If Kappa or Lambda is predominant and CD5 is co-expressed with CD19 (CD19/CD5 dual positive lymphocyte population), and CD23 is expressed, chronic lymphocytic leukemia is a probable diagnosis. CD19 is normally found on normal B cell populations and CD5 is normally found on mature T cell populations.
However, CD5 is present on B cells in B-chronic lymphocytic leukemia or Mantle Cell Lymphoma, both abnormal B cell malignant processes.
CD23 expression is not consistent with Mantel cells as shown on the decision tree on the right.
A monoclonal B-cell population (Kappa or Lambda predominant) with expression of CD19, CD20, CD23, and co-expression of CD5 is consistent with which of the following?

The organisms in this image are demonstrating a gram-variable phenomenon. For the most part, the organisms are staining primarily gram-negative, however, on the tips of some of the rods, there is a gram-positive staining morphology. This can be defined as gram-variable.
Which of the following best describes the organisms seen in this illustration:
Which of the following best describes the organisms seen in this illustration:
정답: D
The correct answer is Trichophyton rubrum. The tiny microconidia are lined up in a "birds on the fence" arrangement along the hyphal strand transversing the field of view (yellow arrows). Two pencil-shaped, smooth walled macroconidia are also seen in the lower left field of view (red arrows).
Trichophyton verrucosum may produce microconidia in small quantities. However, they are irregularly arranged with little tendency to line up along the hyphae. Antler hyphae and string bean macroconidia are characteristic of this species.
One of the key characteristics in the identification of Epidermophyton floccosum is the inability of this dermatophyte to produce microconidia. Two to four-celled, club-shaped macroconidia are produced, usually in clusters of two or three.
The profusion of tiny microconidia lining up along the hyphae in this photomicrograph is characteristic of which of the following organisms?

Amniotic fluid bilirubin is increased in association with the severity of hemolytic diseases of the newborn. As red blood cells lyse during these conditions, bilirubin builds up as a byproduct of the red cell destruction. The more red blood cells that are being destroyed in the baby, the more increased the bilirubin level will become.
Which one of the following tests BEST correlates with the severity of hemolytic disease of the newborn (HDN).
Which one of the following tests BEST correlates with the severity of hemolytic disease of the newborn (HDN).

Twelve weeks after onset of the disease, patients with uncomplicated acute hepatitis B usually will demonstrate which of the following in their serum?
정답: D
In an evacuated tube, blood flow into the tube depends on:

정답: A
Type I hyperlipoproteinemia is a form of hyperlipoproteinemia associated with deficiencies of lipoprotein lipase. Hyperlipoproteinemia type II is the most common form and is classified into type IIa and type IIb, depending on whether there is elevation in the triglyceride level in addition to LDL cholesterol.
Hyperlipoproteinemia type III is associated with high chylomicrons and IDL. Hyperlipoproteinemia type IV is assoicated with high triglycerides. It is also known as hypertriglyceridemia. Hyperlipoproteinemia type V is similar to type I, but with high VLDL in addition to chylomicrons.
An obese adult with premature arteriosclerosis is seen in the clinic. When her serum is tested no chylomicrons are present, LDL are normal and VLDL are increased. There is an increase in triglycerides and slight increase in cholesterol. Lipoprotein electrophoresis reveals a heavy pre-beta band. She has no skin rash and uric acid is increased. This patient has a hyperlipoproteinemia with the MOST likely type of:

정답: A
Osteoblasts are generally seen in clusters while plasma cells are often more diffusely distributed. Osteoblasts have delicate cytoplasm, whereas plasma cells have dense basophilic cytoplasm with a perinuclear halo.

The red blood cell distribution width (RDW) increases as the severity of alpha thalassemia increases because of changing MCV as the bone marrow produces smaller cells. In addition, if Hemoglobin H bodies are present, they result in the formation of schiztocytes (RBC fragments) that can have an effect on the MCV and RDW.
The Red cell Distribution Width (RDW) in alpha thalassemia is
The Red cell Distribution Width (RDW) in alpha thalassemia is
정답: D
In combined fiscal years 2005 through 2009, transfusion-related acute lung injury (TRALI) caused the higest number of reported fatalities (48%), followed by hemolytic transfusion reactions (26%) due to non-ABO (16%) and ABO (10%) incompatibilities. Complications of microbial infection, transfusion-associated circulatory overload (TACO), and anaphylactic reactions each accounted for a smaller number of reported fatalities.
정답: B
The production of long, tapered phialides is one of the key identifying features of Trichoderma species. In contrast, Penicillium species, produce phialides with blunt ends.
The phialides of Beauveria species are geniculate, forming a zig-zag pattern.
