Introduction: Aplasia cutis congenita (ACC) is a rare congenital abnormality characterized by the absence of a portion of skin at birth which most commonly involves the scalp and can affect the galea, the pericranium, the bone, and the dura mater. It can be an isolated condition or associated with other disorders.
Case Report: We present a case of ACC with a large defect of the scalp and the underlying bone treated with the use of Integra® Dermal regeneration template. At 5 months of follow-up, the wound is completely healed and the bony defect greatly reduced. Contraction of the area of alopecia was observed.
Discussion: Several surgical and conservative options have been described to treat this congenital condition: advanced dressing, skin graft, local flaps, free flaps, and other methods. In our case, we used Integra® Dermal templates which provide a barrier for infections, promote cellular activity for a rapid vascularization, and improve healing.

Decorin (DCN) is a member of the small leucine-rich proteoglycan family within the extracellular matrix, playing a role in the growth and development of hair follicle (HF). Exosomes serve as significant mediators of intercellular communication and are involved in the cyclic regeneration of HF. Exosomes derived from dermal papilla cells (DPC-Exos) are essential for the cycling and regrowth of HF.

Indoor dust can adsorb various pollutants and long-term deposition can significantly impact air quality and human health. This study investigated the occurrence, source apportionment, and health risks associated with polycyclic aromatic hydrocarbons (PAHs) and their derivatives (d-PAHs) in indoor dust, by focusing on residential and public buildings in Nanjing, China. The concentration of 16 PAHs and 27 d-PAHs ranged from 511 to 5472 ng/g and from 422 to 2904 ng/g, with the most abundant compounds being fluoranthene and 1,2-benz[a]anthraquinone, respectively.

Background: Acral lesions may represent the best/only skin lesions to biopsy in patients suspected to have dermatomyositis (DM). However, histopathologic features of acral DM skin lesions are poorly characterized.
Methods: We reviewed 50 acral biopsies from 46 DM patients and assessed numerous histopathologic features.

Burn wounds are challenging to treat due to considerable tissue damage and fluid loss. Creating wound dressings from natural and biological materials makes it possible to treat wounds and promote rapid epithelialization to speed healing and restore skin function. As a result, the ability of a collagen scaffold (Col) made from rainbow trout (Oncorhynchus mykiss) and putative bioactive phytochemical components from a Sargassum glaucescens (S.

Acute myeloid leukemia is a cancer involving uncontrolled proliferation of hematopoietic cells. Cutaneous involvement is referred to as leukemia cutis (LC). The histopathologic presentation of LC is variable, and may present with perivascular, periadnexal, dermal, or subcutaneous infiltrate.
