Primary hyperparathyroidism revealed by a pathological fracture is very uncommon. We present a case of a 54-year-old female patient who was admitted with fracture of her right femur. She underwent closed intramedullary reconstruction nailing with bipolar locking. The pathological findings confirmed the diagnosis of primary hyperparathyroidism with brown tumor. Further tests showed increased both calcium level and PTH level. A parathyroidectomy was performed. She made an uneventful recovery and was discharged to home.
RESUMEN
BACKGROUND: Mixed mullerian tumours are uncommon endometrial neoplasms that are composed by a combination of mesencymal elements and epithelial elements. They own their denomination to the mullerian origin of their components wich derive from the paramesonephric ducts. According to the benignity or the malignity of each component, four types of mixed mullerian tumours are individualised. Adenosarcoma is composed of benign glandular elements and sarcomatous, usually low-grade, stromal elements. AIM: We report a case of an endometrial adenosarcoma in a 59-year-old woman. Clinicopathological caracteristics and the etiopathogeny of this uncommun neoplasm will be discussed. CASE: A 59-year-old women complained metrorrhagia assearated pair since three months. Vaginal examination showed an incresed valure. Copathological U.S and abdominer CT showed an important. No ather turner were detected hysterrchomy with dilated annexetny werre performed. Pathological examan concluded to tummor with animation of mesenchynal and le pthel elements

UNLABELLED: Gastrointestinal stromal tumor (GIST) is a new distinct entity defined as CDI 17 or c-kit positive mesenchymal tumors, originaling in gastrointestinal pacemaker cells known as interstitial cells of Cajal. This study evaluate the percentage of GIST previously diagnosed as mesenchymal tumors in our hospital during 11 years. METHODS: A total of 30 surgically resected gastrointestinal tumor specimens were collected from January 1990 to December 2000 in the pathology laboratory of la Rabta Jospital. Immunohistochemical studies were performed on these tumors with antibodies of CD 117, smooth muscle actin (SMA) and protein S-100. RESULTS: Among the 30 tumors, 26 (86.6%) were CD117 positive and were classified as gastrointestinal stromal tumors. Among the 26 GIST, SMA was positive in 11 tumors (42.3%), 6 tumors (23%) expressed protein S-100. The 4 tumors classified as non-GIST were leiomyomas with the following immunohistochemical characteristics: CD117-negative with strong SMA-positive and protein S100 negative status. CONCLUSIONS: The majority (86.6%) of mesenchymal gastrointestinal tumors were GIST, except for a smalls groups of smooth muscle tumors.
