Calcinose tumorale chez un hémodialysé

Manel Jellouli, Tahar Gargah

Abstract


Tumoral calcinosis is a rare benign condition, characterized by calcium deposition in the soft tissue in extra-articular location which progresses toward a tumoral form. It can be primary or secondary to chronic renal insufficiency. We report a new case of tumoral calcinosis in a 27 years old young man. This patient with renal failure secondary to a malformative uropathy over a period of 15 years, was treated initially with peritoneal dialysis and hemodialysis. The patient presented since 5 months a gradual swelling of the hip causing difficulty walking. Examination revealed a stony consistency infiltration. There was no abnormal skin lesion. Pelvic radiograph highlighted significant diffuse calcium deposits in the Ssubcutaneous tissue. Bone scan showed increased uptake of the hip. MRI showed tumoral calcinosis of the posterior surface of the root of the thigh, measuring 14x13x12 cm, well limited, heterogeneous with fine peripheral and septal contrast, located at the level of large gluteal muscle, of the adductor magnus muscle and taking the proximal part of the conjoint tendon of the biceps femoris and the semitendinosus. This mass came into contact with the sciatic nerve without affecting the back. Laboratory tests found calcemy at 2,33 mmol/L, phosphoremy at 3,1 mmol/L, parathyroid hormone (PTH) at 770 ng/L and creatinine at 977 mol/L. The patient was offered a surgical procedure but he refused it.
