RASH--DISTRIBUTION:
DIAGNOSTIC WORKUP
(Algorithmic Diagnosis of Symptoms and Signs)
If there are any exudates, a smear and culture for fungi and routine bacteria should be done. Skin scrapings may be examined microscopically with a saline or potassium hydroxide preparation to rule out scabies and fungi. A Wood's lamp examination is very useful in diagnosing various fungi. All isolated lesions should be biopsied.
Diffuse rashes require routine CBC, sedimentation rate, urinalysis, chemistry panel, ANA test, and VDRL test. If there is fever, blood cultures should probably be done. Skin biopsies in consultation with a dermatologist should be done in a timely fashion. Patch testing and intradermal skin testing should be done when appropriate. A dark field examination may be necessary. GI series and barium enemas may be necessary to look for GI neoplasms, Crohn's disease, and ulcerative colitis.

Pustular rash:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Have the patient describe the appearance, location, and onset of the first pustular lesion. Did another type of skin lesion precede the pustule? Find out how the lesions spread. Ask what medications the patient takes and if he has applied topical medication to his rash. If so, what type and when did he last apply it? Find out if he has a family history of a skin disorder.
Examine the entire skin surface, noting if it’s dry, oily, moist, or greasy. Record the exact location and distribution of the skin lesions and their color, shape, and size.

Papular rash:
History and physical examination
(Handbook of Signs & Symptoms (Third Edition))
Your first step is to fully evaluate the papular rash: Note its color, configuration, and location on the patient’s body. Find out when it erupted. Has the patient noticed changes in the rash since then? Is it itchy or burning, or painful or tender? Has there ever been discharge or drainage from the rash? If so, have the patient describe it. Also, have him describe associated signs and symptoms, such as fevers, headaches, and GI distress.
Next, obtain a medical history, including allergies; previous rashes or skin disorders; infections; childhood diseases; sexual history, including sexually transmitted diseases; and cancers. Has the patient recently been bitten by an insect or rodent or been exposed to anyone with an infectious disease? Finally, obtain a complete drug history.

Vesicles/Bullae/Pustules:
Diagnostic Approach
(Field Guide to Bedside Diagnosis)
Vesicles are less than 5 mm in diameter, and bullae are larger. If bullae, petechiae, purpura, or necrosis are present, look for an “allergen” such as HSV, strep, deep fungal infection, collagen disease (especially lupus), or occult neoplasm.
Erythema multiforme can be differentiated from a drug reaction by a dusky violet color and petechiae at the center of the lesion. A target or iris lesion is also characteristic of erythema multiforme.
Staphylococcal scalded skin syndrome can be differentiated from toxic epidermal necrolysis by superficial blisters and absence of oral lesions.
Multidermatomal or disseminated zoster in a young adult should suggest HIV infection.
