Lipomas of the alimentary tract are rare tumours that can mimic malignant lesions. They are often small and asymptomatic although larger tumours can present with intusussception or as abdominal masses. We present a case of a transverse colon submucosal lipoma masquerading as a colonic adenocarcinoma leading to resection.A 74 year-old-man was referred urgently for assessment with altered bowel habits, and lower abdominal discomfort along with a positive Faecal-Occult-Blood sample. Colonoscopy demonstrated a large polypoidal lesion at the hepatic flexure with ulceration. Biopsies were inconclusive. A staging CT scan confirmed a 3.3 x 4.3 x 3.4cm Polyp with colonic wall thickening suspicious of malignancy. An extended right hemi-colectomy was performed. Histology showed a large submucosal lipoma with 12 reactive lymph nodes.Colonic lipoma often present as incidental findings detected on either imaging or endoscopically whilst investigating other symptoms. Their appearances can mimic colonic malignancy and surgical resection may be required.

We present a patient with sickle cell trait who suffered avascular necrosis of the maxilla as a complication of maxillary osteotomy. Understanding the blood supply of the maxilla and how possible patient related, anaesthetic and operative factors affect it, is important in understanding how the vascularity of the maxilla can become compromised in a surgical procedure. The perioperative parameters were analysed to identify any prognostic elements. Avascular necrosis of the maxilla is a rare complication of orthognathic surgery with few cases reported in the literature. There are identifiable risk factors that can influence the blood supply of the maxilla. Careful preoperative assessment is required to exclude patient factors that have the potential to affect tissue vascularity. This in conjunction with sound anaesthetic and surgical technique should all minimize the risk of avascular necrosis. Even so it is still possible for this rare complication to occur.

Laryngeal leishmaniasis is an extremely rare infection and is rarely reported in the UK. The ease of travel ensures that many tropical infections may present to UK clinicians.
