Un carcinome thymique révélé par une ostéoarthropathie hypertrophiante.

Hypertrophic osteoarthropathy (OAH) is a primary or secondary clini coradiological entity. OAH is most often secondary to pulmonary neoplasia. We report a rare case of OAH secondary to thymic carcinoma. A 60-year-old Men with no pathological history, he was a nonsmoker. He has been suffering from distal polyarthritis for 2 months, in a context of asthenia and weight loss. The clinical examination revealed a digital clubbing, synovitis of the knees and ankles bilateral and symmetrical. His balance sheet showed periosteal appositions of the long bones of the upper and lower limbs, without pinching or erosion, and an inflammatory syndrome. The chest CT SCAN shows a heterogeneous tissue mass of the thymic compartment, the biopsy has concluded that there is undifferentiated thymic carcinoma. The occurrence of OAH during thymic carcinoma may be a sign of poor prognosis, given the possible relationship between VEGF and OAH. [ABSTRACT FROM AUTHOR]
