Lipoma is a rare cause of ulnar nerve compression in Guyon's canal. All four previously reported cases from 2000 to 2009 have been accurately diagnosed on MRI. We present a case report where the MRI and surgical findings differed and a summary of the previous cases in the literature. We conclude that although MRI remains the best investigation for this condition, it is not always accurate and clinical findings still provide the best basis for surgical treatment.
Squamous cell carcinoma (SCC) is a malignant tumour arising from the keratinising cells of the epidermis. It is slow growing, locally invasive and has the potential to metastasise to other organs of the body. We report an unusual presentation of a rapidly enlarging, well-differentiated SCC on the upper lip of a 75-year-old woman. Rapidly enlarging skin lesions in specialised areas pose great challenges in its management. As the lesions increase in size, they eliminate first-line reconstructive options that can compromise functional and aesthetic outcomes. Accurate histological diagnosis prior to surgery is paramount, as it bears significance to the excision margins. Early, urgent referral to a specialist unit is essential and may avoid the need for more invasive procedures and associated morbidity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
