[Generalized chronic erythema nodosum: to consider Weber-Christian disease].

BACKGROUND

Weber-Christian disease is a recurrent, non-suppurative, febrile nodular panniculitis, more frequent in young women. It is characterized by recurrent outbreaks of subcutaneous nodules, distributed symmetrically. It has an idiopathic origin, or it is secondary to pancreatic disease, physicochemical agents or alpha-1 antitrypsin deficiency. It can affect any tissue with body fat. Histologically is a lobular panniculitis without vasculitis.

CASE REPORT: 23-year-old woman. She was admitted with subcutaneous painful nodules in pelvic, gluteus and forearms, with erythematous and hyperpigmented plaques; ecchymosis in the right upper eyelid and bilateral hyposphagma; fever of 38 °C; diaphoresis and oral ulcers, not painful. The hemogram showed pancytopenia, elevation of acute phase reagents, amylase and normal lipase. Blood culture was negative. Antinuclear antibodies and complement were normal. Computed tomography of the abdomen showed disseminated hyperdensity in subcutaneous tissue. The biopsy showed lobular panniculitis without vasculitis compatible with WeberChristian panniculitis. The patient was treated with steroids and immunosuppressive therapy.

CONCLUSIONS

Infectious etiology and other causes of erythematous nodules were ruled out through clinical evolution and complementary studies. The patient presented spontaneous involution in several weeks and sometimes the lesions evolved to sterile abscesses, in addition to systemic clinical manifestations. Corticosteroid therapy was deemed successful.
