A 33-year-old man who had a 14-year history of systemic lupus erythematosus (SLE) was referred to us with texture change of axillary hairs for 6 years. He had been receiving 10 mg daily of oral corticosteroids andmizoribine, but the patient had never been obese. Clinical examination revealed pale yellow concretions sticking to the hair shafts (Fig.1a, b) [1]. A Corynebacterium species was identified as reported previously [2]. We diagnosed the lesions as trichomycosis axillaris. It has been suggested that the bacteria produce a cement-like substance that adheres to the hair [3]. Predilection sites of trichomycosis axillaris are the axilla, pubic area, scrotum and intergluteal region [2]. The main factors contributing to the pathogenesis of trichomycosis axillaris include obesity, hyperhidrosis, poor local hygiene and a moist environment [4]. Since our patient did not have these typical causes, clinicians should pay attention to such rare infectious complications in patients with SLE receiving immunosuppressive therapies.
