Multiple chondromatous hamartomas of the lung

Abstract

Multiple chondromatous hamartomas (MCH) of the lung are very rare: only 16 cases have been reported to date. In young women, the tumours may be a manifestation of Carney triad (gastric leiomyoblastoma, pulmonary hamartoma and extra-adrenal paraganglioma) or Cowden syndrome (mucocutaneous lesions, multiple benign tumors of internal organs and increased risk for breast, thyroid, urogenital and digestive tract cancer). We report the 17th case of MCH of the lung, diagnosed accidentally in a 66 year-old male patient, with suspected concomitant hamartomas and malignant tumours.
