Pathology of nasal polyps

2021-01-31 12:00 AM

Polyps grow slowly because they are getting bigger and bigger and fill up the nasal passages, causing the main symptom of a stuffy nose. Increased nasal congestion leads to nasal congestion.

A very common benign tumour can be merely in the nasal cavity, maybe in the facial sinuses or even in the nose, sinuses.

Nasal polyps are not actually tumours, but local degeneration of the nasal mucosa or sinuses, but mainly the stromal lining.

In terms of structure: the outside is the epithelial layer with the cylindrical, square or flat cell wall, the inside is the organization linked to the fibrous cells to form a loose layer, containing fluids or mucus, some lymphocytes, monocytes or eosinophils were also seen. Therefore, polyps are soft, smooth, transparent, pale pink in colour.

Reason

May be encountered due to many different reasons.

Due to inflammation: common in sinusitis, pus in the sinuses flows out through the middle nasal passages, causing the lining of this area to degenerate into polyps.

Due to allergies: common in nasal sinus allergies, however, polyps are not a lesion of allergies.

Also due to vasomotor disorders, endocrine disorders or created by the site.

Diagnose

Implementing the quadrants

Polyps grow slowly because they are getting bigger and bigger and fill up the nasal passages, causing the main symptom of a stuffy nose. Increased nasal congestion leads to nasal congestion. If polyps in both nasal passages are unable to breathe through the nose, lose their smell, speak with a closed nose.

A runny nose may occur during weather changes such as in allergy or thick, sinus pain caused by purulent sinusitis.

Nasal examination: the tumour is soft, smooth, shiny, light pink, usually in the middle of the nasal passages. If you see one or more masses in cluster wall filling the nostrils for a long time, emerging right at the back of the nose, spreading to the arch.

If due to sinusitis, the polyps around the polyps have a lot of pus, but the polyp's face never becomes necrotic. In addition to conventional polyps, you may experience the following:

Killian solitary polyps: only one polyp, can grow from the middle of the nose, curl or septum, the only symptom is nasal congestion.

Bleeding polyps: often have feet attached to the septum, the Kissel Bach vascular point area should cause bleeding easily.

Woakes disease: polyps present in the sinuses sieve on both sides, causing deformation of the nose main bone, widening the base of the nose, expanding the nasal-eye grooves, the two corners of the eye being further apart.

Differential diagnosis

Degenerative middle rhinorrhoea: caused by chronic sinusitis, a soft, smooth, pale pink mass, like polyps, has the same structure. When using the probe, the legs are stiff due to curly bones. When there are polyps in the nasal cavity, the whole middle nose is large degeneration, filling the nasal cavity, it is difficult to distinguish.

Nasopharyngeal fibroids: when polyps develop into the back of the nose into the arch or fibroids that develop into the nasal passages, it can be mistaken. Fibroids are common in puberty, white mass, opaque, not succulent, denser and easier to bleed.

Jaw cancer: also develops soft tumours like nasal polyps, but the tumour is not smooth, often has a rough, irregular density, or has superficial necrosis, very easy to bleed and has pus and bloody smell.

Treatment

Removing polyps in the nose by endoscopy does not cause bleeding, but if leftover, it will quickly recur.

If there is sinusitis, need to perform sinus opening to remove the lesions at the same time, remove polyps.
