The "Pinocchio" nasal deformity--hemangioma vs. angiolipoma: esthetic correction and etiology.

The author presents the first reported case of a nasal angiolipoma presenting as "Pinocchio" nasal tip deformity. The two types of angiolipomas (infiltrating and non-infiltrating) are discussed as are two surgical approaches to this deformity. The author feels that the external rhinoplasty technique is an excellent way to approach this problem, especially in patients who are suffering severe emotional stress due to peer pressure.

Lethal midline granuloma with a novel T-cell phenotype as found in peripheral T-cell lymphoma.

Lethal midline granuloma (LMG), initially a clinical description, includes an uncommon group of disorders characterized by a relentless, destructive process involving the upper respiratory structures. Its etiology and pathogenesis are uncertain, probably varied, and the distinction between inflammatory and malignant processes is difficult despite extensive clinical and histopathologic evaluation. The need for new techniques for rapid diagnosis has important therapeutic implications. Using an extensive panel of T- and B-cell monoclonal antibodies the authors describe a patient with clinically and pathologically typical LMG demonstrating an "activated" T-cell phenotype with a "novel" pattern characteristic of peripheral T-cell lymphoma, strongly implying that some cases of LMG are more closely related to neoplastic T-cell lymphoproliferative disorders than to inflammatory conditions. Further studies using these immunotyping techniques may help clarify the pathogenesis of LMG, and may uncover specific diagnostic and prognostic phenotypic patterns.

Non-organic stridor in children.

A 4.75-year-old male presented with several episodes of expiratory stridor leading, on one occasion, to a respiratory arrest and intubation. A detailed evaluation emphasizing physiological and anatomical studies revealed no organic basis for the patient's upper airway obstruction. Emphasis is placed on one method found to be helpful in the differentiation of an organic versus a psychogenic type of respiratory disorder. Recognition of functional airway obstruction in children may prevent inappropriate therapy and allow proper psychiatric intervention.

Neonatal respiratory distress secondary to nasal fibrous histiocytoma.

A full term one-day-old neonate developed respiratory distress secondary to a right intranasal mass. After exploratory craniotomy revealed no intracranial lesions, the child was observed for 6 months. At that time he experienced severe apnea with cyanosis necessitating removal of the mass, which was diagnosed histologically as a fibrous histiocytoma. Seven year follow-up reveals no further problems. A discussion of fibrous histiocytoma of the nose and paranasal sinuses is briefly given.

The surgical treatment of skull-base tumors with intracranial extension.

As a discipline, skull-base surgery via the transtemporal route has matured since 1975. Previously considered unresectable, skull-base tumors with intracranial extension can now be successfully removed by means of modification of contemporary exposures with neurosurgical collaboration. Between September 1970 and February 1986, 126 skull-base tumors have been operated on by The Otology Group, P.C. Of these, 49 had intracranial extension. In this article, techniques for tumor removal and dural defect reconstruction are outlined. A single-staged procedure is advised. The advantages of and exceptions to this format are described. Techniques that will prevent postoperative cerebrospinal fluid leakage are highlighted. Results and complications of this surgical series are discussed, and team aspects of this surgery are emphasized.

Anesthetic considerations in facial plastic surgery: the surgeon's viewpoint.

In a cost-conscious medical and social community, the surgeon and anesthesiologist must work as a unit to attain the goal of patient comfort during elective, cosmetic procedures in a safe, cost-effective, medically acceptable manner. A close-working relationship between the surgeon and anesthesiologist is mandatory with each being cognizant and understanding of the special problems encountered by the colleague.

Sialadenitis in children.

Sialadenitis in children has been discussed. A literature review highlighting salient points in sialadenitis is presented. Classification of sialadenitis is discussed using the categories of several authors. An unusual case involving acute suppurative parotitis in a child is presented. The development of contralateral disease while treatment was in progress was unusual. In this case, association with mumps parotitis was strongly suspected despite previous immunization. Progression of disease with abscess formation is also unusual. Mumps virus parotitis has been rarely reported in association with acute suppurative parotitis. Immunization affords protection, but a definite failure rate exists. Based upon histologic examination, mumps parotitis would seem to be a predisposing factor for bacterial infection.

Mucosal melanoma of the head and neck.

Nine cases of primary malignant melanoma of the upper respiratory tract treated at the University Hospital over the past 10 years are presented. Of the 9 cases, 6 had primary lesions located in the nasal cavity with the remaining 3 presenting in the nasopharynx, hard palate, and larynx, respectively. The authors review presenting symptoms, diagnostic evaluation, current therapeutic modalities, and clinical course in these cases. Specific cases are discussed to emphasize items of clinical or therapeutic importance.

Retropharyngeal abscess--a ten-year experience.

The authors present an extensive review of current literature as well as their ten-year experience in management of patients with retropharyngeal abscesses. Emphasis is placed upon age, sex, type and duration of symptoms, bacteriology, methods of diagnosis, therapy, and complications. The authors' series reveals that retropharyngeal abscesses are found in adults, there is a wide spectrum of bacteriological organisms represented, and with appropriate antibiotic and surgical management the majority of patients survive without major residual sequelae.

Laryngeal carcinoma--or is it laryngeal blastomycosis.

A patient is described who was evaluated for persistent hoarseness. Although an initial diagnosis of squamous cell carcinoma of the larynx was made, review of the pathology slides revealed pseudoepitheliomatous hyperplasia, acanthosis, and what appeared to be a fungal infection. After a detailed work-up was initiated the patient was treated successfully with ketoconazole for a blastomycosis infection of the larynx. The literature relative to blastomycosis infections of the respiratory larynx is reviewed. The authors emphasize that patients who show evidence of acanthosis and pseudoepitheliomatous hyperplasia along with the diagnosis of squamous cell carcinoma should be suspected as having a potential fungal infection.

Infectious facial and nasal cutaneous necrosis: evaluation and diagnosis.

A review of the literature reveals that pyogenic gangrenosum (ecthyma gangrenosum) is fatal to most patients, especially infants. In this article, the authors review the differential diagnosis of facial necrosis, present two cases of infants who succumbed to the systemic manifestations of the disorder, and a third case of survival in an adult with concomitant systemic lupus erythematosus and pyogenic gangrenosum. Finally, a brief discussion of Pseudomonas gastroenteritis, Pseudomonas septicemia, and pseudomembranous enterocolitis is presented.
