Answer

Generally, no laboratory studies are required. Screening for diseases causing immunosuppression (eg, HIV, hematologic malignancies) and/or renal failure is appropriate when new lesions of classic porokeratosis of Mibelli (PM) or disseminated superficial porokeratosis (DSP) are seen or when sudden exacerbation of any form of porokeratosis develops.
