Answer to Question 1

ANS: C
Osteoblasts can be easily confused with the plasma cell. They have an eccentric nucleus and blue cytoplasm; however, they do not have a well-defined Golgi complex (area of hof). Osteoblasts tend to be found in clusters, which is not true of normal plasma cells.

Answer to Question 2

ANS: D
The normal M:E ratio of bone marrow is 1.5:1 to 3.3:1. A ratio of 1:1 is therefore decreased, meaning that either the number of red cell precursors has increased or the number of white cell precursors has decreased. The fat-to-cell ratio assesses the overall cellularity of the marrow and should be roughly 1:1.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.
