1 Learning Objectives
1) Recognize common dermatologic manifestations associated with HIV 2) Understand diagnosis of dermatologic manifestations 3) Understand treatment modalities for dermatologic manifestations
2 HIV Dermatology • Presenting sign of HIV infection is skin manifestations • HIV positive individuals due to defects in cell immunity are predisposed to certain bacterial, fungal, viral, and mycobacterial disease with skin manifestations • Skin diseases which are common in general population are exacerbated in HIV with increased prevalence
3 American Academy of Dermatology HIV Dermatology
• Infectious Dermatoses • Noninfectious Dermatoses • CD4 count
4 HIV Skin Manifestations by CD4
• CD4 < 50: Bacillary angiomatosis, Cryptococcus • CD4 < 150: Histoplasma • CD4 any count: mycobacterium, Kaposi’s sarcoma, HSV, Herpes Zoster, HPV
5 Infectious Dermatosis
6 Infectious Dermatosis
• Syphilis • HPV • Cryptococcus • S.aureus • Histoplasma • HSV • Herpes Zoster • Tinea • Kaposi’s Sarcoma • Onychomycosis • Bacillary Angiomatosis • Scabies • Molluscum contagiosum
7 Case 1
• 50 y homeless M, CD4 22, VL 48K, not on ARVS for several years, lives next to a dumpster where a pregnant cat has been living. Presents with weight loss, fever, and skin lesions present for 6 months.
8 What is this disease?
NeovascularBacillary Angiomatosis nodular lesions or Bartonellosiseither single or in clusters with a reddish or violacious color

Bacillary Angiomatosis
• CD4 <50 • Bartonella henselae / Bartonella quintana • B.henselae associated with cats, cat scratch, and fleas • B.quintana associated with crowded low income area and louse infestation • Systemic lesions in Liver, spleen, bone, lymph nodes
10 Bacillary Angiomatosis
• B.henselae can cause Peliosis hepatica • Tissue biopsy shows lobular proliferation of small blood vessels, Warthrin Starry stain shows clusters of bacilli • Can isolate using PCR, blood culture • Doxycycline 100mg po BID • Erythromycin 500mg po QID( macrolides)
11 Bacillary Angiomatosis
• IV for bacteremia, endocarditis, bone • Four months or longer, may need chronic suppressive therapy • MAI prophlylaxis with Azithromycin appears to be protective against BA
12 Case 2
• 43 y MSM with HIV, CD4 250, not on ART for 1 year because he wanted to take a drug holiday presents with 2 months of R leg edema from thigh to foot and new skin lesions on his R heel.
13 What is this disease?
Similar in appearance to BA, slightly raised to nodular, redKaposi to violeceous’s Sarcoma color, can also be flat and more brown
14 http://visualsonline.cancer.gov Kaposi’s Sarcoma • Occurs at lower CD4 counts but can occur at ANY CD4 count • HHV-8 associated with all 4 forms • Higher prevalence in MSM regardless of HIV status • Cutaneous and systemic lesions including Lymphedema
15 Kaposi’s Sarcoma • Look similar to Bacillary Angiomatosis • Advanced disease lesions coalesce to form large plaques especially on upper thigh • MC visceral site is GI tract • Pulmonary involvement >50 lesions but can happen with little to minimal lesions, ominous sign
16 Kaposi’s Sarcoma
• ART can prevent / regress lesions • More extensive disease Heme/Onc consult for Chemotherapy • Radiation therapy for localized lesions • Avoid steroids
17 Case 3
• 22 y MSM, CD4 18, VL 5000, sexually active with multiple partners presents with diffuse small papules which initially appeared on his trunk but have spread to his axillae and face.
18 What is this disease?
2-5 mm painless flesh colored or pearly papulesMolluscum with umbilicated Contagiosum center usually in singles but can be grouped near each other
19 www.alphaderm.ca Molluscum Contagiosum
• Any CD4 count but worse with advanced AIDS • Poxvirus infects epidermal keratinocytes • Spread via skin to skin contact, contact with shavers, sex toys, contaminated towels/linens • Can be located in groin, trunk, axilla, face, more widespread in HIV
20 Molluscum Contagiosum
• Improves with ART but can be difficult to eradicate • Cryotherapy with liquid nitrogen • Local excision with curretage • Topical Imiquimod • Tretinoin • Trichloroacetic acid • Laser therapy 21 Case 4
• 55 y homeless M with CD4 11, taking his ART intermittently, has been living in a shelter for 3 weeks c/o of crusty pruritic skin which got worse after using hydrocortisone cream
22 What is this disease?
Scabies Norwegian (Crusted) Scabies
23 webmd.com Scabies • Can occur at any CD4 count • Scaly pruritic papules or hyperkeratotic plaques on palms, soles, trunk, extremities • Infestation with mite Sarcoptes scabiei • Burrows between fingers and toes • Occurs in crowded areas, institutionalized, homeless • Skin scraping of burrow, skin biopsy
24 Scabies
• Superinfestation in Norwegian scabies occurs in advanced AIDS, MSM, HTLV co- infection • Permethrin 5% cream once, can reapply after 14 days • Need to treat household contacts • Ivermectin 200 mcg/kg oral, at least 2 doses taken 7 days apart
25 Non-Infectious Dermatoses
26 Non-infectious Dermatoses
• Psoriasis • Eosinophilic Folliculitis • Seborrheic Dermatitis • Atopic Dermatitis • Xerosis • Prurigo nodularis • Hypersensitivity to insect bites

Case 5
• 48 y M newly diagnosed with HIV, CD4 150, VL 76K, presents with 4 months of raised red pruritic lesions often with a pustule.
29 What is this disease?
Raised pruriticEosinophilic nodules with Folliculitis pustular head on erythematous base 30 Courtesy of Dr.Stephen Raffanti Eosinophilic Folliculitis
• Occurs at CD4 counts 250 or lower • Lesions look similar to bacterial folliculitis • Inflammatory condition and often diffuse • Skin biopsy: Intense infiltration of eosinophils around sebaceous glands/hair follicles, no PMNS or organisms • Peripheral eosinophilia
31 Eosinophilic Folliculitis
• Improves with ART • Topical steroid creams,oral antihistamines for mild disease • Isotretinoin, Itraconazole, Phototherapy, moderate to severe disease
32 Case 6
• 48 y M newly diagnosed with HIV, CD4 275, c/o of stiffness of his knee joints and multiple scaly patches of skin covering his arms and trunk. He noticed a couple of patches 2 years ago when his HIV test was negative.
33 What disease is this?
Well circumscribedPsoriasis erythematous plaques with silver scaling 34 American Academy of Dermatology Psoriasis
• Any CD4 count • Worsening of psoriasis with HIV • Increase prevalence of psoriatic arthritis • Inverse psoriasis occurs in body folds, smooth shiny red lesions • Topical steroids, retinoids, vitamin D replacement not as effective in HIV • Responsive to ART
