Abstract

BACKGROUND: Infantile cartilaginous hamartoma of the rib is a rare condition occurring in newborn infants, with an incidence of 1 in 3,000 (0.03%) among primary bone tumor cases. Reports of this condition so far have presented the clinical, radiologic and histopathologic features. To the best of our knowledge, reports of the cytopathologic features have not been documented. In the present case report, clinical, radiologic and cytopathologic features and differential diagnosis are enumerated. CASE: A 1-month-old, male infant presented with a chest wall mass with a clinical diagnosis of osteochondroma. On fine needle aspiration cytology, a diagnosis of infantile cartilaginous hamartoma of the rib was suggested; it was supplemented by the clinical history and radiologic findings. CONCLUSION: Although rare, this condition ought to be kept in mind while dealing with infantile chest wall masses to avoid an erroneous diagnosis of malignancy, owing to its ominous cytopathologic features.
