury are one of the most common alterations that
follow surgical removal of third molar. They are usually transient but other less common complications, such as the
atrophy of fungiform papillae, have an uncertain prognosis.
Case Description: We report a case of a 34-year-old woman who presented a unilateral lingual atrophy of fungiform
papillae after third molar extraction accompanied by severe dysesthesia that altered her daily life significantly during
the following months and how this complication evolved over time. We conducted a literature review on the
different factors that can lead to a lingual nerve injury.
Clinical Implications: The clinical evolution of temporary and permanent somatosensitve injuries is an important
fact to take into consideration during the postoperative management because it will indicate the lesion prognosis
Ghost cell odontogenic carcinoma: a rare case report and review of literature
Objectives: Ghost cell odontogenic carcinoma is a rare condition characterized by ameloblastic-like islands of epithelial cells with aberrant keratinitation in the form of Ghost cell with varying amounts of dysplastic dentina.
Material and Methods: We report a case of a 70 year-old woman with a rapid onset of painful swelling right maxillary tumor. Magnetic resonance showed a huge tumor dependent on the right half of the right hard palate with
invasion of the pterygoid process and focally to the second branch of the trigeminal. Radiological stage was T4N0.
The patient underwent a right subtotal maxillectomy with clear margins. Adjuvant radiotherapy was given. The
patient was free of residual or recurrent disease 12 months after surgery.
Results: The tumor was 3,9cm in diameter. It was spongy and whitish gray. Microscopically the tumor was arranged in nets and trabeculae, occasionally forming palisade. Tumoral cells had clear cytoplasm with vesicular nuclei.
There was atipia and mitosi with vascular and perineural invasion. The excised tumor was diagnosed as a GCOC.
Conclusions: Ghost cell carcinoma is a rare odontogenic carcinoma. Its course is unpredictable, ranging from locally invasive tumors of slow growth to highly aggressive and infiltrative ones. Wide surgical excision with clean
margins is the treatment of choice although its combination with postoperative radiation therapy, with or without
chemotherapy, remains controversial
Myositis ossificans of the masseter muscle: a rare location. Report of a case and review of literature
Background: Myositis Ossificans is a rare heterotopic bone formation within a muscle being the masticatory muscles
exceptionally involved. In most cases there is a previous trauma, bearing in mind that there may be many other
etiologies. CT scan and panoramic radiographs along with histological findings are essential diagnostic aids.
Case Desciption: we report a rare case of MO of masseter muscle in 49 years-old woman after repetitive wisdom
tooth infection with the discussion of clinical, radiological and histological features.
Clinical Implications: MO is a rare disease of masticatory muscles being the masseter the most frequently affected.
Wide surgical excision with free margins is the treatment of choice although close postoperative monitoring it’s
essential to avoid relapses
