The organism invades the stratum comeum where it proliferates and causes erythrasma. Erythrasma typically appears as delineated, dry, red-brown patches in intertriginous areas, such as the axilla, groin, interdigital spaces, intergluteal cleft, perianal skin, and inframammary area.
Interdigital erythrasma is more common than previously thought; in one study of 151 patients with erythrasma, the most common site was the toe webs (64.9%), followed by the inguinal region (17.9%), the axillary region (14.6%), and the inframammary region (2.6%).2 Erythrasma affects 4% of the population; risk factors include poor hygiene, hyperhidrosis, obesity, warm climate, diabetes, and an immunocompromised state.
50 cases of erythrasma were collected at random from the outpatients of Department of Dermatology in a medical college situated in South India over a period of 1 year from Jan.
Patients with clinically confirmed diagnosis of erythrasma.

is a macular brown area with few symptoms, most often found in the axillae or groin.
He singled out erythrasma
and tinea cruris as two conditions that can be mistaken for candidiasis.
However, there is another condition known as erythrasma
which looks similar but requires antibiotics to clear it up, and this may be the case here.
The differential diagnosis includes dry skin, pitted keratolysis, erythrasma
, and contact dermatitis.

6) BACTERIAL INFECTIONS(Table 5): Out of 38 patients (15.2%) with bacterial infections, septic skin conditions were present in 29 patients (11.6%) and erythrasma
in 2 patients (0.8%) followed by ENL in 1 patient (0.4%) and leprosy in 6 patients (2.4%)
