Laboratory Studies
- When a patient presents with cutaneous manifestations of CMC, the following studies should be performed:
- Scrapings from the infected site are suspended in 10-20% KOH and microscopically examined. The presence of yeast cells and pseudohyphae confirms the diagnosis. Fungal stains, such as chlorazol black E stain or Parker blue-black ink, may be added to highlight the organism.
- Candidal organisms grow well on several culture media. They grow as yeasts on Sabouraud agar with chloramphenicol and cycloheximide. C albicans also grows on dermatophyte test medium but does not demonstrate the red color change characteristic of dermatophytes.
- Screening laboratory tests for a CMC-associated endocrine dysfunction include blood glucose or glycosylated hemoglobin testing, thyroid function tests, liver functions tests, serum electrolyte evaluation, corticotropin testing, and serum cortisol values. Consider a complete blood cell count, to screen for leukopenia, and an HIV test. Other endocrine screening tests that may be considered include follicle-stimulating hormone, luteinizing hormone, prolactin, testosterone, parathyroid-stimulating hormone, calcium, phosphate, magnesium, and short synacthen test. Perform baseline and yearly follow-up tests to screen for associated endocrinopathy.
Other Tests
- Results from cellular immunity tests, such as the prick-test with Candida antigens, may be negative. In vitro lymphocyte proliferation is usually reduced for C albicans extracts.
- Immunoglobulin G subclass deficiencies have been reported in some patients with CMC, who have a predisposition toward respiratory tract infections. Isolated immunoglobulin A and immunoglobulin M deficiencies have also been reported, in addition to a single case of complete agammaglobulinemia.[9]
- In patients with other recurrent infections, immune studies should be considered.
- If the clinical suspicion for APECED is high, genetic analysis of the AIRE gene can be confirmatory.[6, 7]
- Recently, anti-interferon-1 antibodies were found to be highly specific for APECED and to precede the appearance of CMC, suggesting an important new diagnostic test.[10]
Procedures
- A skin biopsy is rarely needed to make a diagnosis of Candida infection, but it may be performed to rule out the possibility of superinfection of a primary dermatosis. A periodic acid-Schiff stain can confirm the presence of pseudohyphae. Nutritional deficiencies with cutaneous manifestations should also be considered.
Histologic Findings
Routine hematoxylin and eosin–stained sections of superficial candidiasis lesions reveal subcorneal pustules. Granulomatous lesions of CMC show hyperkeratosis and parakeratosis, with a dense mixed dermal infiltrate containing lymphocytes and plasma cells. Periodic acid-Schiff or silver stains of skin biopsy specimens can help identify organisms in the stratum corneum and dermis.
