Guttate psoriasis (eruptive psoriasis) is most common in children and young adults. It develops acutely in individuals without psoriasis or in those with chronic plaque psoriasis. Patients present with many small erythematous, scaling papules, frequently after upper respiratory tract infection with β-hemolytic streptococci. The differential diagnosis should include pityriasis rosea and secondary syphilis.
Pustular psoriasis is another variant. Patients may have disease localized to the palms and soles, or the disease may be generalized.
Why one more book on dermatopathology? Certainly there are many outstanding
encyclopedic textbooks already written and even recently updated. Why one more
atlas? Hopefully you will agree that this book is different. We have tried to pair clinical
and histologic photographs to enhance the reader’s appreciation for clinical-pathological
correlation. In addition, this text is meant to be user friendly whether you are
approaching dermatopathology from a background of dermatology or pathology.
