Histologically it consists of relatively monomorphic ovoid or epithelioid cells
with clear to eosinophilic cytoplasm arranged in sheets and papillary or alveolar architectures, with variable numbers of CD68-positive osteoclast-like giant cells.
Group-2: Epithelioid cell
clusters with or without Langhan's giant cells with necrotic material
Histopathology of skin biopsy from lower back showed thinned out flattened epidermis; periadnexal, perivascular and perineural circumscribed epithelioid cell
granulomas and Langhan type giant cells with collection of foamy histiocytes in the dermis (Figure 3).
After histopathology tumour type depending on morphology like Spindle cell, Round cell, Epithelioid cell
, Pleomorphic type, with chondroid or osseus differentiation and undifferentiated type.
(1-3) Because the aforementioned lesions can be entirely or partially composed of clear to eosinophilic epithelioid cells
with a tendency to aggregate around vessels, it was proposed that they might originate from a peculiar muscle cell that expresses melanocyte-associated immunomarkers, that is, the perivascular epithelioid cell
For metastatic CCRCC to the pancreas, the differential diagnoses include ductal adenocarcinoma with clear cell appearance (clear cell carcinoma), clear cell endocrine pancreatic tumor, solid serous adenoma of the pancreas, clear cell variant of solid pseudopapillary tumor of the pancreas, and perivascular epithelioid cell
* Cohesive epithelioid cell
granuloma or lymphocytic cell collection.
Tuberculous lymphadenitis was categorized into patterns namely only caseous, caseous with epithelioid cell
granuloma, only epithelioid granuloma without caseous necrosis and suppurative.
