An unusual zoonotic parasitic disease causing a breast mass: Breast hydatid cyst

Abstract

Case presentation A 68-year-old woman presented with a right breast mass of 6month duration, which was gradually increasing in size. Physical examination revealed a 10-cm mass in the upper outer quadrant of the right breast. This mass was firm, oval, non-tender, and free from the skin and underlying tissue. A medio-lateral mammogram revealed a homogeneous, dense, well-circumscribed lesion in the right breast (Figure 1). An axial computed tomography scan of the thorax showed a hypodense, well-defined mass with a capsular wall of 7 cm containing endogenous daughter cysts (Figure 2). Intraoperatively, an encapsulated breast mass with no adhesions was found. A surgical excision was performed. Histopathological

A case report of abdominal wall hydatidosis: An uncommon location

“…The rarity of this localization could be explained by the difficulty of developing the parasitic embryo in the subcutaneous fat which constituted an inadequate condition for embryophore development [4] . However, It could occur via arterial infusion [5] . The evolution of the subcutaneous hydatid cyst could be marked by several complications: fistula, infection, and compression of neighboring structures [6] , [7] .…”

A case report of primary multiple hydatid cysts of psoas muscle: An exceptional location

“…The rarity of this localization could be explained by the difficulty of developing the parasitic embryo due to lactic acid production secondary to muscle contractility, which constituted an inadequate condition for embryophore development [3] . Psoas muscle involvement is often primary and occurs via arterial infusion, rarely secondary to an adjacent complicated hydatid cyst [5] . The evolution of the psoas muscle hydatid cyst could be marked by several complications: peritoneal fistula, infection, hydronephrosis and compression of neighboring structures [6] , [7] , [8] , [9] .…”

Preoperative predictive factors of liver hydatid cyst occult or frank intrabiliary rupture

“…The source of infection is equivocal, but it is most likely from E. granulosus eggs passed in the feces of wild dogs [2] . This parasitic disease could affect any organs [3,4] . It affects essentially the liver.…”
