Primary extrahepatic hydatid cyst of the thigh, an unusual presentation of sciatica: A case report of a diagnostic challenge.

Introduction: Sciatica, a condition characterized by pain along the sciatic nerve distribution, is commonly associated with nerve compression or irritation. However, its etiology can vary, including rare non-spinal causes such as hydatid cysts. We present a case of hydatid cyst in the thigh causing sciatica-like symptoms, highlighting the diagnostic challenges and management approach.

Solitary bone plasmacytoma of the axis, a rare and challenging case with good outcomes.

Introduction: Plasmacytoma is a rare hematological malignancy with a more favorable prognosis than multiple myeloma. This case report focuses on a unique solitary bone plasmacytoma (SBP) at the craniovertebral junction (CVJ), managed through surgery and radiotherapy.

Case Presentation: A 50-year-old patient presented with four months of worsening neck pain and cervicobrachial neuralgia.

Conservative surgical management of surface osteosarcoma using 3D printing technology: An unusual case report and literature review.

Introduction And Importance: Surface osteosarcoma, a rare variant of osteosarcoma, poses unique challenges in diagnosis and treatment. This report discusses the application of 3D printing technology in the surgical management of a complex case involving a 27-year-old female patient with surface osteosarcoma in the proximal tibia.

Case Presentation: A 27-year-old female patient presented with a progressively growing mass on her right knee, initially misdiagnosed as a benign bone tumor.

Giant cell tumor of the tendon sheath of the toe: case report of an unusual localization.

Introduction And Importance: The purpose of this study is to highlight a rare entity of unusual location and to report our therapeutic attitude in this regard, while detailing the diagnostic criteria and therapeutic management.

Case Presentation: We describe the case of a 32 years old woman with a swelling of the big toe initially neglected by the patient, the evolution is marked by a discomfort when wearing shoes, it was a firm mass of 2 cm slightly painful without local inflammatory signs with bone lysis on radiography, The MRI showed an invasion of the flexor and extensor tendons of the hallux, our approach was a carcinological tumor exeresis and arthrodesis while preserving the toe since the pedicle was not invaded, the histological examination confirmed the diagnosis and the evolution is good without tumor recurrence.

Clinical Discussion: A giant cell tumor of the tendon sheaths (GCTTC) usually presents as a firm slow growing mass, the radiological assessment shows bone erosions, an MRI for extension assessment and histological confirmation are mandatory, malignant degenerations are unusual but should always be investigated, treatment is based on the most complete surgical resection to avoid the risk of recurrence, adjuvant radiotherapy can be done in case of incomplete resection but it is a controversial subject.

Knee tuberculosis: A misleading clinical entity (case report).

Introduction: Bone and joint infections are rare localizations of tuberculosis, and its diagnosis is challenging. The atypical clinical presentation may lead to delayed diagnosis and severe complications.

Case Presentation: We report the case of a 72-year-old female diagnosed with tuberculosis of the knee.
