For me the first three first pictures look like digital mucous cyst, on the other pictures we see mature cartilage with foci of calcification that could be consistent with extraeskeletal chondroma

Has Geoff had a moment? Not sure how the digital, ganglionic type, mucus cyst relates to image 4 to 6.

Extraskeletal chondroma. Perhaps the intracorneal vesicle is a friction blister (not sure about keratinocytic degenerative changes in the underlying epidermis) or a secondary blister resulting from the increase in hardness of the soft tissue.

Digital mucous cyst. The patient had a 'loose body' associated with the communicating joint.
