Facial nerve palsy as a result of squamous cell carcinoma of the skin.

Perineural invasion is increasingly recognized as a significant mode of tumor spread in squamous cell carcinoma (SCC) of the skin. Clinically, it is very difficult to diagnose perineural involvement in the majority of patients due to the lack of symptoms. The occasional propensity for perineural invasion from SCCs of the skin of the head and neck region is well documented and, although SCCs arising from actinically damaged skin reportedly have a low incidence of metastasis or deep invasion, failure to recognize this potential mode of spread could result in fatal consequences.

Perineural invasion of the facial nerve by a cutaneous squamous cell cancer: a case report.

We report a case of perineural invasion of the facial nerve by a cutaneous squamous cell carcinoma in a 59-year-old man who presented with a slowly progressive facial paralysis. We performed a distal facial nerve dissection and a simple mastoidectomy with facial recess exposure for resection to negative margins. We also performed a simultaneous facial reconstruction and reanimation procedure with excellent results. External-beam radiation completed the treatment regimen. In addition to describing this case, we review current concepts in diagnosis and therapy, as well as the historical background of malignant perineural invasion of the cranial nerves.

MR imaging in two cases of subacute denervation change in the muscles of facial expression.

SUMMARY: Denervation changes in muscle following damage to cranial and peripheral nerves can be observed on both CT and MR imaging studies. These findings are well described for cranial nerves (CN) V, X, XI, and XII. The CT findings of denervation atrophy due to CN VII dysfunction have been reported. We describe the MR imaging findings in two patients with perineural spread of tumor along CN VII. Both patients showed T2 prolongation and postcontrast enhancement in muscles of facial expression, suggestive of subacute denervation changes.

The numb cheek syndrome: a sign of infraorbital neuropathy.

Three patients with skin cancer had numbness isolated to one cheek, in the distribution of the infraorbital nerve. Hypesthesia also involved the medial and lateral upper incisors and canine teeth, and adjacent gingiva, sparing the more posterior teeth and gums. The molar and premolar teeth and gums are innervated by the posterior and middle superior alveolar nerves; because these structures were spared, the pathologic process was localized to the infraorbital foramen, and we could exclude involvement of the maxillary division more proximally. In two patients, cheek numbness heralded recurrent squamous cell carcinoma. Analogous anatomy at the mental foramen should help distinguish intracranial leptomeningeal from local mandibular lesions producing isolated numbness of the chin.

[Intraparotid facial neurilemmoma].

Neurilemmomas or schwannomas are known to arise from the sheath of peripheral nerves. Out of the cranial nerves, the eighth nerve is the most frequently involved. Neurilemmomas arising from the facial nerve are are, and they usually affect the intratemporal portion of the nerve. Its location in the intraparotid portion is very uncommon. The case of a patient having an intraparotid mass is shown. After surgery it was found to be a neurilemmoma of the facial nerve. These tumors manifest as an asymptomatic mass in the parotid gland. Most of the times, diagnosis is made postoperatively. It is necessary to remove all the tumor with the caution to preserve the original nerve.

Pulmonary metastasis from a basal-cell carcinoma of the retroauricular region.

Basal-cell carcinoma of the skin is a common facial neoplasm, usually regarded as benign. It is also called basalioma. Distant metastasis is very rare and may involve the brain, lung, and bones. We report a 74-year-old white male who was admitted to our hospital with cough and fever. Chest radiograph revealed an opacity of 2 x 1 cm in diameter in the upper lobe of the right lung. Bronchoscopy and thoracic fine-needle aspiration could not establish a diagnosis. Therefore the patient underwent right thoracotomy and wedge excision of the lesion. Histologic evaluation was consistent with pulmonary metastasis of a facial basal-cell carcinoma. The patient recovered uneventfully from surgery and is well 5 years after the operation. According to the English literature the median survival of patients with metastatic basal-cell carcinoma is 10 months. The clinical features, pathology, and treatment of this rare entity are discussed.

[Retrograde perineural extension of a metastatic recurrence of a frontal skin tumor].

Perineural metastatic spread of malignant tumours has been described for a long time, but has only recently been demonstrated by medical imaging. MRI, guided by the clinical findings, with fine sections on T1-weighted sequences without and with gadolinium, allows the diagnosis of this type of spread. The tumours most frequently responsible are squamous cell carcinomas and cylindromas. The trigeminal and facial nerves are the most frequently affected. Recognition of such lesions is essential in the initial staging of a malignant tumour of the face, as it alters the therapeutic strategy.

[Problems of lymphangioma of the parotid gland and adjacent tissues].

Two cases of caverno-cystic lymphangioma of parotid gland in children were described. The tumor removal required the discovery of extratemporal part of the facial nerve. In spite of the microsurgery technique the preservation of the thin nerve branch of the 5 months old child was impossible. The reconstruction of the nerve gave only the reinnervation++ of the upper lip. The myoplasty of the orbicular eye muscle by means of a part of the temporal nerve was performed and the rehabilitation procedure was successful. The great dynamic of lymphangioma speaks for an immediate surgery.
