Introduction

Just like you can get fungal infections on your feet, it is possible to develop fungus in your hands. Hand fungus is called ‘Tinea manuum’ but commonly known as ring worm infection. In Tinea manuum, there is a red, scaly rash with a slightly raised border which is shaped like a ring. Commonly you can get it by touching your groin or feet if they are also infected with Tinea or by touching fungus contaminated objects, soil or infected persons. also infected with Tinea or by touching fungus contaminated objects, soil or infected persons. So it is important and get hand fungus treatment.

Sometimes you may falsely identify a hand fungus as hand eczema as they may have certain similarities. Sometimes both these conditions can be associated with each other.

When eczema arises in your hands it is called hand dermatitis or hand eczema. It is a chronic long- lasting skin condition which is also as common as fungal infections. Hand eczema may lead to severe negative effects on the quality of your life and even on your social status. Hand fungus treatment is therefore mandatory.

Eczema or fungus on your hands will be visible as it is difficult to hide, that may be quite embarrassing when you are among others. It will especially affect negatively on people who use their hands for the occupation such as the chefs, attendants and salon workers. Eczema is not contagious, but hand fungus is. Both these skin conditions can be quite severe, but they are not life threatening.

Hand eczema versus hand fungus

Fungal infection and hand eczema may seem similar as both are red, itchy rashes. Hand fungus typically has a raised border commonly with central clearing. The appearance is like a ring. Hand eczema doesn’t have a raised border and middle of the rash does not clear as the rash spread. So there is difference between hand fungus and hand eczema.

Commonly hand fungus affects only one hand, although you may develop it on both hands. Hand eczema is commonly bilateral and symmetrical. Hand eczema can get several flares and remissions while not responding to over the counter antifungal medications. Even after treatment, eczema can only be controlled and can reappear. However, hand fungus will respond to OTC antifungals and may clear off completely if you treat it properly. If partially treated hand fungus can reappear too and if you develop resistance to treatment, the future treatment of the rash will be difficult.

Hand eczema can be genetic and may run in families. Hand fungus is not familial, but often family members can get infected by close contact as it is contagious.

Although hand fungus can sometimes have associated nail involvement, in hand eczema nails are not involved.

What are the risk factors to develop hand fungus?

What are the causes of hand eczema?

Hand eczema may be related to occupational exposure or house hold activities. It often affects people who are in to catering, cleaning, hair dressing, mechanical work and health care as they frequently come in to contact with chemicals and other irritating substances.

There can be a genetic association for hand eczema and it can run in atopic families. Atopy is the genetic tendency to develop allergic conditions like eczema, asthma and hay fever. Stress can be a risk factor for hand eczema.

If your hand eczema does not respond to over the counter medications and home remedies, seek help as stronger medications need to be prescribed. If you think that a certain substance at work or home is the culprit behind your eczema, your doctor will do a ‘patch test’ to identify which irritants or allergens are responsible. Your doctor will also discuss the practices and behaviors that may be contributing to your hand eczema and ways to avoid or modify them.

In summary

Hand fungus is clinically differentiated from hand eczema by following signs.

Most hand fungus affect only a single hand.
If both your hands are affected, the involvement is not symmetrical.
Skin markings become white because the surface is scaling. But in hand eczema skin markings will be increased.
The Tinea rash has a raised border
Nearby nails can get affected (Tinea unguium)

Hand eczema can get complicated with skin infections. This is because of repeated scratching that destroys your skin barrier leading to cracks and open sores. Skin infections can occur with bacteria, viruses and fungi on a hand with eczema.

When your hand eczema gets a superadded fungal infection, it may give a mixed picture.

The itching will be more as both conditions are known to itch. Scratching can lead to erosions and even oozing. Fungal infection can occur especially when you have wet eczema. Fungus thrives on warm moist skin. Treatment will be difficult as the steroids which are used to treat eczema can worsen the fungal infection. Therefore, oral antifungal medications like Itraconazole or Terbinafine may be needed. Sometimes treatment will take a course of 4-6 weeks to eradicate the fungus. Then the eczema can be controlled with local application of steroids.
