Diffuse chronic granulomatous mucocutaneous candidiasis

Area of Science:

• Immunology
• Infectious Diseases
• Pediatrics

Background:

• Chronic mucocutaneous candidiasis (CMC) is a rare disorder characterized by persistent or recurrent mucosal and skin infections with Candida species.
• It is often associated with a defect in cell-mediated immunity and can present with other autoimmune or endocrine complications.
• Adrenal insufficiency is a known comorbidity in some patients with CMC.

Observation:

• A 3-year-old Thai boy presented with diffuse chronic granulomatous mucocutaneous candidiasis.
• He also had recurrent bacterial skin infections and adrenal insufficiency.
• Candida albicans was identified within dermal granulomas, indicating a fungal etiology for the skin lesions.

Findings:

• The patient exhibited a defect in cell-mediated immunity and was also diagnosed with anemia.
• Initial treatment with topical clotrimazole, oral iron, systemic antibiotics, and low-dose prednisone showed a significant clinical response.
• Despite the positive response to treatment, the patient unfortunately died due to disseminated cryptococcosis.

Implications:

• This case highlights the complex interplay between fungal infections, immune defects, and endocrine dysfunction in pediatric patients.
• It underscores the potential for opportunistic infections like cryptococcosis in immunocompromised individuals, even with apparent clinical improvement.
• Management of such cases requires a multidisciplinary approach, addressing both the primary immune defect and secondary infections.
