Giant melanoma of the left thumb

A 74-year-old female patient is described with a giant melanoma of the left thenar and concomitant bilateral pulmonary metastases. Palliative treatment consisted of a two-staged procedure in order to save the limb from amputation. Firstly, perfusion with gamma-interferon, tumour necrosis factor-alpha and melphalan was carried out, after which the tumour had been reduced to one third of its initial volume. Secondly excision of the tumour and coverage of the wound with a split skin graft was done. Remarkably, the extent of the multiple pulmonary metastases was temporary and diminished 1 month after perfusion, although no systemic leakage could be determined during the procedure. The management strategy is discussed with emphasis on this indication for limb perfusion

Extended vertical transatrial septal approach for the removal of left atrial myxoma

Objective: Optimal exposure greatly facilitates left atrial myxomectomy and is mandatory for safe and efficacious tumour removal. The purpose of this study was to evaluate one institutions experience, with an alternative to the classical approach, for the removal of left atrial myxoma. Methods: In an eight-year period, eight patients underwent surgical removal of left atrial myxoma at our institution using the extended vertical transatrial septal approach, slightly modified compared to the original method of Guiraudon and associates, as the septum was initially incised superiorly instead of through the fossa ovalis. Results: One patient with poor left ventricular function died shortly after the surgical procedure because of low cardiac output. Postoperative course of the other patients was uneventful. No rethoracotomy for bleeding was carried out and no permanent arrhythmias were seen. There was one late death at 4.5 months after operation, for which no clear reason was found. Mean follow-up was 55 months (range 1 to 79 months) and revealed six asymptomatic healthy patients. Conclusions: We feel that the extended vertical transatrial septal approach provides good exposure of left atrial tumours and facilitates complete surgical removal without inherent complications such as tumour cell dissemination or fragmentation.
