Lipomas make up $4{\sim}5%$ of all benign tumors in the body and are most often located on shoulders and backs. Neck lipomas are often developed in the subcutaneous tissues of the posterior neck, Most lipomas have slow growth rate and the recurrence is very rare after surgical excision because of well-defined border. But lipoma originated from muscles(intramuscular and intermuscular lipoma), so called infiltrating lipoma, has ill-defined border and little or no evidence of encapsulation. Histologically the feature of infiltrating lipoma is distinctive. There is a consistent infiltration with dissociation of the surrounding muscle fibers. The overall recurrence rate is less than 5%, but rises to 62.5% when deep infiltrating lipomas are considered separately. Thus infiltrating lipoma is best excised with a margin of normal muscle to avoid recurrence. Its location in the head and neck is uncommon. 18 cases of infiltrating lipoma in the head and neck has been reported to date. Here we report a case of infiltrating lipoma that arises in the head and neck muscle with a review of the literature on the subject.

저자 등은 우측 측방 경부 및 이하부에 발생한 침습성 지방종을 가진 57세 여자 환자에서 이하선 천엽 절제술과 함께 외과적 절제술로 종물을 제거하였다. 술 후 약 2.5년 동안 추적 관찰한 결과 현재까지 재발 등 이상 소견 없이 기능적, 심미적으로 양호한 결과를 얻었기에 문헌고찰과 함께 보고함으로써 지방종의 진단과 치료에 도움이 되고자 한다.

Infiltrating lipoma is a rare mesenchymal neoplasm that, in spite of benign nature, characteristically infiltrates adjacent tissues and tends to recur after surgery. It has a predilection for the extremities and the trunk and is extremely rare in the head and neck region. We present a case of congenital infiltrating lipoma of the face, describing the intrabony invasion and osseous dystrophy as well as the soft tissue changes seen on plain radiographs and magnetic resonance imaging.

목적: 침윤성 근육내 지방종의 임상적, 생물학적, 방사선학적 및 병리 조직학적 특징들을 분석하여 정확한 진단과 치료 방침을 확립하는데 있다. 대상 및 방법: 1998년 10월부터 2001년 10월까지 본원 정형외과에서 침윤성 근육내 지방종으로 수술받은 후 5년까지 추시 가능한 환자 12예를 대상으로 하였다. 환자의 나이는 12세에서 63세까지로 평균 45.8세였다. 남자 4예, 여자 8예였으며, 종양의 위치는 상지 5예, 하지 3예, 배부 3예, 대둔부에 발생한 1예가 있었다. 모든 예에서 술전 단순 방사선 사진과 자기공명 영상 검사를 시행하였으며 수술시 획득한 조직에 대해 병리 조직학적 검사를 하였고 종양의 재발을 추시 관찰 하였다. 결과: 술전 방사선 검사상 골격근에 침윤을 보인 경우는 7예였다. 1예를 제외하고 11예에서 종양 조직과 침윤된 주변 골격근의 제거가 완전히 이루어졌고 수술시 얻어진 조직에 대한 병리조직학적 검사상 피막이 있는 3예와 피막이 없는 9예가 있었으며 지방 세포와 골격근 세포가 혼합된 7예가 있었다. 완전 제거가 불가능하였던 1예를 제외하고는 추시 관찰상 재발은 없었다. 결론: 침윤성 근육내 지방종은 침윤성으로 인하여 분화가 잘된 지방 육종으로 오진될 수 있으므로 병리 조직학적 검사를 통해 정확한 병리 조직학적 진단이 필요하며 술전 연부조직 단순 방사선 사진과 자기 공명 영상 검사는 종양의 정확한 진단과 위치 파악에 도움이 된다. 치료 방법으로 침윤성 근육내 지방종과 침윤된 근육을 충분히 절제하였을 때 재발없이 만족스러운 결과를 얻었을 수 있었다.

A 6-year-old female Chihuahua was presented to the Animal Medical Center for surgical resection of a perineal mass that had recently increased in size. Ultrasonography revealed a large, homogeneous fatty mass with irregular margins between the surrounding muscle layers due to infiltrating fatty tissues. Cytological findings from fine-needle aspirates revealed numerous sheets and clusters of adipocytes, which was consistent with the fatty mass. Based on ultrasonographic and cytological findings, an infiltrative lipoma was suspected. During the surgery, the perineal mass was found to be non-encapsulated, irregularly marginated, and extensively distributed into the surrounding muscles. The mass extended inside the pelvic cavity and left anal sac. The perineal mass was surgically removed and submitted for histopathologic examination. Histopathology confirmed that the mass was an infiltrative lipoma invading into the anal sac and surrounding muscles. The present report was an unusual presentation of infiltrative lipoma that invaded the anal sac in the perineum.

A 7 year-old male Maltese dog was referred to Seoul National University Veterinary Medical Teaching Hospital with a recurrent mass in the right scapular region. The patient had no pains associated with the mass. On aspiration cytology, the neoplastic mass is composed of clusters of mature adipocytes with large lipid vacuoles, intermixed with frequent microcapillary vessels which is characteristic of lipoma. At surgery, the mass was infiltrated into the surrounding muscles and therefore the complete resection of the mass was difficult. Histologically, the mass was diagnosed as infiltrative lipoma. The patient has no recurrent signs 8 months after surgery.

영남대학교 의과대학 성형외과학교실에서 흔히 사지의 골격근내에서 발생되는 intramuscular lipoma중 매우 드물게 관골부 근육에서 발생된 근육내지방종 1례를 치험하였다. 근육내지방종은 성숙된 지방세포가 위축되어 있는 근육속에 불규칙하게 생기는 양성종양으로 지방종의 완전절개만이 재발을 방지하고 완치 시킬 수 있는 유일한 치료방법이다.

Lipomas are the most common benign mesenchymal tumors composed of mature adipocytes. They are usually slow-growing, soft and asymptomatic masses. Angiolipomas are rare benign soft tissue tumors that are distinguished from common lipomas by a marked degree of vascularization. The diagnosis and prognosis of angiolipomas are based entirely on the findings of histological evaluations. Angiolipoma, showing characteristics of both lipoma and hemangioma, usually develop in the trunk and extremities, and rarely arise in the head and neck region. Angiolipoma of the cheek is very rare. This report presents the clinical and histopathological features of infiltrating angiolipoma excised from the cheek.
