Mucoepidermoid carcinoma of the mandible.

Mucoepidermoid carcinomas originating within the body of the mandible are uncommon tumors with histogenesis and treatment reviewed. The second youngest patient in the literature is reported with a tumor originating within the angle of the mandible. Treatment consisted of wide local excision, including composite resection of the mandible without evidence of recurrence at two years.

Congenital multiple fibromatosis (infantile myofibromatosis).

A female newborn had a rare case of congenital multiple fibromatosis, consisting of multiple fibrous lesions that histologically resemble myofibromas. Bony and soft-tissue lesions usually undergo spontaneous resolution, but excision may be required if vital structures are compromised as was the case in this patient. When the lesions involve the viscera in a generalized form of the disease, the result is often fatal.

Complications of the external (combination) rhinoplasty approach.

More rhinoplastic surgeons are using the external (combination) rhinoplasty approach for selected patients. Although several large series report few complications, the initial experience of newcomers may be different. A series of 26 external rhinoplasty approaches was examined, representing the initial experience of supervised residents. The most common complication was incising the anterior margin of the lower lateral cartilage at the juncture of the lateral and medial crura. To prevent this problem, it is recommended that the skin be elevated off the lower lateral cartilages from both a medial direction up over the domes and a lateral direction downward. To repair this complication, a figure-of-eight suture is used to reapproximate the incision.

Autologous fascia grafts in head and neck plastic surgery.

Using an experimental animal model, we studied the stability of the size (gross morphology) and structure (histomorphology) of the fascia autograft. Fascia from a rabbit's leg was grafted in the subcutaneous tissue of the ear and abdomen and also into the intra-abdominal cavity. The weight and size of the autograft were recorded during the study period. Our findings showed that the size of the autograft remained stable, but there was a substantial weight reduction. Microscopic examination of histopathologic sections disclosed that there was no inflammatory response to the fascia. It also appeared to maintain its histomorphologic structure. Clinical trials with patients receiving facial plastic surgery are also reported. We believe a fascia autograft can be used to augment facial areas. We base this conclusion on the findings from previous reports, our animal experiment, and clinical trials.

Nasal polyposis with stromal atypia. Review of follow-up study of 14 cases.

The clinical, microscopical, and gross pathological features of 14 cases of intranasal and paranasal sinus polyposis with unusual stromal cell atypia are described. In gross appearance, the lesions were polypoid, translucent masses, similar to the usual nasal polyp. Although clinically the lesions were indicative of allergic and inflammatory nasal polyposis, microscopical examination showed numerous large, often pleomorphic histiocytes or facultative fibroblasts that were suggestive or sarcomatous, malignant degeneration. Diagnoses by the original contributing pathologists included embryonal rhabdomyosarcoma, stromal neoplasia, and juvenile masopharyngeal angiofibroma. Follow-up data showed no evidence of neoplasia, despite the remarkable cytological changes found in the stroma. The stromal atypia most likely represents a reactive phenomenon secondary to inflammation.
