    The microRNA landscape of cutaneous squamous cell carcinoma

    Cutaneous squamous cell carcinoma (cSCC) is a keratinocyte-derived skin tumor. It is the second-most-common cancer affecting the Caucasian population and is responsible for >20% of all skin-cancer-related deaths. The estimated incidence of non-melanoma skin cancer in the USA is >1000000 cases per year, of which roughly 20-30% are squamous cell carcinoma. To better understand and treat this challenging cancer, current research focuses on development of novel strategies to improve the understanding of tumor biogenesis on an individual basis. microRNAs are becoming important biomarkers in the diagnosis, prognosis and treatment of cSCC. This review describes the current knowledge on miRNA expression in cSCC and its role as a biomarker for personalized medicine

    Metazoan gastrointestinal endoparasites were recovered from 10 of 14 (71.4%) gray foxes [Urocyon cinereoargenteus (Schreber, 1775)] collected in New Mexico from 1996 -1998. They include a pentastome Porocephalus sp., (n=1, 7.1%), a trematode: Fasciola hepatica Linnaeus, 1758 (n=1, 7.1%), the nematodes: Physaloptera rara Hall and Wigdor, 1918 (n=3, 14.3%), Physaloptera praeputialis Linstow, 1899 (n=2, 14.3%), an unidentified female Physaloptera sp. (n=1, 7.1%), Toxocara mystax (Zeder, 1800) (n=2, 14.3%), Toxocara canis (Werner, 1782) (n=1, 7.1%), Spirocerca lupi (Rudolphi, 1809) (n=6, 42.9%), and cestodes: Taenia pisiformis (Bloch, 1780) n=3, n=3, (21.4%), Taenia serialis (Gervais, 1847) (n=3, 21.4%), and Mesocestoides kirbyi Chandler, 1944 (n=7, 50%). All parasites found are new records for the gray fox in New Mexico. The parasites, Porocephalus sp, Fasciola hepatica, Toxocara mystax and Mesocestoides kirbyi are new records for the gray fox for North America

    Histopathologic spectrum of morphea

    No full text
    Morphea is an autoimmune skin disease with protean clinical manifestations. Histologic features are similarly variable, and skin biopsies may be nondiagnostic. A single-institution retrospective cohort study was conducted. Morphea patients who had a biopsy in 2005-2015 were included, and a histopathological review was conducted by 2 pathologists. There were 51 biopsy specimens from 40 subjects. The most common histologic features were dermal sclerosis (90%), dermal thickening (78%), collagen homogenization (86%), a superficial and deep infiltrate (76%), a moderate-abundant inflammatory infiltrate (73%), and periadnexal fat loss/decreased skin appendages (71%). Twenty-four specimens were not diagnostic of morphea. In these specimens, the main clues to diagnosis included the presence of dermal sclerosis (79%), subtle collagen homogenization (75%), dermal thickening (58%), moderate-to-abundant plasma cells (50%), and perineural inflammation (50%). There were no statistically significant differences between active and inactive lesions, nor untreated and treated lesions. The histopathologic features of morphea are variable and a high proportion of biopsies are not diagnostic. Clinicians and pathologists should have a high degree of suspicion to correctly make the diagnosis of morphea
