Squamous cell carcinoma is the most common maligne primary tumour of the hand. It is almost always located on the dorsum of the hand, an occurrence in the palm is very rare. Usually these tumours are recognised early because of their clinical presentation and visible location. We report on a case in which the patient presented in our hospital only due to a massive mechanical impairment of his hand function through an oversized squamous cell carcinoma. On the basis of this case the therapeutic algorithm for large squamous cell carcinoma in the palm is illustrated and discussed., (© Georg Thieme Verlag KG Stuttgart · New York.)

The triangular fibrocartilage complex (TFCC) represents an important anatomical structure interposed between the ulnar carpus and the distal ulnar. Injuries and degenerative changes of the TFCC are of high clinical relevance and there are numerous treatment options available based on different concepts and which are being used to varying extents. The aim of this systematic review was to evaluate the effectiveness of different therapies for lesions of the TFCC. Studies on TFCC lesions were systematically reviewed, classified into evidence levels and selected according to predefined criteria. A total of 259 publications were identified as being potentially relevant and finally 35 studies could be included in the review. In addition, a survey was performed among German hand surgeons in order to identify commonly used procedures for TFCC lesions in Germany. The classification of Palmer is mostly used both in the literature and in Germany and therapeutic decisions are predominantly based on this classification. The systematic review revealed some common treatment strategies for traumatic and degenerative lesions. Generally, the level of evidence was poor for all identified publications. For this reason, evidence-based recommendations for the treatment of TFCC lesions could not be derived from the literature. There was broad consent between the results of the literature review and the survey.

Congenital venous malformations (VM) at the hand are rare. VM consist of dysplastic venous vessels without progressive cellular proliferation. The therapy for VM is considerably different from that for vascular tumours (e. g., haemangiomas). Treatment options for vascular malformations are antithrombotic medication, local compression, resection of the VM, and obliteration of the lumina by percutaneous sclerosation. Here, the percutaneous sclerosation for the treatment of VM with sodium tetradecyl sulfate has been illustrated and discussed on the basis of 2 case reports., (© Georg Thieme Verlag KG Stuttgart · New York.)
