Digital papillary adenocarcinoma (abbreviated DPA), also aggressive digital papillary adenocarcinoma (abbreviated ADPA), is a rare malignant skin tumour.[1]
General
- Very rare.
- Aggressive - amputation is typically recommended.[2]
- Typically males 50-80 years old.
- May be seen in adolescents.[3]
Gross
- Distal end of a finger or toe.
- Usually fingers.[1]
Microscopic
Features:
- Papillary projections - very common, not required.
- Tubular structures.
- Basaloid cells usually with mild-to-moderate atypia.
- Fibrous stroma.[4]
DDx:
- Basal cell carcinoma.
- Other basaloid tumours.
