title: It's on the tip of my tongue.
abstract: A 48-year-old white woman was admitted to the hospital with low-grade fever, night sweats, fatigue, nonproductive cough with dyspnea, bilateral knee pain, and swelling that progressed slowly over 6 weeks. She was a 30-pack-year smoker, and had received outpatient antibiotic therapy with clarithromycin and then cephalexin without improvement. The admission chest radiograph showed bilateral interstitial infiltrates, and an effusion was seen on knee radiographs. She was treated with levofloxacin, cefepime, and methylprednisolone with some improvement, but fevers persisted up to 104 degrees F/40 degrees C. She also developed multiple painful skin nodules (Figure 1) and an enlarging painful tongue ulcer (Figure 2). Her bilateral knee swelling and pain also worsened, and a bone scan showed increased activity. Skin biopsy showed acute and chronic inflammation with an abscess that contained "yeast" (Figure 3). Fungal culture from the skin lesion and joint fluid aspirate grew Blastomyces dermatitidis. Urine antigen and blood antigen enzyme-linked immunoassays for B. dermatitidis were positive. The patient was started on a 6-month course of itraconazole oral solution with slow resolution of her joint inflammation and skin lesions over the next several weeks.
