Poststeroid panniculitis: a rare complication of systemic corticosteroid therapy.

We report a 9-month-old male patient with autoimmune enteropathy treated with intravenous methylprednisolone who developed firm, red, subcutaneous nodules 20 days after abrupt steroid interruption. The diagnosis of poststeroid panniculitis (PSP) was made based on clinical and histological grounds. PSP is an unusual complication of systemic corticosteroid therapy, which might occur following rapid steroid tapering or withdrawal. Physicians should be aware of this rare condition and distinguish it from other causes of erythematous subcutaneous nodules and plaques in children.
