Review Case Reports
[Asthma or laryngeal amyloidosis? A report of a case and literature review].
The laryngeal amyloidosis is an uncommon disease accounting for 1% of all benign lesions of larynx. The commonest symptom is the dysphonia, sometimes accompanied by stridor, laryngeal globus sensation, dysphagia and, in rare occasions, cough, dyspnea and hemoptysis, specially when the tracheobronchial tree is also affected. This paper describes the case of a 30-year-old female patient, whose main symptoms were progressive dysphonia and dyspnea, admitted at allergy service to rule out asthma. ⋯ Biopsies of ventricular band, vocal cord and arytenoid stained with positive Congo red for amyloid tissue, established the laryngeal amyloidosis diagnosis. The complementary studies to rule out amyloid tissue in the remaining tracheobronchial tree were negative. Dyspnea had characteristics of laryngeal origin, caused by a pulmonary ventilation disorder provoked by the difficult arrival of air to alveoli, which caused the decreased partial pressure of oxygen and CO2.

Allergic rhinitis (AR) is rarely found in isolation and needs to be considered in the context of systemic allergic disease associated with numerous comorbid disorders, including asthma, chronic middle ear effusions, sinusitis, and lymphoid hypertrophy with obstructive sleep apnea, disordered sleep, and consequent behavioral and educational effects. The coexistence of allergic rhinitis and asthma is complex. First, the diagnosis of asthma may be confused by symptoms of cough caused by rhinitis and postnasal drip. ⋯ Prospective cohort studies are required to assess the disease burden caused by allergic rhinitis in childhood, its consequences due to delay in diagnosis and treatment, and to further assess the potential educational impairment that may result. Because allergic rhinitis is part of a systemic disease process, its diagnosis and management require a coordinated approach by the specialist in allergy-immunology-rhinology rather than a fragmented, organ based approach. There are other clinical presentations such as recurrent infections of the upper respiratory tract, as well as pharyngeal and laryngeal disorders.
