Clinical evaluation and identification of characteristics papules may allow a dermatologist to diagnose<unk> . The papules have a white center and are bordered with a red ring. After lesions begin to appear, the diagnosis for<unk>  can be supported by histological findings. Most cases will show a wedge-shaped connective tissue necrosis in the deep corium. This shape is due to the blockage/occlusion of small arteries. Individuals may be diagnosed with the benign form if only the papules are present. However, an individual may be diagnosed with the malignant form if involvement of other organs like the lungs, intestine and/or central nervous system occurs. The malignant, or systematic form of this condition may suddenly develop even after having papules present for several years. In order to quickly diagnose this shift to the malignant variant of the disease, it is important for individuals to have consistent follow-up evaluations. In these evaluations, depending on which organs are suspected to be involved, the following procedures and tests may be conducted: skin inspection, brain magnetic resonance tomography, colonoscopy, chest X-ray, and/or abdominal ultrasound.
