(164 cards)

urticaria - wheals on a erythematous base which is blanchable suggesting inflammation, may be pruritic, red, or skin-colored. May last a few minutes to 24 hours and may need antihistamine to alleviate the burning/itching.

Nonbullous impetigo - well-localized area of papules and pustules with surrounding erythema and thick, adherent, golden-colored crust located on the chin.

Diaper candidiasis - diffuse, confluent erythema with discrete erythematous papules and plaques, superficial scale and satellite lesions to the inguinal area

Miliaria Rubra: Scattered vesicles on an erythematous base, usually on the face and trunk
Result from obstruction of the sweat gland ducts
Disappears spontaneously within weeks

Malignant melanoma - think ABCDE-EFG - assymetry, irregular borders, different colors especially blue and red, diameter > 6 mm, evolving or changing, elevation, firm to palpation, growing rapidly over several weeks

squamous cell carcinoma - keratoacanthomas are SCCs that arise rapidly and have a crateriform center, often have a smooth but firm border, SCCs can become quite large if left untreated. Highest sites of metastasis are the scalp, lips and ears.

herpes zoster “shingles” - grouped vesicles on erythematous base usually in a dermatomal distribution that does not cross the midline (unilateral)

solar lentigo - happens on sun-exposed skin. Light brown and uniform in colr but may be assymetric

Slate blue patches: A dark or bluish pigmentation over the buttocks and lower lumbar regions
Common in newborns of African, Asian, and Mediterranean descent
Result from pigmented cells in the deep layers of the skin
They become less noticeable with age and usually disappear during childhood
Document these pigmented areas to avoid later concern about bruising

acanthosis nigricans - dark, velvety patches appearing in creases and folds of the body, i.e. axillae, neck, groin, occurring in people who are obese, have DM or metabolic syndrome. May be corrected with weight loss and resolution of underlying condition.

Coxsackie Virus (hand, foot, and mouth disease) - common in summer and fall, generally not painful and is contagious (person-to-person, touching of surfaces, droplet, touching fecal matter of infected individual). It happens mostly in children under 5 years of age but anyone can get it. It may consist of vesicles on a erythematous base on the soles and palms. The person may also have mouth sores, anorexia, sore throat, be fussy. It will go away with supportive treatment.

Seborrheic keratosis - often verrucous texture, appear like flattened ball of wax, may crumble or bleed if picked, may be erythematous if inflamed, common in older adults, non-cancerous and may appear as brown, black or skin-colored, appears on face, back, shoulders and chest

Molluscum contagiosum - caused by pox virus, pearly colored dome-shaped papules with umbilication, may appear in clusters or linear fashion (likely due to scratching)

Cutis marmorata - seen in normal children and and congenital hypothyroidism and Down syndrome. Vasomotor response to cooling or chronic exposure to radiant heat.

actinic keratosis - often easier to feel than see, superficial keratotic papules “come and go” on sun-damaged skin, pre-cursor to SCC

Dermal nevi - brown dome-shaped papule. Uniformly round and symmetric. Elevated and smooth, approximately 7 mm in diameter.

Tinea corporis of face: round, annular lesion with advancing red, scaly border noted on left cheek. Border is raised. Central hypopigmentation with red papules noted in center.

Café-au-lait spots: Pigmented light-brown lesions (<1 to 2 cm at birth)
Isolated lesions have no significance, but multiple lesions with sharp borders may suggest neurofibromatosis

plaque psoriasis - scattered erythmatous to bright pink well-circumscribed flat-topped plaques on extensor knees and elbows with overlying silvery scale

varicella “chicken pox” - dew drop on a rose petal appearance, now less common due to vaccinations. Lesions consist of a vesicle on erythematous base. Signs and symptoms include pruritis, fever, unwell symptoms.
Wild chicken pox (presently more common), is more virulent, lesions may become infected causing sepsis and death

basal cell carcinoma - pearly pink plaque with central depression and overlying arborizing telangiectasias on left cheek. It is the most common type of skin cancer, often appearing on sun-exposed areas.

Erythema infectiosum “fifth disease” - caused by parvovirus B19, starts with mild fever, rhinitis, headache (contagious) followed in 3-5 days with rash, no longer contagious. Appearance includes slapped cheek red rash on face and lacy rash on arms, legs and trunk.

acrocyanosis - a blue cast to the hands and feet when exposed to cold is very common in newborns for the first few days and may recur throughout early infancy. If acrocyanosis does not disappear within 8 hours or with warming, cyanotic congenital heart disease should be considered.

Physiologic jaundice in newborn - may appear in days 2-3, peaks at day 5. Jaundice within 24 hours of birth is concerning for pathologic cause. Description is based on its extension which happens from head down, i.e. “jaundice to nipple line”
