Extraskeletal Osteochondroma of the ButtockOsteochondromas are common and typically arise from the metaphyseal ends of long bones. An osteochondral neoplasm of the soft tissue, which is a lesion of uncertain pathogenesis, is uncommon and usually arises from the synovial tissue in joints and tendon sheaths. Rarely, extraskeletal osteochondromas also arise outside of synovial compartments. Most of the reported cases were presented in the hands and feet, especially in the fingers. Here we describe a 44-yr-old female patient who presented with a pain in the left buttock. A well-defined osseous mass was detected in the buttock. It consisted of sharply demarcated, mature hyaline cartilage that was covered with a fibrous capsule, which changed gradually into cancellous bone, more pronouncedly at the center. The diagnosis of an extraskeletal osteochondroma should be considered when a discrete, ossified mass is localized in the soft tissues. A case of pathologically proven extraskeletal osteochondroma of the buttock is presented with a literature review, magnetic resonance imaging, and radiological findings.

“…Though it does not involve bones, it may leave compression deformities or bone erosions. Radiographically discrete, irregular, ring like, or curvilinear calcifications are often seen [13,14]. ESCs are well demarcated, firm, rounded small masses, which seldom exceed 3 cms in greatest diameter [1].…”

“…ESCs are well demarcated, firm, rounded small masses, which seldom exceed 3 cms in greatest diameter [1]. Histopathologically, they can be diverse, ranging from a mature form with hyaline cartilage which is arranged in distinct lobules with fibrosis, or ossification or with myxoid areas, to an immature pattern with a pre-ponderance of chondroblasts [1,[13][14][15]. One thirds of them can display granular, floccular, or crystalline calcifications which can be focal or diffuse [1,[13][14][15].…”

“…In our case, few chondrocytes showed atypical nuclei and focal calcifications were seen. [ ESCs have to be differentiated from benign conditions like calcifying aponeurotic fibroma (CAF), tumoural calcinosis (TC), giant cell tumour of the tendon sheath (GCT), synovial chondromatosis (SC) [1,3,13,14]. More importantly, ESCs with cellular pleomorphism and myxoid changes have to be specially differentiated from ESMCSs which are malignant tumours that can metastasize, which require extensive surgery and post-operative radiotherapy [1,3].…”

A 58-year-old male presented to the Outpatients Department for a painless swelling of great toe of right foot, of six months duration. Physical examination revealed a well-defined, firm, fixed, swelling of 2x2 cms on the distal phalanx of great toe of right foot. X-ray of the mass showed a dense soft tissue mass, with no bone involvement. The same was excised and sent for a histopathological examination.Gross examination revealed a well-defined mass of 2x2 cms. Cut section showed a firm, whitish tumour with gelatinous and chalky white areas of calcification, which were covered by a piece of skin on one side [Table/ Fig-1].Microscopic examination showed structure of skin with a tumour in the dermis, which was arranged in lobules which were separated by fibrous septa [Table/ Fig-2,3]. There were islands of mature hyaline cartilage, myxoid areas and foci of granular calcification. Some of the chondrocytes showed atypical nuclei 4]. A histopathological diagnosis of an extraskeletal chondroma was made. DisCussionESC-Soft tissue chondroma is a rare benign cartilaginous tumour and nearly 80% of ESCs are found in the fingers and the rest is seen in hands, feet, toes and trunk [1][2][3][4][5]. Few cases are reported at rare sites like dura, larynx, pharynx, oral cavity, skin, fallopian tube and parotid gland [6][7][8][9][10][11][12]. Pathology Section aBstRaCtExtraskeletal Chondroma (ESC) is uncommon which occurs predominantly in hands and feet. It has a variable histology, with two thirds of the ESCs showing mature hyaline cartilage which is arranged in distinct lobules with fibrosis, or ossification, or myxoid areas and few showing immature patterns, with chondroblasts mimicking extraskeletal myxoid chondrosarcomas (ESMCSs). ESCs can recur but they never metastasize, whereas ESMCSs can metastasize, which require aggressive treatment.We are reporting a case of ESC which was located in the distal phalanx of right foot great toe in a 58-year-old male patient. The histopathology in our case showed features of ESC, with some foci showing myxoid stroma and few chondroblasts with atypical pleomorphic nuclei mimicking ESMCS. Hence, the case had to be carefully evaluated to exclude ESMCS and to make the diagnosis of ESC. The treatment was limited to simple excision of the tumour and extensive surgery and post operative radiotherapy were avoided.

Para-articular chondroma is a benign chondroid tumor which is frequently seen in the infrapatellar fat pad of the knee. We report a para-articular chondroma case located in the popliteal fossa which is very uncommon. Eighty-two-yearold male was presented to the department of orthopedics with a history of chronic pain and swelling at the popliteal fossa of his right knee. The patient was investigated using the following techniques; plain radiograph and MRI which gave an impression of a benign para-articular chondroma arising from the popliteal fossa. Radiographically, a welldelinated mass with spherical calcifications in the popliteal fossa was detected on the X-ray of the knee. On MRI, isointense signal intensity with adjacent muscles on T1-weighted TSE sequence and heterogeneous high signal intensities suggestive of chondroid matrix and oedema on fat-supressed T2-weighted sequence were detected. On postcontrast images peripheral enhancement in the chondroid lobules which was typical for chondroma was seen. After surgical resection, histopathological examination revealed para-articular chondroma.Keywords: Chondroma, soft tissue neoplasms, magnetic resonance imaging, knee. Öz Para
