Paragonimiasis infestation is endemic mostly to Asia, Africa and South and Central America and commonly found in the lung. It is extremely rare in soft tissue.
A case of paragonimiasis occurred in a 66-year-old woman who presented with a left, painful, 2-cm-diameter breast mass and had a history of eating uncooked freshwater crabs. On mammography, an ill-defined, round, isodense mass was detected without calcification. Hemorrhagic material was aspirated by fine needle aspiration (FNA) of the breast mass, which contained many parasitic eggs. They were about 90 microns long, ovoid, yellowish brown, transparent and thick shelled, with a flattened operculum at 1 end. The breast mass was completely excised. Many collapsed eggs of Paragonimus infiltrated the lobules and fibroadipose tissue, with accompanying abscess formation. To confirm the diagnosis, serologic testing for paragonimiasis was performed; it was positive for Paragonimus antibody.
Paragonimiasis very rarely presents as a breast mass and can be diagnosed by FNA.
肺吸虫病主要流行于亚洲、非洲以及南美洲和中美洲，常见于肺部。在软组织中极为罕见。
一名66岁女性患肺吸虫病，其左侧乳房出现一个直径2厘米的疼痛性肿块，有食用生淡水蟹的病史。乳房X线摄影显示，发现一个边界不清的圆形等密度肿块，无钙化。通过对乳房肿块进行细针穿刺抽吸（FNA）获取了血性物质，其中含有许多寄生虫卵。这些虫卵长约90微米，呈卵圆形，黄褐色，透明，壳厚，一端有扁平的卵盖。乳房肿块被完整切除。许多塌陷的肺吸虫卵浸润小叶和纤维脂肪组织，并伴有脓肿形成。为确诊，进行了肺吸虫病血清学检测；肺吸虫抗体呈阳性。
肺吸虫病极少表现为乳房肿块，可通过细针穿刺抽吸进行诊断。
