Pulmonary sclerosing hemangioma (SH) is a rare tumor of the lung predominantly affecting Asian women in their fifth decade of life. SH is thought to evolve from primitive respiratory epithelium and mostly shows benign biological behavior; however, cases of lymph node metastases, local recurrence and multiple lesions have been described.

Pulmonary sclerosing hemangioma in a 21-year-old male with metastatic hereditary non-polyposis colorectal cancer: report of a case.

[Diagnosis of inguinal hernia].

A 56-year-old male presented to the emergency department with a feeling of heaviness and a protruding mass at the anal verge associated with pruritus in this area. The patient did not feel any pain and did not report experiencing faecal incontinence. Physical examination resulted in the visual diagnosis of a total rectal prolapse. Immediate manual repositioning through gentle pressure succeeded and the patient was scheduled for an elective laparoscopic ventral rectopexy.

We present a case of a combination of primary and secondary diaphragmatic hernia in a 63-year male patient. For progressive dyspnea and palpitations caused by a large and symptomatic Morgagni hernia resulting in a right-sided enterothorax, an open tension-free mesh repair was performed. The postoperative course was complicated by a secondary hepatothorax through a spontaneous rupture of the right diaphragm. Primary mesh repair of the Morgagni hernia, however, proved to be sufficient. This recurrent herniation might be a consequence of (1) preexisting atrophy of the right diaphragm caused by disposition and/or long-term diaphragmatic dysfunction due to the large hernia, combined with (2) further thinning out of the diaphragm by intraoperative hernia sac resection, and (3) postoperative increase of intra-abdominal pressure.

Upside-down stomach (UDS) is characterized by herniation of the entire stomach or most gastric portions into the posterior mediastinum. Symptoms may vary heavily as they are related to reflux and mechanically impaired gastric emptying. UDS is associated with a risk of incarceration and volvulus development which both might be complicated by acute gastric outlet obstruction, advanced ischemia, gastric bleeding and perforation.

The continuing controversy about surgery for non-colorectal non-neuroendocrine liver metastases (NCRNNE) necessitates identifying risk factors of worsened outcomes to improve patient selection and survival. Prospectively collected data of 167 patients undergoing hepatectomy for NCRNNE were analyzed, and a comparison to a matched population of colorectal liver metastases (CLM) was performed. Overall survival (OS) (35 vs. 54 months; P = 0.008) and recurrence-free survival (RFS) (15 vs. 29 months; P = 0.004) of NCRNNE patients were significantly shorter compared to those with CLM. The best survival was found in the genitourinary (GU; OS, 45 months; RFS, 21 months) NCRNNE subgroup, whereas survival for gastrointestinal (GI) metastases was low (OS, 8 months; RFS, 7 months). Patients with renal cell carcinoma (RCC) showed excellent outcomes when compared to CLM (OS, 50 vs. 51 months; P = 0.901). Extrahepatic disease (EHD) was identified as independent prognostic factor for reducing both RFS (P = 0.040) and OS (P = 0.046). The number of liver lesions (P = 0.024), residual tumor (P = 0.025), and major complications (P = 0.048) independently diminished OS. The degree of survival advantage by surgery is determined by the primary tumor site, EHD, the number of metastases, and residual tumor. Thus-even more than in CLM-these oncological selection criteria must prevail. GU metastases, especially RCC, represent a favorable subgroup.

Liver Resection for Non-colorectal Non-neuroendocrine Metastases: Where Do We Stand Today Compared to Colorectal Cancer?

CyberKnife radiosurgery (CK) is an effective tool for the treatment of malignancies. Its greatest potential is in high-dose radiosurgery delivered to targets in organs that move with respiration, e.g., liver tumors. For hepatocellular carcinoma (HCC), however, surgical treatment (resection, transplantation) is most likely to produce long-term survival; for non-resectable tumors, therapies other than radiosurgery are typically recommended. This study evaluated the long-lasting anti-tumor effects of CK combined with surgery in patients with HCC. MATERIALS AND METHODS : Eighteen patients (three women, 15 men) were included in this prospective observational study. They received 21 single-fraction CK treatments (26 Gy). Patient characteristics, treatment effects, tumor response (according to the Response Evaluation Criteria In Solid Tumors (RECIST) grading) and survival were measured for a median period of 29 months.
