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.
