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.

Intramuscular lipomas are benign adipose tumors of the soft tissues that may resemble liposarcomas because of their size, deep location, and occasionally infiltrative growth. An awareness of their existence is fundamental to treating them correctly, and their differential diagnosis from liposarcoma is essential. Magnetic resonance imaging (MRI) is a useful diagnostic tool to differentiate benign adipose tumors from liposarcoma. Marginal excision and biopsy are required for the definite diagnosis and the treatment of symptomatic intramuscular lipomas. To the best of the authors' knowledge, this is the first report in South Korea regarding the treatment of an intramuscular giant lipoma of the ankle.
