Spindle cell lipoma with extramedullary haematopoiesis

Buffalo Hump: Spindle Cell Lipoma in Posterior Part of the Neck

“…Spindle cell lipoma (SCL) is rarely seen, and it shows uniform spindle cells and mature fat cells on histologic examination. It frequently arises in men between the ages of 45 and 65 years and is usually located in subcutaneous tissue in the upper parts of the back, shoulders, and posterior part of the neck 1,2 …”

“…It is a rare lipoma assigned into neoplasms originating from adipose tissue and characterized by uniform spindle cells and mature fat cells on histologic examination. Seventy‐five to 90 percent of the cases are men at the age of 45 to 65 years 1,2,4–6 . This benign lesion can be removed with local excision.…”

“…SCL can also be differentiated from malignant lesions in that it appears at certain ages, has long history, and can be cured with local excision 1,5 . CD34 may be positive in patients with SCL, but it does not help the diagnosis of the disease 1–4,6 …”

“…It frequently arises in men between the ages of 45 and 65 years and is usually located in subcutaneous tissue in the upper parts of the back, shoulders, and posterior part of the neck. 1,2 SCL is a slow-growing, soft, and solitary mass that does not cause tension or pain. [3][4][5][6] This report presents a case of SCL that looks like a buffalo hump and limits the movements of the neck.…”

“…Seventy-five to 90 percent of the cases are men at the age of 45 to 65 years. 1,2,[4][5][6] This benign lesion can be removed with local excision. Clinical and morphologic features of SCL may be similar to those of pleomorphic lipoma.…”
