What is the difference between chromoblastomycosis and Phaeohyphomycosis?

Phaeohyphomycosis refers to infections caused by many kinds of dark, melanin-pigmented dematiaceous fungi. It is distinguished from chromoblastomycosis and mycetoma by the absence of specific histopathologic findings. (See also Overview of Fungal Infections.

What are sclerotic cells?

Sclerotic cells, also known as Medlar bodies, are globe-shaped, cigar-colored, thick-walled structures that are 4-12 µm in diameter (see the image below). Sclerotic cells on a potassium hydroxide preparation. Medlar first described them in 1915.

What are systemic mycoses?

Systemic mycoses are fungal infections affecting internal organs. In the right circumstances the fungi enter the body via the lungs, through the gut, paranasal sinuses or skin.

What is the cause of Phaeohyphomycosis?

Phaeohyphomycosis is a group of mycotic infections caused by dematiaceous fungi (pigmented) that contain melanin in their cell walls.

What are the symptoms of Phaeohyphomycosis?

Subcutaneous phaeohyphomycosis is characterised by papulonodules, verrucous, hyperkeratotic or ulcerated plaques, cysts, abscesses, pyogranuloma, non-healing ulcers or sinuses.

How do we treat patients with Chromomycosis?

Although early, small lesions of chromoblastomycosis can be treated with surgical removal, long-term oral antifungal therapy is the treatment of choice for more extensive disease. Severe disease is often refractory to treatment.

Which fungi causes systemic mycoses?

ABSTRACT Systemic mycoses are caused by certain species of Deuteromycetes and Schizomycetes. The primary infection occurs in the lung and is acquired by inhaling spores or hyphae. The severity of the infection varies from a sub- clinical type to a disseminated and often fatal disease.

What organisms cause systemic mycoses?

The termsystemic mycoses is used here to refer to infections caused by organisms in the following genera:Blastomyces, Coccidioides, Paracoccidioides, Histoplasma, andCryptococcus. In most cases, the infection develops initially in the lungs; later, the skin and other organs may be involved.

What is the difference between cutaneous and subcutaneous?

The term “cutaneous” refers to the skin. Subcutaneous means beneath, or under, all the layers of the skin. For example, a subcutaneous cyst is under the skin.
