Dermoscopy improves the diagnostic accuracy in pigmented skin lesions, but it is also useful in the evaluation of nonpigmented skin tumours as it allows the recognition of vascular structures that are not visible to the naked eye. Bowen's disease (BD) or squamous cell carcinoma in situ is usually nonpigmented, but may also rarely be pigmented. Objective To describe the dermoscopic features in a series of pigmented and nonpigmented BD. ⋯ Dermoscopy can be helpful for diagnosing BD because of the presence of repetitive morphological findings such as glomerular vessels and a scaly surface. In pigmented BD, small brown globules and/or homogeneous pigmentation can be seen as well.

Comparative Study
Human adipose tissue-derived cells delay re-epithelialization in comparison with skin fibroblasts in organotypic skin culture.
Wound healing of deep and extensive burns can induce hypertrophic scar formation. During the early steps of wound healing fibroblasts migrate into the wounded area. Fibroblastic cells present in tissues other than dermis may also migrate into the wounded area and participate in the wound healing process. ⋯ The possibility of generating HSEs with different cell types represents an attractive approach for in vitro studies focusing on the mechanism of wound healing.
