Angiocentric lymphoma involving the temporal bone in a child.

Involvement of the temporal bone in patients with malignant lymphomas is very rare. Most of the reported cases have been clinically asymptomatic and were diagnosed only by post-mortem examinations. We present a nasal, paranasal, nasopharyngeal lymphoma that occurred in a 12-year-old child and also involved the temporal bone. Clinical presentation began with bilateral chronic otitis media. Histopathologically, tumor was found to be an angiocentric lymphoma of B-cell origin. Association with Epstein-Barr virus could not be demonstrated. Despite combination chemotherapy (with cyclophosphamide, vincristine, doksorubicine, prednisolone, L-asparaginase, cytosine arabinoside, metotraxate) and radiotherapy (to 40 Gy), disease progressed locally as well as to cervical lymph nodes and the lungs.

A comparison of procaine penicillin with sulbactam-ampicillin in the treatment of peritonsillar abscesses.

The clinical efficacy of procaine penicillin and sulbactam-ampicillin was compared in patients with peritonsillar abscesses after peroral abscess drainage. Forty-two patients were randomly assigned to receive either procaine penicillin or sulbactam-ampicillin intramuscularly on an outpatient basis. The mean time required for clinical symptoms (throat pain, dysphagia and fever) to resolve was compared. No statistically significant difference was found between the clinical recoveries of patients using either antibiotic (P > 0.05). The authors conclude that intramuscular procaine penicillin can be safely prescribed on an outpatient basis to most patients with peritonsillar abscess after incision and drainage. In contrast, a broader spectrum and more expensive antibiotic, such as sulbactam-ampicillin, should be reserved for non-responders.

Laryngeal pleomorphic rhabdomyosarcoma.

A case of an extremely unusual tumor of the larynx, pleomorphic rhabdomyosarcoma, is presented with a review of literature. This is the fifth case of this malignancy described in the larynx in the English language literature. A histopathological diagnosis was made with immunohistochemistry and electron microscopy. In contrast to other reported cases, the tumor in the present case had a very aggressive behavior. Despite radical surgery involving total laryngectomy and neck dissection followed by radiation therapy, the patient died of disease 8 months following treatment.

Postoperative hypertension after radical neck dissection.

Postoperative hypertension after radical neck dissection was detected in 20.2% of 109 neck dissections in our department between 1989 and 1993. It was probably caused by carotid sinus denervation and appeared after the vasodilation generated by anesthesia had subsided. If postoperative hypertension was encountered after the first operation, the risk of such hypertension after surgery on the contralateral side significantly increased.

Role of suprahyoid neck dissection in the treatment of squamous cell carcinoma of the lower lip.

Treatment of squamous cell carcinoma of the lip is primarily surgical. Unlike other oral lesions, lower lip cancers do not metastasize to lower cervical lymph nodes without invading submental and submandibular lymph nodes. This study presents 30 patients with N0 lower lip carcinoma who were treated by en bloc resection of the tumor with suprahyoid neck dissection. Occult metastasis was found in 4 patients (13%). Four patients, 3 of whom had no occult metastases, died of local or regional uncontrollable disease. Suprahyoid or modified radical neck dissection appears to be beneficial, even in small tumors of the lower lip, in detecting occult metastases.

Basaloid squamous cell carcinoma of the larynx.

Basaloid squamous cell carcinoma is a variant of squamous cell carcinoma that was first described in 1986. In the English-language literature, only 26 cases of this infrequent histopathological entity have been reported in the larynx. Tumors have an aggressive biological behavior, justifying combined surgical treatment with radiotherapy. Two new cases are presented and the literature reviewed.

Effect of blood transfusion on tumor recurrence and postoperative pharyngocutaneous fistula formation in patients subjected to total laryngectomy.

Some surgical oncologists and otolaryngologists have reported that transfusion-induced immunosuppression may increase the incidence of recurrence and infectious complications in patients subjected to head and neck surgery for carcinoma. The relationship between intra-operative blood transfusion and postoperative pharyngocutaneous fistula formation and/or tumor recurrence is controversial. In a retrospective study of 110 total laryngectomized patients, we found no statistically significant differences between the transfused and nontransfused groups in terms of tumor recurrence and fistula formation.

Early oral feeding after total laryngectomy.

Following total laryngectomy, 110 patients were orally fed on the first/second postoperative day without using a nasogastric (NG) tube. Pharyngo-cutaneous fistula was observed in 23 patients (21%) only nine of which (8%) needed surgical intervention to close the fistula. Early postoperative oral feeding of laryngectomized patients does not increase the fistula rate but decreases postoperative hospitalization time and eliminates the disadvantages of the NG tube.

Tracheobronchopathia osteochondroplastica: a case report and a review of the literature.

Tracheobronchopathia osteochondroplastica is characterized by osseocartilaginous submucosal nodules projecting into the lumen of the larynx, trachea, and bronchi. Its etiology is unknown. Most cases are asymptomatic and frequently diagnosed incidentally during intubation or endoscopy. The diagnosis is made on the basis of endoscopy, CT scan, and histopathology. Fragments of adipose tissue, deposits of calcification and ossification often with foci of bone marrow and active hemopoiesis are present in the submucosa. Surgical treatment is indicated for airway obstruction and recurrent infections.

Proliferating cell nuclear antigen immunoreactivity and the presence of P53 mutation in basaloid squamous cell carcinoma of the larynx.

Basaloid squamous cell carcinoma (BSCC) is an aggressive variant of squamous cell carcinoma (SCC) that was first described in 1986. In the English literature, only 28 cases of this histopathological entity have been reported in the larynx. Proliferative features of this infrequent tumor were investigated by proliferating cell nuclear antigen immunoreactivity, and the presence of P53 mutation was also investigated in a series of 4 cases. BSCC was found to share similar features with regular SCC in terms of its proliferation rate and P53 mutation positivity, as well as biological behavior and clinical outcome.
