Title:
Rare case of Tinea Corporis Bullosa
Abstract:
Tinea Corporis is a superficial fungal infection of the body caused by dermatophytes of the genre Trichophyton and Microsporum. It can affect any part of the body excluding the scalp, hands, feet, groins, and nails. It is also called ringworm for the typical ring shape of lesions with central clearance. The lesions are usually well-demarcated, sharply circumscribed, oval or circular, mildly erythematous, scaly patch or plaque with a raised leading edge. Pruritus is common in most of the patients. There are different clinical variants of Tinea Corporis which resembles with other dermatological conditions and produce diagnostic dilemma. We have represented a case of Bullous Tinea Corporis, a rare clinical variants in a 48 year old female of which was characterized by vesicles or bullae, usually limited to the borders of an erythematous scaly plaque, diagnosed by microscopic visualization of organism and treated with anti-fungal drugs.
Introduction:
Tinea infections are the most common superficial fungal infections, encountered by physicians and are often caused by dermatophytes of genera Trichophyton and Microsporum. They have been named in relation to the anatomical site involved such as tinea unguium, tinea pedis, tinea cruris, tinea capities, tinea corporis etc, but may cause infection in any anatomical sites 1. Itching, centrifugally growing, erythematous rash with scaly plaques with annular shape are characteristic 2. While the tinea corporis occurs worldwide, it is mostly common in tropical regions 3. Tinea Corporis Bullosa is rare clinical variant of Tinea Corporis and is characterized by vesicles and bullae, usually limited to the borders of the erythematous scaly plaque. Rupture of the vesicles or bullae may leave behind the erosion and crusts over the erythematous background 4.
Case illustration:
A 48 year old female presented with round erythematous rashes around left flank and trunk from 5 days on the outpatient department. Both lesion started together with erythematous lesions which mild pruritus. There was no mucosal, palm, sole and nail involvement. The size gradually began increasing and slowly started scaling with raised border. On the 3 rd day patient developed vesicular eruptions which gradually increased to multiple bullae filled with clear fluid mainly concentrated on the periphery. Figure 1. Some bullae ruptured to form the crust over the lesion. The bullae easily ruptured on touching. Bullae spread and Nikolsky signs were negative.
