It is very rare for LCH to occur exclusively in clavicle when it involves skeletal system. For diagnosis of LCH, sole imaging studies are inadequate, and histologic, immunochemical analyses are confirmative modalities. Treatment of LCH is not currently standardized. Most of the solitary tumorous lesions in clavicle in adults call for various differential diagnoses. LCH should be considered in the diagnosis of a adult patient with a clavicle mass.

Colorectal cancer can disseminate malignant cells to the peritoneal surfaces which over time progress to peritoneal metastases. Management of this type of metastatic disease has been approached using a combined treatment that consists of cytoreductive surgery and perioperative chemotherapy. To optimize these treatments a more effective chemotherapy that is used as planned part of the surgical procedure is required. Pharmacologic studies to initiate a new perioperative chemotherapy treatment were modeled after the successful systemic treatments of metastatic colorectal cancer referred to as FOLFOX. A management plan that included all of the essential features of successful systemic chemotherapy was formulated. Pharmacokinetic studies of 5-fluorouracil given both intravenously and intraperitoneally and oxaliplatin given intraperitoneally were investigated. The compatibility of 5-fluorouracil and oxaliplatin was documented showing no degradation of either drug when they were mixed in-vitro over 24 h. The pharmacokinetic analysis of hyperthermic intraperitoneal chemotherapy (HIPEC) with oxaliplatin showed cytotoxic concentrations for 120 min. In order to maximize oxaliplatin's effect, both intravenous
