We report a case of triple elastofibromas located in the supra- and infrascapular regions. A 61-year-old female with a history of bilateral elastofibroma in the typical subscapular region (6 years before) was admitted for the evaluation of a left-sided suprascapular mass that she had first noted 3 months before. On physical examination, a firm, painless, mobile mass was palpated in the subcutaneous tissue. The patient had not observed any changes of the two known lesions over the past 6 years. The patient denied a family history of elastofibroma. The signal characteristic on T1- and T2-weighted images as well as contrast enhancement curves on dynamic study was identical in all three masses. Ultrasound-guided biopsy performed before surgical intervention confirmed the diagnosis of elastofibroma. This case report has a teaching value as, to our knowledge, it is the only one in the literature with images of synchronous elastofibromas documented by dynamic contrast-enhanced MRI. In cases of elastofibroma with diagnostic difficulties, particularly in uncommon sites, a dynamic contrast-enhanced MRI may help to establish the proper diagnosis. This case report gives an example of rare multiple elastofibromas, presents current diagnostic imaging methods, and reminds us that elastofibroma is not exclusive to the posterior thoracic region.

Purpose: To evaluate the medium-term outcome of mosaicplasty for full-thickness cartilage defects of the knee joint in 17 patients., Methods: Records of 12 men and 5 women aged 16 to 57 (mean, 35) years who underwent mosaicplasty for grade III/IV osteochondral defects in the lateral (n=14) or medial (n=3) femoral condyle were reviewed. 12 of the patients had undergone knee surgeries. The mean size of the defects was 3.4 (range, 1-4) cm(2). Three patients had defects of >2 cm(2). All operations were performed by a single surgeon using mini-arthrotomy. The lateral edge of the trochlea was the donor site. Graft integration and the presence of any abnormality at the articular surface were assessed using magnetic resonance imaging (MRI). In addition, patients were evaluated using the International Knee Documentation Committee (IKDC) rating scale, the SF-36 health questionnaire, visual analogue scale (VAS) score for pain., Results: Two of the 17 patients developed necrosis and cystic degeneration of the grafts and underwent conversion to unicompartmental knee arthroplasty within 2 years. They were older than 45 years and had defects of >2 cm(2). Respectively in years 4 and 7, one and 4 patients were lost to follow-up, the mean IKDC score was 75% and 88%, the SF-36 score was 83% and 90%, and the VAS score was ≤3 in 13 of 14 patients at year 4 and in all 11 patients at year 7. At the 7-year follow-up, patient satisfaction with mosaicplasty was excellent in 8 patients, good in 3, and poor in 2 (who underwent unicompartmental knee arthroplasty). At year 4, MRI showed integration of the cartilage repair tissue and incorporation of the osseous portion of the graft into the bone in 13 of the 14 patients. The remaining patient had osteoarthritis at the graft donor site. At year 7, MRI showed good integration of the implant in all 11 available patients, but fissures were seen on the cartilage surface in 3 patients., Conclusion: The medium-term outcome of autologous mosaicplasty for symptomatic osteochondral defects in the femoral condyle is good. Longer follow-up is needed to determine the structural and functional integrity of the graft over time.
