Respiratory obstruction caused by a multicentric granular cell tumor of the laryngotracheobronchial tree.

An unusual case of acute respiratory obstruction caused by multicentric granular cell tumors of the laryngotracheobronchial tree is presented. The patient also had granular cell tumors in the tongue, vulva, and chest wall. Multiplicity of the lesions in the left lung and recurrent episodes of intercurrent pulmonary infections necessitated left pneumonectomy. The extreme rarity of such a clinical circumstance is illustrated by a review of the literature. Salient clinical and pathological features of the tumor are briefly discussed.

Late effects in children treated with radiation therapy for Wilms' tumor.

PURPOSE: To determine the frequency and types of late effects in children receiving radiation therapy (RT) for Wilms' tumor. MATERIALS AND METHODS: From 1968 to 1994, 55 children received megavoltage RT at our institution as part of treatment for Wilms' tumor. A total of 42 (76.4%) have survived and have a minimum follow-up of 5 years. There were 25 female and 17 male patients with a median age at diagnosis of 48 months (range, 7-126 months). There were 12 Stage I, eight Stage II, 15 Stage III, six Stage IV, and one Stage V patient. RT was delivered to the hemiabdomen in 36 and whole abdomen in six patients. RT dose was 1000-1200 cGy (Group A) in 12, 1201-2399 cGy (Group B) in 11, and 2400-4000 cGy (Group C) in 19. Whole-lung RT was delivered to 13 patients either at diagnosis or pulmonary relapse. All patients received chemotherapy; the most common agents were actinomycin-D/vincristine/adriamycin in 13 and actinomycin-D/vincristine in 18. Median follow-up was 181 months (range, 60-306 months). RESULTS: Of 42 patients, 13 (31.0%) did not have late effects of treatment. The number of patients who developed muscular hypoplasia, limb length inequality, kyphosis, and iliac wing hypoplasia were seven (16.7%), five (11.9%), three (7.1%), and three (7.1%), respectively. Scoliosis was seen in 18 (42.9%) with only one patient requiring orthopedic intervention. Median time to development of scoliosis was 102 months, with a range of 16-146 months. The actuarial incidence of scoliosis at 5, 10, and 15 years after RT was 4.8 +/- 3.3%, 51.8 +/- 9.0%, and 56.7 +/- 9.3%, respectively. Only one of 12 Group A patients developed scoliosis. The 10- and 15-year actuarial incidences of scoliosis for Group A and B patients were 37.7 +/- 12.4% and 37.7 +/- 12.4%, whereas for Group C patients the incidences were 65.8 +/- 12.0% and 74.4 +/- 11. 7% (p = 0.03, log rank test). The actuarial incidence of bowel obstruction at 5, 10, and 15 years was 9.5 +/- 4.5%, 13.0 +/- 5.6%, and 17.0 +/- 6.5%. Of 23 patients, five irradiated within 10 days of surgery and one of 19 irradiated after 10 days developed bowel obstruction (p = 0.09, log rank test). Three patients developed hypertension with normal blood urea nitrogen (BUN) and creatinine levels; another patient had chronic renal insufficiency in a nonirradiated kidney. One patient developed diffuse interstitial pneumonitis. Of the 19 female patients who have reached puberty, three have given birth, and 15 have regular and one has irregular menstrual periods. Four patients developed benign neoplasms; three were in the RT field (two osteochondroma, one lipoma) and one outside (cervical intraepithelial neoplasia II). There were three second malignancies (chronic myelogenous leukemia at 9 years, osteosarcoma at 11 years, and breast cancer at 25 years after initial diagnosis of nephroblastoma); both solid malignancies occurred in the RT field. CONCLUSIONS: Late effects of therapy were seen in more than two thirds of children treated for Wilms' tumor. Children treated with lower doses (<2400 cGy) had a lower incidence of scoliosis compared with those who received more than 2400 cGy. There is also a suggestion that the incidence is lower in patients who received 1000-1200 cGy. Severe physical and functional deformity from RT was uncommon.

Case report: Myxoma of the temporalis muscle.

Intramuscular myxomas of the head and neck are rare entities. Primarily found in the myocardium, these lesions also affect the bones and soft tissues. We present a case of an intramuscular myxoma of the temporalis muscle. After reviewing the literature, this case constitutes, to our knowledge, the second reported occurrence of a myxoma in this specific location. The patient was treated for this condition with an excisional biopsy after fine needle aspiration revealed a benign process. No recurrence was seen 18 months after the excision.

Granular cell myoblastoma in the parotid gland.

Granular cell myoblastomas develop most commonly in the head and neck region, but their occurrence in the salivary glands has been reported in only one case, in the submaxillary gland. The authors report a case of granular cell myoblastoma in a previously undescribed localization, the parotid gland.
