“…In addition to a thick cartilage cap with prominent calcifications, soft tissue invasion, infiltration of the stalk, erosion of bone, and tumor invasion of the underlying bone are features of malignant transformation (Table 1). 1,2,9,11,16,17 Osteochondromas are usually observed or resected in symptomatic patients. Symptoms may be due to mechanical issues, impingement on adjacent nerves, development of a bursa on the surface of the cap, or a pathologic fracture through the stalk.…”

Context.— Cartilaginous tumors represent one of the most common tumors of bone. Management of these tumors includes observation, curettage, and surgical excision or resection, depending on their locations and whether they are benign or malignant. They can be diagnostically challenging, particularly in small biopsies. In rare cases, benign tumors may undergo malignant transformation. Objective.— To review common cartilaginous tumors, including in patients with multiple hereditary exostosis, Ollier disease, and Maffucci syndrome, and to discuss problems in the interpretation of well-differentiated cartilaginous neoplasms of bone. Additionally, the concept of atypical cartilaginous tumor/chondrosarcoma grade 1 will be discussed and its use clarified. Data Sources.— PubMed (US National Library of Medicine, Bethesda, Maryland) literature review, case review of archival cases at the Massachusetts General Hospital, and personal experience of the authors. Conclusions.— This review has examined primary well-differentiated cartilaginous lesions of bone, including their differential diagnosis and approach to management. Because of the frequent overlap in histologic features, particularly between low-grade chondrosarcoma and enchondroma, evaluation of well-differentiated cartilaginous lesions should be undertaken in conjunction with thorough review of the imaging studies.

“…[8] Flat bones like the scapula and hip may also be involved .Despite the slight predominance of the male gender over the female gender that has been reported by some authors, it seems that there is no effective predilection according to sex. [11] Osteochondroma is usually symptomless and, therefore, the only clinical symptom is a painless slowgrowing mass on the involved bone.…”

“…Other clinical findings that are occasionally reported include slight increases in soft tissues, elevation of temperature and local erythema. [11] Osteochondromas are slow growing lesions with rare malignant transformation but can raise cosmetic concerns and impinge on local structures, including nerves, vessels and tendons, leading to symptomatology. [8,18,19] The majority of lesions are solitary, but they can occur as multiple lesions as part of the syndrome hereditary multiple exostosis (HME), which affects approximately 15% of patients with osteochondromas and is an autosomal dominant inherited disorder.…”

Background: Osteochondroma is the most common tumor of bone, accounting for approximately one third of benign lesions in the skeleton, is a broad (sessile) or narrow (pedunculated) skeletal protrusion comprised of marrow and cortical bone. Although it is benign, its biological behavior still has a malignant potential. Chondrosarcoma arising in osteochondroma has been recognized for many years. Osteochondromas might occur on any bone preformed in cartilage, they were especially seen on the long bones of the extremities, predominantly around the knee. In fact, the lower limb seemed to be at a higher risk of the tumor than the upper limb on the top two locations: distal part of the femur and proximal part of the tibia, however, the proximal humerus ranked the third place for solitary osteochondroma while the proximal fibula for multiples osteochondromas. Methods and Findings:A total of 20 skeletons and 18 cadavers of both sex, 16 males and 2 females, with different age groups were used, this study was carried out by routine dissection classes for undergraduate medical student´s in the Morphology Laboratory of the University of Pamplona during the years 2013-2016. In only one sample was found the presence of osteochondroma. The measurement of the osseous mass was of 7x3.5x1.5 cm, attached to the posterolateral aspect of the middle third of the femur. Conclusions:Osteochondroma is generally asymptomatic or discovered accidentally, but it can cause different symptoms depending on site of occurrence local swelling, bony deformities, fracture, bursa formation, arthritis and impingement on adjacent tendons, vascular or neurologic compromise, and dislocation The importance of correct treatment and follow-up of large osteochondromas to avoid complications such as further damage to neighboring neurovascular structures, and potential malignant degeneration. The present study describe a rare location from an osteochondroma in the femur diaphysis.

“…It is composed of corticomedullary bone with hyaline cartilage. Most commonly located in long bones, in the appendicular skeleton; of predominance in the knee, femur and humerus, less frequently in flat bones such as the scapula and the hip [22]. Its presence is associated to cartilaginous exostosis that may produce aesthetic and bone deformity as well as articular disfunction.…”

Elastofibroma Dorsi: Review of Literature with Radiological Approach

Elastofibroma Dorsi is a benign soft tissue tumor, that is rare; commonly located in the scapula, and found more frequently presented in women. Its etiology is unknown, but is mostly associated to the result of mechanical friction between two musculoskeletal surfaces. It is frequently manifestated as an asymptomatic mass, with variable size and location. Its diagnosis is clinical, however there are numerous diagnostic aids, of which the most relevant is magnetic resonance for its ability to characterize the lesion. The differential diagnoses are lipoma, liposarcoma, sarcoma, hemangioma, desmoid tumor and osteosarcoma. Its definite treatment is surgical resection.
