Renal Leiomyosarcoma. A Report of Two Cases

Area of Science:

• Oncology
• Pathology

Background:

• Leiomyosarcoma is a rare cancer.
• Renal leiomyosarcoma is exceptionally uncommon.

Observation:

• Two cases of kidney leiomyosarcoma are presented.
• Patients were a 63-year-old female and a 53-year-old male.
• Tumors exhibited characteristic smooth muscle actin and desmin positivity.

Findings:

• Immunohistochemical analysis revealed specific smooth muscle markers.
• Patients experienced notable survival periods of 10 and 20 months.
• Comparison with literature data was performed.

Implications:

• These findings contribute to understanding rare renal malignancies.
• The observed survival suggests potential therapeutic responses.
• Further research into renal leiomyosarcoma is warranted.
