Overview
Erythrasma must be differentiated from other dermatological conditions that present with reddish-brown scales and itching, as well as other diseases resulting from corynebacteria infection.
Differentiating Erythrasma from other Diseases
Erythrasma must be differentiated from other dermatological conditions that present with reddish-brown scales and itching, as well as other diseases resulting from corynebacteria infection.
| Disease | Findings |
|---|---|
| Psoriasis | Presents with erythema and formation of silvery scales on the epidermis, resulting in itching and pain.[1] Differentiates from Erythrasma in that it is usually located throughout the entire body; Erythrasma usually manifests in skin folds of the armpit, groin, and perianal regions.[2]Psoriasis is an autoimmune disorder and is not caused by Corynebacteria; therapeutic options include topical corticosteroids, systemic anti-inflammatory therapies (such as methotrexate and cyclosporine), and UVA/UVB phototherapy.[2] Psoriasis is a chronic, recurrent condition; Erythrasma will usually resolve with sufficient treatment. |
| Dermatophytosis | Presents with lesions that vary based on the location of the mycosis, but usually displays in a circular shape with erythema, scaling, and itching at the point of infiltration .[3] Differentiated by its mycotic cause. Visually distinct from Erythrasma by consistently forming circular-shaped "ring" lesions. Treatment involves topical antifungal medication, including miconazole, clotrimazole, ketoconazole, terbinafine, naftifine, and butenafine.[4] |
| Skin Candidiasis | Presents with rash that displays erythema and itching, as well as folliculitis.[5] Differentiated from Erythrasma in that it is caused by Candida fungal infection. While Erythrasma usually manifests in moist locations, such as skin folds, skin candidiasis is usually found in wet or dry regions of the body. Treatment includes antifungal therapy, including fluconazole, caspofungin, micafungin, anidulafungin, and additional topical and systemic options.[6] |
| Intertrigo | An inflammatory condition of the epidermis caused by repeated friction between adjacent skin folds.[7]. Presents with erythema, itching, and scaling in primarily moist regions of the body. Differentiates from Erythrasma in that it can progress to discharge and pain if untreated.[8] Can be caused by bacterial or mycotic infection, as well as a non-infectious inflammatory response to moisture and friction. Treatment varies based on the cause; it is important to differentiate Erythrasma from Intertrigo due to the former's singular cause as Corynebacterium minitissium to determine appropriate therapy. |
| Contact dermatitis | An inflammatory condition of the epidermis resulting from direct contact with an allergen or irritant. Contact dermatitis is similar to Erythrasma due to the usual presentation of erythema and itching. It differentiates from Erythrasma by manifesting with blisters, pain, and discharge. Differentiated from Erythrasma by its cause: an allergic response by contact to a specific surface or entity. There is no indication of bacterial infection. Common causes include chemicals from cosmetic and hygienic products, fabrics, metals, and animal hair or skin. Therapy involves avoiding the original cause and application of topical or oral corticosteroids and analgesics.[9] |
| Seborrheic dermatitis | Presents with erythema and white-yellow scaling skin that sheds, accompanied by pruritus and flaking. Is primarily found in the face, upper chest, and retro-auricular area. Similarly to erythrasma, it can affect skin folds, including the axillae and the genitals.[10] It is differentiated from erythrasma by its varied causes; seborrheic dermatitis causes are not fully known and are speculated to be autoimmunal, neurological, or from nutrition deficiency.[11] Therapy focuses on treating the inflammation, including corticosteroids, or topical antifungal medication if a mycotic causes is determined.[12] |
