[Sequestration of the posterobasal segment of the right lower pulmonary lobe].

Pulmonary sequestration is a rare congenital malformation that receives its blood supply from a systemic artery. We report a case of pulmonary sequestration treated by ligature of the anomalous artery without pulmonary resection. Pulmonary sequestration must be treated surgically before the occurrence of severe complications.

[Tumoral calcinosis of the plantar forefoot: a case report and review of the literature].

Tumoral calcinosis of the plantar forefoot is an uncommon benign condition resulting from deposits of hydroxyapatite crystals in periarticular soft tissue. The pathogenic mechanism remains to be clarified. This condition is generally observed in young subjects and a hereditary pattern is often discovered.

[Neglected spontaneous bilateral rupture of the patellar tendon: a case report].

A patient taking corticosteroids for rheumatoid arthritis experienced a spontaneous bilateral rupture of the patellar tendon. Initially neglected, the rupture was repaired surgically by tendinoplasty using the semitendinous tendon for the right knee and inversion of the quadriceps tendon for the left. Functional results were similar.

The floating metatarsal. A rare traumatic injury.

The authors report a case of concomitant plantar Lisfranc dislocation and plantar metatarsophalangeal dislocation of the hallux. This is the second case of floating metatarsal described in the literature. When examining patients with Lisfranc joint injuries, one should explore carefully the metatarsophalangeal joints.

[Bifocal schwannoma of the sciatic nerve: a case report].

Schwannoma is a benign tumor generally observed on peripheral nerves. A sciatic localization is rare, observed in 1% of the patients. Multiple localizations have been reported in exceptional cases.
