Simultaneous avulsion of the insertion of the flexor digitorum profundus tendon and a displaced intra-articular fracture of the distal phalanx occurred in a 45-year-old man. Review of the literature reveals that this is a rare injury. A case report is presented, along with a review of the literature.

Subungual squamous cell carcinoma of a nailbed secondary to chronic nail biting occurred in a 37-year-old man. This is a frequently misdiagnosed lesion. A case report is presented with a review of the literature. Malignancies of the nailbed are rare entities. Up to 1986, only 52 cases had been reported in the English literature, most of which were squamous cell carcinomas. Other reported malignancies are melanomas, subungual Bowen's disease, and basal cell carcinomas. Diagnostic confusion is common because many chronic problems of the nailbed may be clinically similar and therefore mask a squamous cell carcinoma.
A congenital arteriovenous malformation of the hand occurred in a 39-year-old woman. Review of the literature reveals that this presents a challenging therapeutic problem. A case report is presented, along with a review of the laboratory assessment and treatment options.
A traumatic venous aneurysm within the greater saphenous vein occurred in a 15-year-old hockey player. The patient had early diagnosis and surgical excision of the lesion. Venous aneurysm is a rare clinical entity and a pathologic curiosity in the absence of varicose veins. It can lead to serious complications, such as pulmonary embolism, portal hypertension, and rupture. Early diagnosis with the use of venography and surgical excision of the lesion can prevent major complications.
