Primary reconstruction of congenital facial lesion defects with tissue expansion.

BACKGROUND: Congenital facial lesions may require surgical intervention to correct deformity or to decrease the potential for malignant degeneration. OBJECTIVE: Hemangiomata and melanocytic and sebaceous nevi are among the most common congenital facial defects. The techniques and outcome of serial tissue expansion in the management of facial lesions were evaluated. METHODS: Seven pediatric patients had congenital facial defects treated with tissue expansion and subsequent excision and reconstruction. RESULTS: All patients had a satisfactory outcome. Complications are reviewed, and in this patient population were minor. CONCLUSIONS: Tissue expansion has a role in surgical management of congenital facial lesions. Staged excision, skin grafting and nonintervention are also options which must be individualized to the case at hand.

Parameningeal rhabdomyosarcoma.

The records of 27 patients with rhabdomyosarcoma involving the parameningeal area (nasopharynx, paranasal sinus, and middle ear) treated from 1961 to 1976 were reviewed. Due to the location of the primary tumor, radiation and chemotherapy were used but surgery was limited to simple biopsy. In the literature, spread of tumor from these primary sites to the meninges has been as high as 26-35%. In this series, meningeal disease developed in only 2 of the 27 patients (7%).

Anatomic considerations of the medial cuts in the subtotal temporal bone resection.

Eighteen temporal bones, 20 sets of polytomograms, and two sets of histologically sectioned temporal bones were studied and the literature was reviewed in order to describe the evolution and anatomic detail of the medial limits of the subtotal temporal bone resection used when malignant neoplasia has invaded the middle ear. An en bloc resection requires incisions medial to the pneumatized spaces involved. The anatomy of the lines of resection through the glenoid fossa, medial to the lateral wall of the carotid canal, through the cochlea, internal auditory canal, and jugular bulb, and just lateral to cranial nerves IX, X, and XI was described in detail. Regardless of the techniques employed, or the feasibility of the task, the concept of en bloc resection must conform to the anatomy of the region.

Pituitary carcinoma occurring as middle ear tumor.

Pituitary gland tumors are most commonly adenomas of the glandular tissue. They are benign, slow-growing tumors confined to the pituitary fossa region. Pituitary tumors that become aggressive, involving contiguous bony structures and brain, as well as metastasizing out of the confines of the skull, are referred to as pituitary carcinomas. This case of pituitary carcinoma is the first reported in the literature occurring as a middle ear tumor. The literature documents many cases of pituitary carcinoma. The history and medical treatment of this case are presented.

Aggressive papillary tumour of the nasopharynx followed by an aggressive papillary tumour of the middle ear. A multiple site tumour?

We report the case of a 72-year-old male presenting with a papillary adenocarcinoma of the middle ear. He had had a similar tumour excised from the ipsilateral nasopharynx seven years previously with no evidence of local recurrence. We conclude that this middle ear lesion possibly represents a second tumour. No record of such a case has been reported previously in the literature. We discuss presentation and management and highlight the need for close follow-up of these patients.

Squamous cell carcinoma of the external auditory canal: an evaluation of a staging system.

OBJECTIVE: The study was conducted to review a staging system proposed by the University of Pittsburgh for temporal bone cancer and to evaluate survival status according to stage, treatment, and certain prognostic factors. STUDY DESIGN: The study was a retrospective case review. SETTING: The study was conducted at a tertiary care medical center and specialty hospital. PATIENTS: Thirty-two patients with primary squamous cell carcinoma of the external auditory canal were studied. INTERVENTION: All patients underwent surgery of the temporal bone. Radiotherapy was given depending on tumor stage and histopathologic findings. MAIN OUTCOME MEASURES: The 2-year survival rates of patients undergoing surgical resection with or without adjuvant radiotherapy. RESULTS: The 2-year survival rates for primary squamous cell carcinoma of the temporal bone were as follows: T1 lesions 100%, T2 80%, T3 50%, and T4 7%. Survival for T3 tumors was 75% with postoperative radiotherapy, compared with 0% with surgery alone. CONCLUSIONS: The 2-year survival data directly correlated with the staging system. The use of adjuvant radiotherapy increased survival rate in patients with a T3 lesion.

[Rare cases of neurofibroina in the head and neck].

Four cases of neurofibroma rare localized in parapharyngeal space and throat, in external ear and larynx are described. Three of them were isolated tumors and in one case--tumors in external ears developed in course of general Recklinghausen disease. Two cases of neurofibroma in parapharyngeal space had different clinical, CT and microscopic picture. In one case tumor protruded the throat obturating its oral part with osseous elements in its microscopic structure which caused characteristic CT picture. This one was excised through median mandibulotomy with good anatomical and functional result. The second case of parapharyngeal neurofibroma adherent to the superior cervical vertebra and only slightly dislocated the postero-lateral wall of the throat was excised through external cervical approach.

Wedge excision of lips and ears.

The wedge resection of malignant lesions on exposed parts of the lip and ear is a straightforward procedure. The keys to success include knowing the anatomy of these structures, careful marking of lines of incision, stopping bleeding and the meticulous realignment of skin surfaces.

[Skin metastasis in external ear canal of bladder carcinoma].

A case of vesical carcinoma skin metastasis in the external ear is presented. Apart from its uncommonness, cutaneous dissemination of a vesical carcinoma implies a poor prognosis since it is indicative of metastasis spreading to other sites, death occurring in nearly all cases within three months of diagnosis.

[Malignant eccrine poroma. Apropos of 2 facial sites].

The authors report 2 cases of malignant eccrine poroma (M.E.P.) located on the face: one on the auricle which was treated by triangular shape resection, the other on the nasal tip which underwent a reconstruction with a Converse scalping flap after large surgical resection removed underlying skin and cartilages. A study reviewing the main features of M.E.P. is presented on the basis of these clinical cases. M.E.P. are skin appendage tumors originating from the intra epithelial portion of the eccrine sweat duct. Such denominations as malignant hidroancanthoma, eccrine porocarcinoma, poroepithelioma, correspond to the same tumor. They are very rare: 73 cases have been reported in the world literature with only 12 located on the face; the main localisations involve the lower extremities, but the palmo plantar areas are involved more frequently in benign tumors. Elderly people over 60 are concerned in almost all cases. Many of the patients have noticed a lesion for years before a diagnosis was made suggesting one of the etiopathogenic theories that M.E.P. may result from malignant transformation of a benign eccrine poroma. Their clinical appearance is non specific nevertheless their malignant nature is suspected and misdiagnosis with basal cell carcinoma is frequent. Microscopic findings demonstrate the diagnosis by showing the association of malignant features with eccrine poroma. These tumours invade both by superficial spead and by deep extension towards dermal and hypodermal structures. Their prognosis is marked by the rapid development, in approximately on half of cases, of cutaneous, lymp node and visceral metastases. Clinical and histological examination have no prognostic value exception the case of deep invasion.(ABSTRACT TRUNCATED AT 250 WORDS)

[Late diagnosis of dysphonia].

The authors report on an observation of left-hand recurrent palarysis revealed by a sudden onset of dysphonia. The negative endoscopic findings led to a diagnosis of idiopathic recurrent paralysis. The biopsy of a right-hand sub-costsal subcutaneous tumefaction appeared three months later, leading to the diagnosis of mediastinal and hepatic metastasis following an epidermoid carcinoma of the right auricular pavilion, operated upon 5 years earlier.
