Onychomycosis (Nail Fungus) – Treatment, Pictures, Sub types, Causes

What is Onychomycosis?

Onychomycosis is a disease condition that affects the person’s nail plate found in either the toes or the fingers. It is a kind of fungal infection. Most often, the reported cases are the toenails. Some experts would call it as tinea unguium, which is known as one of the largest subclass of this nail disorder. When left untreated, it leads to progressive and insidious destruction of the person’s affected nail plate. It is most commonly reported in males in the elderly ages around 40 to 80 years old.


Subtypes of Onychomycosis

There are actually three common subtypes of Onychomycosis, namely:

1. Proximal Subungual Onychomycosis (PSO)

It is a kind of fungal infection that penetrates in the proximal part of the nail fold. Amongst the three subtypes, this kind of subtype is the least common especially in people who are healthy. It is more commonly reported in persons who are known to be immunocompromised or who have an immune system that is impaired. Its etiological factors are trichophyton rubrum and fungus.

What happens here is that the fungus will enter the person’s nail bed by the proximal part of the nail fold and the skin flap that covers the nail which is located behind the affected cuticle. The root, which is the place where the nail is made, is where the fungus forays and then right after that, it will precede towards the nail’s edge.

2. Distal Subungual Onychomycosis (DSO)

Amongst the three common subtypes of Onychomycosis, this is reportedly to be the most common subtype. The etiological factors that are associated with this kind of nail disorder are dermatophytes, fungus, and trichophyton rubrum.

It begins under the person’s nail which is located at the affected finger or toes’ edge. Just like the proximal Subungual Onychomycosis, the fungus will eventually spread over the matrix of the nail and will later on inflict both the nail bed and the nail itself. The person who has this kind of subtype will experience nail plate detachment from his or her nail bed as well as discoloration on the nail plate which is affected. In addition to that, his or her nails become thicker than before. Aside from that, persons with this nail disorder subtype will report to feel uncomfortable and painful especially whenever they wear foot wears or shoes, for that matter.

3. White Superficial Onychomycosis (WSO)

This last and final common subtype is the known to be the second commonly reported subtype of infection of the nails. The causative agent associated with this subtype is trichophyton mentagrophytes and dermatophytes.

When a person has this kind of subtype, he or she will manifest white patches which are tiny and appearing on the nail plate surface. When the fungal infection spreads, the affected nails will become dry out and eventually the nail’s surface crumbles and flakes. According to studies, it becomes like that because the fungus will eat on the nail keratin and protein for its nourishment leading to the weakening of the nail plate and eventually distorting it.

There are actually three kind of white superficial Onychomycosis or WSO which are dual and classical nail plate invasion, the ventral and superficial kind and lastly the pseudo kind of WSO that have fungal invasion in the affected nail plate, which is deep.
