This study describes the first reported case of histiocytic sarcoma in an aging female gerbil. The neoplasm primarily affected the spleen and liver, with no involvement of the reproductive organs.

Area of Science:

  • Veterinary Pathology
  • Oncology
  • Rodent Models

Background:

  • Histiocytic sarcoma is a malignant neoplasm of myeloid or histiocytic origin.
  • While documented in various species, its occurrence in gerbils is not previously reported.
  • Aging animals are more susceptible to neoplastic diseases.

Purpose of the Study:

  • To document and characterize a novel case of histiocytic sarcoma in a gerbil.
  • To describe the gross and histopathological findings of the neoplasm.
  • To compare the presentation with similar neoplasms in other species.

Main Methods:

  • Necropsy and histopathological examination of an aging female gerbil.
  • Gross examination of major organs, focusing on spleen and liver.

  • Microscopic evaluation of tissue sections stained with Hematoxylin and Eosin.

    • Main Results:

    • A histiocytic sarcoma was identified, predominantly involving the spleen and liver.
    • The spleen and liver were considered the primary sites of origin.
    • No evidence of neoplastic infiltration in the uterus or ovaries was observed.

    Conclusions:

    • This report details the first instance of histiocytic sarcoma in gerbils.
    • The spleen and liver are likely primary sites for this neoplasm in gerbils.
    • The absence of reproductive organ involvement differentiates this case from similar neoplasms in female mice.
