Mycetoma – Causes, Symptoms, Diagnosis, Treatment, and Prevention

Mycetoma, also known as “Madura foot,” is a chronic infection characterized by the formation of a painless ulcer or tumor-like lesion on the foot. It is caused by the invasion of certain types of fungi or bacteria into the skin and underlying tissues.

The initial symptoms of mycetoma may include swelling, redness, and a small, painless bump on the foot. As the infection progresses, the lesion can grow in size and become more pronounced, resembling a tumor. The affected area may also develop multiple sinuses or openings that drain pus or small grains.

The exact cause of mycetoma is not yet fully understood, but it is believed to occur when the fungus or bacteria enters the body through a cut or wound on the foot. The infection then slowly spreads to the surrounding tissues, leading to the development of the characteristic lesion. Certain factors, such as walking barefoot in contaminated environments or having a weakened immune system, can increase the risk of developing mycetoma.

Treatment for mycetoma often involves a combination of antifungal or antibiotic medications, surgical removal of the lesion, and wound care. In some cases, amputation may be necessary if the infection has spread extensively or if the foot is severely damaged. Early detection and prompt treatment are crucial in preventing the spread of the infection and minimizing complications.

What is Mycetoma

Mycetoma is a chronic, progressive, and debilitating fungal infection that primarily affects the skin and subcutaneous tissues, typically in the foot. It is characterized by the formation of a painless lesion, known as a tumor, which gradually progresses and can lead to extensive damage if left untreated.

The primary causative agents of mycetoma are a group of fungi known as actinomycetes, which are found in soil and other environmental sources. These fungi can enter the body through a break in the skin and establish an infection, leading to the development of granules within the tissues.

The initial symptoms of mycetoma often include a small swelling or nodule on the foot, which may later develop into an ulcer with draining sinuses. The presence of these sinuses allows the release of characteristic grains or granules from the lesion, which are often visible to the naked eye.

If left untreated, mycetoma can cause severe damage to the affected tissues, leading to deformities, bone involvement, and functional impairment. In advanced stages, the infection can spread to other parts of the body, such as the bones, joints, and organs, potentially causing life-threatening complications.

Early diagnosis and prompt initiation of treatment are crucial in managing mycetoma. Treatment options include antifungal medications, such as azoles and terbinafine, combined with surgical intervention to remove the infected tissues and promote healing. However, the success rate of treatment largely depends on the stage and severity of the infection.

In conclusion, mycetoma is a chronic fungal infection that primarily affects the skin and subcutaneous tissues, often resulting in the formation of a painless lesion and the release of characteristic granules. Early detection and appropriate treatment are essential in preventing complications and improving patient outcomes.

Causes of Mycetoma

Mycetoma is a chronic, painless infection that typically affects the foot, resulting in an ulcer or a subcutaneous lesion. The primary cause of mycetoma is a fungal or bacterial infection. The infection enters the body through a break in the skin, such as a cut or wound on the foot.

Once the infection enters the body, it can start to grow and spread, leading to the formation of a mycetoma. A mycetoma is characterized by the presence of swollen and inflamed tissues, as well as the formation of granules. These granules are small, grain-like structures that contain fungal or bacterial elements.

In some cases, mycetoma can be caused by a specific type of fungus, such as Madurella mycetomatis or Actinomadura madurae. These fungi are commonly found in soil and can be easily transmitted to humans through direct contact with contaminated materials. Other fungal species, such as Fusarium and Aspergillus, can also cause mycetoma.

It is important to note that mycetoma is a chronic condition and can take months or even years to develop after the initial infection. The exact reason why some individuals develop mycetoma while others do not is still not completely understood. However, certain factors, such as poor hygiene, close contact with infected individuals or animals, and working in occupations that involve exposure to soil, can increase the risk of developing mycetoma.

In summary, mycetoma is primarily caused by a fungal or bacterial infection that enters the body through a foot injury. The infection can lead to the formation of a mycetoma, characterized by the presence of swelling and granules. Various fungal species, as well as certain bacteria, can cause mycetoma. Certain factors, such as poor hygiene and occupational exposure, can increase the risk of developing mycetoma.

Common Mycetoma Symptoms

Mycetoma is a chronic infectious disease caused by a fungus or bacteria, which primarily affects the foot. It is characterized by the formation of a tumor-like mass or swelling, often painless, known as the mycetoma lesion.

Swelling and Tumor Formation

One of the most common symptoms of mycetoma is the presence of a swelling or tumor in the affected area. This swelling may gradually increase in size and become firm to the touch. The tumor-like mass is often painless and may appear anywhere on the foot.

Formation of Lesions

Mycetoma lesions are the hallmark of this disease. They can vary in size, shape, and color, ranging from small papules to large nodules. These lesions are usually painless and develop slowly over time.

As the disease progresses, the lesions may start to ulcerate, leading to the formation of open sores. These open sores may be recurrent and can become infected, causing additional complications.

Presence of Granules

Another characteristic symptom of mycetoma is the presence of grains or granules within the lesion. These granules can vary in color, depending on the causative organism, and are often visible to the naked eye. The granules are typically small and can be easily seen within the lesion.

It is important to note that not all mycetoma cases present with visible granules, as some causative organisms may not produce them. Therefore, the absence of granules does not rule out a mycetoma diagnosis.

If you experience any of these common symptoms of mycetoma, it is important to seek medical attention promptly. Early diagnosis and treatment can help prevent the spread of infection and minimize complications associated with this chronic disease.

Signs to Look Out For

If you suspect you may have mycetoma, there are several signs to look out for:


A mycetoma typically starts as a small lesion on the foot or other affected area. This lesion can appear as a painless swelling, ulcer, or growth.


As the mycetoma progresses, it may produce small grains or granules that can be seen in the discharge from the lesion. These granules are often colored and can range from white to black.

The presence of these granules is a characteristic feature of mycetoma and can help distinguish it from other conditions.

If you notice any of these signs, it is important to seek medical attention. Early diagnosis and treatment can help prevent the spread of the fungus and minimize the damage to the affected area. A healthcare professional will be able to evaluate your symptoms and provide appropriate treatment options.

Diagnosing Mycetoma

Mycetoma is a chronic and slowly progressive disease characterized by tumorous growths, which are caused by a deep-seated infection. The infection leads to the formation of granules, typically found in the foot, but can also occur in other parts of the body.

Physical Examination

A physical examination is the first step in diagnosing mycetoma. The healthcare provider will carefully examine the area of concern, looking for any characteristic signs of the disease. These include the presence of a painless lesion, often with swelling and an ulcer. The healthcare provider will assess the size, texture, and color of the lesion to gather more information.

In some cases, a mycetoma may resemble a tumor or abscess, making it important for a healthcare provider to differentiate between these conditions. The presence of grain-like granules within the lesion can help confirm a diagnosis of mycetoma.

Laboratory Tests

In addition to a physical examination, laboratory tests are crucial for diagnosing mycetoma. A sample of the lesion is collected for analysis, either through a biopsy or by swabbing the area. The collected sample is then sent to a laboratory where it is examined microscopically and cultured to identify the causative organism.

The examination of the sample allows healthcare providers to determine the presence of fungal or bacterial elements within the lesion. By identifying the causative organism, healthcare providers can tailor the treatment plan accordingly.

It is important to note that diagnosing mycetoma can be challenging, as the disease may mimic other conditions. Therefore, a comprehensive evaluation, including medical history, physical examination, and laboratory tests, is necessary for an accurate diagnosis.

Types of Mycetoma

Mycetoma is a chronic infection characterized by the formation of a tumor-like mass, typically in the foot. There are two main types of mycetoma: actinomycetoma and eumycetoma.


Actinomycetoma is caused by a bacterial infection. It usually affects the subcutaneous tissues and bones, resulting in the formation of an ulcer with a discharge of pus. The affected area may have swelling, pain, and limited mobility. The infection is often chronic and slow-growing.


Eumycetoma is caused by a fungal infection. It also affects the subcutaneous tissues and bones, leading to the formation of an ulcer with a discharge of pus. The main difference is the presence of characteristic granules in the discharge, which are composed of fungal elements. Eumycetoma is typically painless and may progress slowly over time.

In both types of mycetoma, the infection can spread to nearby tissues and organs if left untreated. Prompt diagnosis and appropriate treatment are crucial to prevent complications and achieve a successful outcome.

Treatment Options for Mycetoma

Mycetoma is a chronic infection caused by a fungus that commonly affects the foot. This condition leads to the development of a tumor-like lesion or ulcer, which contains a combination of fungal and bacterial elements.

Medical Treatment

The primary aim of medical treatment for mycetoma is to eradicate the infection and promote wound healing. Antifungal medications, such as itraconazole or ketoconazole, are commonly prescribed to target the fungal component of the lesion.
