  • summary
    • Squamous Cell Carcinoma is a malignant soft tissue tumor most commonly found in elderly patients.
    • Diagnosis is made with a biopsy.
    • Treatment is wide surgical resection with or without radiation and skin grafting.
  • Epidemiology
    • Anatomic location
      • dorsum of hand and forearm
      • most common subungual malignancy
    • Risk factors
      • primary risk factor is excessive exposure to ultraviolet radiation
      • actinokeratosis
      • Solid organ transplant
      • chronic osteomyelitis
        • Marjolin's ulcer is a squamous cell carcinoma resulting from chronic draining wounds or burn scars

    • Operative
      • wide surgical resection +/-skin graft +/- radiation
        • indications
          • standard traditional treatment
        • adjunctive radiation
          • indications
            • lesions >2cm wide
            • 4mm deep
            • perineural invasion
            • lymph node metastases
      • Mohs microsurgery
        • indications
          • becoming more popular
          • smaller lesions
          • highest cure rate
        • technique
          • lymph node biopsy may be necessary
  • Prognosis
    • Metastasis
      • lymph node metastases and high histologic grade confer poor prognosis
      • higher metastatic potential than basal cell carcinoma

QID 219803 (Type "219803" in App Search)
A 52-year-old recreational surfer presents with shoulder pain and weakness after being hit forcefully by a wave while trying to recover his board with his arm in hyperabduction and external rotation. On examination, he has a positive bear hug test, active internal rotation to neutral on the affected side, and passive external rotation of 100 degrees compared to 70 degrees on the unaffected side. He comes to the clinic with an MRI, a representative image of which is shown in Figure A. You are planning to book him for a rotator cuff repair with a suprapectoral arthroscopic biceps tenodesis. Injury to which of the following structures most likely contributed to the findings shown in Figure A?
