HIV presnetations Flashcards
Systemic: low grade fever, cough, HSM, tongue ulcer
Histoplasma capsulatum:
(causes only pulm symptoms in immuncompent hosts)
Oval yeast cells within MP, CD
CD4 <100
Dermatologic: fluffy white cottage cheese
C. albicans
Pseudophyhae, commonly oral if CD4 <100
Dermatologic superficial vascular proliferation
Bartonella henselae: causes bacillary angiomatosis
Biopsy reveals neutrophilic inflammation
GI: chronic, watery diarrhea
Cryptosporidium spp.
Acid fast cysts seen in stool CD4<200
Neuro: encephalopathy
JC virus reactivation, cause of PML
Due to reactivation of a latent virus, results in demyelination
CD4 <200
Neuro: abscesses
Toxoplasma gondii
Many ring enahcing lesions
CD4 <100
Neuro: meningitis
Cryptococcus
Indina ink reveals yeast with narrow based budding and large capsule
CD4<50
Neuro: retinitis
CMV
Cottom-wool spots on funduscopic exam and may also occur with esophagitis
CD4 <50
Neuro: dementia
Directly associated with HIV
Must differentiate from other causes
Oncologic: superficial neoplastic proliferation of vasculature
HHV8, do not confused with bacillary angiomatosis caused by B henselae
Biopsy reveals LYMPHOCYTIC inflammation (vs. PMN in B henselae)
Oncologic: hairy leukoplakia
EBV, often on lateral tongue
Oncologic: non Hodgkins’ lymphoma (large cell type)
May be associated with EBV
Often on oropharynx (Waldeyer’s ring)
Oncologic: SCC
HPV
anus or cervix
Oncologic: primary CNS lymphoma
EBV
Focal or multiple, differentiate from toxo
Respiratory: interstitial pneumo
CMV
Bx reveals cells with intranuclear (owl’s eye) inclusion bodies
