Chapter 19, Problem 1CCS
Summary Introduction
Case summary:
The given case is of Mr. H who was another victim of collision and was admitted to the hospital. His routine complete blood count revealed low levels of total leukocyte and lymphocytes. He complained of pain in his right ring finger. On examination, it was found that the right ring finger and dorsum are edematous and red streaks radiated from his right forearm.
Characters in the case:
Mr. Hutchinson, nurse, and doctor.
Adequate information:
Pain in the right ring finger.
To determine:
The indication given by the red streaks emanating from the bruised finger and the problem if there were no red streaks but right arms would be edematous.

Provide a brief description of the lymphatic system. What are its principal functions? Why is movement of lymph through the lym-phatic system very slow?
Lymphatic System
Where is the excessive fluid which leaks during diffusion collected?
Mr. X, age 57, presented to his physician with marked fatigue, nausea with occasional diarrhea, and a sore, swollen tongue. Lately, he also has been experiencing a tingling feeling in his toes and a feeling of clumsiness. Microscopic examination of a blood sample indicated a reduced number of erythrocytes, many of which are megaloblasts, and a reduced number of leukocytes, including many large, hypersegmented cells. Hemoglobin and serum levels of vitamin B12 were below normal. Additional tests confirm pernicious anemia.
Discussion Questions
1. Relate the pathophysiology of pernicious anemia to the manifestations listed above.
