我們報告一例罕見的海綿狀淋巴管瘤發生在一名五十五歲男性腸系膜上。病患到院主訴為腹痛，理學檢查發現彌漫性腹痛，抽血檢查顯示白血球上升，電腦斷層檢查看到下腹部小腸腸系膜附近有一巨大腫瘤。病患接受手術切除一段約67公分長的小腸，小腸腸系膜在外觀上呈現腫脹與海綿樣，顯微鏡下顯示為一腸系膜海綿狀淋巴管瘤，它是由大大小小的薄壁淋巴管所組成，管腔內還聚集一些淋巴球。免疫組織化學染色檢查證實此淋巴管瘤覆蓋的內皮細胞呈現D2-40陽性。後續追蹤這病患並沒有腫瘤覆發的情況。

We report a case of mesenteric lymphangioma in a 55-year-old man suffered from progressive abdominal pain. While neutrophilia was observed from the hemogram, his physical examination showed diffuse abdominal tenderness. A massive and lobulated mass measuring 23 cm x 21 cm in size at lower abdomen, and pelvic cavity involving dilated bowel and mesentery were shown in computerized tomogram. The man received an operation where a segment of small intestine measuring 67 cm in length was excised. The mesentery showed marked swelling and soft and fluctuant palpation. Sponge like multicystic structure was also found on cut surface. Microscopic examination showed a mesenteric cavernous lymphangioma characterized by multi thin-walled and dilated lymphatic vessels lined by a flattened endothelium and frequently surrounded by lymphocyte aggregation. Immunohistochemical examination found D2-40 The lining endothelial cell was found to be positive for D2-40 from. The man experienced no tumor recurrence in the following years.
