Pirfenidone increases the epithelialization rate of skin graft donor sites.

Background: Improving epithelialization of donor sites of split-thickness skin grafts (STSG) is extremely important in burned patients. We aimed to assess the efficacy of pirfenidone, a drug with anti-inflammatory, antifibrotic, and antioxidant effects, to accelerate wound healing. We hypothesized that pirfenidone accelerates the epithelialization rates in donor sites.

Case for diagnosis. A bluish nodule on the scalp.

Acrospiroma, also known as hidradenoma, is a rare cutaneous tumor that has several histological characteristics. As a consequence, a high index of suspicion is necessary for its diagnosis. Here we report a case that illustrates the importance of a good clinical-pathologic correlation in order to recognize this disease.

An Atrophic Plaque with Arborizing Vessels.

Dermatofibromas are a common finding in the daily clinical practice. Most lesions are found incidentally or because patients seek medical attention due to the aspect of the lesion. Rare variants of dermatofibroma such as aneurismatic or atrophic dermatofibroma can be encountered simultaneously; thus, these combined features may raise the possibility of other diagnoses to be considered.
