[Pseudo-tumor digital tuberculosis: A case report and review of the literature]. / Tuberculose osseuse digitale pseudotumorale : un cas et revue de la littérature.

We report a case of a 66-year-old woman, who was treated for a circumferential tumefaction of the middle phalanx of the third finger, evolving for one year. The excision-biopsy of the phalanx led to the diagnosis of an osseous tuberculosis. Through this exceptional case, the authors made a review of the literature on the clinical, radiological and evolutionary aspects of the digital osseous tuberculosis.

[Intramuscular hemangioma of the forearm: seven cases]. / Les hémangiomes intramusculaires de l'avant-bras: sept cas.

The authors reexamined the files of seven patients dealt with for intramuscular hemangioma of forearm. It concerns five women and two men, between 16 and 39 years old. The average time of consultation was 13 months. The clinical signs were dominated by the development of a generally painless soft mass over the anterior compartment of the forearm and/or the elbow. Two patients presented nervous lesions signs of the ulnar or median nerves. The feeder pedicle was the ulnar artery in five cases and radial artery in two cases. The excision was incomplete in two cases because of the invasion of the ulnar nerve by the hemangioma. With four years average follow-up, the five patients having undergone a complete excision do not present a recurrence and the hand function is excellent. The authors insist on the interest of a preoperative diagnosis with the IRM, which permits to envisage surgical difficulties due to the proximity of vascular and nervous pedicles.

[Hemangioma of the clavicle: report of one case]. / Hémangiome osseux de la clavicule (à propos d'un cas).

We present a case of intraclavicular hemangioma with a description of its clinical, radiological and histological features and its differential diagnosis regarding other bony tumors.

[Hibernoma of the thigh]. / Hibernome de la cuisse.

Hibernoma is a rare benign tumour of brown fat. It presents as a voluminous slow-growing mass in the regions where remnants of brown fat can remain in adults. We report a case of a hibernoma on the thigh and present the diagnostic and therapeutic elements of this type of tumour, whose differential diagnosis of liposarcoma.

[Giant lipoma of the hand: case report and literature review]. / Lipome géant de la main : présentation d'un cas clinique et revue de la littérature.

Giant lipoma of the hand is rare. The diagnosis is based on a clinical tumor and acroparesthesia from compression of the median and ulnar nerves. The MRI is the best exam to study local extension. Fibrolipoma of the median nerve and low-grade liposarcoma are the principal differential diagnoses.

[Myositis ossificans circumscripta of the forearm]. / Myosite ossifiante circonscrite de l'avant-bras.

Myositis ossificans circumscripta is a benign lesion characterized by focal heterotopic soft tissue ossification and occurring in young people generally after localized trauma. The location of this case in the forearm is rare. The clinical signs, radiological appearance and the histological features can be confused with osseous or soft tissue sarcoma, as was the case in our patient.

[Aneurysmal bone cyst of the ulna]. / Kyste osseux anévrismal de l'ulna.

Aneurysmal bone cyst (ABC) accounts for 1 to 4 percent of primary bone tumours. There is a distinct predominance in the 10- to 20-year age group, and it is rare after age 50. Despite its benign character, it is sometimes locally aggressive, and can attain significant size. This was so in the case we report of a patient with an ABC of the ulna.
