Abstract
As with human species, recent studies also suggest a photoinduced etiopathology for non-epithelial cutaneous tumors in feline species. We report a recent case of a ten-year-old male cat with a white-hair coat and mesenchymal neoplasms of both auricles. Cytology, complete blood count (CBC), serum biochemistry and imaging examinations were performed. After surgery, the samples underwent routinary histopathology and were additionally stained with orcein. A routine analysis yielded values within a normal range and the imaging examination showed no abnormalities, suggesting that the bilateral presentation of neoplasms was primary rather than metastatic. The cytology was inconclusive, but, through histopathology, two well-differentiated fibrosarcomas were diagnosed and histopathological changes related to chronic UV exposure (such as epidermal hyperplasia, stratification disorders, keratinocyte dysplasia and an accumulation of elastotic material) were documented in the skin adjacent to the lesions. An orcein stain succeeded in highlighting elastosis. The elastic fibers lost their regular structure and orientation and appeared to be fragmented, wavy to branched and knotted. A morphometric analysis showed that the amount of elastotic material in the dermis close to the tumors was more than double compared with the more distant areas. Elastosis is considered to be a hallmark of photodamage; thus, an involvement of UV rays in the carcinogenic process of the tumors may be suspected.

Abstract
Photoaged skin exhibits signs of inflammation, DNA damage and changes in morphology that are visible at the macroscopic and microscopic levels. Photoaging also affects the extracellular matrix (ECM) including hyaluronan (HA), the main polysaccharide component thereof. HA is a structurally simple but biologically complex molecule that serves as a water-retaining component and provides both a scaffold for a number of the proteins of the ECM and the ligand for cellular receptors. The study provides an overview of the literature concerning the changes in HA amount, size and metabolism, and the potential role of HA in photoaging. We also suggest novel HA contributions to photoaging based on our knowledge of the role of HA in other pathological processes, including the senescence and inflammation-triggered ECM reorganization. Moreover, we discuss potential direct or indirect intervention to mitigate photoaging that targets the hyaluronan metabolism, as well as supplementation.

Abstract
Cutaneous elastofibroma is part of the connective tissue nevus complex. Two subungual cases remotely similar to the one presented here have been described before. This patient presented with an unusual form of subungual elastofibroma of the big toe, which was surgically removed. Histopathology revealed a connective tissue tumor extremely rich in very fine elastic fibers. Their relationship to oxytalan and elaunin fibers is discussed as is the potential association of this nail bed lesion with the onychodermis.

Tranexamic Acid Cream Protects Ultraviolet B-induced Photoaging in Balb/c Mice Skin by Increasing Mitochondrial Markers: Changes Lead to Improvement of Histological Appearance. Photochem Photobiol 2019; 96:863-869. [PMID: 31788813 DOI: 10.1111/php.13189] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2019] [Accepted: 11/02/2019] [Indexed: 12/12/2022]
Abstract
Tranexamic acid (TSA) is widely used as an antiaging treatment for reducing melasma and wrinkles. There are various mechanisms for wrinkle formation, and one of them is due to damage of the mitochondria. Research on mitochondria in the skin is very limited, so we are interested to see the changes that occur after application of TSA cream. We explored the effect of TSA on mitochondrial protein levels (PGC1α, Tom20, COX IV), which had affected to skin histological structure. Thirty male, 6-week-old, Balb/C mice were divided into five groups (negative control, positive control, TSA 3%, TSA 4% and TSA 5%). After 10 days of acclimatization, four groups of mice were exposed to UVB light, of which three groups were given TSA cream for 10 weeks. The skin tissue was excised for protein and histological studies. H&E staining was performed for evaluating histological changes in epidermal thickness and dermal elastosis. TSA treatment on the mice skin increased mitochondrial marker levels and epidermal thickness while decreasing dermal elastosis for all the treatment groups. Topical application of TSA significantly increased mitochondrial biogenesis which may cause alteration in epidermal thickness and reduced dermal elastosis in the histology of mice skin.
