What is chromoblastomycosis caused by?
Chromoblastomycosis is a chronic infection caused by pigmented fungi which form specialized cells, muriform or sclerotic cells, in tissue. 64 It involves the dermis and epidermis where a variety of pathological changes occurs, ranging from pseudoepitheliomatous hyperplasia to granuloma formation. The organisms which cause this infection are found in the natural environment in plant debris or forest detritus. The main range of chromoblastomycosis involves the tropics and subtropics and the incidence of infection is highest in countries with a high rainfall. The disease is mainly seen in countries of central and northern South America, parts of Africa, particularly the east coast of southern Africa, the Far East, Japan and the West Pacific. 63 The infection is most common in males and in agricultural workers. The main causes are Fonsecaea pedrosoi and Cladophialophora carrionii, but other fungi also cause this infection.
What is the color of chromomycosis in amphibians?
“Classic” chromomycosis is seen in an otherwise clinically normal amphibian with nodules of 1 to 3 mm diameter ranging in color from white to brown or black . Hepatic granulomas may be palpated in larger amphibians. Transillumination of the coelomic cavity may reveal granulomas on the liver or other visible internal organs. Ulcers of the toes, ventral skin, and rostrum may be noted in some specimens with no obvious external nodules. Some amphibians may have internal granulomas with no visible cutaneous lesions.
Can chromoblastomycosis be detected by skin scrapings?
Chromoblastomycosis should be suspected in persons with chronic scaly or friable lesions of the extremities, especially in rural tropical climates. Microscopic examination of skin scrapings can provide a rapid diagnosis of chromoblastomycosis because the characteristic muriform cells can be seen in potassium hydroxide preparations, especially those containing black dots (see Fig. 262-1 ). These unique structures may also be readily observed with standard staining of skin punch biopsy specimens with hematoxylin and eosin ( Fig. 262-5 ). Although not absolutely necessary, culture can be performed to identify the specific cause of infection. Standard mycologic media (Sabouraud glucose agar), with and without cycloheximide, should be used and cultures incubated for at least 4 weeks. In culture, the fungal agents of chromoblastomycosis appear as dark molds. Under standard culture conditions, these fungi may be identified by the microscopic appearance of hyphae and reproductive structures. The muriform structures seen in tissue have been produced in vitro using low pH and the addition of propranolol, but this is not necessary for clinical diagnosis. 22 Exoantigen testing of the fungus has been developed to aid in identification, although this is not commonly used. 23 Serologic and skin tests have also been developed, but their use in this rare disease is limited to specialized centers in more endemic regions of the world.
What is the term for a group of chronic localized infections of the skin and subcutaneous tissue?
Chromoblastomycosis (also known as chromomycosis, Carrión mycosis, Lane–Pedroso mycosis, verrucoid dermatitis and black blastomycosis) is a term that describes a group of chronic localized infections of the skin and subcutaneous tissue, most often involving the limbs.1,7 It is characterized by raised crusted lesions as a result of excessive proliferation of host tissue. It is caused by traumatic inoculation of the skin with a number of brown pigmented (dematiaceous) molds. In tissue, the fungi basically occur as large, muriform, thick-walled dematiaceous cells.
What is CBM in medical terms?
Chromoblastomycosis (CBM) is a chronic, slowly progressive mycosis caused by traumatic implantation of dematiaceous fungi in the dermis. Formerly included within the subcutaneous mycosis group, it is now classified as traumatic implantation mycosis.
Where is CBM found?
CBM has a worldwide distribution, with higher prevalence in tropical and subtropical countries located between 30° N and 30° S, such as Madagascar, Brazil, Venezuela, Uruguay, Argentina, and Mexico. 5,6.
What is CBM in a sclerotic cell?
CBM is a mycotic infection of cutaneous and subcutaneous tissues characterized by the development in tissue of phaeoid muriform cells. The term “sclerotic cells,” as used for the characteristic cells seen in tissue in CBM, has been replaced by the term “muriform cells.” 20 A comprehensive review of this mycosis was published recently. 15
What is the treatment for chromoblastomycosis?
Treatment options include oral itraconazole (as monotherapy or with oral 5-flucytosine [5-FC]), locally applied heat therapy, cryosurgery, photodynamic therapy (PDT) using 5-aminolevulinic acid (ALA) irradiation, and combination therapy. [ 69] .
Is noxafil a triazole?
Posaconazole (Noxafil), a new triazole derivative, has been experimentally used to treat chromoblastomycosis. Posaconazole has received approval from the US Food and Drug Administration for prophylaxis against invasive Aspergillus and Candida infections in patients at high risk because of severe immunosuppression.
What is the best treatment for onychomycosis?
Newer, more effective antifungal agents have made treating onychomycosis easier. Terbinafine and itraconazole are the therapeutic agents of choice. Although the U.S. Food and Drug Administration has not labeled fluconazole for the treatment of onychomycosis, early efficacy data are promising.
Is Gris-Peg effective for onychomycosis?
Historically, the treatment of onychomycosis has been challenging. Orally administered griseofulvin (Grisactin, Gris-Peg) has been available for many years, but its use is limited by a narrow spectrum, the necessity for long courses of treatment and high relapse rates. The oral form of ketoconazole (Nizoral) is much more effective but carries a risk of hepatotoxicity. 6
How many fungal infections are caused by onychomycosis?
Onychomycosis accounts for one third of fungal skin infections. Because only about one half of nail dystrophies are caused by fungus, the diagnosis should be confirmed by potassium hydroxide preparation, culture or histology before treatment is started. Newer, more effective antifungal agents have made treating onychomycosis easier.
What causes white onychomycosis?
White superficial onychomycosis is caused by certain fungi that directly invade the superficial layers of the nail plate and form well-delineated opaque “white islands” on the plate. As the disease progresses, these patches coalesce to involve the entire nail plate. The nail becomes rough, soft and crumbly.
Is onychomycosis rare in children?
Onychomycosis in children is rare, with an estimated prevalence of 0.2 percent. 38 Most often, onychomycosis develops in children with immunosuppression (e.g., acquired immunodeficiency syndrome, chemotherapy, congenital immunodeficiency syndromes), a strong familial history of onychomycosis or extensive cutaneous mycosis (tinea capitis or pedis).
What is the term for a fungal infection of the nail bed?
Onychomycosis (tinea unguium) is a fungal infection of the nail bed, matrix or plate. Toenails are affected more often than finger-nails. 1, 2 Onychomycosis accounts for one third of integumentary fungal infections and one half of all nail disease. 1 Tinea unguium occurs primarily in adults, most commonly after 60 years of age.
What causes tinea pedis?
Some degree of tinea pedis is almost always present. The infection is usually caused by Trichophyton rubrum, which invades the nail bed and the underside of the nail plate, beginning at the hyponychium and then migrating proximally through the underlying nail matrix 2, 3 ( Figure 3).
