Definition / general
  • #2 most common primary malignancy of trachea after squamous cell carcinoma
  • Resembles salivary gland tumor
Clinical features
  • Usually in upper third of trachea
  • Intramural (15%) or extramural (85%)
  • Symptoms: dry cough, dyspnea, hemoptysis
  • May coexist with main bronchus lesion
  • 20% invade locally (including thyroid gland); may metastasize to lymph nodes, nasal cavity, liver
  • Lengthy clinical course but poor long term prognosis due to late local recurrences
  • Median overall survival 18 years, median disease free survival 10 years
  • 75% survival rate if complete resection
  • Predictors of survival: margin status, extramural disease, perineural invasion, lymph node metastases (Eur J Cardiothorac Surg 2010;37:1438, Ai Zheng 2004;23:581

Treatment
Microscopic (histologic) description
  • Cribriform growth pattern of nests of tumor cells with discrete, rounded, "punched out" gland-like spaces filled with eosinophilic or basophilic material
  • Infiltrative, perineural invasion common
