Sclerema neonatorum treated with intravenous immunoglobulin: a case report and review of treatments.

Sclerema neonatorum (SN) is a rare neonatal panniculitis that typically develops in severely ill, preterm newborns within the first week of life and often is fatal. It usually occurs in preterm newborns with delivery complications such as respiratory distress or maternal complications such as eclampsia. Few clinical trials have been performed to address potential treatments. Successful treatment has been achieved via exchange transfusion (ET), but its use in neonates is declining. Similar to ET, intravenous immunoglobulin (IVIG) enhances both humoral and cellular immunity and thus may decrease mortality associated with SN. We report a case of SN in a term newborn who subsequently developed septicemia. Biopsy showed subcutaneous, needle-shaped clefts without associated necrosis, inflammation, or calcifications. Treatment with IVIG led to notable but short-term clinical improvement. Sclerema neonatorum remains a poorly understood and difficult to treat neonatal disorder. Although IVIG did not prevent our patient's death, further studies are needed to determine its clinical utility in the treatment of this rare disorder.

New side effect of TNF-alpha inhibitors: morphea.

An otherwise healthy 45-year-old man with a 3-year history of poorly controlled psoriasis (no arthritis) was treated with etanercept 50-mg subcutaneous injections twice weekly for 3 months and then once weekly. Alternative treatment options were either unavailable (long commute for phototherapy) or contraindicated (history of alcohol abuse). The patient initially tolerated etanercept well with significant clinical improvement and had an uneventful course; however, approximately 18 months after initiating therapy, he abruptly developed dusky, indurated, and tender plaques on his abdomen and thighs at the sites of etanercept injections (Figure 1). There was also diffuse woody induration involving his flanks and back where injections had not been performed. His only recent prior exposure to an injectable medication was rabies vaccination in his arm 1 year earlier. The patient denied any systemic symptoms. Upon noting these findings, etanercept was immediately discontinued. Biopsy of an indurated plaque on his right lower abdomen revealed a superficial and deep perivascular lymphoplasmacytic inflammatory infiltrate in a background of thickened and hyalinized collagen fibers with notable loss of perieccrine fat (Figure 2). These features were most consistent with the inflammatory stage of morphea. Further work-up revealed a negative antinuclear antibody, anti-double-stranded DNA, anti-Scl-70, and anti-centromere. Borrelia titers were not obtained. The differential diagnosis included scleredema and scleromyxedema; serum and urine protein electrophoresis were within normal limits. The sites were treated with intralesional corticosteroids. During the next 3 months, there was minimal progression of disease although the plaques of morphea had not yet resolved.
