Poststeroid panniculitis is a rare disorder usually reported in children after a sudden decrease or withdrawal of corticosteroid therapy. We report a case in an adult, a finding very rarely reported in English literature. The case report is about a 34-year-old man with multiple erythematous, firm and tender subcutaneous nodules on both thighs and legs after the withdrawal of long-term doses of dexamethasone prescribed before and after surgery for a frontoinsular anaplastic oligodendroglioma. Histopathologic study revealed mainly lobular and also septal panniculitis with fat necrosis and characteristic needle-shaped clefts in radial arrangement within fat cells and multinucleated giant cells. The lesions resolved in about 5 months, after weight loss and application of topical corticosteroids for 1 month, leaving only residual hyperpigmentation.

Post-steroid panniculitis is an extremely rare phenomenon caused by inappropriate interruption of long-term systemic corticosteroid therapy. It usually occurs in children and is characterized by development of multiple subcutaneous nodules on the cheeks, arms, and trunk. Histologically it is a lobular type of panniculitis with characteristic needle-shaped clefts within adipocytes and numerous foreign-body giant cells.

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.
