A schwannoma is a tumor of the nervous system that develops in certain glial cells (non-excitable cells of the nervous system).

These cells create an insulating sheath (myelin) around neurons to facilitate the transmission of nerve impulses. They can develop into tumors that are usually benign.

A schwannoma can occur in any of the thoracic nerves. It can be treated with excision.

Mediastinal diseases

The mediastinum is the central part of the rib cage, located between the two lungs. It is divided into three sections: the posterior, middle and anterior mediastinum. It includes the heart, great vessels, esophagus and trachea, as well as the thymus.

Splanchnic pain

Splanchnic pain is pain associated with each of the sympathetic nerves that pass through the organs. It can occur with inflammation, tumors or polycystic diseases.

Surgery involves a splanchnicectomy (nerve cutting) that is sometimes combined with an excision (tumor removal).


Hyperhidrosis (excessive sweating of the body) affects about 3% of the population. It typically affects the hands (palmar hyperhidrosis), feet (plantar hyperhidrosis), armpits (axillary hyperhidrosis) and face. This condition most often begins in puberty and causes discomfort that is at times similar to a disability. People affected by this condition feel powerless and often ashamed. 

Thyroid nodules

Thyroid nodules are very common growths in the thyroid gland. They primarily affect women and occur more often as you get older. If you performed an ultrasound on every woman over 50, half of them would have a thyroid nodule!

Though the cause is unknown, nodules are often made up of thyroid cells, but can also contain fluid. Types of nodules include harmless micronodules (less than one centimeter), cysts (fluid-filled nodules), inflammatory nodules seen in thyroiditis, thyroid adenomas (benign tumors), and cancerous nodules.

Diseases of the thymus

The thymus is a gland located in front of the trachea. Its primary role is during growth when it provides the body with immune cells. It subsequently has no function and decreases in volume until disappearing almost completely in adulthood.

Myasthenia, a disease associated with the thymus, is a neurological disorder that prevents the respiratory muscles from functioning.
