Castleman's disease restricted to the infratemporal fossa.

Giant lymph node hyperplasia (Castleman's disease) is usually reported as a solitary mediastinal tumour, although involvement of other anatomical sites and a multicentric form have been reported. We describe a rare case of Castleman's disease due to its localisation (the left infratemporal fossa) and histology (plasma-cell variant). A brief review of the main clinico-histological characteristics of Castleman's disease is also presented.

Extended supraglottic laryngectomy for primary base of tongue carcinomas.

A retrospective review of 56 patients with a primary base of tongue carcinoma was undertaken to determine the value of supraglottic laryngectomy. All the patients had a supraglottic laryngectomy and a total of 77 neck dissections. Forty-three (76.8%) patients received post-operative radiotherapy. The incidence of local recurrence was 23.2%, neck relapse being seen in 16.1% of patients. The 3 year survival was 47%. The overall survival of the whole series and by stage was not improved by combined therapy compared with surgery alone.

Complications of supraglottic laryngectomy for carcinomas of the supraglottis and the base of the tongue.

The medical records of patients with either a supraglottic carcinoma (n = 193) or a base of tongue carcinoma (n = 56) who underwent a supraglottic laryngectomy were studied. Because of aspiration total laryngectomy was required in 9.8% and 21.4% of patients with supraglottic and base of tongue carcinomas, respectively, being related to locally advanced stage of disease in the base of tongue and to an age older than 65 years in the case of supraglottic carcinomas. The non-decannulation rates were 23.8% and 50% in supraglottic and base of tongue tumours respectively. Post-operative radiotherapy did not influence the decannulation rate, but advanced local disease and age did. Post-operative mortality in the first month after the operation was 2.6% in supraglottic tumours and 3.6% in base of tongue tumours.

Supraglottic laryngectomy with or without postoperative radiotherapy in supraglottic carcinomas.

A retrospective review of 193 previously untreated patients with primary supraglottic carcinoma was undertaken to ascertain the efficacy of postoperative radiotherapy. All the patients received a supraglottic laryngectomy, and patients received a total of 284 elective or therapeutic neck dissections. Ninety-four (48.7%) of the patients received postoperative radiotherapy. The incidence of local recurrence was 8.2% but the recurrence rate was unrelated to the use of postoperative radiotherapy. Neck recurrence was observed in 12.9% of patients, with no influence of postoperative radiotherapy in the dissected neck. The incidence of locoregional recurrences by stage in irradiated and nonirradiated patients did not reach significant difference. The 3-year survival was 74.3%. The overall survival of the whole series and by stage was not statistically altered in combined therapy compared to surgery.

Prognostic factors in paranasal sinus cancer.

PURPOSE: This study was designed to evaluate the influence of several different prognostic factors in determining both local recurrence rates and survival in patients treated for carcinoma of the paranasal sinuses. MATERIALS AND METHODS: A retrospective study of patients treated between January, 1975 and December, 1991 was undertaken. Hospital charts were reviewed collecting demographic, clinical, and radiographic findings, which were correlated with treatment and subsequent follow-up. RESULTS: Carcinoma of the paranasal sinuses was identified in 129 patients. This included 95 men and 34 women with an average of 59 years. The ethmoid sinus was primarily involved in 50 patients, the maxillary sinus and 49, the nasal sinus and 25, sphenoid sinus in three in the frontal sinus and two patients. Advanced stage (T3/T4) was diagnosed in 60% of patients at presentation. The most commonly encountered histologies were squamous-cell carcinoma and adenocarcinoma. The most accurate predictors of poor prognosis were advanced T stage and involvement of the anterior skill base. Involvement of the posterior wall of the maxillary sinus, infratemporal fossa, and erosion of the orbital wall was not associated with the worst prognosis. CONCLUSION: In spite of advances in imaging technique and surgical therapy, the primary cause of death is inability to control local disease. Diagnosis at an earlier stage is associated with improved outcome.

Malignant fibrous histiocytoma of the nasal cavity and paranasal sinuses.

Malignant fibrous histiocytomas are uncommon in the head and neck, the sinonasal tract being the most common location. This report describes 5 cases in this area: two in the nasal cavity, two in the maxillary sinus, and one in the frontal sinus. Four were primary cases and one was secondary to previous irradiation. All patients received surgical treatment, one of them with postoperative irradiation. All five patients experienced local recurrences and three also experienced distant metastases. Only one of these recurrences was successfully salvaged and the patient is alive and free of disease 3 years after resection. A summary of knowledge about the entity is reviewed.
