Study Notes
Thyroid Gland Lesion
- Three features to identify the thyroid gland as larger than normal: • Large distended follicle lined by flattened cuboidal epithelium • Proliferation of follicles, leading to an overall increase in organ size with a large amount of colloid • Increased hemorrhage • Increase in the number of thyroid gland follicle epithelium
Adenomyosis of the Uterus
- Organized edge: Endometrium
- Features of the organized edge: • Endometrium in the proliferative phase with endometrial glands containing goblet and secretory cells surrounded by lamina propria
- Normal myometrium features: • Mainly smooth muscle • Supporting connective tissue (fibroblasts, vascular tissue)
- Abnormalities in the myometrium: • Choristoma formation (endometrial gland and lamina propria are evidence) • Endometriosis
Fibroadenoma of the Female Breast
- Normal area in the breast section: • Gland embedded within a fibrocollagenous and adipose tissue
- Four abnormalities: • More glands and ducts than normal • Very dense fibrocollagenous stroma • Dilated ducts • Well-differentiated mass encapsulated by fibrous tissue (capsule formed)
Fibroleiomyoma of the Uterus
- Organized edge: Endometrium
- Features of the organized edge: • Endometrium in the secretory or early degenerative phase • Degeneration occurs
- Normal myometrium features: • Smooth muscle cells • Fibroblasts • Vascular tissue
- Abnormalities in the myometrium: • Roundish lesion shrunken away from a surrounding capsule • Irregular arrangement of smooth muscle cells
Primary Adenocarcinoma of the Female Breast
- Organized edge: Epidermis (skin)
- Deep in the breast tissue: • Basophilic region with cells growing in clumps
- Characteristics of an adenocarcinoma: • Large clumps of pale basophilic cells with dark basophilic nuclei • High nuclear-to-cytoplasmic ratio • Hyperchromasia nuclei • Basophilic cells attempting to form duct-like and gland-like structures • No capsule at the margin between normal and abnormal cells • Cells infiltrating and invading • Increased number of cells in mitosis • Surrounding stroma with degenerative changes and necrosis
Secondary Malignant Melanoma of the Brain
- Organized edge: Leptomeninges
- Abnormalities: • Arachnoid, subarachnoid space, and pia meter abnormal
- Tumor comprising melanocytes
- Characteristics of malignant melanoma: • No capsule or defined margins • Tumor cells showing hyperchromasia
- Reasons for malignancy: • Invasive, infiltration, metastasis • Multiple masses (secondary) vs. single mass (primary) • Metastasis via blood vessels is evident
Myocardial Hypertrophy
- Approximate thickness of a normal left ventricle: 1 cm
- Definition of hypertrophy: increase in cell size, leading to increased thickness and mass
- Reasons for left ventricular hypertrophy (not hyperplasia): • Increased thickness due to cell size increase • Cardiac muscle fibers are permanent in size
- Cause of this condition: hypertension
Fibroleiomyoma of the Uterus
- Degree of differentiation: Well-differentiated
- Appearance of the rounded mass: fibrous capsule
- Features indicating the lesion is benign: • Well-defined margins • Round mass • Surrounded by a capsule
