[Thumb Reconstruction after Oncological Resection of a Rare Aggressive Digital Papillary Adenocarcinoma: A Case Report].

We present the case of a 44-year-old female with an aggressive digital papillary adenocarcinoma of the right thumb. Aggressive digital papillary adenocarcinomas are rare tumours originating from sweat glands of the skin on the hand or foot. The tumour was located at the extensor side and had been excised in 2 operations after diagnosis as an eccine hidradenoma, which is exceptional in this case. The tumour was radically excised and the defect was reconstructed using arthrodesis, and a retrogradely perfused pedicle radialis fascial flap with skin graft, due to which amputation was avoided.
