Case Reports
Expression of hormone receptors in low-grade adenosquamous carcinoma of the breast: A case report.
Low-grade adenosquamous carcinoma (LGASC) is a rare subtype of metaplastic breast carcinoma which is generally recognized as a characteristic subgroup of triple-negative breast cancers previously. However, in this study, we reported for the first time a case of LGASC with hormone receptors expression. ⋯ We herein report the first case of LGASC with immunoreactivity for hormone receptors, expanding its profile of immunophenotypes. CD44v may play an important role in the transition of LGASC precursor lesions into malignant processes, which may serve as a therapeutic target in LGASC.

Vascular Ehlers-Danlos syndrome (vEDS) is a rare autosomal dominant inherited collagen disorder caused by defects or deficiency of pro-alpha 1 chain of type III procollagen encoded by COL3A1. vEDS is characterized not only by soft tissue manifestations including hyperextensibility of skin and joint hypermobility but also by early mortality due to rupture of arteries or vital organs. Although pulmonary complications are not common, vEDS cases complicated by pneumothorax, hemothorax, or intrapulmonary hematoma have been reported. When a patient initially presents only with pulmonary complications, it is not easy for clinicians to suspect vEDS. ⋯ To the best of our knowledge, both cryptorchidism and PCH-like foci have never been reported yet as complications of vEDS, suggesting our case might be a new variant of this condition. This case emphasizes the importance of comprehensive physical examination and history-taking, and the clinical suspicion of a possible connective tissue disorder when we encounter cases with atypical presentation and/or unique chest radiologic findings especially in young patients.

Case Reports
Osteopoikilosis found incidentally in a 17-year-old adolescent with femoral shaft fracture: A case report.
Osteopoikilosis is a rare and asymptomatic disease of the bone, which is often discovered occasionally on radiography for irrelevant complaints. Characterized by multiple, small, circular, or oval-shaped radiodense lesions, it may be confused with bony metastatic tumors. ⋯ Although this case is not so complicated, we have to be cautious when differentiating osteopoikilosis and bony metastases in clinical practice in future, which should avoid causing undue distress to both the patients and doctors.

Currently, the treatment of hepatocellular carcinoma (HCC) associated with portal vein tumor thrombosis (PVTT) is a challenge. Percutaneous puncture endovascular placement of iodine-125 (I) seeds strand and stent is reported to treat HCC with tumor thrombus effectively. However, it is proved to be only suitable for the main portal vein (MPV) thrombus. ⋯ A Y-configuration stent makes it possible to treat tumor thrombosis in portal vein branches (PVBs). However, the long-term curative effects of Y-configuration stents need to be verified.

Calcifying fibrous tumor (CFT) is a rare benign soft tissue mesenchymal neoplasm. Although the gastrointestinal (GI) tract is the most common predilection site of CFT, the clinicians, even including pathologist, generally consider it as GI stromal tumor (GIST) or other submucosal tumors such as schwannoma and leiomyoma. ⋯ We present a case of gastric CFT, which was misdiagnosed as GIST based on endoscopic and radiologic findings.
