Bone Marrow Biopsy Results - December

Here they are...

Raw, with no commentary from me. Heh.

Clinical Diagnosis: MGUS


BONE MARROW ASPIRATE REPORT

Megakaryocytes : Present
Blasts : 1%

Others : -; Touch prep also examined
M:E ratio : 2.4:1

INTERPRETATION:

Maturing trilineage hematopoiesis with 1% plasma cells.
See biopsy, flow cytometry and cytogenetics for definitive evaluation of plasma
cell population.

Pathologist:   *************, M.D.

CLINICAL DATA:
Clinical History: 29 year-old woman with history of MGUS
Clinical Diagnosis: None given.


RESULT:

FLOW CYTOMETRY REPORT -- MYELOMA PANEL

Gating is by CD38 and CD138 on plasma cells with <1% of the total cells in the
gate.

T cell % Positive B cell % Positive Myeloid/Others % Positive
-----------------------------------------------------------------------
CD3 CD19 1 CD45
CD5 CD38+CD138+ 74 CD34
CD3+CD4+ CD19+CD5+ CD14
CD3+CD8+ CD38+CD56+ HLA-DR
CD3+CD7+ CD138+CD56+ 2 CD33

CD56 9 CytoKappa+ 26 CD15
CD57 CytoLambda+ 78 CD64
CD3+94+ CD19+CD52+ Glycophorin
-----------------------------------------------------------------------

INTERPRETATION:
Flow cytometric analysis of this bone marrow aspirate reveals a minute
population of plasma cells that is positive for CD38 and CD138, negative for
CD56, and shows apparent cytoplasmic lambda light chain staining, HIGHLY
SUSPICIOUS FOR INVOLVEMENT BY A PLASMA CELL NEOPLASM. Correlation with
morphologic findings (BS-12-56932) is required for further evaluation.

These tests were developed and their performance characteristics determined by
the Hematology Laboratory, Brigham and Women's Hospital. They have not been
cleared or approved by the U.S. Food and Drug Administration. The FDA has
determined that such clearance or approval is not necessary.

Type: Surgical Pathology
Specimen Type: Bone marrow biopsy

PATHOLOGIC DIAGNOSIS:

BONE MARROW BIOPSY:

MOST CONSISTENT WITH INVOLVEMENT BY A PLASMA CELL NEOPLASM (see NOTE)

Hemorrhagic moderately hypercellular marrow (20% fat/80% cellular).
Approximately 10% of the cellularity (5% of intertrabecular space) is comprised
of plasma cells that occur singly and in small clusters.
Immunoperoxidase and in-situ hybridization studies performed on paraffin
sections reveal that the CD138-positive plasma cells express excess lambda
light chain over kappa light chains.
Of the remaining cellularity:
Erythroid elements are present in normal proportion and exhibit maturation.
Myeloid elements are present in normal proportion, exhibit maturation and
include increased number of early and eosinophilic forms.
Blasts comprise less than 5% of the marrow cellularity.
Bone trabeculae exhibit focal osteoblastic and focal osteoclastic activity.
Giemsa stains were examined.
The aspirate smear findings are of a cellular, spicular smear showing maturing
trilineage hematopoiesis with mildly increased number of plasma cells.
Blasts are not increased.

Bone Marrow aspirate reading at DFCI (BL**********):
Differential count:
Cellularity : OK/Increased. Spicules present
Megakaryocytes : Present
Blasts : 1%
Promyelocytes : -
Myeloid : 62%
Erythroid : 25%
Lymphocytes : 11%
Plasma cells : 1%; rare binucleate forms
Others : -; Touch prep also examined
M:E ratio : 2.4:1
Maturing trilineage hematopoiesis with 1% plasma cells.
Flow cytometric analysis performed at BWH (*********, 12/10/2012) showed a
minute population of plasma cells that is positive for CD38 and CD138, negative
for CD56, and shows apparent cytoplasmic lambda light chain staining, HIGHLY
SUSPICIOUS FOR INVOLVEMENT BY A PLASMA CELL NEOPLASM.
NOTE:
The overall findings are a moderately hypercellular marrow showing maturing
trilineage hematopoiesis and 10% plasma cells with excess lambda light chain;
focal osteoclastic activity is present. Although definitive light chain
restriction is not observed by in-situ hybridizations studies, in light of IgG
lambda monoclonal gammopathy, the overall findings are MOST CONSISTENT WITH
INVOLVEMENT BY A PLASMA CELL NEOPLASM. Correlation with clinical, laboratory,
cytogenetic, and radiologic findings is recommended for further classification.



(Clinical: 29 year-old female with history of monoclonal gammopathy of
undetermined significance)

CLINICAL DATA:
History: 29 year-old female with history of monoclonal gammopathy of
undetermined significance.
Operation: Bone marrow biopsy.

TISSUE SUBMITTED:
A/1. Bone marrow biopsy.

GROSS DESCRIPTION:
The specimen, labeled with the patient's name, unit number and "PRI", consists
of a tan core of tissue, measuring 1.3 cm in length x 0.2 cm in diameter. It
is fixed in Bouin's solution and briefly decalcified in RapidCal-Immuno for 15
minutes. A Wright-Giemsa stained bone marrow aspirate smear is received.

Micro A1: Bone marrow biopsy, ESS, 1 frag, 1 cass.

CASE NUMBER: 56932.

I will say I am happy to see these numbers are a bit lower than in July.

However, there is some language that is different than my other biopsy results such as rare binucleate forms and focal osteoblastic and focal osteoclastic activity.

I meet with Dr. R this afternoon so we'll see. :)

  1. I am impressed at the diagnostic details but I am too new at all of this to know exactly what it all means; intending the words 'rare' and 'osteoclastic' are not as scary as they sound.

    1. It's all greek to me. :) Plasma cells in rare binucleated forms bascially means not very nice plasma cells. Not really sure about osteoblastic and osteoclastic activity...

  2. I'm 15 years old. I was born with HIV my mother passed away because of the HIV infection And I regret why i never met Dr Itua he could have cured my mum for me because as a single mother it was very hard for my mother I came across Dr itua healing words online about how he cure different disease in different races diseases like HIV/Aids Herpes,Parkison,Asthma,Copd,Epilepsy,Shingles,Cold Sore,Infertility, Chronic Fatigues Syndrome,Fibromyalgia,Love Spell,Prostate Cancer,Lung Cancer,Breast Cancer,Blood Cancer,Colo-Rectal Cancer,Love Spell,Weak Erection,Breast Enlargment,Penis Enlargment,Hpv,Diabetes Hepatitis even Cancer I was so excited but frighten at same time because I haven't come across such thing article online then I contacted Dr Itua on Mail drituaherbalcenter@gmail.com/ info@drituaherbalcenter.com. I also chat with him on what's app +2348149277967 he tells me how it works then I tell him I want to proceed I paid him so swiftly Colorado post office I receive my herbal medicine within 4/5 working days he gave me guild lines to follow and here am I living healthy again can imagine how god use men to manifest his works am I writing in all articles online to spread the god work of Dr Itua Herbal Medicine,He's a Great Man.
