The Hypertrophic Osteoarthropathy is a syndrome caracterized by three main features: clubbing of fingers and ankee bones, poliarthritis and periosteal reaction. Several precursory diseases, throracic or nonthoracic may develop this syndrom and pul monary carcinoma plays an outstanding role in this group. Its ethiology is unknown and a great deal of theorys try to explain the mechanism of its formations. The production of a toxic substance by the primary disease might be responsible for the ativation of the periostic reaction. The periostic reaction mainly attacks long bone diaphysis (femoris, humeri, etc) in a simetric pattern which can be confirmed by X-ray and bone scintigraphy. According to the literature secondary Hypertrophic Ostteoarthropathy plays the role of an effect preeceding the cause and may present a manifestation even two years before the disease which caused it we report the casew of a 62-year-old male, seen by an orthopedist because of important pains and aches in the lower members, mainly the thighs and a bone scintigraphy was requestd showing as result an increased uptake of the radiopharmaceuticals in the cortical edge of femoris, being interpreted as HO. Several siple X-rays of lower members were carried out after the scintigraphy confirming the periostitis. Its ethiology was investigated, but with no success. After a two-year-accompaniment, the patient has reported specific pulmonary complaints, which led to a pulmonary biopsy diagnosed as Pulmonary Adenocarcinoma. The coinclusion were that the scintigraphy is indeed an important method to diagnose the disease (HO) and the findings related to it may preced the radiographic alterations.
