What's new in dermoscopy of Bowen's disease: two new dermoscopic signs and its differential diagnosis

Abstract

Background

Clinical and dermoscopic features of Bowen's disease (BD) show great diversity. Some lesions of BD are often difficult to be differentiated from seborrheic keratosis, actinic keratosis, lichen planus-like keratosis, etc. It is necessary to fully describe the dermoscopic features of the disease, considering differential diagnosis.

Objective

To describe the dermoscopic feautres of Bowen's disease and summarize the dermoscopic differential diagnosis of the disease.

Patients and methods

Altogether 146 lesions with a histopathological diagnosis of Bowen's disease were consecutively included in this study. All the lesions were imaged with dermoscopy and analyzed for dermoscopic features.

Results

A total of 146 lesions were analyzed. The dermoscopic features most frequently observed in our series of lesions were scales (78.8%), glomerular vessels (69.2%), yellow crusts (56.8%), focal hemorrhage (55.5%), focal/multifocal hypopigmentation (44.5%), and linear irregular vessels (42.5%). Besides, we found two new dermoscopic signs in BD: the double-edge sign (30.1%) and the clusters of brown structureless areas (38.4%).

Conclusion

Bowen's disease presents a variety of dermoscopic features. The recognition of two new dermoscopic signs of BD and fully understanding its dermoscopic features will help us in differential diagnosis.
