“…Suspicion of erythrasma affecting unusual sites like the palm has been confirmed by Wood’s lamp examination. [ 9 ] The fluorescence may be patchy but is limited to the affected area [ Figure 2 ]. It is faintly positive in subungual erythrasma[ 8 ] or false-negative after a recent bath since porphyrins are water-soluble.…”

We describe the presentation of five adults with erythrasma, misdiagnosed as tinea and prescribed antifungal treatment which resulted in incomplete clearance. The lesions were restricted to axillary and/or inguinal folds. They were dry, brown macules with fine scaling. Except for one with moderate pruritus, they were asymptomatic. No fungal elements could be demonstrated in any of the patients in 10% KOH preparation. Gram stain revealed short gram-positive rods in varying proportions. All the patients showed a pink fluorescence on Wood’s lamp examination. After treatment with topical clindamycin singly or in combination with oral azithromycin, there was complete clearance of the lesions leaving normal-appearing skin in three and residual hyperpigmentation in one. The overdiagnosis of tinea in the ongoing epidemic of dermatophytosis is a potential concern. Wood’s lamp examination is very useful to confirm or exclude erythrasma.

“…Widespread infection may occur. [36][37][38][39][40] Various clinical manifestations of C.minutissimum, namely pitted keratolysis, erythrasma and trichobacteriosis, may co-occur in the same patient. 41 Coinfection with dermatophytes, other bacteria, and candida has been described.…”

Erythrasma is a common superficial cutaneous bacterial infection caused by Corynebacterium minutissimum, a normal inhabitant of the skin surface. Under favourable conditions, the organism invades the stratum corneum, where it multiplies and produces clinically evident lesions. Increasing age, excessive sweating, diabetes mellitus, obesity, overcrowding and immunosuppression, including HIV, are risk factors for the disease. The condition can be confused with other infectious and non-infectious skin diseases, chiefly dermatophytosis. Erythrasma clinically presents in the groin, axilla, submammary, inguinal, intergluteal cleft and web spaces between the toes. Coinfection with fungi and superinfection upon primary dermatosis are common. Erythrasma can be diagnosed with a characteristic coral-pink fluorescence with Wood‘s lamp examination. Smears, biopsy and cultures are seldom required but are useful when the Wood‘s lamp test is negative. Atypical presentations do occur and require astute clinical judgment. This condition should be distinguished from other dermatosis as treatment is different. Treatment is with topical or oral antimicrobials, depending on the site and extent of the lesions. Recurrence can occur, and methods to prevent it should be in place. Novel treatments need robust testing prior to inclusion in the therapeutic armamentarium.
