Pathology lab neoplasia 2

  1. 1. Cytological features of malignancy Lesion : Remarkable variation in cell size and shape (Cellular polymorphism )and nuclear size and shape (nuclear polymorphism ) mitotic figures (M) and nuclear hyperchromatism.
  2. 2. • Cytological features of malignancy • Necrosis (N) of the tumor related to ischaemia.
  3. 3. • Organ: myometrium • Lesion: benign neoplasm of the uterine smooth muscle (L) surrounded by normal myometrium. • Diagnosis: Leiomyoma .
  4. 4. • Organ: myometrium ( higher magnification) • Lesion: tumor margin well circumscribed and no evidence of local invasion and their is pseudocapsule (C).
  5. 5. • organ: Breast • Lesion: the neoplasm has an irregular outline and the neoplastic cells invading the fatty tissue and collagenous stroma of the breast. • Diagnosis: malignant neoplasm of Breast.
  6. 6. • organ: Breast ( higher magnification) • Lesion: hyperchromatic malignant cells can be seen infiltrating the surrounding adipose tissue. • Diagnosis: malignant neoplasm of Breast.
  7. 7. • Lesion: the cells are commonly arranged in broad sheets and large nests (N) , formation of keratin* known as dyskeratosis (D), and forms lamellated pink-stained masses known as keratin pearls (KP). • Squamous cell Carcinoma.
  8. 8. • Organ: Colon • Lesion: mitosis are seen and nuclear hyperchromatism and higher nuclear to cytoplasmic ratio. • Diagnosis: Adenocarcinoma ( well Differentiated )
  9. 9. • Organ: Connective tissue • Lesion: Consist of various combination of spindle cells (S) ,cells resembling histiocytes (H) with pale foamy cytoplasm and malignant giant cells (G) mitotic figures are plentiful. • Diagnosis: Malignant Fibrous Histiocytoma.
