“…The clinical differential diagnosis includes other tumor-like lesions, such as salivary gland tumors, fibromas, lipomas, neural tumors, giant cell tumors, and soft tissue cysts ( 4 , 5 ). If soft tissue calcification and bone formation are observed, the differential diagnosis should include teratomas, osteomas, calcified lymph nodes, osseous hamartoma, calcified hamartomas and osteolipomas ( 6 , 7 ). When the lesion is located close to the foramen caecum, the lingual thyroid nodule should be considered.…”

“…Osseous choristomas are rare benign lesions characterized by ectopic bone formation in the soft tissue of the head and neck region ( 1 , 2 ). They occur more frequently in the lingual region, and there is a variety of the differential diagnosis including the lesion of hard tissue in soft tissue ( 3 – 7 ). Dermoscopy is a non-invasive diagnostic method that allows an in vivo assessment of morphologic features, which are not visible to the naked eye ( 8 ).…”

Osseous choristomas are rare benign lesions characterized by ectopic bone formation in the soft tissue of the head and neck region. Dermoscopy visualizes the morphological characteristics that are not observable by the naked eye, and may be used for the evaluation of calcification under the skin. The present study reports a case of an osseous choristoma arising in the tongue, and reveals the dermoscopic features of osseous choristoma from a surgical specimen. A 7-year-old boy was referred to the Department of Dentistry and Oral Surgery, with an asymptomatic pedunculated mass in the tongue. The lesion was removed completely with the adjacent normal tissue under general anesthesia. Dermoscopy of the surgical specimen revealed the hypovascular and homogeneous pattern of the lesion with round extruded whitish material. Based on dermoscopic findings, the presence of calcified hard tissue in the submucosa was verified by the dermatologist. Radiographic examination of the surgical specimen revealed the lesion contained a radiopaque trabeculated mass. Histologically, the lesion contained an osseous tissue, and the pathological diagnosis of osseous choristoma was made following consideration of the ectopic bony tissues that were localized away from the maxillo-mandibular bone. The postoperative course was uneventful with no signs of recurrence during the 36 months following surgery. To the best of the author's knowledge, this is the first report of evaluation of osseous choristoma using dermoscopy. The observation indicates the usefulness of dermoscopy for the diagnosis of oral ossified lesion in oral soft tissue.

“…The differential diagnosis depends on tumor location. In the submental area, others benign tumors composed of bone tissue include teratoma, tumor calcinosis, ossifying fibroma, central hemangioma, myositis ossificans, and soft tissue sarcomas (lipossarcoma, synovial sarcoma, osteossarcoma, and chondrosarcoma) [5,16]. Because of the wide spectrum of lesions located in this region, imaging exams are critical to establish a precise diagnosis.…”

a b s t r a c tLipoma is the most common benign mesenchymal soft tissue neoplasm in adults. It is rarely seen in the oral cavity and comprises 1-4% of all benign oral lesions. There are different types of lipomatous tumors that contain other predominant mesenchymal elements such as cartilaginous/osseous tissues. Osteolipoma is a rare histopathologic variant of lipoma accounting for less than 1% of all lipomatous cases. Eight cases of this type of lipoma were reported in the mandibular buccal vestibule. The present study aims to report a rare condition: a patient with osteolipoma situated in the mandibular region. In addition, a literature review is presented.
