54 year old female with a history of minor injury to the finger 6 months before these studies were obtained, subsequently developed an infection requiring debridement. The wound was then stable until 2 months before, when a large, fungating, hemorrhagic mass grew.
X-ray shows large radiopaque mass eroding the distal finger (distal phalanx and distal portion of the middle phalanx).
CT 3D surface reconstructions show the morphology of the mass.
CTA 3D reconstruction shows the mass is very hypervascular.
Lymph node scintigraphy was performed showing a sentinel node at the axilla (not shown). The patient underwent amputation of the finger with axillary sentinel node biopsy, which was positive for metastatic melanoma. The patient was then lost to follow-up.
Well that's terrifying. You're just minding your own business and all of a sudden your finger is a toasted marshmallow.
