[Primary lung tumors]. / Tumores broncopulmonares primarios.

Pulmonary neoplasia in children is usually due to methastatic disease because primary lung tumors are very unfrequent. Due to its' rarity they are usually not included in the differential diagnosis of lung masses, so treatment is delayed and prognosis is worsened. Herein, we show our experience in the management of five primary tumors of the lung or the airway: one tracheal, three bronchial, and another intraparenchymatous. We study the clinical behaviour, diagnostic work-up, treatment, histology, and follow-up. Despite its rarity, a diagnosis of pulmonary tumor should be considered in any child with respiratory symptoms that does not improve with standard therapy. An early and accurate diagnosis and an adequate treatment are crutial in the prognosis of these patients.

[Tracheal stenosis: individualized treatment]. / Estenosis traqueales: tratamiento individualizado.

INTRODUCTION: Stenosing airway disease is unfrequent in the pediatric age group and includes intraluminal obstructions, extrinsic compressions and malacias. OBJECTIVE: To show our experience in the treatment of congenital and acquired tracheal stenosis (CTS and ATS) and suprastomal tracheal collapse (STC). PATIENTS AND METHODS: Since 1990, 24 patients have been evaluated in our Unit: Ten CTS, 5 ATS and 9 STC. We have studied the following parameters: Sex, age at diagnosis, ethiology, type of lesion, associated anomalies, treatment, postoperative intubation, length of hospital stay, number of bronchoscopies, complications and follow-up. RESULTS: 14 girls and 10 boys are included in this survey. Age at diagnosis ranged from 3 days to 12 years and associated anomalies were present in 75% of cases. We have treated 22 of the 24 patients with the following procedures: Costal cartilage tracheoplasty (6 cases), slide tracheoplasty (2), resection and anastomosis (3), anterior cricoid suspension (8), dilation (2) and laser resection (1). We have achieved good results in 17 patients (77%), bad in 4 (18%) and fair in one. CONCLUSIONS: Due to the variety of stenotic lesions, we think that treatment should be tailored to each particular case and performed by a multidisciplinary pediatric team in order to achieve the best results.

[Treatment of congenital tracheal stenosis using a slide tracheoplasty]. / Tratamiento de una estenosis traqueal congénita mediante una traqueoplastia deslizada.

Congenital tracheal stenosis (CTS) is a rare malformation that usually require corrective surgery. Resection and tracheal anastomosis is the treatment of choice when the stenosis is short. However, such an approach is not usually viable when the CTS is long, given that anastomotic pressure would be too great. New surgical techniques have allowed this serious airway malformation to be corrected satisfactorily. We report the case of a three-year-old boy with a long CTS (51% of the length of the trachea) treated with a new reconstructive technique called slide tracheoplasty. Outcome was excellent.
