Clinical and Laboratory Features of Six Cases of Candida and Dermatophyte Folliculitis and a Review of Published Studies
Mycopathologia , Volume 181 - Issue 1-2 p. 97- 105
Although some studies have investigated the epidemiological characteristics of Malassezia folliculitis (MF), little is known about the clinical features and laboratory characteristics of folliculitis caused by other fungi. In this prospective study, 158 patients with folliculitis were identified, and cytological and mycological examinations were performed. The positive fungal cultures were confirmed using conventional methods, ITS sequencing and HWP1 analysis. Additionally, an in vitro antifungal susceptibility test was performed. Of 158 patients with folliculitis, 65 (41.1 %) were found to have fungal folliculitis. The most common (90.8 %) fungal folliculitis was MF. Non-MF fungal folliculitis was detected in 6 (9.2 %) patients. Four patients were diagnosed with dermatophytic folliculitis (Trichophytonrubrum in three patients and Arthroderma vanbreuseghemii in one patient), and two patients were diagnosed with Candida albicans folliculitis. Although only 5 of the 6 samples were found to be positive via a potassium hydroxide test, all May–Grünwald–Giemsa-stained samples were positive. Both of the C. albicans isolates demonstrated a susceptibility profile to itraconazole, and all four dermatophytes were susceptible to terbinafine. All six patients completely recovered with systemic and topical treatment. This study revealed that dermatophytes and C. albicans are the primary causative agents of non-Malassezia fungal folliculitis. We compared our findings with published reports on fungal folliculitis.
