An Aggressive Digital Papillary Adenocarcinoma and a Grossly Similar, Contralateral Callus: A Case Report.

CASE: This is a case of a 44-year-old man with 10 years of history of painful callus-like swellings of bilateral index fingers. Sudden enlargement of the left index finger prompted biopsy, which revealed aggressive digital papillary adenocarcinoma (ADPA) that was treated with partial amputation. Biopsy of the contralateral finger revealed acanthotic skin with no evidence of malignancy. CONCLUSION: Several case reports cite antecedent insult and chronic swelling before diagnosis. We describe a case of bilateral lesions with similar gross appearances, a long history of occupational repetitive trauma, and sudden enlargement of 1 lesion leading to the diagnosis of ADPA.

Intramedullary Suture Anchor Fixation of a Type Vb Flexor Digitorum Profundus Avulsion: A Case Report.

CASE: Flexor digitorum profundus avulsions are common injuries that manifest as tendinous or bony avulsions from the distal phalanx. Rarely, additional fractures can occur in the distal phalanx. For such injuries, repair of the avulsion and fracture is recommended but difficult because of limited bone stock for fixation. CONCLUSION: We present a case of a 28-year-old man with a combined flexor digitorum profundus bony avulsion and bony mallet finger, and describe a strategic fixation technique using an intramedullary suture anchor and dorsal button that provided stable fixation and resulted in excellent motion and function, with return to sport at 12 weeks.
