Discussion:
Tinea corporis bullosa is rare presenation of tinea and can be mistaken for a variety of dermatoses such as bullous phemigoid, erythema multiformie, bullous allergic contact dermatitis and linerar IgA bullous dermatosis 5. The common causative agents for Tinea corposris bullosa are Tinea rubrum, Microsporum Canis, Trichophyton schoenleinii. 5-7. Misdiagonosis and treatment delays are common. But in our case, pruritic nature of lesion, contact history with cattles, annular shape of lesion with scaling and central clearing raised the early suspicion for tinea corporis bullosa. But exclusion of other common causes of blistering skin condition is must. The mechanism of bulla formation is inflammatory response due to dermatophyte leading to hypersensitivity reactions provoked by presence of dermatophyte antigen, which might be implicated in bulla formation accompained by dermal infiltrate 7. Treatment is similar to treatment of tinea corporis and lesion usually resolves within 1-2 months. Recurrance is common.
Conclusion:
Bulla formation in tinea corporis is rare but should be considered in patient after excluding other blistering dermatologic conditions. It is important to be aware about unusal presentation and should be considered in acute infections without past history and family history of blistering skin infections.
