Coughing up foul-smelling dry scabs

Introduction Due to the effects of diseases such as atrophic pharyngitis, patients may sometimes cough up a clinical symptom of odorous dryness. Atrophic pharyngitis (atrophic pharyngitis) is often secondary to atrophic rhinitis, the cause is unknown, the main pathological changes are pharyngeal glands and mucosal atrophy. At the beginning, the mucous gland is secreted and the secretion is thick. Following the inflammation of the submucosa, it gradually becomes mechanized and contracted, oppressing the mucous glands and blood vessels, impeding glandular secretion and nutrient supply, causing the mucosal layer and submucosa to shrink and become thinner. It is long and difficult to cure.

Cause

Secondary to atrophic rhinitis, the cause is unknown. The main pathological changes were pharyngeal glands and mucosal atrophy.

Differential diagnosis

Differential diagnosis of cough with odorous dryness:

1. Cough out brown sputum: The main symptoms of acute allergic bronchopulmonary aspergillosis are wheezing (96%), hemoptysis (85%), pyogenic sputum (80%), fever (68%), chest pain (55%) ) and cough up brown sputum (54%). The majority of hemoptysis is blood stasis, but 4% of patients have a large amount of hemoptysis.

2, cough chocolate color: sputum is the mucus secreted by the mucous membranes of the respiratory tract (bronchial, tracheal, larynx, nasal). Under normal circumstances, the mucous membrane of the respiratory tract secretes a small amount of mucus to maintain the moisturization of the respiratory tract. The dipping solution can also act as a barrier. It can stick to germs and dust, foreign matter, etc. that invade the respiratory tract. Because there is a large amount of "lysozyme" in the mucus, it can kill the bacteria. Reddish-brown or chocolate-colored sputum, seen in the amebic disease of the lung caused by the amoebic abscess that penetrates into the lungs.
