Multiple unexpected lesions of metachondromatosis detected by technetium-99m methylene diphosphonate SPECT/CT: A case report.

Medicine (Baltimore) 2018 Apr;97(17):e0512

Department of Nuclear Medicine, The Affiliated Hospital of Southwest Medical University.

Rationale: Metachondromatosis (MC) is a very rare genetic disease, which is infrequently reported worldwide, which leads to osteochondroma and enchondromatosis. The disease has been shown to be associated with loss of function of the tumor suppressor gene "protein tyrosine phosphatase, non-receptor type 11" (PTPN11).

Patient Concerns: A 12-year-old female was admitted to the hospital with pain due to an enlarged mass in her left fifth finger. Read More

The association of enchondromatosis with malignant transformed chondrosarcoma and ovarian juvenile granulosa cell tumor (Ollier disease).

Taiwan J Obstet Gynecol 2017 Apr;56(2):253-257

Gynecologic Oncology Center, Department of Obstetrics and Gynecology, First Faculty of Medicine, Charles University and General University Hospital in Prague, Czech Republic. Electronic address:

Objective: Ovarian juvenile granulosa cell tumor has an interesting association with multiple enchondromatosis (Ollier disease and Maffucci syndrome) and should be considered a leading diagnosis when an ovarian mass is found in young patients with these conditions. Besides the association with nonskeletal malignancies, there is a high risk of malignant transformation of enchondroma in chondrosarcoma as was also the case in this instance.

Case Report: The report uses multiple images to document the representative and characteristic markers of multiple enchondromas in a 22-year-old patient with Ollier disease complicated by malignant transformation of chondrosarcoma and in whom the disease is associated with ovarian juvenile granulosa cell tumor of the right ovary.

Maffucci Syndrome. An Interesting Case and a Review of the Literature.

Bull Hosp Jt Dis (2013) 2015 Dec;73(4):282-5

Maffucci syndrome, a rare sporadic form of enchondromatosis, is characterized by hemangiomas and multiple enchondromas, benign cartilaginous tumors that arise near growth plates. Previous studies demonstrate that individuals diagnosed with Maffucci syndrome have approximately 100% lifetime risk of malignant transformation. Identification of Maffucci syndrome by surgical excision and pathological diagnosis can be life-saving due to its high malignant potential relative to other subtypes of enchondromatosis such as Ollier's disease.

Spinal and extraspinal deformities in a patient with dysspondyloenchondromatosis.

Ger Med Sci 2013 28;11:Doc06. Epub 2013 Mar 28.

Pediatric Orthopedic Institute n.a. H. Turner, Department of Foot and Ankle Surgery, Neuroorthopaedics and Systemic Disorders, Saint-Petersburg, Russia.

Anisospondyly (irregularly shaped vertebral bodies) and enchondroma-like lesions in the metaphyseal and diaphyseal portions of the long tubular bones are the characteristic features in patients with dysspondyloenchondromatosis (DSC). Thoraco-lumbar scoliosis and windswept deformity of the lower limbs were the major abnormalities encountered in this patient. To the best of our knowledge this is the first case report delineating the spine pathology via reformatted CT scan and the correction of a windswept deformity by means of temporary hemiepiphysiodesis in a patient with (DSC).

IDH1 and IDH2 mutations are frequent events in central chondrosarcoma and central and periosteal chondromas but not in other mesenchymal tumours.

J Pathol 2011 Jul 19;224(3):334-43. Epub 2011 May 19.

Department of Histopathology, Royal National Orthopaedic Hospital NHS Trust, Stanmore, Middlesex HA7 4LP, UK.

Somatic mutations in isocitrate dehydrogenase 1 (IDH1) and IDH2 occur in gliomas and acute myeloid leukaemia (AML). Since patients with multiple enchondromas have occasionally been reported to have these conditions, we hypothesized that the same mutations would occur in cartilaginous neoplasms. Approximately 1200 mesenchymal tumours, including 220 cartilaginous tumours, 222 osteosarcomas and another ∼750 bone and soft tissue tumours, were screened for IDH1 R132 mutations, using Sequenom(®) mass spectrometry.

Treatment outcome of enchondroma by simple curettage without augmentation.

J Orthop Sci 2010 Jan 12;15(1):112-7. Epub 2010 Feb 12.

Department of Orthopedic Surgery, Kyorin University, Tokyo, Japan.

Background: Simple curettage for enchondroma without augmentation, known to lead to spontaneous bone consolidation at the curettage site, is a potential standard treatment for this condition. However, few detailed data comparing the results of this technique with conventional methods including reconstruction are available, and the relation between the postoperative completion period for bone consolidation and preoperative independent variables is not known.

Methods: The subjects included 38 patients with enchondroma treated with simple curettage without augmentation. Read More

Maffucci's syndrome is an uncommon congenital disease marked by multiple vascular malformations and enchondromas throughout the body. Otolaryngologic manifestations are relatively rare but potentially can cause symptoms such as respiratory distress and dysphagia if the lesions appear in the upper aerodigestive tract or larynx. We report a case of a young woman who demonstrated a wide range of head and neck pathology associated with this unique disease, including sphenoid enchondroma, bilateral petrous apex lesions, and rarely reported laryngeal and hypopharyngeal vascular malformations, over a period of nearly 20 years.

Radiographs and CT scans showed a periosteal lesion producing saucerization without periosteal reaction and calcification in the distal metaphysis of the right fibula. MRI showed an intramedullary lesion adjacent to the periosteal lesion, although it was invisible at CT. Read More

[Long-term results of autograft and allograft applications in hand enchondromas].

Acta Orthop Traumatol Turc 2004 ;38(5):337-42

Department of Orthopedics and Traumatology (Ortopedi ve Travmatoloji Anabilim Dali), Medicine Faculty of Celal Bayar University, Manisa, Turkey.

Objectives: We evaluated the long-term results of treatment with curettage followed by an autograft or allograft application in patients with enchondroma of the hand.

Methods: Within a 15-year period, 76 patients (41 males, 35 females; mean age 32 years; range 14 to 47 years) were operated on for enchondroma of the hand. Following curettage of the lesion, reconstruction of the defect was made either by an autograft obtained from the iliac crest (n=76) or by a dehydrated cancellous allograft (n=15). Read More

[Multiple enchondromatosis: Ollier's disease].

Unfallchirurg 2002 Dec;105(12):1139-42

Abteilung für Unfallchirurgie,Hand- und Wiederherstellungschirurgie, Universität Ulm.

In contrast to solitary enchondroma,patients with multiple enchondromatosis of bone (Ollier's disease) get affected in childhood by bone swelling and growth retardation. In adults, the main problem is the risk of malign transformation up to 40%.Pain, increasing local tumor and thinning of the corticalis are the typical clinical and radiological signs of transformation to a low grade chondrosarcoma.

Natural history of chondroid skull base lesions--case report and review.

Neuroradiology 2002 Mar;44(3):268-71

Department of Neurosurgery, Nordstadt Hospital, Hannover, Germany.

Long-term follow-up reports on chondroid lesions of the skull base are rarely presented in the literature. There are virtually no data on natural growth rates of these tumors based on MRI obtained over a period of 10 years or longer. We followed a patient who has had such a lesion for more than 12 years.

Enchondroma and chondrosarcoma.

Semin Musculoskelet Radiol 2000 ;4(1):59-71

Department of Radiology, National Naval Medical Center, Bethesda, Maryland 20889-5600, USA.

Enchondroma and chondrosarcoma are two of the most commonly encountered primary bone lesions in the typical radiology practice. The purpose of this article is to review the clinical, radiological, and pathological features that distinguish conventional chondrosarcoma from enchondroma. Chondrosarcoma is almost always associated with pain and tends to present in the axial skeleton of middle aged adults. Read More

Benign chondroid neoplasms of bone.

Semin Musculoskelet Radiol 2000 ;4(1):45-58

Department of Radiology, University Hospitals of Cleveland, Case Western University School of Medicine, Ohio, USA.

Benign cartilage lesions discussed in this article include osteochondroma (solitary, epiphyseal, and multiple), chondroblastoma, periosteal chondroma, and chondromyxoid fibroma. These lesions often demonstrate imaging appearances strongly suggesting the above diagnosis, particularly the "ring and arc" mineralization characteristic of cartilage lesions, which reflects their underlying pathology. This article emphasizes the imaging spectrum of these lesions with a multimodality approach. Read More

Benign and malignant cartilage tumors of bone and joint: their anatomic and theoretical basis with an emphasis on radiology, pathology and clinical biology. I. The intramedullary cartilage tumors.

Skeletal Radiol 1997 Jun;26(6):325-53

Orthopaedic Oncology Service, Orthopaedic Hospital, Los Angeles, CA 90007, USA.

We reviewed 845 cases of benign and 356 cases of malignant cartilaginous tumors from a total of 3067 primary bone tumors in our database. Benign cartilaginous lesions are unique because the epiphyseal plate has been implicated in the etiology of osteochondroma, enchondroma (single or multiple), periosteal chondromas and chondroblastoma. In the first part of this paper, we will review important clinical, radiologic and histologic features of intramedullary cartilaginous lesions in an attempt to support theories related to anatomic considerations and pathogenesis.
