Benign fibrous histiocytoma (BFH) is a rare benign primary skeletal tumor that occurs commonly in the long bones, spine and pelvis. BFH constitutes a diagnostic challenge because it shares clinical background, radiological characteristics, and histological features with other fibrous lesions such as non-ossifying fibroma, giant cell tumor. We present a case of BFH with cystic change that occurred in the distal femur. We did not identify any case of BFH with cystic change involving the majority of the lesion that occurred in the metaepiphysis of the long bone.

Fibrous histiocytomas are commonly occurred in the skin of the extremeties and rare in the head and neck region. Fibrous histiocytomas in general are considered benign tumors. But deep fibrous histiocytomas have more poor prognosis than cutaneous counterparts and tendency of local invasion and recurrence. Wide surgical excision is the treatment of choice due to high recurrence rate and potential malignancy. We presented a rare case of benign fibrous histiocytoma occurred in the superficial lobe of the right parotid gland, showing palpable mass with pain.

Benign fibrous histiocytoma (FH) is a benign tumor composed of fibroblasts and histiocytes in varying proportions. This tumor is usually found in adult extremities but rarely occurs in deep soft tissues of the oral cavity. As it is difficult to diagnose with physical and radiologic exams, deep benign FH can only be diagnosed by histopathology. We report a case of a 36-year-old female patient who came to our department with painless swelling in the right buccal mucosa. This case report reviews the clinical, radiological, and histological aspects of this tumor.

Benign fibrous histiocytoma is characteristically composed of fibroblastic and histiocytic cells. Most commonly, this tumor occurs in the dermis and superficial subcutis, but it is uncommon in the knee. We experienced a case of deep benign fibrohistiocytoma in a 38-year-old woman who complained of palpable tender mass on the medial aspect of the right knee. MR imaging findings included a well-delineated oval mass with low signal intensity on T1-weighted and high-signal intensity of T2-weighted images, as well as a marked peripheral contrast enhancement. Histopathologically, the lesion contained a mixture of fibroblastic and histiocytic cells that were often arranged in a cartwheel or storiform pattern and accompanied by varying numbers of inflammatory cells, foam cells, and siderophages. After surgical removal of the lesion, no recurrence was observed.

Benign fibrous histiocytoma(BFH) is a mesenchymal cell-originated tumor composed of cells with fibroblastic and histiocytic differentiation. BFH occurs predominantly on sun-exposed skin of extremities. Oral BFH lesions are uncommon. The majority of oral lesions includes the soft tissue but not the jaw bones. The lesion appears as well-defined multilocular radiolucencies associated with bony swelling when it occurs on the jaw. The lesion induces the thinning and expansion of the cortex and shows many thin, indistinct septa in the lesion. Surgical excision is the choice of treatment. The recurrence rate is low and metastasis has not been reported. We report the clinical, radiographic and microscopic findings of a BFH case occurred in the mandible with literature reviews.

슬관절에서의 양성 섬유성 조직구종은 매우 드문 질환으로 우연히 발견되는 경우가 많고, 가장 호발하는 부위는 수지 및 완관절과 족지 및 족관절의 건초나 활액막에 발생하는 것으로 알려져있다. 조직학적으로 병변의 위치에 관계없이 유사한 소견을 보이고 대부분은 특별한 증상이 없으나 관절운동 제한, 동통 등의 동반증상이 발생하며 치료는 절제술만으로도 충분하다. 저자들은 슬개하 지방체와 활액막 사이에 발생한 양성 섬유성 조직구종의 1례를 치료 경험하게되어 진단적 관절경 검사 시행 후 변연부 절제수술을 시행하여 병변을 치유하였다. 수술 후 24개월의 추적 관찰상 재발은 없었으며 또한 슬관절 기능도 만족할만 하였다.

슬관절에서의 양성 섬유성 조직구증은 매우 드문 질환으로 대부분의 경우 통증 등의 특별한 증상을 유발하지 않고 심부에 위치하고 있어 진단을 놓치기 쉬우며 우연히 발견되는 경우가 많다. 저자들은 슬관절의 운동제한과 동통을 주소로 내원한 53세 여자 환자에 대해서 외관상 촉지 되지 않았다가 MRI 검사에서 슬개건 하부의 종물을 발견하였고, 진단적 관절경 검사 후 절제 및 조직 생검 결과 양성 섬유성 조직구종으로 밝혀진 1예를 경험하게 되었다. 심부 양성 섬유성 조직구증은 모든 양성 섬유성 조직구증의 5% 이하로 흔하지 않은 것으로 알려져 있는 가운데 슬관절에서 발생한 1예에 대해서 문헌고찰과 함께 보고하고자 한다.

Undifferentiated pleomorphic sarcoma (UPS) in the mandible region is a rare malignant neoplasm. We encountered the case of a patient who had been diagnosed with deep benign fibrous histiocytoma (DBFH) prior to surgery, but the final biopsy revealed the presence of tumor tissues in the resected margin, which indicated a UPS. Therefore, radiotherapy was conducted post-operatively, but the tumor recurred approximately 3 years later and a second surgery was performed. The difference between the initial and final diagnoses was considered to be due to the characteristics of the tumor, as it involved both benign and malignant components. DBFH and UPS can occur in young women. DBFH can transform to a malignancy and UPS may also appear as a benign tumor during early biopsy. Hence, attention should be paid to diagnosis and treatment methods, and ongoing close observation is required.

42세 남자 환자가 종합 검진상 발견된 좌측 6번 늑골의 후궁(posterior arc)의 종괴로 내원하였다. 흉부 컴퓨터 전산화 단층 촬영 및 뼈 스캔(bone scan)에서 뼈연골종(osteochondroma)으로 의심되었고, 흉강경하 늑골 절제술을 시행하였다. 수술 과정 중 혈관 및 신경 손상은 없었다. 환자는 수술 후 4일째 합병증 없이 퇴원 하였다. 조직학적 결과는 양성 섬유성 조직구종(benign fibrous histiocytoma)이었다. 본 증례를 통하여 흉강경을 이용한 늑골의 절제는 후측방 절개술을 통한 늑골 절제술에 비해 미용적인 면에서 장점이 있으며, 손쉽게 수행 가능함을 알 수 있었다.

A 45-year old woman with congestive heart failure due to left atrial tumor was operated on. Three tumor masses arising from posterior wall, atrial septum, anterior portion of mitral valve were resected. Pathological diagnosis was malignant fibrous histiocytoma [MFH]. Above one case and sixteen previous reports are reviewed. Eleven cases out of 17 were females. The tumors all originated primarily in the left atrium and 8 had distant metastases. The metastatic sites are lung [4 cases], brain [2 cases], liver, jejunum, cervix and pleura etc. Careful pathologic study is necessary to differentiate the uniformly fatal MFH of the heart from the more common benign atrial myxoma. The treatment modalities are surgical resection, chemotherapy, and radiation therapy & the prognosis of intracardiac MFH is poor. We underwent partial resection of left atrial MFH and obtained symptom relief and patient still alive 7 months post-operatively in state of NYHA class II.
