Aim: To re-evaluate the use of CT-guided needle biopsy and VATS, as our combined approach protocol for the diagnosis and treatment of peripheral pulmonary nodules., Methods and Results: We describe the case of a male smoking patient, 50-year-old, who came to our service for the histological diagnosis of a right pulmonary lesion incidentally revealed. He was submitted to our diagnostic and therapeutic protocol for peripheral pulmonary nodules, that is a combined approach of CT-guided needle biopsy, anchorage of the lesion and VATS resection. Difficulties with this technique can raise when: 1. the cytological CT-guided needle biopsy is not diagnostic, 2. the anchorage is not successful, 3. the malignancy of the lesion cannot be surely determined by the extemporary histological examination. In this patient all these difficulties were encountered., Conclusions: We conclude that our diagnostic and therapeutic protocol for peripheral pulmonary nodules is not invalidated by this experience, even in consideration of the fact that we applied successfully the protocol in several previous cases.

Aim: To re-evaluate the use of 111In-pentetreotide scintigraphy (Octreoscan) in the follow-up of patients operated for carcinoids, as second-step investigation, after chest X-ray, CT-scan and serological marker' levels., Methods and Results: We describe the case of a female patient, 58-year-old, operated on for a non-secretory lung carcinoid. Five years after surgery, the CT-scan showed the enlargement of the bilateral hylo-mediastinal lymph nodes, suggestive for carcinoid recurrences. In order to confirm that, the patient was submitted to an Octreoscan that showed the presence of enlarged hylo-mediastinal adenopathies matching with the lesions observed at the CT-scan. Because the serological examination of NSE, chromogranin and serotonin, and the 5-HIIA were in the normal range, the patient was submitted to a lymph node biopsy through a mediastinoscopy. The histological examination of the specimens revealed a sarcoidosis and the patient was started on steroid therapy with good outcome., Conclusions: We conclude that: 1. the octreoscan scintigraphy in the follow-up of resected carcinoids can give false-positive results and 2. in consequence, the mediastinoscopy is a discriminating investigation in case of mediastinal lymph nodes disease.
