[Respiratory insufficiency as the first sign of mitochondrial disorders].

INTRODUCTION: In spite of the great variability in clinical signs in the mitochondrial disorders, reports of respiratory disorders in these conditions are purely anecdotal, and almost all occurred in patients with clinical data of the illness. We present a case in which respiratory insufficiency was the first sign of a mitochondrial disorder. CASE REPORT: A 74 year old patient, with no significant clinical history, had two episodes of severe acute respiratory insufficiency without cardiopulmonary causes to justify it. The patient was investigated for neuromuscular disorders and had a muscle biopsy compatible with mitochondrial myopathy. CONCLUSION: The occurrence of respiratory failure in patients with mitochondrial disorders is exceptional, is not related to the degree of deterioration of the respiratory function tests and is potentially reversible.

[Mucoepidermoid carcinoma of the nasal vestibulum].

Mucoepidermoid carcinoma is a malignant epithelial tumor, with a mucosecretor component that is exceptional in the upper airways. It seems to be a kind of immunity in this area to the development of this tumors. In the review of the literature we only have found three cases in the nasal cavity. We present the case of a 18th years old woman with a tumor in the right nostril for two months. Several biopsy were required to achieve its histopathological diagnosis as a high malignant mucoepidermoid carcinoma. Radical surgery over the tumor and metastasis was performed but the case has a bad prognosis. The prognosis of the mucoepidermoid carcinoma depends on the histological grade, the early diagnosis and the surgical treatment which has to be so radical as possible to obtain free tumors limits.

[Frontal osteoma apropos of a case].

We report a case of frontal sinus osteoma in a 66-year-old woman, with headache and deformation of the upper-inner orbit wall; it was satisfactorily solved by means of osteoplastic technique with the aid of surgical microscope. We emphasize the extrasinusal extension, and specially when the osteoma grows towards the orbit or the endocranium, in order to settle on the surgical technique.
