  ABSTRACT: Ovarian leiomyoma is a rare benign tumor that accounts for 0.5 to 1% of all benign ovarian tumors. It probably arises from smooth muscle cells in the ovarian hilar blood vessels but there are other possible origins including cells in the ovarian ligament, smooth muscle cells or multipotential cells in the ovarian stroma, undifferentiated germ cells, or cortical smooth muscle metaplasia. Additionally, smooth muscle metaplasia of endometriotic stroma, smooth muscle present in mature cystic teratomas, and smooth muscle in the walls of mucinous cystic tumor may explain their occurrence in the ovary in some cases. A 31-year-old woman was admitted to our surgical emergency service with a one-day history of appendicitis-like symptoms. Upon laparotomy, there was a solid, oval left-sided ovarian tumor located behind the uterus. The tumor was sent to the pathology department. A diagnosis of primary ovarian leiomyoma associated with an endometriotic cyst was established. The origin of ovarian leiomyoma is still unresolved. In our case, the tumor probably arose from smooth muscle cells derived from myofibroblasts that originate from metaplastic ovarian stromal cells present in the rim of the endometriotic cyst. Despite its rarity, ovarian leiomyoma should be considered in the differential diagnosis of ovarian spindle cell tumors. Appropriate diagnosis may require additional immunohistochemical analysis in some cases.

  ABSTRACT: The purpose of the present study was to evaluate and compare the long-term results of operative treatment of a multifragment fracture of the inferior patellar pole by basket plate osteosynthesis and partial patellectomy. We retrospectively studied two groups of patients who had operative treatment of a multifragment fracture of the inferior patellar pole between 1988 and 2004. Seventy-one patients who had osteosynthesis by basket plate (Group 1) and 49 patients who had partial patellectomy (Group 2) were followed for an average of 5.3 years. The final evaluation was based on the modified Cincinnati Knee rating system test. The results were excellent or good in 90.1% patients of Group 1, and 73.5% patients of Group 2. Significant differences between the groups were noted with regard to knee pain, swallowing, level activity, compression pain, range of motion, muscular atrophy, muscular strength, and final patellofemoral score which confirms statistical analysis. The stability of the osteosynthesis by basket plate allows osseous consolidation of the fracture and permits immediate mobilization and early weight bearing. Osteosynthesis by basket plate can provide better clinical results.
