Mycobacterium abscessus infection after facial injection of argireline:A case report

BACKGROUND The incidence of infection with Mycobacterium abscessus(M.abscessus)has increased in recent years.This increase is partly associated with invasive cosmetic procedures.CASE SUMMARY The purpose of this case summary is to increase clinicians'awareness of M.abscessus infection and reduce mycobacterial infection caused by cosmetic procedures.We report the case of a 45-year-old woman who received acetyl hexapeptide-8(argireline)injections in the forehead and temples,and erythema,nodules,and abscesses appeared at the injection sites after one week.The pus specimens were examined by microbiological culture and confirmed to be positive for M.abscessus.Clarithromycin 500 mg twice daily and moxifloxacin 400 mg once daily were administered for 5 mo and the lesions gradually subsided.CONCLUSION We report here for the first time a case of infection with M.abscessus after argireline injection.This condition is easily misdiagnosed as a common bacterial infection.Microbiological examinations are helpful for diagnosis and standardized cosmetic procedures can prevent infection with M.abscessus.

Disseminated infection by Fusarium solani in acute lymphocytic leukemia:A case report

BACKGROUND In recent years,the rate of immunosuppressed patients has increased rapidly.Invasive fungal infections usually occur in these patients,especially those who have had hematological malignances and received chemotherapy.Fusariosis is a rare pathogenic fungus,it can lead to severely invasive Fusarium infections.Along with the increased rate of immune compromised patients,the incidence of invasive Fusarium infections has also increased from the past few years.Early diagnosis and therapy are important to prevent further development to a more aggressive or disseminated infection.CASE SUMMARY We report a case of a 19-year-old male acute B-lymphocytic leukemia patient with fungal infection in the skin,eyeball,and knee joint during the course of chemotherapy.We performed skin biopsy,microbial cultivation,and molecular biological identification,and the pathogenic fungus was finally confirmed to be Fusarium solani.The patient was treated with oral 200 mg voriconazole twice daily intravenous administration of 100 mg liposomal amphotericin B once daily,and surgical debridement.Granulocyte colony-stimulating factor was administered to expedite neutrophil recovery.The disseminated Fusarium solani infection eventually resolved,and there was no recurrence at the 3 mo follow-up.CONCLUSION Our case illustrates the early detection and successful intervention of a systemic invasive Fusarium infection.These are important to prevent progression to a more aggressive infection.Disseminate Fusarium infection requires the systemic use of antifungal agents and immunotherapy.Localized infection likely benefits from surgical debridement and the use of topical antifungal agents.
