7,8] Smears, which do not show granuloma or
epithelioid cells and having few polymorph and necrosis in absence of Ziehl Neelsen (ZN) staining, can be misdiagnosed as acute suppurative lymphadenitis.
epithelioid cell granulomas are observed histologically in both diseases, caseation necrosis is rarely observed in GR.
Caseous necrosis along with
epithelioid cell granuloma was observed in 42 (85.
Another tumor with clear cells that may pose a diagnostic challenge with a metastatic CCRCC is that of PEComa (tumors displaying perivascular
epithelioid cell differentiation) of the pancreas.
Epithelioid AML, the second group of renal AMLs, are composed of sheets of
epithelioid cells that can behave aggressively, with the potential for metastasis and resultant adjuvant therapy.

Epithelioid cell, Pleomorphic type, with chondroid or osseous differentiation and undifferentiated type.
Histopathological examination of axillary lymph node revealed extensive effacement of architecture with numerous
epithelioid cell granulomas having central polymorphic collection and nuclear debris and scattered multinucleated giant cells (Figure 4).
7] E-AML tumours are comprised of round to polygonal
epithelioid cells with clear or granular eosinophilic cytoplasm intermixed with spindle cells, often showing varying degress of mitotic activity.
