Allergy to the sun: the causes

There are different forms (more or less common and serious) of solar allergy: benign summer lucite, polymorphous lucite, solar urticaria, photosensitization. The causes of these solar allergies are different depending on the type of allergic reaction.

1 - The benign summer lucite.

Benign summer lucitis is an allergic skin reaction triggered by sun exposure. It is the most common form of solar allergy, reaching 10 to 20% of the population. It most often affects young women (15-35 years old) and young children. As the name suggests, it is a mild form of solar allergy, but it can still be extremely annoying.
Summertime lucite usually occurs after one or two days of sun exposure, and it tends to disappear as the skin becomes tanned.

2 - The polymorphous lucite.

This form of lucite, much rarer than benign summer lucitis, is seen in men as well as women, and in people of any type. The cause of polymorphic lucite is exposure to sunlight. In contrast to benign summer lucite, polymorphic lucite reaches in particular the face, and it does not diminish with tanning, since the natural protection of the skin towards the sun has no positive effect on this form of solar allergy.

3 - Solar urticaria.

More than an allergy itself, solar urticaria is a variety of urticaria. This skin condition can be triggered by cold, friction ... and also by the sun.

4 - Photosensitization.

Photosensitization is an allergic reaction of the skin caused by the combination of sun with locally applied substances (perfumes, deodorants, creams ...), or certain medicines (antibiotics, anti-inflammatories, diuretics ...).

Erotomania: treatments

Erotomania should not be confused with nymphomania, which is rather linked to a pathological exaggeration of sexual desires. Erotomania does not look like this since the lived history (imagined), more attached to fantasized love passion than to sexuality, is most often platonic. On the other hand, some temporary 'passionate fixations' can be likened to erotomania, especially in the phase of hope and spite

Twelve genes were identified as being involved in the occurrence of pheochromocytomas and paragangliomas (same tumor as pheochromocytoma, but located outside the adrenal gland). Doctors assume that there are other genes involved. But these genes not yet discovered do not explain all the remaining 60% pheochromocytomas
