Merkel cell carcinoma.
Merkel cell carcinoma is an unusual primary cutaneous tumor with an aggressive biologic nature. Following surgical treatment, 40% of patients have local recurrences develop, 55% have regional lymph node metastases develop, and 49% have distant metastases develop. We have treated four patients with Merkel cell carcinoma; only one of the four patients was alive and well after 2 years. Two patients died of metastatic disease, one at 11 months following initial treatment and one at 39 months. The fourth patient had a rapid recurrence following initial treatment and is currently in remission following chemotherapy for regional metastases. Recent reports indicate that chemotherapy may be helpful in treating patients with recurrent or metastatic Merkel cell carcinoma.

Cancer of the scalp.
Carcinomas on the scalp have a tendency to recur following traditional treatment. Their management is often difficult because of the extent of the tumor and the unique anatomy of the area. In order to maximize cure rates for complicated carcinomas, Mohs micrographic surgeons and other surgical specialists have formed interdisciplinary treatment teams. Resection of bone, parotid/facial nerve dissection, and neck dissection are often necessary. Interdisciplinary cooperation in the treatment of skin cancer leads to maximal utilization of expertise and is a major advance in cancer treatment.

Modified neck dissection for metastatic testicular carcinoma.
Carcinoma of the testicle is a unique clinicopathologic entity in that an optimistic attitude toward cure can be entertained even in the presence of distant metastasis. Chemotherapy, followed by an aggressive surgical resection of residual disease, can result in eradication of this neoplasm. This tumor is capable of being monitored by the use of serum markers, namely, human chorionic gonadotropin and alpha-fetoprotein. After induction chemotherapy, the transition of elevated serum tumor markers to normal levels suggests that malignant disease has been eliminated or converted to teratoma. Elevated markers indicate persistent or recurrent carcinoma and mandate further chemotherapy. If normalization of tumor markers occurs, any residual mass in the abdomen, chest, or neck should be surgically resected. The otolaryngologist plays a role in the diagnosis and the resection of residual neck disease. Metastatic testicular carcinoma can present as a supraclavicular neck mass and must be considered in the differential diagnosis of a mass in this area. Large residual neck lesions are best removed through the exposure afforded by modified neck dissection.

Goldenhar syndrome. Associated with submandibular gland hyperplasia and hemihypoplasia of the mobile tongue.
We report of a case of Goldenhar syndrome with submandibular gland hyperplasia and hemihypoplasia of the mobile tongue. This association has not been noted in the literature. A vascular abnormality or hemorrhagic phenomenon occurring during embryogenesis have been proposed as an explanation for the spectrum of defects seen in this syndrome. Congenitae hearing loss, when it occurs in Goldenhar syndrome, is usually unilateral and conductive in nature; however, inner ear defects may be more common than previously recognized.

Congenital tracheoesophageal fistulas in adults.
Congenital tracheoesophageal fistula without esophageal atresia is commonly known as "H" type. This is an extremely rare anomaly in infants and accounts for approximately 1 1/2-4% of all congenital tracheoesophageal malformations. An anomaly should be described by its anatomical defect, not by a number or letter. There are five main anatomical categories with 85-95% being of the esophageal atresia and distal tracheoesophageal fistula type. About 1 1/2% are of the "H" type. Although today tracheoesophageal fistula is a well-recognized entity, a few of the "H" type have passed through the pediatric period without diagnosis. Those undetected fistulas have successfully masqueraded as chronic lung disease of unknown etiology. Congenital "H" type tracheoesophageal fistulas assume an oblique orientation with the growth of the host to adulthood. This helps to explain the difficulty in diagnosis plus the ability of the host to survive to adult life. Treatment is surgical, consisting of simple ligation via cervical or thoracic approach depending upon location. The 12 previously reported cases in the English literature are reviewed, and a 13th case has been added.

Neck dissection: radical or conservative.
Four hundred and forty-five neck dissections for epidermoid carcinoma over a 10-year period are reviewed as to local recurrence of neck disease. Three hundred and forty-seven dissections were radical en bloc procedures and in 98 a modified conservative technique was utilized. Cervical lymph node classification was applied and a comparison made of the two techniques. A review of the anatomy of cervical fascias and the technique of conservative neck dissection is given. Evaluation of this series of cases indicate that the control of local disease in the neck in the N0 and N1 groups is is accomplished as well with conservative dissection as with radical neck dissection. The number of conservative neck dissections for N2 disease was too limited for accurate comparison. There were no conservative neck dissections done for N3 disease. We suggest that conservative neck dissection be utilized for subclinical and N1 disease and that the classic en bloc dissection be reserved for N2 and N3 situations.
