    Alveolar adenoma is a rare benign lung tumor characterized by well-defined nodules and typically affects individuals aged 40 to 60.

  • 2

    The tumor is composed of well-differentiated cuboidal or flattened alveolar epithelial cells and a spindle cell stroma.

  • 3

    Immunohistochemical analysis showed strong CD34 expression in stromal cells across all cases, with CD10 positivity in about two-thirds.

  • 4

    The tumors were asymptomatic in the reported cases, with no signs of recurrence or metastasis during follow-up periods.

  • 5

    Further research is needed to explore the nature of alveolar adenoma, particularly through molecular testing of the stromal component.
