Podiatric Dermatology Quiz: What Is Your Diagnosis Of This Disorder?
Can you identify the condition in the photo on the left?
An eruption of lichenified or excoriated nodules, these lesions are thought to arise from incessant scratching or repeated rubbing. Various conditions ranging from atopic dermatitis and obstructive biliary disease to diabetes and chronic renal failure may predispose individuals to this condition.
In terms of treatment, topical steroids may offer some relief. Intralesional steroids are more effective but impractical when this disorder is widespread. Clinicians can achieve satisfactory results for this condition with ultraviolet light phototherapy.
Which of the following is your diagnosis?
a) Disseminated superficial actinic porokeratosis
b) Seborrheic keratosis
c) Guttate psoriasis
d) Prurigo nodularis
