[Aspergillosis of maxillary sinus: a case report]. / Aspergillosis de seno maxilar. A propósito de un caso.

A case of semi-invasive maxillary aspergillosis that presented with epiphora and responded well to surgical treatment is reported. Sixteen percent of cases of chronic sinusitis are produced by mycosis (particularly aspergillosis). The infection may be limited to the affected sinus (non-invasive forms) or may destroy the sinus wall, without tissue invasion (semi-invasive forms) or with tissue invasion (invasive forms). The diagnosis is mainly histological. Cultures present a high percentage of false positives and negatives. Treatment consists of surgical debridement of the sinus. Systemic amphotericin B is reserved for invasive aspergillosis (particularly fulminant cases).

[The study of the evolution of laryngeal premalignant lesions]. / Estudio evolutivo de lesiones premalignas laríngeas.

Hyperkeratosis of the laryngeal epithelium is considered a clinically premalignant lesion that develops into invasive carcinoma in about 7-20% of cases. We reviewed 125 cases of patients with laryngeal keratosis in biopsy obtained by direct laryngocopy over a 10-year period. The evolution of these lesions to malignancy was conditioned by age, the presence of atypias in the initial lesions, and smoking; smoking is a modifiable factor. Surgery is the treatment of choice, with periodic follow-up for three to five years. The literature was reviewed.

[Acute respiratory obstruction caused by laryngeal rheumatoid arthritis]. / Obstrucción respiratoria aguda por artritis reumatoide laríngea.

We present a case of acute upper airway obstruction due to cricoarytenoid arthritis in severe rheumatoid arthritis. Although laryngeal involvement is common in severe rheumatoid arthritis, the upper airway obstruction is a very rare complication. The endotracheal intubation may be very difficult in these patients, thus fiberotopic bronchoscopy may be useful. Surgery is the final treatment.
