A

Inflammation of the tonsils (sore throat)-Tonsils are lymph nodes in back of the mouth and nose, they filter out bacteria and infectious microorganisms

17
Q

Tonsillitis Symptoms

A

-Difficulty swallowing-Sore Throat lasting longer than 48 hours-Tenderness of the jaw and throat-Voice change, loss of voice-Ear pain-Fever, Chills-Headaches

18
Q

Lymphatic Neoplasms

A

Most are MALIGNANT, called Lymphomas or Lymphosarcoma.Most common are Hodgkins Lymphoma and Non-Hodgkins Lymphoma

19
Q

Hodgkin’s Lymphoma - Cause

A

-virus or genetic predisposition-age 24 - 40, most common in males-specific cancer cells (REED STERNBERG CELLS, B-Lymphocytes)

20
Q

Hodgkins Lymphoma Symptoms

A

NAME?

21
Q

Hodgkins Lymphoma outcome

A

-Cancerous lymph nodes or tissues becoming hard and calcified ->spreads to lung, spleen and lining of intestine-some disfigurement-20% mortality rate-life expectancy is 2 - 10 years

22
Q

Non-Hodgkins Lymphoma

A

-Spreads faster than Hodgkins due to immunosuppressive meds.-B and T Lymphocytes-Age 40 - 55, more males-25% 5 year survival rate-spreads to lungs, breast and stomach

23
Q

Spleen

A

Lymphatic Organ-removes bloodborne antigens-removal and destruction of aged or defective blood cells

24
Q

Splenomegaly cause and symptoms

A

Enlargement of the spleen-Caused by trauma or injury to ribs or abdomen on left side, infection (Mononucleosis, salmonella, virus), neoplasms (leukemia)-Symptoms are tenderness, pain, discomfort and ANEMIA.-Danger of rupturing or hemorrhaging of the spleen

25
Q

Hypersplenism

A

Overactive Spleen -Filters out too many red blood cells -> increased destruction amenia

26
Q

Thymus

A

NAME?

27
Q

Malignant Thymoma

A

Cancer of the Thymus-Occurs in young adults-metastasizes slowly, if at all-Causes swelling in the neck-Easily diagnosed and surgically removed

28
Q
