Pathology: Exam 2, Unit 7

Cellular Alterations

Permanent cellular changes triggered by adverse conditions

Neoplastic

New growth

Dysplasia

Abnormal development of tissue; altered size, shape, and organization of cells; usually follows hyperplasia

Metaplasia

Replacement of one type of tissue into a form that is not normally found there

Neoplasm

(tumor) The abnormal, excessive, and uncontrolled multiplication of cells with the formation of a mass or new growth of tissue

Benign

oma" (lipoma)

Malignant

carcinoma" or "sarcoma

Epithelial Tissue

Group of closely packed cells that cover surfaces, line body cavities, and form secretory parts of glands

Adenoma

A neoplasm formed by glandular epithelium

Papilloma

Circumscribed overgrowth or hypertrophy of the papillae of a cutaneous or mucous surface; caused by HPV

Nevus

Circumscribed vascular tumor of the skin or other body organs due to hyperplasia of the blood vessels

Polyp

Growth or mass of tissue that protrudes from a mucous membrane

Connective Tissue

Loosely arranged cells and fibers that have nerve and blood supply; they connect, support, protect, transport, and insulate

Osteoma

Bone tumor

Chondroma

Cartilage tumor

Lipoma

Adipose tissue tumor

Angioma

Blood vessel or lymph vessel tumor

Hemangioma

Benign blood vascular tissue

Hematoma

Tumor like swelling filled with blood

Fibroma

Fibrous, encapsulated tissue; irregular in shape, firm consistency

Mastoid Osteomoa

Grows from mastoid process process producing and external swelling

Lipoblastoma

Uncommon, usually recurrent benign tumor of embryonic adipose tissue that occurs predominantly in children; on the extremities and neck

Chondroma of Auricle

Painless, slowly growing, solid tumor that distorts shape of tissue; resembles a cauliflower ear

Muscle Tissue

Highly vascular tissue that allows movement of body parts and materials through tubes

Rhabdomyoma

Striated (skeletal and cardiac) muscle tissue tumor; usually infants and young children, heart disorders

Leiomyoma

Smooth muscle tissue tumor

Nervous Tissue

Form processes, recognize environmental changes, drives responses

Neuroma

Tumor composed of nerve cells

Malignant Neoplasm

Cancer

Carcinoma

(epithelioma) Malignant growth/tumor arising from epithelium

Melanoma

A malignant pigmented mole; arises from melanocytes

Squamous Cell Carcinoma

Tumor of epidermal squamous cells

Basal Cell Carcinoma

Tumor of the basal cells of epidermis

Adenocarcinoma

Arising from glandular organ

Transitional Cell Carcinoma

Tumor of the urinary system

Sarcoma

Tumor arising from connective tissue

Osteosarcoma

MN bone tumor

Chondrosarcoma

MN cartilage tumor

Liposarcoma

MN adipose tissue tumor

Angiosarcoma

MN tumor of vascular endothelial cells

Fibrosarcoma

MN tumor formed by fibrous tissue

Lymphoma

MN tumor of lymphatic system that arise in the lymph nodes or in other lymphoid tissue

Leukemia

MN tumor of blood forming structures/organs

Rhabdomyosarcoma

MN tumor of striated muscle tissue

Leiomyosarcoma

MN tumor of smooth muscle tissue

Glioma

MN tumor of neuroglial cells

Cachexia

Sever form of malnutrition; physical wasting with loss of weight and muscle mass caused by chronic progressive disease

Cysts

Sacs within or on the body surface containing air or fluid

Ovarian Cyst

Benign, fluid filled sacs on or near the ovary

Physiologic Ovarian Cyst

Forming on normally functioning ovaries, most common, may become very large; have to be removed

Neoplastic Ovarian Cyst

Abnormal ovarian cyst type not related to function

Dyspareunia

Pain during sexual intercourse

Sebaceous Cyst

Sebaceous gland that produces sebum becomes blocked and sebum collects under the skin

Baker Cyst

(popliteal) Fluid filled cyst that causes a bulge and a feeling of tightness behind your knee

Ganglion Cysts

Noncancerous lumps that most commonly develop along the tendons or joints of wrists, hand, ankles or feet; typically round or oval and are filled with a jelly like fluid

Chalazion

A bacterial infection of the oil glands causing formation of a cyst
