There is no diagnostic test for<unk> . The diagnosis is a clinical one. The characteristic lesions are the ischemic skin lesions (usually with areas of skin necrosis). The necrotic skin lesions (i.e. the dying or already dead skin areas) typically appear as violaceous (dark bluish purple) lesions and/or completely black leathery lesions. They can be extensive and found in multiples. The suspected diagnosis can be supported by a skin biopsy, usually a punch biopsy, which shows arterial calcification and occlusion in the absence of vasculitis. Excisional biopsy should not be done due to increased risk of further ulceration and necrosis. Bone scintigraphy can be performed in cases where skin biopsy is contraindicated. Results of the study show increased tracer accumulation in the soft tissues. In certain patients, an anti-nuclear antibody test may play a role in diagnosis of<unk> . Plain radiography and mammography may also show calcifications but these tests are less sensitive. Laboratory studies, such as phosphate levels, calcium levels, and parathyroid levels, are nonspecific and unhelpful for diagnosis of<unk> .
