Bullous Darier's disease mimicking Hailey-Hailey disease.

BACKGROUND

The bullous variant of Darier's disease (DD) is a rare type characterized by histological and clinical overlap with Hailey-Hailey disease (HDD).

CASE REPORTS

The following case report describes two cases of familial DD; a 51-year-old woman who presented with erythematous plaques, covered by small blisters in axillary and inguinal areas, and the first patient's daughter, who presented with keratotic papules localized on the axillary and inframammary folds.

CONCLUSION

These two cases are original by the predominant flexural distribution, and by a bullous form in the first case, clinically and histologically mimicking HHD.
