hamartoma; benign malformation resembling a neoplasm
Medical term for a benign, tumor-like growth composed of tissue elements normally found at that site, but growing in a disorganized mass.
Lung hamartomas are often discovered without symptoms.
A hamartoma is not a true neoplasm, but a hamartomatous proliferation of tissue.
The term 過誤腫 is a medical compound of 過誤 (error, mistake) and 腫 (tumor, swelling), likely a calque from German 'Hamartom' or English 'hamartoma', which itself derives from Greek 'hamartia' (error). The exact derivation is uncertain.
