Paracoccidioididomycosis
*NO person to person transmission
Tx for LOCAL infection by systemic mpycoses
fluconazole
itraconazole
Amphotericin B for systemic
MISSISSIPI and OHIO river valleys
cause PNEUMONIA
Bad/bird droppings
HIDES in MPHAGES
HISTO
EAST of Mississipii and CENTRAL AMERICA yo!
inflammatory lung disease that can disseminate to BONE
forms GRANULOMATOUS NODULES
BROAD BASE BUDDING……..
BLASTO buds broadly….
SW US and California
pneumonia and meningitis
EARTHQUAKES release spores into air
forms SPHERULES filled w/ ENDOSPORES in tissues
Coccdio CROWDS in CALIFORNIA
*desert bumps= erythema noduosum
desert rheumatism- arthralgias
LATIN AMERICA
super cool looking budding yeast in a captain wheel formation
paracoccidioidomyocses
paracoccidio parasails w/ the captains wheel all the way ot latin america
Branching SEPTATE HYPHAE on KOH prep w/ BLUE fungal stain
Dermatophyte!….aka cutaneous fungal infections
Microsporum
Trichophyton
Epidermophyton
tinea capitis
Head and scalp
lymphadenopathy
alopecia
sclaing
Tinea corpis
BODY
ringworm (erythematous SCALING rings w/ a central clearing)
contact form infected cat/dog
tinea cruris
inguinal area
NO central clearing
Tinea pedis
interdigital- MC
mocassin
vesicular
Tinea unguium
onchomycosis
NIALS!!
Tinea Versicolor AKA….spaghetti and meatballs that occurs in SUMMER
yeas like fungus
degradation of LIPIDS> ACIDS….that damage MELANOCYTES> hypopigmentation or PINK patches
Opportunistic fungal infections
Candida Aspergillus Croptoccous Mucor/RHizopus PCJ Sporothrix schenckii
Pseudohyphae and budding yeasts at 20
GERM TUBES AT 37
CANDIDA ALBICANS
Septate hyphae that branch at FORTy FIVE degree angles
conidiophore /w radiationg chains of spores (SEEDING DANDELION!)
Aspergillus fumigatus
ACUTE Angles AFLATOXINS…not dimorphic
Yeasts w/ wide capsular halos and unequal budding on INDIA INK stain
Cryptococcus neoformas
irregular, braod NONSEPTATE hypae branching at WIDE angles
MUCORmycosis
IC: oral and esophageal thrush
DIabetics/ABx: vulvovaginitis
IV drug users: endocarditis
Candida
Asthma/CF: Allergic bronchopulomonary aspergiloosis> BRONCHIECTASIS AND EOSINOPHILIA
After TB infection: Aspergillomas in LUNG CAVITIES
Aspergillus…the SEEDING DANDELION
can produce AFLATOXIN > hepatocellular carcinoma
Soil, pigeon droppings
inhaled> hematogenous dissemination to meninges> SOAP BUBBLE LESIONS IN BRAIN
Cryptococcus neoformas
STaine w/ india inck and mucicarmine (REDDDD) but latex agglutination test for the polysaccharide capsular Ag is MORE SPECIFIC
Cryptococcus
Fungus in ketoacidotic diabetic/ neutropenic pts
MUCOR and RHIZPHOUS
fungi proliferate in VESSEL walls> penetrate cribiform plate and enter the BRAINNNNN
Frontal lobe abscess
cavernous sinus thrombosus
Black eschar on the face
CN involvement possible
Mucor
Rhizopus
Surgical debride
ampho B
