IntroductionLiposarcoma is the most commonly diagnosed soft tissue sarcoma in adults and occurs predominantly in the lower limbs and retroperitoneum. Primary mediastinal liposarcomas are rare.They are often asymptomatic and when growing to large size the presenting symptoms are related to direct invasion or compression of other thoracic organs such as the heart, great vessels and lung.Case presentationA case of a 68-year-old man with primary mediastinal liposarcoma involving the diaphragm and pericardium and successfully managed by complete surgical excision is presented. The patient's postoperative course was uneventful with no evidence of recurrence 9 months after the operation.ConclusionSurgical removal is the optimal treatment for a mediastinal liposarcoma. If the entire tumor can not be resected, surgical debulking often results in symptomatic relief. International literature has demonstrated that recurrent disease occurs and therefore a long-term careful follow up is required.

IntroductionSupraglottic laryngeal cysts are benign, uncommon lesions that have the potential to cause airway compromise.Case PresentationWe present a case of a 46-year-old Caucasian woman who was scheduled for excision of a large neck growth (saccular cyst) and was managed successfully. There was thorough consideration regarding anesthetic and surgical management. Steps taken led to a successful excision with no recurrence during follow up.ConclusionThis case was an opportunity to consider the challenges in the airway management associated with such cysts and provided reassurance that excision of these cysts is associated with a good post-operative outcome.
