Abstract

Adventitial cystic disease of the common femoral vein is a rare condition. We herein report the case of a 50-year-old woman who presented with painless swelling in her left lower leg that resembled deep vein thrombosis. She underwent femoral exploration and excision of the cystic wall. The presentation, investigation, treatment, and pathology of this condition are discussed with a literature review.

Abstract

A mesenteric cyst is defined as a cyst that is located in the mesentery of the gastrointestinal tract and may extend from the base of the mesentery into the retroperitoneum. A case report of a patient with mesenteric cyst is presented. In addition, a systematic review was performed of English language literature on chylous mesenteric cysts in adult humans. Of the 18 articles included in the review, there were 19 cases of chylous mesenteric cysts reported. Male to female ratio was 1.4:1 with a median age of 46 years. A preoperative diagnosis of mesenteric cyst was made in four patients based on computed tomography. All patients underwent surgery and there were no reports of recurrence on follow up. Chylous mesenteric cyst is a rare entity that needs to be recognized whenever a preliminary diagnosis of intra-abdominal cystic mass is made.

Abstract

Primary squamous cell carcinoma of the breast (SCCB) is a rare disease, with a worldwide incidence <0.1%. In many cases, it is clinically characterized by rapid growth. Cyst formation due to central necrosis of the tumor accompanies its growth of the tumor in approximately 60–80% of all cases. Furthermore, it is considered difficult to diagnose SCCB solely on the basis of findings from diagnostic imaging. For large intracystic tumors, mammotome biopsy or core needle biopsy (CNB) is rarely performed. Instead, fine-needle aspiration (FNA) targeted at the tumor inside the cyst is often performed. The accurate diagnosis rate of SCCB using FNA is lower than that for ordinary-type breast cancer. If the cyst is large, the solid tumor shadow outside the cyst behind or around the cyst may be masked or hidden by the large cyst, which can sometimes yield an unclear view of the tumor shadow or make it impossible to visualize the shadow. In the present case, the contents within the cyst were completely aspirated and collected during the first step (FNA), thereby yielding a clearer, complete view of the solid tumor located outside the cyst. Thus, the subsequent step (CNB) was able to be performed in a more accurate and reliable manner. The combined use of FNA and CNB proved to be useful in making a preoperative diagnosis of SSCB accompanying a cyst.
