ÖZAmaç: Bu yazıda, sıra dışı yerleşimli osteokondromlu yedi olgunun klinik, radyolojik ve takip sonuçları bildirildi ve bu sıra dışı yerleşimli osteokondromların nadir ve sıra dışı özelliklerinin önemi vurgulandı. Şubat 2009 -Mart 2014 tarihleri arasında kliniğimizde (Antalya Memorial Hastanesi) tedavi edilen sıra dışı yerleşimli yedi osteokondromlu hasta bildirildi. Hastalar yerleşim yerlerine, bulgularına ve nörovasküler tutulum veya organ basısı varlığına göre sınıflandırıldı. Sonuçlar, mevcut literatür verileri eşliğinde tartışıldı. Hastalarımızın beşinde sıra dışı semptomatoloji vardı. Yedi hastanın altısına cerrahi eksizyon yapıldı. Bir hasta yalnızca planlı poliklinik viziti ile takip edildi. Klinik sonuçlarımız iyi ila mükemmeldi. Olgu serimizde, klavikula tutulumlu bir hastada omuz mekaniğinin bozulmasına bağlı omuz ağrısı; pubik tutulumlu bir diğerinde tıkalı idrar yolu bulguları ve dizüri vardı. Skapula tutulumlu bir hastada yalancı kanat skapula semptomları; fibula başı tutulumlu iki hastanın birinde peroneal sinir sıkışması ve diğerinde tibial sinir sıkışması semptomları vardı. İskiyal ramus tutulumlu bir hastada siyatalji; kaburga tutulumlu bir diğerinde ise herhangi bir semptom olmaksızın osteokondroma bağlı subklavyen arter basısının radyolojik bulguları vardı. Deneyimlerimize göre, fetal dönemde genellikle intramembranöz tipi kemikleşme yoluyla oluşan yassı kemikler (skapula, iliyum, pubik ramus, iskiyum ramus, kaburgalar ve klavikula dahil olmak üzere) nadiren çok daha az etkilenir ve sıklıkla sıra dışı semptomlar ile birlikte seyreder. Fibula başı kaynaklı osteokondromlar, ortopedi cerrahlarına masum görünebilir. Ancak, ortopedi cerrahları bu hasta grubunda tibiofibular sinositoz ve sinir basısına karşı uyanık olmalıdır.Anahtar sözcükler: Kemik doku; kıkırdak; eksizyon; neoplazma; osteokondrom. ABSTRACTHerein, we report clinical, radiological, and follow-up results of seven cases of extraordinary located osteochondromas and highlight the importance of rare and unusual properties of unusual locations of osteochondromas. Seven patients with extraordinary located osteochondromas were treated in our institution (Antalya Memorial Hospital) between the period of February 2009 and March 2014 were reported. The patients were classified according to the localization, symptomatology, and the presence of neurovascular involvement or organ compression. The results were discussed with the existing literature data. Five of our patients had unusual symptomatology. Surgical excision was performed on six of seven patients. One patient was followed with scheduled outpatient visits alone. Our clinical followup results were good to excellent. In our case series, one patient with clavicular involvement had impaired shoulder mechanic which resulted in painful shoulder, while another with pubic ramus involvement had obstructive urination symptoms and dysuria. One patient with scapular involvement had snapping scapula symptoms, while two patients with fibular head involvement had peroneal nerve compression and tibial...

Short-term cultures from 16 chondromatous tumors, 15 primary and one recurrent, were analyzed cytogenetically. Clonal chromosome aberrations were found in one of six benign tumors and in seven of ten malignant tumors. A chondroma had a complex translocation involving chromosomes X, 8, 12, and 13, as well as a deletion of the derivative chromosome 8. In the malignant tumors, monosomy 6 and 22 were observed in three tumors and monosomy 10, 11, 13, and 18 were observed in two tumors. In two of the three metastasizing tumors, del(5) (q13) and loss of chromosomes 6, 10, 11, 13, and 22 were common features. Structural aberrations of chromosome 1 were found in five tumors, of chromosomes 6, 12, and 15 in three tumors, and of chromosomes 4, 5, 9, and 20 in two tumors. We conclude that although considerable cytogenetic heterogeneity exists among chondromatous tumors, the karyotypic anomalies are still nonrandom.
