A 55-year-old woman presented with blistering on the back of her hands and shiny, thickened skin in her décolletage. Laboratory examination revealed increased urinary total and high carboxylated porphyrins and homozygosity for mutation C282Y in the HFE gene. ⋯ Pseudoscleroderma is a rare complication of PCT but can also constitute the first cutaneous symptom of the disease, leading the way to diagnosis. Usually, adequate treatment of PCT with normalization of porphyrin values also results in improvement of pseudoscleroderma.

As a rare antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis, eosinophilic granulomatosis with polyangiitis (EGPA, formerly Churg-Strauss syndrome) is characterized by asthma, severe peripheral eosinophilia and the presence of extravascular granulomas. Cutaneous involvement usually includes palpable purpura or cutaneous to subcutaneous nodes. We present the case of a 43-year-old woman with EPGA and the unusual cutaneous manifestation of livedo racemosa.
