ABSTRACT
Metastases from melanoma have a very poor prognosis for the patient. Single metastatic lesions in the sternum due to melanoma are extremely rare. A rare case of a presternal mass in a 56-year-old patient who had undergone excision for malignant melanoma is presented. Review of the patient's history and surgical resection of a single metastatic soft tissue lesion offer the best chance of long-term survival.
ABSTRACT
BACKGROUND: EBUS guided trans-bronchial biopsy became routine in diagnosis of peripheral pulmonary lesions (PPL). Suction catheter-biopsy is a technique for obtaining a tissue sample from peripheral lung parenchyma. Aim of this study was to evaluate diagnostic efficiency, feasibility and safety of EBUS guided suction catheter-biopsy (SCB) in comparison to trans-bronchial biopsy (TBB) in diagnosis of PPL. The main intention was to demonstrate non-inferiority of the technique over trans-bronchial biopsy, especially when used under navigation of the EBUS. METHODS: Radial EBUS probe (UM-3R, Olympus Co, Japan.) without guiding sheath was used to navigate suction catheter and TBB forceps to the PPL. The catheter was connected to the collection canister via vacuum pump. The SCB specimens were fixed with 10% buffered formalin. RESULTS: There were 168 patients enrolled in this study; 69.9% males and 30.1% females. Main lesion diameter was 4.1±1.9 cm. Majority of patients, 131(77.9%) were diagnosed with lung cancer. Per-biopsy calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for EBUS-SCB were 92.4%, 100%, 100% and 67.7%, respectively. Corresponding values for EBUS-TBB were 92.3%, 100%, 100% and 69.7%. Only the size of the lesion significantly influenced (p=0.005) diagnostic performance. Complications occurred in 2 patients; one pneumothorax and one excessive bleeding. CONCLUSION: EBUS guided SCB is efficient, feasible and safe in diagnosis of peripheral lung cancer. The technique is complementary to trans-bronchial biopsy.
ABSTRACT
Synchronous multiple primary lung cancer (SMPLC) is rare and very hard to distinguish from metastatic disease. Recent studies indicate the presence of this entity in the lung, with no mention to the involvement of the mediastinum. An extremely rare case of a 68-year-old male with double primary non-small cell lung cancer (NSCLC) in the left upper lobe and N2 positive nodes for small cell lung cancer (SCLC) is presented. Modern diagnostic criteria as well as aggressive curative strategies are encouraged, in order to achieve better survival rates for such patients.
