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.
