Is mycetoma a tumor?
Introduction: Mycetomes are inflammotory pseudo-tumors that affect the skin, the subcutaneous tissues and sometimes the bones. Their treatment depends on the type of parasite. Fungal mycetomas, also known as eumycetomas, are treated primarily by surgery, while actinomycotic mycetomas are treated primarily with drugs.
What causes actinomycetoma?
Mycetoma infection can be caused by fungi or bacteria. When caused by fungi, it is referred to as mycotic mycetoma or eumycetoma. When it is caused by bacteria, it usually involves infection by the actinomycetes group; such cases are called actinomycotic mycetoma or actinomycetoma.
What is the hallmark of mycetoma?

What bacteria causes mycetoma?
Mycetoma may be caused by filamentous bacteria (actinomycotic mycetoma or actinomycetoma) or fungi (eumycotic mycetoma or eumycetoma). The most common bacterial causes are Nocardia brasiliensis, Actinomadurae madurae, Streptomyces somaliensis, and Actinomadura pelletieria.

What is actinomycetoma?
Actinomycetoma is a chronic bacterial subcutaneous infection caused by Actinomyces that affect the skin and connective tissue. It is, therefore, a form of actinomycosis. Mycetoma is a broad term which includes actinomycetoma and eumycetoma under it.
How is mycetoma diagnosed?
Diagnosis. The diagnosis of mycetoma is based on clinical presentation and identification of the causative organisms which can be detected by directly examining the grains that are discharged by the sinuses. The samples can be obtained from any open discharging sinus by Fine Needle Aspiration (FNA) or surgical biopsy.
What does mycetoma look like?
