Bowen's disease is generally regarded as premalignant dermatoses. The disease affects both skin and the mucosa and has the potential to progress to invasive squamous cell carcinoma. There are descriptions of several histological variants of Bowen's disease like psoriasiform, atrophic, pagetoid, etc. Acantholysis of anaplastic keratinocytes with bullae/cleft formation is described in premalignant condition like actinic keratosis and adenoid variant of squamous cell carcinoma, but there is lack of report describing this phenomena in Bowen's disease. We present a case of unusual acantholytic variant of Bowen's disease with focus of micro-invasive carcinoma.
