%X Background: Itchy maceration of the toe webs is common in warm and humid weather.Some cases do not respond to treatment for tinea or eczema.Methods: Patients with foot intertrigo with a poor response to antifungal or antiinflammatorytreatment from 2004 to 2009 were included in this study. Theirgeneral characteristics were recorded. Bacterial and fungal cultures as wellas potassium hydroxide preparations were performed.Results: We recorded 32 episodes of foot bacterial intertrigo in 17 patients. The diseasewas more common in men (82%) and the mean age of the patients was59 years. The main clinical finding was maceration of the toe webs. Themajority of bacterial cultures grew mixed pathogens (93%). Pseudomonasaeruginosa, Enterococcus facealis and Staphylococcus aureus were the mostcommon pathogens. Autoeczematization was present in 50% of the 32 diseaseepisodes.Conclusion: Foot bacterial intertrigo is not a rare condition and can easily be confusedwith interdigital tinea or eczematous dermatitis. Proper identification of bacterialorganisms is critical for early effective antibiotic therapy. Patientsshould be instructed about proper foot hygiene, which is important to preventrecurrent infections.
