AI Article Synopsis

  • The case involves a 52-year-old woman with fast-growing chest tumors initially deemed suspicious for malignancy.
  • Chest CT scans revealed well-defined cystic tumors, leading to video-assisted thoracic surgery for further examination.
  • Pathological analysis confirmed the diagnosis of benign metastasizing leiomyoma, highlighting the importance of thorough examination to distinguish between benign and malignant cystic tumors.

Article Abstract

We herein report a rare case of fast-growing benign metastasizing leiomyoma. A 52-year-old woman was admitted to our hospital with abnormal chest shadows. Chest computed tomography showed well-circumscribed cystic tumors. Because malignancy could not be completely distinguished in fast-growing tumors, video-assisted thoracic surgery was performed. The pathological findings revealed many cysts and the proliferation of smooth muscle cells. According to the Stanford criteria, the tumor was diagnosed as benign metastasizing leiomyoma. One possible reason for the fast growth of the tumor was enlargement of the cysts. Malignant diseases characterized by cystic tumors are rare but occasionally reported. Therefore, differentiation by a pathological examination is essential.

Oncocytic carcinoma is a rare malignant neoplasm of oncocytic cells, such cells being characterized by abundant granular eosinophilic cytoplasm, invasive growth, and pronounced cellular pleomorphism. It may arise de novo, or through malignant transformation of a pre-existing benign oncocytoma. Oncocytic carcinoma most commonly occurs in the salivary glands, with rare involvement of the ocular adnexa where it mainly affects caruncle, conjunctiva, and lacrimal sac, and only very arises in the lacrimal gland.
