Eczematous dermatitis
Most common inflammatory skin disorder; several forms, including contact dermatitis, allergic contact dermatitis, and atopic dermatitis; intercellular edema and epidermal breakdown; erythematous pruritic weeping vesicles
Folliculitis
Inflammation and infection of the hair follicle and surrounding dermis; presence of inflammatory cells within the wall and Ostia of the hair follicle creates a follicular based pustule; from shaving, antibiotics, occlusive clothing, humidity; small pustule located over pilosebaceous orifice
Furuncle (boil)
Deep seated infection of the pilosebaceous unit; caused by staphylococcus aureus; hot red tender pustule that may rupture
Cellulitis
Diffuse, acute, infection of the skin and subcutaneous unit; caused by streptococcus pyogenes or S. aureus; borders not well demarcated; break in the skin, such as a fissure, cut, laceration, insect bite, or puncture wound
Tinea (dermatophytosis)
Group of noncandidal infections that involve the stratum corneum, nails, or hair; infection by dermatophytes, acquired by direct human or animal contact, lives off dead keratin; nails yellow thick and separated; lesions may be papular, pustular, vesicular, erythematous, or scaling
Pityriasis rosea
Self limiting inflammation of unknown cause; round or oval plaque, not contagious; lesions pale, erythematous, and macular with fine scaling; Christmas tree pattern on trunk
Psoriasis
Chronic and recurrent disease of keratin synthesis; increased epidermal cell turnover, increased numbers of epithelial stem cells, abnormal differentiation of keratin expression; well circumscribed dry silvery scaling papules and plaques
Rosacea
Chronic inflammatory skin disorder; does not itch, flushing due to sun, cold, emotion, hot drinks, spicy food, alcohol; telangiectasis, erythema, papules, and pustules in center of face; rhinophyma may occur (sebaceous hyperplasia of nose)
Herpes zoster (shingles)

Herpes simplex
Infection by herpes simplex virus; type 1 is oral, 2 is genital; tenderness, pain, paresthesia or burning; grouped vesicles on erythematous base

Basal cell carcinoma
Most common skin cancer; arises in basal layer of epidermis; shiny nodule that is pearly or translucent; open sore, crusting or bleeding, scar like area that is shiny and taut
Squamous cell carcinoma
Second most common skin cancer; arises in epithelium of sun exposed areas; elevated growth with a central depression, wartlike, scaly red patch with irregular borders, open sore may have crusting
Malignant melanoma
Lethal form of skin cancer that develops from melanocytes which migrate into skin, eye, cns, and mucus membranes; most arise de novo
ABCs of melanomas
A. Asymmetry of lesion
B. borders irregular
C. Color not same all over
D. Diameter is greater than 6mm
E. evolution..existing lesions change
Kaposis sarcoma
NeoplasM of the endothelium and epithelial layer of the skin; caused by kaposi sarcoma herpes virus 8, common with HIV; soft vascular blue purple painless lesions, macular or papular, plaques, keloids, or ecchymotic areas
Alopecia areata
Sudden rapid patchy loss of hair usually from scalp or face; cause unknown, genetic and environmental; also nail pitting, hair shaft poorly formed and breaks at skin, hair loss in sharply defined round areas
