Aggressive angiomyxoma, a rare soft tissue benign neoplasm, predominantly occurs in the female pelvic peritoneum and perineum region during reproductive age. It is slow growing, locally infiltrative, and has a high risk of local recurrence and the neoplastic character of blood vessels. The standard treatment is surgery. We report three unusual aggressive angiomyxoma cases. The first case was a pedunculated mass of the left labium major; the second, a left perineal mass that infiltrated into the paravesical area via the obturator foramen; and the third, a big mass in the retroperitoneal cavity, found that growing aggressive angiomyxoma looked like lava expulsion in the pelvic area. After a thorough examination and full radiologic workup, we performed surgical excision in each patient via different approaches. Histopathologic findings were consistent with diagnosis of aggressive angiomyxoma. To date, no relapse has been observed.

Symptomatic thoracic ossification of the ligamentum flavum is rare, and a modality for its treatment has not yet been fully established; most reported patients complained of myelopathy. Herein, the authors will report on an extremely rare presentation of thoracic ossification of the ligamentum flavum, along with clinical outcomes. The patient complained of chest discomfort and myelopathy symptoms for 1 year secondary to thoracic ossification of the ligamentum flavum. He underwent one surgical procedure. Postoperatively, his symptoms such as chest discomfort and myelopathy improved completely. As of this report, the patient has had a good postoperative recovery, had good overall health, and adapted well to his social activities.
