[Puncture track metastasis after ultrasound-guided fine-needle puncture biopsy. A rare complication?]

Bilaterally enlarged adrenals were diagnosed by ultrasonography in a 57-year-old man with a potentially resectable adenocarcinoma of the lung. Ultrasound-guided fine-needle biopsy of the left adrenal revealed a metastasis, proven cytologically. Chemotherapy was tried but failed to influence tumour growth. Three months later a painful subcutaneous nodule was noted in the area of the previous needle puncture, which on removal proved to be a skin metastasis. The patient died later from the underlying tumour.
