17. What could be the Provisional Diagnosis???

18.  Hb – 14g/dl
 Total Count- 9300
 Platelet Count- 2,60,000
 Peripheral Smear – N
 ESR -14
 SERUM Creatitine – 0.7
 Na/K – 128/5.3
 Ca- 9.3
 LDH – 179
 TSH & PT/INR - N

19.  X ray Chest – Right paracardiac
consolidation with Right sided Pleural
Effusion with loculated component along
lateral chest wall.
 2D ECHO done was Normal.
 CT Chest done outside was reviewed here
again which showed Calcified Anterior
Mediastinal Mass Measuring 8.7 X 6.8 X 6.7
cm.

20.  USG guided Pleural fluid tapping was done
and analysis revealed its Exudative effusion.
 CT guided Biopsy done and Histopathology
report sent revealed Features suggestive of
Thymoma and Type A according to WHO
Classification.

21. Any Questions ???

24. The most commonly used
staging system for thymoma is
called the Masaoka system

26.  Thymoma
 Lymphoma
 Germ cell tumor
 Thyroid and Parathyroid tumor

27.  A neoplasm of the Thymic epithelial cells .
 Results from dysregualtion of the proliferation
and maturation of T- lymphocytes .
 This process results in either Autoimmunity or
Immune defeciency
 As a result , thymomas are associated with
autoimmune diseases in 70% of the patients
during diagnosis .
 Thymomas are ussually encapsulated and
spread by local extension .

28.  30 % local symptoms
 30 % abnormal chest radiographs
 30 % Myasthenia Gravis (paraneoplastic
syndrome)

29.  Local symptoms :
Dyspnea .
Dysphagia .
Cough .
SVC obstruction .
 Thymomas tend to be highly vascular →
bleeding and necrosis .
 Paraneoplastic :
MG.
Hypogammaglobulenemia .
Good syndrome .
Oppurtunistic infections

30.  CBC- anemia, thrombocytopenia,
granulocytopenia (in pure red cell aplasia)
 Peripheral smear study
 Quantitative immunoglobulin assay to r/o
immunodeficiency
 Anti ACh receptor antibodies/repititive
nerve stimulation tests/Edraphonium
ameliorative tests to r/o myasthenia gravis
 Bone marrow aspiration to r/o pure red cell
aplasia
