Digital papillary adenocarcinoma
Diagnosis in short

Synonyms aggressive digital papillary adenocarcinoma
LM DDx basal cell carcinoma, other basaloid tumours
IHC pankeratin +ve, CEA +ve (edge of ducts/spaces), EMA +ve (edge of ducts/spaces), S-100 +ve (luminal cells), SMA +ve (outer myoepithelial cell layer), p63 +ve (outer myoepithelial cell layer)
Site skin - digits (fingers or toes)

Prevalence very rare
Prognosis aggressive
Treatment ampuation

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]
