Recently, a novel group of CD34+ and S100+ spindle cell tumors with distinctive stromal and perivascular hyalinization showing recurrent gene fusions involving RAF1, BRAF, NTRK1/2/3, and RET has been identified. ALK rearrangements have been rarely reported in this group of tumors. We report a 24-year-old woman with a 1.

We report the first case of ipilimumab monotherapy resulting in durable complete remission of untreated, progressive brain metastases in a patient with stage IV melanoma. This case and earlier reports provide support for the further evaluation of ipilimumab in melanoma patients with brain metastasis.

Conclusion: Once the thoracic, abdominal, or pelvic wall is crossed by the introducer fitted with the sharp-tip stylet, the blunt-tip stylet replaces the sharp stylet for further progression in the fat toward the target. The soft-tip stylet carries a smaller risk of inadvertent perforation displacing vital structures.
