Novel Management of Granuloma Formation Secondary to Dermal Filler with Intralesional 1444 nm Nd:YAG Laser Technique

Background: Dermal fillers for soft tissue for the treatment of face sagging, volume loss, and wrinkles have become popular among patients of all ages and ethnicities, and their use is becoming increasingly widespread. Aim: the goal of this study was to evaluate the effectiveness and safety of a micro-pulsed, 1444 nm Nd:YAG laser on dermal filler complications, in particular on granuloma management. Methods: A subcutaneous, 1444 nm Nd:YAG laser was used on five female patients (range age 52-68 years) with hyaluronic filler granulomas located on the face (two on the cheek area and three on the lips); three patients had self-injected the filler, buying it online. Before and after the therapy, the patients received a skin ultrasound to determine the form and location of the granulomas and to determine if there had been a full or partial resolution. During this study, all possible adverse effects at the treatment site were monitored. The 5-point Global Aesthetic Improvement Scale (GAIS) (0 point-no change; 1 point-25%, mild improvement; 2 points-50%, moderate improvement; 3 points-75%, good improvement; 4 points-100%, excellent improvement) was recorded at a 3-month follow-up. Results: good results were obtained in the treatment of filler granulomas with the intralesional 1444 nm laser, even if just a single treatment was performed (one intervention was effective for curing granulomas up to 5 mm in diameter). Three patients were satisfied with excellent improvement, and two patients experienced good improvement. The results are functional and aesthetically satisfying, as shown by photographic assessment. At the last follow-up, the granuloma had reduced or completely disappeared in all cases, and no infections, burns, scarring or fibrosis, episodes of severe bleeding, or other serious adverse effects had been reported. All subjects tolerated the post-treatment period well. Conclusions: Our findings showed that granuloma treatment with an intralesional 1444 nm Nd:YAG laser is a minimally invasive, easy, fast, efficient, and low-risk procedure.

Autoimmune/inflammatory syndrome induced by methylmethacrylate associated to seronegative antiphospholipid syndrome and diffuse large B-cell non-Hodgkin's lymphoma

BACKGROUND

Autoimmune/inflammatory syndrome induced by adjuvants has been associated with different substances used for cosmetic purposes; for example, silicone, methylmethacrylate, autoimmune disorders and cancer.

DISCUSSION

A 40-year-old man with a prior history of methylmethacrylate injection in the buttocks for aesthetic purposes 8 years ago, presented with deep venous thrombosis in the left leg 6 months ago, accompanied with inflammation, hardening, changes in colour, ulceration in the buttocks, arthritis, myalgias and fever. Weak and moderate lupus anticoagulant and low levels of anticardiolipin antibodies were present. Thoracoabdominal tomography showed hepatosplenomegaly and a pulmonary nodule, the biopsy of which showed chronic granulomatous inflammation. After a month, a new chest tomography showed multiple nodular pulmonary lesions. The new pulmonary biopsy showed a diffuse large B-cell non-Hodgkin's lymphoma which was treated with cyclophosphamide, doxorubicin, vincristine, prednisone, and rituximab for four cycles, with good response of the autoimmune/inflammatory syndrome, but partial response of the diffuse large B-cell non-Hodgkin's lymphoma.

CONCLUSION

We describe the first case of seronegative antiphospholipid syndrome and lymphoma associated with methylmethacrylate in a patient with autoimmune/inflammatory syndrome.
