  • Variation in color and/or an increase in diameter, height, or asymmetry of borders of a pigmented lesion are noted by the majority of patients with melanoma. (medscape.com)
  • Primary cutaneous melanoma may develop in association with precursor melanocytic nevi (ie, common, congenital, and atypical/dysplastic types), although more than 70% of cases are believed to arise de novo (ie, not from a preexisting pigmented lesion). (medscape.com)
  • The lesion consists of proliferating melanocytes and keratinocytes, which result in large pigment-containing dendritic cells. (medscape.com)
  • Surgery is the primary mode of therapy for localized cutaneous melanoma. (medscape.com)

  • In this study, we evaluated the ability of four different NCT (NiFe2O4, CoFe2O4', Ni and Co3O4') to initiate oxidative stress, induce redox-sensitive transcription factors and trigger inflammatory response in primary human epidermal keratinocytes (HEK) and melanocytes (HEM). (cdc.gov)
  • This has overlooked the keratinocyte microenvironment of primary melanomas. (ascopost.com)
  • This layer ranges in thickness from 15-100 or more cells depending on anatomic location and is the primary protective barrier from the external environment. (medscape.com)

  • The intracellular reactive oxygen species (ROS) scavenging activity and antioxidation-related gene expression of the callus extract were evaluated in both Hs68 fibroblast cells and HaCaT keratinocytes. (springeropen.com)
  • Obvious intracellular ROS scavenging activity of the extract was detected in both Hs68 and HaCaT cells with 64.30 ± 8.27% and 32.50 ± 4.05% reduction at the concentration of 250 μg/mL. (springeropen.com)
  • The models tested included melanoma cells, neonatal melanocytes and keratinocytes, and immortalized HaCaT keratinocytes. (biologists.com)
