scabies
Prurigo Nodularis
rare, chronic skin disorder that is characterized by intensely pruritic, hyperkeratotic, excoriated papules. Features of the “neuropathic itch” are the presence of paraesthesia, hyperesthesia or hypoesthesia, as well as burning, tingling, heat and cold sensation. “picker’s nodules.” itch-scratch cycle firm, dome shaped, itchy, discrete, scaly, red or brown in color and have a crusty or warty surface. 3mm to 20mm symmetrically distributed on the extensor surface of the arms and legs

Prurigo Nodularis
Keloids & Hypertrophis Scars (HS)
Hyperproliferative collagen growths at site of dermatological insult. Keloids proliferate beyond the borders of the dermal scar May take months or years to develop Does not regress over time. HS remain confined within the margins. Scar usually appears within four weeks of injury. May regress over time
Molluscum Contagiosum
Dermatologic disorder characterized by skin-colored, dome-shaped lesions on the skin. Lesions can be localized, chronic and can be debilitating 3rd most common viral skin infection in children. shiny, wax-like or pearl-like surface. crater-like central indentation. Direct skin-to-skin contact, Autoinoculation, fomites

Pemphigus Foliaceus
acquired autoimmune disorder, Presentation: diffuse, desquamating rash on scalp, face, and trunk, Lesions are tender on palpation, annular or arcuate erosions that crust and coalesce to form a diffuse rash, fragile and are easily ruptured, patient’s trunk, and tends to concentrate on the scalp, face, trunk, and chest

SJS
Rash morphology can range from disseminated atypical target lesions and bullous lesions to red coalescent macular exanthema and epidermal necrolysis Blistering, skin tenderness and epidermal necrolysis are the hallmark symptoms of SJS. Drug reaction, can also be from an infection. Begins with prodromal s/s. Skin falls off when you touch it — Nikolskys sign.
Angioedema
Self-limiting, localized swelling of the skin or mucosal tissues. Affects face, lips, throat, larynx, extremities, or bowel wall. extravasation of fluid into the interstitium due to a loss of vascular integrity. Can be allergic to food/meds, drug induced from ACE, Opiod, NSAID.
