If you move the transducer you can see a nerve coming from the lesion, which also proved to be a schwannoma. It's the most common type of benign peripheral nerve tumor in adults. It can occur anywhere in the body, at any age. When it arises from a larger

Conclusion

The first lesion proved to be an ancient schwannoma of the superficial peroneal nerve. The second lesion was also a schwannoma.
