  • Slide 1 - National Program of Cancer RegistriesEducation and Training Series How to Collect High Quality Cancer Surveillance Data
  • Slide 2 - NAACCR Administers NPCR-Education Contract for the Centers for Disease Control and Prevention (CDC) Awarded in _____2001 Contract Number: #200-2001-00044
  • Slide 3 - Melanoma
  • Slide 4 - Melanoma Sites include Skin (C44.0-C44.9) Vulva (C51.0-C51.2, C51.8-C51.9) Penis (C60.0-C60.2, C60.8-C60.9) Scrotum (C63.2) Accounts for approximately 4% of newly diagnosed cancers annually
  • Slide 5 - Anatomy of the Skin
  • Slide 6 - Skin Covers entire surface of body Consists of three layers Epidermis: thin outer layer Dermis: thick underlying layer Hypodermis: fatty layer
  • Slide 7 - Epidermis Consists of five sub-layers Basal cell layer Innermost layer of epidermis Contains basal cells Contains melanocytes that produce melanin Melanoma develops when melanocytes undergo malignant transformation Contains Merkel cells
  • Slide 8 - Epidermis Squamous cell layer Resides above basal layer Called stratum spinosum Contains keratinocytes Contains Langerhans cells Is the thickest part of epidermis
  • Slide 9 - Epidermis Stratum granulosum Thin granular layer Stratum lucidum Translucent layer Stratum corneum Outermost layer Sloughs off dead keratinocytes
  • Slide 10 - Sub-layers of Epidermis Image source: Merck Source - Dorland’s Illustrated Medical Dictionary
  • Slide 11 - Dermis Thickest of the three layers Main functions are: Stores much of the body’s supply of water Supplies nutrients to the epidermis Regulates body temperature
  • Slide 12 - Dermis Contains specialized cells and structures Blood vessels Lymph vessels Hair follicles Sweat glands Sebaceous glands Nerve endings Collagen
  • Slide 13 - Dermis Papillary layer Regulates body temperature Supplies epidermis with nutrient-filled blood Reticular layer Provides structure and elasticity Supports components of skin
  • Slide 14 - Hypodermis Network of fat and collagen Functions as: Shock-absorber for body Insulator Stores fat as energy reserve
  • Slide 15 - ICD-O-3 Histology Coding Melanoma
  • Slide 16 - Caution!! Pre-2007 Multiple Primary and Histology Rules used in the following slides are based on 2006 rules.
  • Slide 17 - Common Melanoma Histology Superficial spreading melanoma (8743/3) 70% of melanoma cases Nodular melanoma (8721/3) 15% of melanoma cases Acral lentiginous melanoma (8744/3) 8% of melanoma cases Lentigo maligna melanoma (8742/3) 5% of melanoma cases
  • Slide 18 - Histology Coding Rules: Melanoma Rules are a hierarchy Use rules in priority order with rule 1 having highest priority Use the first rule that applies Rules from SEER Program Coding and Staging Manual (PCSM) 2004, pages 86-87
