Febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is a rare subtype of pityriasis lichenoides et varioliformis acuta, characterized by an acute onset of ulceronecrotic papules, rapidly coalescing into large ulcers with necrotic crusts, associated with high fever and severe systemic symptoms. We report a case of a 65-year-old woman with a resistant form of FUMHD successfully treated with a tumor necrosis factor-α (TNFα) inhibitor (infliximab). After 1 year of treatment, because of the recurrence of lesions and -occurrence of severe sepsis, we decided to change the therapeutic procedure by introducing intravenous immunoglobulin witch induced a spectacular improvement. Only few cases of FUMHD treated with intravenous immunoglobulin have been reported to date. In our case, we describe the first utilization of TNFα inhibitors in the treatment of FUMHD: TNFα inhibitors may be useful, particularly in resistant cases. Further reports are required to confirm this potential therapeutic option.

We report two cases of cutaneous granuloma induced by anti-TNF-α therapy: a 47-year-old man suffering from psoriatic arthritis treated with infliximab and a 56-year-old woman treated with adalimumab for polyarticular juvenile rheumatoid arthritis. The biospies confirmed the diagnosis of a ‘sarcoidosis-like’ reaction. No systemic involvement was observed. Such cases of noninfectious granulomatous diseases occurring during anti-TNF-α therapy are becoming increasingly frequent.

Calciphylaxis is a rare cause of skin ulcerations and necrosis in patients with both normal renal and parathyroid function. Although calciphylaxis appears to be on the increase, treatments are mainly empirical, especially for wound care. The lesions in calciphylaxis are typically very painful and carry a high risk of infection, with sepsis being the leading cause of death in this serious disease. We report two cases of nonuraemic calciphylaxis, which responded to treatment with pamidronate and wound management by negative pressure system.
