    This study examined thirteen epithelioid sarcoma cases using microscopy and immunohistochemistry. Findings revealed characteristic tumor cell morphology and confirmed vimentin and keratin expression, aiding diagnosis.

    Area of Science:

    • Oncology
    • Pathology
    • Cancer Biology

    Context:

    • Epithelioid sarcoma is a rare soft tissue sarcoma.
    • Accurate diagnosis is crucial for effective treatment planning.

    Purpose:

    • To characterize the light microscopy (LM), ultrastructural, and immunohistochemical features of epithelioid sarcoma.
    • To discuss the diagnostic and histogenetic aspects of this rare tumor.

    Summary:

    • LM analysis of thirteen epithelioid sarcoma cases showed a nodular pattern with atypical epithelioid and spindle cells, and central necrosis.
    • Ultrastructural examination revealed abundant intermediate filaments, desmosome-like junctions, and microvilli-lined intercellular spaces.
    • Immunohistochemistry confirmed positivity for vimentin and keratin, supporting the diagnosis.
