Lipomas are common benign neoplasms consisting of mature fatty tissue. They are usually of roundish or ovoid shape and are situated in a single anatomical region. They most frequently occur on the back and in the extremities. Most lipomas are subcutaneous and require no imaging evaluation. When deep, large and unusual in location, MRI can identify and localise these tumours and is the best exploration to differentiate lipoma and lipo-sarcoma. We describe a case of a patient with an intramuscular lipoma of the biceps brachii.

Failure of internal fixation of intertrochanteric fracture is associated with delayed union or malunion resulting in persistent pain and diminished function. We report a rare case of implant failure of the gamma nail with intertrochanteric fracture non union treated by DCS plate screw and bone graft.

Tumors of the biliary tract are rare, and their survival prognosis is short since diagnosis is often made at advanced stages of the disease. Diagnosis remains difficult because symptoms are often unspecific. Bone metastasis from biliary carcinoma are rare. We report a case of a humeral metastasis revealing a biliary carcinoma.

Metacarpal tuberculosis is a rare presentation of the disease; it represents only 1% of all bone sites. The following report documents the case of a 28-year-old female who sought a consultation for a painful right hand following an injury. Radiographs showed a fracture of the distal fifth metacarpal through a lytic lesion. Histology of a biopsy specimen revealed granulomas with caseous necrosis, specific to tuberculosis. The patient experienced a complete recovery with anti-tubercular treatment. This case of an unusual presentation of isolated metacarpal tuberculosis was reported with the intention of highlighting the rarity of this location. It is therefore imperative to bear in mind the possibility of such atypical presentations of tuberculosis when making a rapid and correct diagnosis and prescribing adequate treatment.
