Metastatic uterine leiomyomata. A case report

Area of Science:

• Gynecologic Oncology
• Pulmonary Medicine
• Pathology

Background:

• Uterine leiomyomata are common benign tumors, but their metastasis is exceptionally rare.
• Distinguishing metastatic leiomyomata from uterine leiomyosarcoma can be challenging.
• Pulmonary involvement from uterine leiomyomata is infrequently reported in medical literature.

Observation:

• A unique case of pulmonary metastasis from a uterine leiomyoma is presented.
• The metastasis followed a prolonged clinical course of 21 years.
• Extensive, multiple pulmonary nodules were observed without associated respiratory symptoms.
• Cystic changes within the lung lesions mimicked cystic lung disease.

Findings:

• The study details an unusual case of uterine leiomyoma with pulmonary metastasis.
• The metastasis exhibited a protracted 21-year course.
• Asymptomatic, widespread pulmonary nodules with cystic degeneration were noted.
• Histopathological confirmation was crucial for diagnosis, differentiating it from malignancy.

Implications:

• This case expands the understanding of rare metastatic patterns of uterine leiomyomata.
• It underscores the importance of considering benign leiomyomata in the differential diagnosis of pulmonary nodules, even with extensive disease.
• The findings suggest that prolonged, asymptomatic pulmonary involvement is possible.
• Awareness of such rare presentations can aid in accurate diagnosis and patient management.
