Conclusion

The lesions of the first patient proved to be a malignant myxofibrosarcoma and the lesion of the second patient proved to be a benign nodular fasciitis.
Both lesions have unsharp borders and so we could not exclude malignancy. If you look at the location of the nodular fasciitis perhaps that could have helped you in the differential diagnosis.
But both patients were referred for biopsy and further treatment.
