Cutaneous Candidiasis in the Groin: Epidemiology and Risk Factors
Prevalence and Common Sites of Groin Candidiasis
Cutaneous candidiasis frequently affects warm, moist, and creased areas of the body, with the groin being one of the most common sites involved. Studies from different regions, including India, Bangladesh, and Iran, consistently report the groin as a leading site for cutaneous fungal infections, including candidiasis, especially in both children and adults Prabhu2013Sanjeen2025Farhan2017+1 MORE. In one study, groin candidiasis accounted for 21% of all cutaneous candidiasis cases, making it the second most common form after onychomycosis .
Causative Organisms and Microbial Ecology
Candida albicans is the most frequently isolated organism in cases of cutaneous candidiasis of the groin, although other Candida species can also be involved Prabhu2013Mahmoudabadi2006. There is strong evidence that the gastrointestinal tract, particularly the rectum, serves as a reservoir for Candida albicans, which can then spread to the groin area. Individuals with groin candidiasis are significantly more likely to have Candida albicans present in the rectum compared to those without the infection .
Risk Factors and Predisposing Conditions
Several risk factors increase the likelihood of developing cutaneous candidiasis in the groin. These include increasing age, higher body weight, a family history of diabetes mellitus, and the use of systemic corticosteroids . Additional predisposing factors identified in various studies are diabetes, use of antibiotics, steroid treatment, chemotherapy, and being in the extremes of age (newborns and the elderly) . Females appear to be more frequently affected than males in some populations Farhan2017Mahmoudabadi2006.
Clinical Patterns and Diagnosis
Cutaneous candidiasis in the groin often presents as intertrigo, a rash that occurs in skin folds, and is commonly diagnosed through clinical examination, supported by microscopic examination and culture of skin scrapings . In children, candidiasis is more prevalent in those under five years old, while in adults, it is more common in women aged 21-40 years Sanjeen2025Mahmoudabadi2006.
Emerging Concerns: Candida auris
Candida auris, a multi-drug resistant yeast, has recently emerged as a significant concern, particularly in healthcare settings. The groin, along with the axilla and nares, is a primary site for C. auris colonization. This organism can persist in skin folds and is difficult to eradicate, making prevention and effective screening essential, especially in vulnerable populations .
Prevention and Management
Good skin care, especially keeping skin folds clean and dry, is crucial in preventing and managing cutaneous candidiasis in the groin. This is particularly important for individuals with diabetes and young children, who are at higher risk . Early detection and appropriate treatment are key to preventing the spread and recurrence of infection .
Conclusion
Cutaneous candidiasis in the groin is a common and significant health issue, especially in warm, humid climates and among individuals with certain risk factors. Candida albicans is the primary causative agent, with the gastrointestinal tract serving as a likely source. Prevention strategies, early diagnosis, and targeted management are essential, particularly in high-risk groups and in the context of emerging pathogens like Candida auris Lynch1969Prabhu2013Sanjeen2025+3 MORE.
