Ringworm Causes Psoriasis and It Is Contagious
Eventually psoriasis is really the fungus! Yes, it is the fungal infection of the skin and it is contagious.
I am not saying that it is just fungal infection – Autonomic Nervous System dysfunction plays major role but what causes the primary immune reaction or suspected vasoconstriction in the skin?
Scaly plaques are full of bacteria no doubt about that but the primary cause of immune reaction and the reason why psoriasis plaque develop may be the same as in a disease called Tinea corporis generally known under the name ringworm.
What causes ringworm?
Ringworm (this term in medicine is referred as to – Tinea) is a fungal infection caused by dermatophyte fungus of the 3 genera: Microsporum, Epidermophyton and Trichophyton.
Depending on where the infection is localized the disease is called Tinea corporis (body), Tinea capitis (scalp), Tinea pedis (foot), Tinea unguium (nails – onychomycosis), etc…
The fungi that cause this disease are common organisms living on the normal skin of healthy person. However when there is some opportunity the fungus may spread and induce a rash or more serious skin lesions.
I think that one of those more serious skin lesions we call psoriasis.
Just look at the next photo where you can see the ringworm and psoriasis plaque side by side in one person.
The smaller patch is the guttate psoriasis plaque. The bigger patch is (probably) the fungal infection – at least the most dermatologists would say that after the first examination of the rash.
So it is very possible that psoriasis is “just” a fungal infection of the skin caused by the diminished blood flow in the upper part of the skin due to Autonomic Nervous System dysfunction.
The only difference between the ringworm and psoriasis is that in psoriasis the Autonomic Nervous System is underperforming and fungus can spread. It is easily deducted from the act that psoriasis spreads symmetrically. Basically due to localized vasoconstriction on the same spots on both sides of the body.
Psoriasis is really caused by ringworm fungus?
So what about the differences between psoriasis patch and ringworm rash?
The fact that psoriasis spreads symmetrically and it is more scaly mostly in the center of the lesions when compared to ringworm rash (Tine corporis).
Those two parameters could be easily explained by Autonomic Nervous System caused vasoconstriction (low blood flow also potentiated by coagulation cascade – fibrin and platelets aggregation) in psoriasis. When this happens the ringworm fungi can infect the skin more easily and mostly the immune system is not capable of killing it due to decreased blood flow in the area.
Proofs that psoriasis is the fungal infection
1. Broken off hair
One of the symptoms of fungal infections that cause Tinea corporis or Tinea capitis (fungal infection of the body and scalp respectively) is hair damage at the place of infected area. In case of Tinea capitis it is clearly visible that the hair is missing – bald patches on the scalp form usually the circles.
