[Chondromatose of the temporomandibular joint: Multicentric study and clarification from 14 cases]. / Chondromatose de l'articulation temporomandibulaire : étude multicentrique et mise au point à partir de 14 cas.

INTRODUCTION: The aim of our study was to analyse a series of patients suffering from temporomandibular joint (TMJ) chondromatosis treated in 2 departments of stomatology and maxillofacial surgery (University hospitals of the Conception in Marseille and of Caen) and to make a general review of this disease. MATERIAL AND METHODS: We conducted a retrospective study including all the patients treated for a TMJ chondromatosis in one of these 2 departments. Following parameters were analyzed: sex, ages at discovery and at surgery, symptoms, side, imaging, histology, recurrence and any other events considered as relevant. RESULTS: Fourteen patients could be included: 85.7 % were women. Average age at diagnosis was 40.14 (σ = 13.82; IC95: 32.90-47.38) (41 for women [σ = 14.74; IC95: 33.28-48.72] and 35 years for men [σ = 5.66, IC95: 27.16-42.84]). Average age at surgery was 40.86 (σ = 14.18; IC95: 33.43-48.28). There was no predominance of side; 57.14 % of the patients had a joint syndrome, 57.14 % a tumor syndrome, 28.57 % had pain and 14.29 % had headaches. Panoramic X-ray was informative in 3 cases only. CT scan showed intra-articular calcifications in half of the cases only but arthrosic modifications in all the cases. Magnetic resonance imaging (MRI) constantly showed intra-articular cartilage fragments. When histology was performed, it found the synovial to be normal in one case and multiple nodules with clear cartilaginous differentiation in another case. One patient suffered from a second contralateral localization 10 years later. DISCUSSION: Chondromatosis has a slow evolution and is asymptomatic for a long time. MRI allows to evoke the diagnosis and to locate precisely the osteochondromas. Diagnosis is confirmed by histology that highlights a synovial metaplasia and more or less calcified chondromas. The main differential diagnosis to be eliminated because of prognostic reasons is the synovial chondrosarcoma. Treatment consists in surgical removing of the chondromas. Evolution is usually favorable.

Condromalacia de rótula: incidencia de algunos aspectos clínicos, terapéuticos y epidemiológicos / Patellar chondromalacia: behavior of some clinical, therapeutical and epidemiological aspects

Se realizó un estudio explicativo en un número de trece pacientes diagnosticados y tratados por condromalacia de rótula mediante artroscopia en el Hospital Provincial Docente "Manuel Ascunce Domenech" de nuestra ciudad. Se encontró una mayor incidencia en el sexo femenino con un 61,5 por ciento. El grupo de edades con mayor afección fue el de más de 45 años para un 38,4 por ciento. Predominó la condromalacia grado II en el 46,! por ciento. Las lesiones de menisco fueron las afecciones asociadas más frecuentes en un 38,4 por ciento. El índice de complicaciones en este proceder es muy bajo con solo un 15,3 por ciento(AU)

Gastric leiomyoblastoma associated with extraadrenal paraganglioma and pulmonary chondroma: a new case of Carney's triad.

Carney's triad is extremely rare. The authors report on a 12-year-old patient who had gastric epithelioid leiomyosarcoma, multiple pulmonary chondroma, and mediastinal paraganglioma. Thirty-five other cases are reviewed and analyzed.
