Undesirable effect of cosmetic lip augmentation with autologous fat tissue.

[BACKGROUND] Facial cosmetic procedures are commonplace nowadays, especially techniques that aim to increase lip volume. Full lips provide a youthful, healthy, feminine and sensual appearance. There are many techniques and materials used to recover the loss of contour that occurs with age.

[CASE PRESENTATION] An unusual case of fat tissue accumulation following cosmetic upper lip augmentation in a 61 year-old female was reported. Surgical treatment was performed for esthetic concerns. Microscopically, the tissue removed was composed of muscle fibers and mature adipocytes.

[CONCLUSION] Undesirable effects of esthetic treatment can occur and the clinician should be familiar with such complications to diagnose and manage them.
