What are the early symptoms and warning signs of nasal hemangioma?

Nasal hemangioma's early symptoms and warning signs generally include localized nasal swelling, recurrent nosebleeds, unilateral nasal obstruction, a sensation of foreign body in the nasal cavity, and abnormal nasal discharge. The details are as follows:

1. Localized nasal swelling: In the early stage, there may be slight protrusion on the inner wall of the nasal cavity or the nasal septum, often appearing dark red or purplish-red in color, with soft texture and slight elasticity upon pressure. Smaller swellings may only be detected via nasal endoscopy and are usually not obvious to the naked eye during daily observation.

2. Recurrent nosebleeds: This is a relatively common early symptom. The bleeding volume is typically small, often presenting as blood-streaked mucus or minor dripping. It frequently occurs after nose-blowing or nose-picking. The frequency varies—episodes may occur occasionally or recur within a short period. Bleeding is usually easy to control, generally stopping after several minutes of gentle pressure.

3. Unilateral nasal obstruction: If the hemangioma develops in one side of the nasal cavity, it can occupy space and cause mild one-sided nasal blockage in the early stage. The obstruction is usually mild and more noticeable at night or upon waking in the morning, possibly improving slightly with physical activity. As the lesion grows, the nasal obstruction gradually worsens and becomes persistent.

4. Sensation of a foreign body in the nasal cavity: Patients may frequently feel that something is stuck inside their nose, accompanied by mild itching or discomfort, prompting repeated nose-blowing or touching the nose. This sensation is typically localized to the side where the hemangioma is growing. There is usually no significant pain and it may be mistaken for dryness or mild inflammation of the nasal cavity.

5. Abnormal nasal discharge: In early stages, patients may experience increased nasal secretions, sometimes mixed with small streaks of blood or mucus. Some individuals may notice slightly pink-tinged, viscous discharge without a foul odor. If mild infection occurs concurrently, the discharge may become slightly purulent, although infectious symptoms are typically not prominent.

Upon noticing any of the above symptoms, avoid forceful nose-blowing or picking to prevent irritation and potential bleeding. Seek timely evaluation from an otolaryngologist (ear, nose, and throat specialist) for definitive diagnosis using nasal endoscopy and other appropriate examinations.
