When it comes to understanding issues related to microvascular structures in the throat, it’s important to recognize that the throat contains a complex network of blood vessels, including microvessels. These vessels can sometimes become more prominent due to various factors, including inflammation, irritation, or even benign vascular malformations.
From your description, it sounds like you are observing a microvascular structure that becomes more visible when you exert pressure or strain your throat. The appearance of a dark spot or a "black" area could be due to several reasons:
1. Normal Variants: It is not uncommon for individuals to have small, benign vascular structures that can become more pronounced with certain movements or actions, such as swallowing or speaking. These can be completely normal and may not indicate any underlying pathology.

2. Vascular Malformations: In some cases, what you are seeing could be a small vascular malformation, such as a venous lake or a small hemangioma. These are usually benign and may not require treatment unless they cause discomfort or other symptoms.

3. Inflammation or Irritation: If you have recently experienced any throat irritation, such as from allergies, infections, or even excessive coughing, this could lead to localized inflammation that makes blood vessels more prominent.
4. Potential Concerns: While many vascular changes in the throat are benign, it is essential to monitor any changes. If the area becomes painful, changes in color, or if you experience other symptoms such as difficulty swallowing, persistent sore throat, or changes in voice, it would be prudent to consult a healthcare professional.

5. Diagnosis and Evaluation: If you are concerned about the appearance of this microvascular structure, a visit to an Ear, Nose, and Throat (ENT) specialist would be beneficial. They can perform a thorough examination, possibly using a laryngoscope, to visualize the area more clearly and determine if any further investigation or treatment is necessary.

In summary, while the appearance of a dark microvascular structure in the throat can be concerning, it is often benign, especially if it only appears under certain conditions. However, it is always best to err on the side of caution and seek professional advice if you have any doubts or if the situation changes. Regular check-ups and being aware of your body’s signals are key to maintaining throat health.
