RESUMO
A 38-year-old woman presented with progressively increasing breathlessness, recurrent productive cough, and intermittent fever of 1 year duration. Examination revealed cutaneous eruptions on the dorsal aspects of the hands and on face. Histopathologic features of skin biopsy revealed acanthosis, hyperkeratosis with focal vacuolar alteration of the basal-cell layer, and perivascular inflammatory infiltrates in upper dermis. CT scan showed diffuse lung disease and pulmonary function tests showed severe restrictive lung disease. There was no muscular involvement clinically or on electromyography and magnetic resonance imaging. She was diagnosed as a case of amyopathic dermatomyositis with diffuse lung disease and managed with topical and systemic steroid and topical sunscreen with fairly good response.
RESUMO
Lower respiratory tract infection is one of the common causes of morbidity in India which is occasionally undiagnosed. In this regard tracheobronchomegaly is one of those conditions which masquerade as chronic bronchitis and bronchiectasis and are usually undiagnosed. It is a well-defined clinical and radiologic entity characterized by marked dilatation of the trachea and the central bronchi and is frequently associated with recurrent lower respiratory tract infection. Tracheobronchomegaly has been described by a variety of names, including Mounier-Kuhn syndrome, tracheal diverticulosis, tracheobronchiectasis, tracheocele, tracheomalacia, and tracheobronchopathia malacia.
