CASE PRESENTATION
A male patient, 28 years of age, was admitted to our hospital because of
recurrent papules, nodules, and intense itching on the trunk and
extremities for 12 years. The patient had visited another hospital 12
years ago (in 2010). He was diagnosed with EBP based on examination
results from other hospitals
(Figure1A) and herpetic
autoantibody test results.
The patient had visited other hospitals several times due to disease
relapse, but the outcomes were often unsatisfactory (Figure2). The
patient came to our hospital on August 2,2021. The physical examinations
revealed multiple reddish-brown hemispherical mung bean-to-soybean-sized
nodules were symmetrically distributed on the trunk and extremities,
densely packed in patches, some of which were anabrotic and crustosus
due to scratching (Figure 1C and 1D). Laboratory test results indicated
routine blood and urine test with normal liver and kidney function,
blood function, blood electrolytes, and blood sedimentation were normal.
