Cases J. 2009 Sep 8:2:8673. doi: 10.1186/1757-1626-0002-0000008673.


Introduction: Primary leiomyoma of the lung is a rare benign tumor that usually presents as a solitary lesion predominantly in young females. Fewer than 100 cases have been reported. Common symptoms include fever, chronic cough, hemoptysis, chest pain, shortness of breath, and pneumonias.

Case presentation: A 34-year-old, non-smoker female who presented with recurrent pneumonias. She was found to have a primary leiomyoma of the right middle lobe. This was treated by right middle lobectomy. 6-month follow up showed patient doing well without evidence of residual disease on computerized tomography.

Conclusion: Primary pulmonary leiomyoma is a rare tumor distinct from benign metastasizing leiomyoma. Histologic features include absence of mitotic count, low cellularity, lack of cytologic atypia and pleomorphism. Treatment is by conservative surgical resection and carries a favorable prognosis.
