A 37-year-old woman was referred to our institution for further management of a mass lesion located in the thoracic cavity. The mass had grown by more than 10 cm over the course of a year and was initially considered to be a scar from previous pulmonary tuberculosis at another hospital. The patient had complained of left-sided flank pain for a year and experienced dyspnea for one month. Chest radiography and chest computed tomography revealed an irregular-shaped mass in the left mid to lower pleural cavity. The mass was widely excised through left thoracotomy. Pathologic examination of the biopsy specimen revealed a malignant spindle cell tumor, which consisted of components of osteosarcoma, pleomorphic sarcoma, and leiomyosarcoma. The patient underwent adjuvant chemotherapy and has been doing well without any evidence of recurrence for 14 months.

Background: Osteomas are benign, slow-growing bone tumors that can be classified as central, peripheral, or extraskeletal. Central osteomas arise from the endosteum, peripheral osteomas from the periosteum, and extraskeletal osteomas within the muscle. Frontal peripheral osteomas are mainly encountered in plastic surgery. In this study, we retrospectively analyzed the clinical data of patients with frontal peripheral osteomas. Methods: We retrospectively reviewed the medical records of patients who visited our hospital with frontal peripheral osteomas between January 2014 and June 2022. We analyzed the following variables: age, sex, tumor type (sessile or pedunculated), single or multiple, size, history of head trauma, operation, and recurrence. Results: A total of 39 patients and 41 osteomas were analyzed, of which 29 osteomas (71%) were sessile and 12 osteomas (29%) were pedunculated. The size of the osteomas ranged from 4 to 30 mm, with an average size of 10 mm. The age of patients ranged from 4 to 78 years with a mean age of 52 years. There were seven men (18%) and 32 women (82%), and the man-to-woman ratio was 1:4.6. Two patients (5%) had multiple masses, with two osteomas in each, while only two patients (5%) had a history of head trauma. Twenty-nine patients (74%) underwent ostectomy by a direct approach, and none of the patients experienced recurrence. Conclusion: The epidemiologic data of our study will help plastic surgeons encounter frontal peripheral osteomas in the field to provide proper management for their patients.

유잉육종계열의 종양은 뼈와 연부조직에 발생하는 악성 소원형청색세포종양이다. 골격외 유잉씨 육종은 드문 악성 종양으로 연부조직에 발생한 유잉육종의 한 형태이며, 소아와 젊은 성인에서 호발한다. 흉폐부위에 발생한 골격외 유잉씨 육종은 임상적으로 만져지는 종괴나 통증으로 나타난다. 골격외 유잉씨 육종이 앞가슴벽을 침범한 경우에는 유방 종괴로 나타날 수 있으나, 이러한 보고는 드물다. 저자들은 22세 여성에서 유방 종괴로 나타난 앞가슴벽에 발생한 유잉씨 육종의 증례를 보고한다. 초기의 초음파에서 이 거대 종괴는 유방에서 발생한 종괴로 오인되었으나, 추가적인 전산화단층촬영 및 자기공명영상에서 종괴는 흉벽에서 기원하였음을 알 수 있었다. 영상의학과 의사는 골격외 유잉씨 육종의 영상 소견을 알고, 흉벽의 병변이 임상적으로 유방 병변으로 오인될 수 있음을 이해하는 것이 중요하다.

Myositis ossificans is a solitary benign ossifying lesion in the soft tissue. Occurring predominantly in muscles, a similar lesion may occasionally be found in subcutaneous tissues, tendons, fascia and periosteum. It is often misdiagnosed as an extraskeletal osteosarcoma because of its rapid growth. Therefore, it is sometimes called pseudomalignant myositis ossificans. Myositis ossificans rarely occurs in the distal portion of the finger. We present a case of myositis ossificans of finger and review the the clinical, radiographical, and histological presentation, as well as the appropriate therapeutic management.

Osteoma is a benign osteogenic tumor composed of cancellous or compact bone, classified as peripheral, central, or extraskeletal. Peripheral osteomas are uncommon. Excluding the maxillary sinuses, the maxilla is a rare site for osteomas. The purpose of this report was to describe clinicopathological and radiological features of two peripheral osteomas occurring in the jaws, one located in the mandible and another in the edentulous maxillary alveolar ridge. The tumors were asymptomatic and were fully excised without any complications or recurrence. The lesions were submitted to histopathological analysis and diagnosed as peripheral osteoma, compact type.

A 16-year-old female Poodle with multiple mammary masses was referred to the Veterinary Medical Teaching Hospital of Seoul National University. Radiographic finding indicated a round mass of soft tissue density at the ventral portion of the 4th-7th sternum, which was 7 cm in diameter and presented multiple mineralization within the mass. Cytologically, aspirate of the mammary mass was moderately cellular and revealed well-differentiated osteoblasts with moderately basophilic cytoplasm, various sized and eccentrically placed nuclei and distinct nucleoli. Osteoblasts interspersed with osteoid-suspected pink-staining intercellular matrix. Some cells displayed malignant features such as macronuclei, macronucleoli, binucleation, abnormal mitotic figures, anisocytosis and anisokaryosis. On which the mass was diagnosed as osteosarcoma. Histopathologic examinations of the mass were compatible with a diagnosis of osteosarcoma. The patient was treated with surgery alone. The patient died 45 days later from surgery.

Soft tissue sarcomas are malignant tumors that arise in the extraskeletal connective tissues of the body. And the clinical behavior of soft tissue sarcomas is characterized by a tendency to extensively invade surrounding soft tissues as well as early metastatic dissemination. Difficulties were encounted when soft tissue sarcomas invade the major vessels. There are a few reprots about the reconstruction of the major vessels after resection of soft tissue sarcomas. We have treated 3 cases of the soft tissue sarcomas involving the major artery. After marginal excision of the tumor mass, the involved major artery was reconstructed with Gortex artificial vessel graft and we could salvage the patient's extremity.

Langerhans' cell histiocytosis is a rare disease showing proliferation of histiocytes in multiple organ system. Bone lesions are the most common radiolologic manifestation of Langerhans' cell hysticytosis. Extraskeletal sites of Langerhans' cell hystiocytosis involvement include the skin, lymph nodes, thymus, lungs, central nervous system, liver, pancrease, spleen, and bowel. The authors have experienced a case of Langerhans' cell histiocytosis which involved the skull. A 3-year-old female presented with soft tissue mass on right periorbital area. Plain skull X-ray showed punched out bone lesion. Computed tomography showed non-enhancing osteolytic lesion on right frontal skull. Histologic findings of an excised mass revealed pathologic features of Langerhans' cell histiocytosis.

Chronic kidney disease (CKD)-mineral and bone disorder (CKD-MBD) is a common complication of CKD, often accompanied by extra-skeletal calcification in adult patients. As increased vascular calcification is predicted to increase cardiovascular mortality and morbidity, the revised Kidney Disease: Improving Global Outcomes guidelines recommend avoiding calcium-containing phosphate chelators. However, extra-skeletal calcification is less commonly noticed in pediatric patients. Here, we report our experience of such a complication in pediatric patients receiving maintenance peritoneal dialysis. Extra-skeletal calcification was noticed at the corneas, pelvic cavity, and soft tissues of the lower leg in 4 out of 32 patients on maintenance peritoneal dialysis. These patients experienced the aggravation of extra-skeletal calcifications during peritoneal dialysis, and 2 of them underwent excisional operations. It is required to monitor extra-skeletal calcifications in children on kidney replacement therapy.
