This patient was referred for an MRI following a GP review of a lesion on the back, features inconsistent with lipoma.

The MRI demonstrated no features of lipoma; therefore, the concern was raised of possible soft tissue tumor and referral was made to local sarcoma center. An ultrasound guided biopsy was then performed.

The core sample comprised spindle cells with some ganglion-like cells embedded in dense fibrous stroma, consistent with a low grade myofibroblastic lesion and represent ischemic fasciitis.
