Q

Allergic Contact Dermatitis (ACD)

A
  • IMMUNE MEDIATED!
  • Delayed-type hypersensitivity reaction- Requires sensitization!
  • 20% may initially present as localized eruption but then become generalized
  • T-cell mediated reaction elicited by contact with a previously sensitized chemical agent
  • The dominant symptom is PRURITUS!
  • Reaction typically occurs 48-72 hours after exposure

effluvium

24
Q

patchy scarring hair loss

Study These Flashcards
A
  • Discoid lupus erythematosus
  • Central centrifugal cicatricial alopecia (CCCA)
  • Acne keloidalis
  • Traction alopecia (end stage)
  • Infections
  • Trauma
25
diffuse scarring hair loss
* Lichen planopilaris * Chronic cutaneous lupus * Dissecting cellulitis
26
Male Pattern Hair Loss (MPHL)
minoxidil bid to damp scalp, can take months, scalp irritation. or finasteride - may drop PSA by 50 percent, sexual side effects
27
clinical presentation AA
* Abrupt onset; well circumscribed/demarcated, round patches (can be generalized) * Exclamation mark hairs; shedding is prominent * Nails: pitting, ridging, trachyonychia
28
Telogen Effluvium
• Shift of hair follicles from anagen (growing) to telogen (resting) • Can be triggered by stress, medications and hormonal changes hair pull positive, spontaneous resolution, diffuse shedding 3 mo after trigger
29
Traction Alopecia
Traction or pulling that causes inflammation Initially- temporary broken shaft Advanced- scarring without inflammation • Usually frontal and/or temporal • Can take years/decade to develop
30
mgmt traction alopecia
stop tension, permanece depends on how long
31
Central Centrifugal Cicatricial Alopecia (CCCA)
* Premature desquamation of inner root sheath → scarring * Attributed to trauma, chemicals and heating * Most common hair loss in AA females
32
CCCA presentation and mgmt
• Poorly defined areas of vertex and crown, w/centrifugal expansion • Shiny, smooth, white/gray peripilar halos and broken hairs • +/- inflammation Management • Stop stressful hair processing and grooming practices • Can still progress even though stop • High potency topical corticosteroids, tetracycline class abx
33
Lichen Planopilaris (LPP)
Clinical Presentation • 2 subtypes: classic and frontal fibrosing (FFA) • Perifollicular erythema and hyperkeratosis and scarring • FFA frontotemporal loss of both terminal and vellus hair • more than half also have alopecia of the eyebrow (may precede)
34
LPP dx
Diagnostics | • MUST take punch bx from area of active disease. Both horizontal & vertical
35
LPP mgmt
* Chronic, unpredictable, no cure, goal is prevention worsening * Treatment in earlier active (inflammatory) stage * First line: * High or super high potency topical steroids, tapered when erythema subsides; intralesional triamcinalone, q6wks 10mg/ml (5mg/ml if frontal areas); Using 30g needle, deposition of 0.1ml every 1cm into dermis 1-2mm (not to exceed 40mg in a single treatment)
36
Dissecting Cellulitis
• Most common AA young adult males; follicular occlusion tetrad Clinical Presentation • Firm boggy nodules and plaques • Sinuses and drainage Management • Intralesional corticosteroids, abx, oral isotretinoin, surgical
37
Hirsutism
• Increased number of terminal hairs in male pattern distribution • Caused by adrenal (tumor or hyperplasia), pituitary or ovarian tumors; medications Clinical Presentation • Terminal hairs androgen-dependent areas • Signs of virilization which can help differentiate diagnosis
38
Hirsutism dx and mgmt
Diagnostics • Labs: testosterone (free & total), LH, FSH, DHEA-S, androstenedione, fasting glucose Management • Based on underlying cause: i.e. OCPs for hormonal imbalance or dexamethasone for adrenal • Topical: efluornithine cream (Vaniqa) • Systemics: Spironolactone • Other: electrolysis or laser hair removal, waxing
