Surgical Management of Onychopapilloma, Onychomatricoma, and Subungual Osteochondroma: Case Series.

J Cutan Aesthet Surg 2018 Jul-Sep;11(3):143-147

Department of Dermatology, Topiwala National Medical College and B. Y. L. Nair Charitable Hospital, Mumbai, Maharashtra, India.

The clinical diagnosis of benign and malignant nail tumors can be difficult. Dermoscopy can provide a clue to the diagnosis but nail biopsy is the gold standard in establishing the diagnosis. Here, we report three cases of rare nail tumors, that is, onychopapilloma, onychomatricoma, and subungual osteochondroma, which were diagnosed on histopathology and managed surgically. Read More

Regression of a solitary osteochondroma of the distal humerus in a toddler following trauma.

Radiol Case Rep 2019 Feb 7;14(2):187-189. Epub 2018 Nov 7.

Gold Coast University Hospital Radiology Department, 1 Hospital Blvd, Southport QLD 4215, Australia.

Osteochondromas are bone exostoses, with the vast majority extending from the metaphyseal region of long bones and are capped by cartilage. A review of the current literature reveals spontaneous regression of osteochondromas is a rarely documented event, with all but two of these recorded events resolving before skeletal maturity and within 6 years of identification. We present a case of trauma-induced resolution of a solitary osteochondroma after less than 3 months in a 15-month-old male, with a review of current literature. Read More

JB JS Open Access 2018 Jun 29;3(2):e0064. Epub 2018 May 29.

Department of Pathology, Institute of Biomedical and Health Sciences, Graduate School of Hiroshima University, Hiroshima, Hiroshima, Japan.

Background: Reported information on the characteristics of benign bone tumors is disjointed, and the long-term trends in the occurrence of malignant bone tumors by histological type have not been reported in Japan. Our aim was to describe the characteristics of both benign and malignant bone tumors as described in cases registered in the Hiroshima Tumor Tissue Registry from 1973 to 2012.

Methods: Cases were identified with the International Classification of Diseases for Oncology (ICD-O-3) topography code C40-C41 (bones, joints, and articular cartilage), and histological types were classified according to the World Health Organization 2013 system. Read More

Radiologia 2018 Sep 28. Epub 2018 Sep 28.

Servicio de Diagnóstico por Imágenes, Hospital Italiano de Buenos Aires, Ciudad Autónoma de Buenos Aires, Argentina.

Sternal tumours are rare in children. The differential diagnoses include a wide spectrum of benign (from bone cyst to osteoblastoma, osteochondroma and fibrous displasia) and malignant tumours (Ewing's sarcoma, chondrosarcoma rhabdomyosarcoma), inflammatory lesions and infectious processes. The SELSTOC (Self Limiting Sternal Tumours of Childhood) are entities of non-specific origin, they are self-limiting and characterised by a rapidly growing tumour that disappears spontaneously with no history of trauma or active infection.

miR-503 is down-regulated in osteosarcoma and suppressed MG63 proliferation and invasion by targeting VEGFA/Rictor.

Cancer Biomark 2018 Aug 28. Epub 2018 Aug 28.

Department of Orthopaedic Surgery, Shengjing Hospital of China Medical University, Shenyang 110000, Liaoning, China.

We analyzed the expression of miR-503 in osteosarcoma tissues (OS) and discussed the clinical significance of our findings. To provide a theoretical basis for clinical applications, prognosis prediction and treatment of osteosarcoma, we studied the biological function of miR-503 and its mechanism in MG63 osteosarcoma cells. Real-time polymerase chain reaction (PCR) was used to detect the expression of miR-503 in 45 OS tissues and 20 osteochondroma tumors, analyzing the relationship between clinical pathology and follow-up data.
