Area of Science:

  • Veterinary Medicine
  • Endocrinology
  • Oncology

Background:

  • Virilizing features in female animals can indicate underlying endocrine disorders.
  • Ovarian tumors are a potential cause of hormone imbalances and associated clinical signs.

Observation:

  • A six-year-old spayed female domestic shorthair cat presented with virilizing features.
  • Elevated serum testosterone concentration was noted prior to surgical intervention.

Findings:

  • Surgical removal of a left ovarian stump mass led to the resolution of clinical signs.
  • Histopathology confirmed the mass as a testosterone-producing thecoma.
  • Post-operative normalization of serum testosterone confirmed the tumor's hormonal activity.

Implications:

  • This case underscores the importance of considering ovarian thecomas in the differential diagnosis of virilism in female cats.
  • Successful surgical management of thecomas can reverse hormonal abnormalities and clinical manifestations.
  • Further literature review on feline thecomas is warranted to understand their prevalence and behavior.
