Glottic Staphylococcus aureus in a patient with systemic lupus erythematosus: videolaryngostroboscopic...

Systemic lupus erythematous (SLE) is an autoimmune disease commonly treated with steroid which leads to immunosuppression and increased susceptibility to infection. Chronic laryngitis with whitish lesion on the true vocal fold in SLE may be caused by opportunistic organisms, such as tuberculous, fungal and Staphylococcus aureus infections. Videolaryngostroboscopy may be helpful in leading to the diagnosis and optimum treatment of glottic S. aureus A woman in her 40s with SLE presented with progressively worsening hoarseness for 2 months, accompanied by sore throat and odynophagia. Videoendoscopy showed erythematous and oedematous bilateral vocal fold with whitish lesion seen at the edge of middle one-third while the videolaryngostroboscopic evaluation showed there was severe asymmetry of the bilateral vocal folds, with severely reduced amplitude during phonation where the vocal cords were not vibrating, aperiodic vibratory cycles and 'always open', incomplete closure of vocal cord pattern. Later, endolaryngeal microsurgery and biopsy of the lesion confirmed of glottic S. aureus Her symptoms and followed up videolaryngostroboscopy showed resolution to normal findings after 6 weeks of cloxacillin. S. aureus infection of the glottis is a differential diagnosis in a chronic laryngitis with leucoplakic lesion in an immunosuppressive patient. Videolaryngostroboscopy has an important role in diagnosis, evaluation and treatment decision.
