Background: Angiomatoid fibrous histiocytoma [AFH] is a rare soft tissue tumor most commonly occurring in children, adolescents, and young adults. It is considered to be a tumor of intermediate malignancy because of its less aggressive course. The extremities are the most common site of involvement, followed by the trunk and head and neck.

Background: Peritrochanteric fractures of the femur rank among the most severe fractures in elderly people. The Gamma Nail is one of the latest advance in the treatment of trochanteric fractures based on intramedullary nailing principles during closed procedures. This paper is made to assess the efficacy of closed intramedullary osteosynthesis with a gamma nail in the treatment of peritrochanteric fractures depending on the type of fracture and patient age.

Background: upper extremity stress fractures are infrequent events in tennis sport. According to our literature, we have only identified 6 case reports of upper limb stress fractures among amateur or professional tennis players. To the best of our knowledge, this is the only case report where stress fractures occur in: hamate, triquetrum, 2nd, 4th, and 5th metacarpal bones simultaneously. Case presentation: 27 years old lady, presented with acute burning pain at the base of her right thumb. There was not a history of direct trauma. Her symptoms start to appear after 3 days of playing tennis. Physical examination was negative for tenderness, swelling and erythema. The rheumatoid factor was elevated (20.3 iu/ml). the diagnosis of multiple stress fractures was made by the suggestive MRI findings. Conclusion: Although stress fractures of the upper limbs are not common, it is of a great value to keep the clinical suspicion high towards it. Especially in amateur or professional athletes with persistent or worsening symptoms. The best modality to confirm such fractures is MRI.
