any disease caused by fungi.
mycosis fungoi´des a chronic or rapidly progressive form of cutaneous T-cell lymphoma (formerly thought to be of fungal origin), which in some cases evolves into generalized lymphoma. It may be divided generally into three successive stages: premycotic, associated with intensely pruritic eruptions; infiltrated plaques, or mycotic, characterized by the presence of abnormal mononuclear cells (Sézary cells); and mushroom-like tumors that often ulcerate. The tumor stage (d'emblée type) may develop without preceding lesions or prodromal symptoms.
opportunistic mycosis a fungal or funguslike disease occurring as an opportunistic infection. Fungi that may become opportunistic pathogens include species of Aspergillus, Candida, Mucor, and Cryptococcus. Successful treatment of opportunistic mycoses depends on identification of the specific organism causing the infection. Without effective therapy a systemic infection of this type can be fatal.

mycosis fungoides

Abbreviation: MF
Cutaneous T-cell lymphoma, esp. when the disease is first clinically apparent on the skin. The skin is marked by irregularly shaped macules, plaques, or nodules, which usually first appear on the trunk and may sometimes cause considerable itching. The rash may be difficult to diagnose or may be misdiagnosed as another form of dermatitis. Biopsy specimens may reveal atypical-appearing lymphocytes in the epidermis or collections of malignant lymphocytes in clusters called Pautrier's microabscesses. Eventually (e.g., 10 or more years after diagnosis), the malignant cells disseminate throughout the skin and into lymph nodes and internal organs.


Topical nitrogen mustard, phototherapy with psoralens and ultraviolet light, systemic chemotherapy, interferons, extracorporeal phototherapy, and electron beam radiation of the skin have all been used. The disease may be curable when treated in its very earliest stage.


The name “mycosis fungoides” is deceptive, as the disease is not fungal in origin.

superficial mycosis

Any of a group of fungus infections of the skin. Included in this group are erythrasma, tinea barbae, tinea capitis, tinea corporis, tinea cruris, tinea favosa, tinea pedis, tinea unguium, and trichomycosis axillaris.

systemic mycosis

Any of a group of deep fungus infections involving various bodily systems or regions. Included in this group are aspergillosis, blastomycosis, chromoblastomycosis, coccidioidomycosis, cryptococcosis, geotrichosis, histoplasmosis, maduromycosis, moniliasis, mucormycosis, nocardiosis, penicilliosis, rhinosporidiosis, and sporotrichosis.

Patient discussion about mycosis

Q. What is the best way to treat fungal infection so it wont come back every year at the same time?? I don't know where I got it from- maybe caught it in a public shower,some people say it develops while the foot is in the shoe for long hours- I'm not sure- but every fall, for like 5 years now, I've been having this fungal infection in a few spots in my feet. usually in the same exact spots and ewvery year another one show up. what to do to make it go away?? it's real ugly and itchy, can't stand it. any help would be appreciated...

A. i also used to have fungal infections (Athlete's foot). i just applied a topical anti fungal cream to treat it and then continued applying it for prevention and started to use sandals in public showers. and thank god, i don't have any now.
