Atypical Presentation of an Upper Lip Pleomorphic Adenoma: Case Report
Acta Stomatologica Croatica
The pleomorphic adenoma (PA) or mixed tumor is the most common neoplasm of the salivary glands, usually presenting with a non-specific clinical manifestation and a diverse histopathological pattern. The region of the lips is the second most common site for minor gland neoplasms. The aim of this paper is to report the case of a 39 year old caucasian woman presenting with a swelling on the right side of the upper lip combined with a history of trauma in the region of the upper right central incisor, eight years ago. The swelling was attributed to the periapical lesion of the upper right central incisor that was observed on the orthopantomography. Intraoperatively the surgeon came upon a nodule of firm consistency in the mucolabial fold. The histopathologic diagnosis of this lesion was benign mixed tumor of salivary gland. This report discusses the deviation in frequency of mixed salivary gland tumor between upper and lower lip, the clinical differential diagnosis, the histopathological pattern and the appropriate treatment.

Transient Delayed Facial Nerve Palsy After Inferior Alveolar Nerve Block Anesthesia
Tzermpos, Fotios H.
Facial nerve palsy, as a complication of an inferior alveolar nerve block anesthesia, is a rarely reported incident. Based on the time elapsed, from the moment of the injection to the onset of the symptoms, the paralysis could be either immediate or delayed. The purpose of this article is to report a case of delayed facial palsy as a result of inferior alveolar nerve block, which occurred 24 hours after the anesthetic administration and subsided in about 8 weeks. The pathogenesis, treatment, and results of an 8-week follow-up for a 20-year-old patient referred to a private maxillofacial clinic are presented and discussed. The patient's previous medical history was unremarkable. On clinical examination the patient exhibited generalized weakness of the left side of her face with a flat and expressionless appearance, and she was unable to close her left eye. One day before the onset of the symptoms, the patient had visited her dentist for a routine restorative procedure on the lower left first molar and an inferior alveolar block anesthesia was administered. The patient's medical history, clinical appearance, and complete examinations led to the diagnosis of delayed facial nerve palsy. Although neurologic occurrences are rare, dentists should keep in mind that certain dental procedures, such as inferior alveolar block anesthesia, could initiate facial nerve palsy. Attention should be paid during the administration of the anesthetic solution.
