Twenty-seven patients with recurrent pleomorphic adenomas of the parotid gland were seen. This study confirms that superficial parotidectomy with identification and dissection of the facial nerve greatly decreases the incidence of recurrent benign pleomorphic adenoma, and, in the small number that recur, are easier to cure. All lumps in the parotid area should be approached in the same manner, with the surgeon prepared to isolate the facial nerve and perform superficial parotidectomy. This technique is successful because it avoids dissection near the tumor capsule, which is the major cause of recurrence. The procedure recommended for treatment of patients to remove the first recurrent tumor is total parotidectomy and excision of the previous scar. This vigorous approach is dictated by the increasing difficulty of removing further recurrent tumors. Only 67% of patients with recurrent tumors ultimately achieve a tumor-free status. Experienced surgeons can preserve the facial nerve even after multiple operations.

\s=b\Recurrent aphthous stomatitis (RAS) is characterized by necrotizing ulcers of the oral mucosa that persist, remit, and recur for variable periods of time. Despite the benign nature of the disease, persistent pain and ulceration may disable patients from performing their daily activities. We describe three patients with long-standing active RAS treated with oral colchicine. All patients experienced a marked decrease in symptoms and a remission of the disease. Recurrences, however, occurred within three days of discontinuation of the therapy. In one patient, colchicine therapy was discontinued because of persistent diarrhea. In another, a second remission was more difficult to achieve on the same regimen. The literature on the subject is reviewed, and the beneficial effects of colchicine therapy are discussed in relation to the immunopathogenesis of this disease. We conclude that colchicine therapy should be considered as an alternative in the treatment of the major or persistent form of RAS. (Arch Otolaryngol Head Neck Surg 1988;114:671-675) Recurrent aphthous stomatitis (RAS) is the most common form of nontraumatic oral mucosal ulcér¬ ation, with a prevalence of 20% among the general population.1·2 The first ulcération appears before the age of 30 years in 60% to 85% of the patients, but the incidence decreases

Teratomas are germ cell tumours usually found in the young and are characteristically composed of tissue foreign to the place where they arise. Two teratomas of the middle ear were first described in 1866 and since then, and to the best of our knowledge, 19 additional cases have been reported in the literature under different terms such as hairy congenital polyps, epidermoid cysts, dermoid cysts, hamartoma, cutaneous teratoma and teratomas. The difficulty in classifying germ cell tumours may explain the different terminologies encountered in the literature. The authors describe a case of teratoma of the eustachian tube presenting as a mass in the middle and external ear of a 10-week-old girl. Using this case, a review of the literature is performed in light of the new classification of germ cell tumours proposed by the World Health Organization (WHO). It is of note that most of the teratomas that present in the middle ear arise from, or involve, the eustachian tube.
