Porphyria Cutanea Tarda Masquerading as Epidermolysis Bullosa Acquisita: A Report of Two Cases.

Porphyria cutanea tarda (PCT) is the most common type of porphyria worldwide and is often initially diagnosed when cutaneous manifestations arise. We present two patients where misdiagnosis of PCT occurred due to the condition masquerading as epidermolysis bullosa acquisita histologically. In patients with undifferentiated bullous/erosive skin conditions occurring in photo-distributed regions, PCT should be considered in the differential diagnosis irrespective of histopathological findings on biopsies and further investigated and treated appropriately.
