chronic progressive pulmonary histoplamosis | only a minority of pts w/ primary pulmonary histoplasmosis develop chronic disease; causes diffuse fibrosis, often w/ cavities followed by cor pulmonale | systemic mycoses |
chronic progessive histoplasma mediastinitis | lymphatic spread from primary lung infection; intense fibrosis can lead to compromise of vital mediastinal structures | systemic mycoses |
acute disseminated histoplasmosis | may involve the skin, mucous membranes, liver, heart valves, GI tract and CNS; occurs only in immunodeficient pts and simulates bacterial sepsis | systemic mycoses |
acute disseminated histoplasmosis | Sx: hepatosplenomegaly, Leukopenia, DIC, adrenal insufficiency | systemic mycoses |
chronic disseminated histoplasmosis | very uncommon, usu only occurs in immunocompetent older adults | systemic mycoses |
ocular histoplasmosis syndrome | central retinal degeernation and fivrous leading to vision loss | systemic mycoses |
ocular histoplasmosis syndrome | probably a Type IV hypersensitivity rxn rather than an active infection | systemic mycoses |
coccidioidomycosis | San joaquin Vally (CA), southwern USA (AZ), Western TX | systemic mycoses |
coccidioidomycosis | very large yeast form, fungal spherules contain multiple endospores, intense granulomatous inflammation | systemic mycoses |
primary coccidioidomycosis pneumonia | "valley fever," most pts are asym., fever, chronic cough, sob, frequently a/w erythema multiforme or erythema nodosum as a Type IV hypersensitivity response which indicates a vigorous cell mediated response | systemic mycoses |
coccidioidomycosis | lab: b/c of the level of infectivity of C. immitis, health care and lab personel who handle specimens are at risk of aerosol exposure; hospital outbreaks have occurred | systemic mycoses |
coccidioidomycosis | self-limited in immunocompetent individuals, "coin-like" lesions in lung; can be latent for many yrs | systemic mycoses |
acute disseminated coccidioidomycosis | can be hematogenously disseminated in pts w/ immune deficiency (lymph, bone, skin, subq. CNS) | systemic mycoses |
cryptococcosis | pigeon feces, most strains have a thick polysaccharide capsule (C. neoformans), therefore few immunocompetent pts get this | systemic mycoses |
cryptococcosis | prolonged aerosol exposure to soil and dust contaminated w/ pigeon droppings | systemic mycoses |
cryptococcosis | India ink stain | systemic mycoses |
candidiasis | C. albicans (mc) | opportunistic mycoses |
candiasis | all form pseudohyphae EXCEPT C. glabrata | opportunistic mycoses |
pseudohyphae | wall constriction separates strands rather than true septae | (blank) |
candiasis | most common fungal pathogen; common in hospitals | opportunistic mycoses |
candiasis | some risk factors: Diabetes, congenital immunodeficiency, post transplant w/ chronic corticosteroid use | opportunistic mycoses |
mucocutaneous candiasis | oral thrush, vulvovaginal thrush, balanitis (penile surface) | opportunistic mycoses |
mucocutaneous candiasis | scatterred erythematous lesions a/w "cottage cheese" exudate which forms pseudomembranes | opportunistic mycoses |
mucocutaneous candiasis | candidal esophagitis | opportunistic mycoses |

aspergillosis | aspergillus fumigate (mc) | opportunistic mycoses |
aspergillosis | granulomatous inflammation is usu only in immunocompetent pts , NOT immunodeficient | opportunistic mycoses |
aspergillosis | vasculotropic which leads to vascular destruction and down-stream necrosis and hemorrhage | opportunistic mycoses |
aspergillosis | leads to chronic inflammation of lungs (pneumonitis); increase in eosinophils | opportunistic mycoses |
