aspiration blood
Introduction
Introduction Nasal cavity, especially in the posterior nasal passages, inflammation of the nasopharynx, nasopharyngeal carcinoma, etc., all show up as sucking blood. The sucking blood stasis is dry in the weather, and local infection is the most common. Nasopharyngeal carcinoma is one of the most common malignant tumors in China. It often occurs in the pharyngeal crypt and the anterior anterior wall of the nasopharynx. The lesions may be in the form of nodular, ulceric, and submucosal infiltration. Most of them are Low-profile squamous cell carcinoma Others may be adenocarcinoma, undifferentiated cancer, and the like. Because the primary cancer breaks through the surface mucosa and blood stasis occurs, the nasal secretions often have bloodshot or blood clots when sucked back. It is more common after morning, which is one of the early symptoms.

1. Rearoscopy
Convenient and easy. The small nodules or granuloma-like bulges of the pharyngeal recess and the anterior wall of the nasopharynx can be seen, the surface is rough and uneven, and it is easy to bleed, sometimes showing submucosal bulge. When the early lesions are not typical, they may only show mucosal congestion, vascular engorgement or a full pharyngeal crypt, which needs to be taken seriously.
2. Fiber nasopharyngoscopy
It is conducive to the discovery of early microscopic lesions, especially for patients with strong pharyngeal reflex or difficult mouth opening. If suspicious lesions are found, biopsy should be performed in time.
Diagnosis
Differential diagnosis
Nasal cavity, especially in the posterior nasal passages, inflammation of the nasopharynx, nasopharyngeal carcinoma, etc., all show up as sucking blood. The sucking blood stasis is dry in the weather, and local infection is the most common. Therefore, the relevant examination means to assist the diagnosis. Find out the real cause of the disease.
