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 .

• Cytological features of malignancy• Necrosis (N) of the tumor related to ischaemia.

• Organ: myometrium• Lesion: benign neoplasm of the uterine smooth
muscle (L) surrounded by normal myometrium.• Diagnosis: Leiomyoma .

• Organ: myometrium ( higher magnification)• Lesion: tumor margin well circumscribed and no
evidence of local invasion and their is pseudocapsule (C).

• 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.

• organ: Breast ( higher magnification)• Lesion: hyperchromatic malignant cells can be
seen infiltrating the surrounding adipose tissue.• Diagnosis: malignant neoplasm of Breast.

• 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.

• Organ: Colon
• Lesion: mitosis are seen and nuclear hyperchromatism
and higher nuclear to cytoplasmic ratio.• Diagnosis: Adenocarcinoma ( well Differentiated )

• 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.
