Benign metastasic pulmonary leiomyoma

Benign metastatic leiomyoma is a rare lung tumor. There are just over 200 cases of this disease reported in the global literature. This article presents a clinical observation by the authors, describing a case of multiple leiomyomas located in the lungs of a young woman who had previously undergone a supravaginal hysterectomy due to a similar tumor. Case Description: Patient R., 42 years old. Five years ago, the patient underwent surgical treatment in the form of a supravaginal hysterectomy for myoma. There was no history of malignant diseases. During a routine examination, computed tomography of the chest revealed multiple solid lesions in the lungs. Comprehensive examinations, including esophagogastroscopy, fiber colonoscopy, fiber bronchoscopy, and positron emission tomography, did not reveal other tumor pathologies (besides the lung lesions). For morphological study of the tumor foci, a thoracoscopic atypical resection of the lower lobe of the left lung was performed. Histological conclusion: benign metastatic leiomyoma of the lung. No malignant tumor growth was found in the examined material. Conclusion: Benign metastatic pulmonary leiomyoma is a rare tumor that lacks distinct criteria for reliable preoperative differential diagnosis. Benign metastatic leiomyomas occur predominantly in women with uterine leiomyoma, especially after surgical treatment for this pathology, although isolated cases of this disease in men have been reported. Typically, multiple solid foci are detected in the lungs during radiological examination.
