Study Notes
Benign vs Malignant Neoplasms
- Benign neoplasms are typically small, slowly growing, non-invasive, well-differentiated, and localized
- Malignant neoplasms can be large or small, fast-growing, invasive, poorly differentiated, and metastasize
Benign Epithelial Neoplasms
- End in "-oma" (not Carcin-, Sarc, Lymph-, or Melan-)
- Derived from epithelial tissue (ecto- or endo-)
- Types:
- Adenoma: tumor forming glands
- Papilloma: tumor with finger-like projections
- Papillary cystadenoma: papillary and cystic tumor forming glands
- Polyp: a "tumor" that projects above a mucosal surface (not a true neoplasm)
Malignant Epithelial Neoplasms
- Carcinoma: malignant epithelial neoplasm
- Types:
- Adenocarcinoma: gland-forming neoplasm that produces mucin
- Squamous cell carcinoma: keratin-producing tumor with intercellular bridges and desmosomes, expresses P40/p63 protein
- Neuroendocrine carcinoma
- Transitional type carcinoma
- Undifferentiated carcinoma
Benign Mesenchymal Neoplasms
- Derived from mesenchymal tissue (mesodermal)
- Types:
- Lipoma: fat neoplasm
- Chondroma: cartilaginous neoplasm
- Leiomyoma: smooth muscle neoplasm
- Rhabdomyoma: striated muscle neoplasm
Malignant Mesenchymal Neoplasms
- End in "-sarcoma" (not Lymph- or Melan-)
- Types:
- Liposarcoma: fat neoplasm
- Chondrosarcoma: cartilaginous neoplasm
- Leiomyosarcoma: smooth muscle neoplasm
- Rhabdomyosarcoma: striated muscle neoplasm
- Osteosarcoma: osteoid-producing/bone tumor
