Refractory lipoatrophy treated with autologous whole blood injection: A case report.

Background: Intramuscular corticosteroid injection may cause adverse effects such as dermal and/or subcutaneous atrophy, alopecia, hypopigmentation, and hyperpigmentation. Although cutaneous atrophy can spontaneously resolve, several treatment options have been suggested for this condition.

Case summary: In this paper, we report a case of corticosteroid injection induced lipoatrophy treated with autologous whole blood (AWB) injection, as the condition had been unresponsive to fractional laser therapy. A 29-year-old female patient visited the dermatology clinic complaining of skin depression on her right buttock area, which had appeared six months earlier. There had been only subtle improvement at the margins after fractional CO₂ laser treatment; therefore, after obtaining informed consent from the patient, AWB treatment was initiated. One month after the first AWB injection, the size and depth of the lesion had noticeably improved, and a slight improvement was also observed in discoloration.

Conclusion: Close observation is the initial treatment of choice for steroid induced skin atrophy; however, for patients in need of immediate cosmetic improvement, AWB injection may be a safe and cost-effective alternative.
