Which peristomal skin complication is caused by a fungal infection?

• A. Bacterial infection
• B. Candidiasis
• C. Otitis
• D. Psoriasis

Answer: (B)

Fungal infections around the stoma are candidiasis, caused by Candida species such as Candida albicans. Yeast thrives in the warm, moist environment under the appliance, leading to a red, moist peristomal area often with satellite lesions beyond the main irritated zone. This color and pattern—moist red dermatitis with extending satellite spots—helps distinguish it from bacterial infection, psoriasis, or otitis, which have different presentations. Management includes improving skin dryness and barrier integrity, ensuring a proper appliance fit to reduce leakage, and applying a topical antifungal as prescribed, with attention to contributing factors like moisture and occlusion to prevent recurrence.
