cause superficial infections of the epidermis, hair and nails
Cutaneous Mycoses
penetrate the epidermis and dermis to infect deeper tissues?
Subcutaneous mycoses
spread through the body
Systemic mycoses
cutaneous mycoses is classified as: (2)
Dermatophytoses
Dermatomycoses
cutaneous mycoses caused by genus Epidermophyton
Dermatophytoses
Dermatophytoses samples
Epidermophyton microsporum
Epidermophyton trichophyton
cutaneous mycoses caused by other fungi, the most common is Candida species
Dermatomycoses
caused by saprophytic (soil-growing) fungi that enter tissue, usually through trauma.
Subcutaneous Mycoses
most common subcutaneous nodular fungal disease
sporotrichosis
causative agent of sporotrichosis
Sporothrix schenckii
traumatic implantation of fungal elements from contaminated soil, thorns or wood splinter
subcutaneous mycoses
agents of subcutaneous mycoses
jeanselmei
wnagiella dermatitidis
treatment for subcutaneous mycoses
antifungal drugs
topical drugs (applied directly on affected areas) such as creams, gels, lotions, solutions or shampoos.
foods preventing skin fungus

home remedy
- Tea Tree Oil (antifungal & antibacterial)
mixed with coconut or olive oil applied in ifected area - Hydrogen Peroxide
chronic, localized infections of the skin and subcutaneous tissue following the traumatic implantation of the etiologic agent

causative organisms of mucormycosis
lictheimia, saksenaea
causative organisms of lobomycosis
loboa loboi
causative organisms of rhinosporidiosis
Rhinosporidium seeberi
in subcutaneous mycoses, lesions begin as small, hard nodules resembling _____ and may spread slowly in the _____ and continue to develop over a period of many years.
keloids ; dermis
chromomycosis or veruccous dermatitis
chromoblastomycosis
chromoblastomycosis 2 species implicated:
fonsecaea pedrosoi
phialalophora verrucosa
clasdosporium type and rhino cladiellatype of conadiation
fonsecaea pedrosoi
phialophora type (flowers in the vase of conidiation)
phialalophora verrucosa
fungi found growing on plant debris, wood and soil
phialalophora verrucosa
lesion: confound to extremeties such as
feet or lower legs
lesion: confound to extremeties such as feet or lower legs which is also a _____ suface
cauliflower-like surface
the lesion is non-budding and presence of _____
sclerotic bodies
fungal infections affecting internal organs entering the body through the lungs, gut, parnasal sinuses or skin.
systemic mycoses
ex. of systemic mycoses
Coccidiodes immitis
Histoplasma capsulatum
Blastomyces dermatitidis
Paracoccidioides basiliensis
systemic mycoses are caused by certain species of
Deuteromycetes and Schizomycetes
systemic mycoses effectic drug
Amphotericin B
Azoles (fluconazole, triazole, itraconazole)
caused by thermally-diagnostic blastomyces species found in soil
Blastomycosis
occurs via inhalation of conidia which often cause acute pulmonary symptoms
Blastomycosis dermatitidis
Blastomycosis gilchristii
diagnostic tests:
- fungal culture
- Ag detection by enzyme immunoassay ; using serum or urine, but can be used for bronchoalveolar lavage (BAL) fluid or CSF (cross reactions can occur but + result can help guide diagnosis.
- Fungal stains on cytological or histopathologic samples: Sputum, BAL, Lung biopsy or other tissue sample (False - can occur)
- antibody tests: immunodiffusion and complement fixation tests (have low sensitivity and specificity therefore not reliable)
- PCR : to confirm culture and histopathologic samples.
