Pulmonary hamartoma is a rare lung neoformation, usually symptomless and by
chance discovered, of a probable dysontogenetic origin with prevailing car
tilaginous tissue and adult, onset age. The Authors report a rare case of a
25-year-old student, symptomless and fortuitosly found by means of a radio
graph of the chest, Many interesting features characterize the case report:
histological nature of the pulmonary hamartoma, mainly vascular, so much a
s to feign an angiosarcoma at the macroscopical examination, and with small
peripheral calcifications as shown by lung CT scan; the measures( about 7
cm)plentifully above the parameters usually reported in the literature (fro
m 2 cm to 4 cm); the young onset age (about 10 years old), We may consider
a case exceptionally reported in the literature. Besides, on the base of a
few studies and of our experience, the results of the pulmonary hamartoma g
rowth rate and doubling time are reported.
