Background: Compression of the ulnar nerve at the level of Guyon’s canal is a very rare compressive neuropathy. Due to the vast range of symptoms that can manifest depending on the degree of ulnar nerve compression, the clinical picture is not consistent. Objective: The aim of the study is to outline the diagnostic techniques and therapeutic options. Case report: We reported a case of ganglion cyst-induced compression of the ulnar nerve in Guyon’s canal. A 45-year-old female patient underwent surgical ulnar nerve release in Guyon’s canal at the Clinic for Plastic and Reconstructive Surgery. Discussion: After a thorough medical history and physical examination, the diagnosis of the syndrome is made, and ultrasound and magnetic resonance imaging (MRI) testing are used to determine the origin of the neuropathy. A ganglion cyst was identified pathohistological one month following the surgical excision of the soft tissue tumor. In order to hasten the patient’s nerve recovery, physical therapy was recommended, and the patient was monitored for the following two years. After two years of treatment, the patient has made a very good recovery of the functionally damaged hand, as determined by a modified Bishop scoring method for evaluating functional ulnar nerve recovery. Conclusion: In virtually all cases, early surgical intervention can lead to an outstanding functional recovery. If the symptoms are more severe and continue or get worse for more than three months, early surgical intervention is the gold standard for treating Guyon’s canal syndrome. If soft tissue formations are compressing the ulnar nerve in Guyon’s canal, MRI is thought to be the gold standard for diagnosis.

Introduction: Timely diagnosis is a prerequisite for the successful treatment of malignant skin tumors. Late diagnosis leads a patient into a situation of losing valuable time and chance for cure. Material and methods: A prospective study was conducted from February 2006 until August 2011 which analyzed the reasons that led to establishing the diagnosis of malignant skin tumors in 220 patients. Patients were divided into two groups: Group A (102 patients), patients with diagnosed melanoma, and group B (118 patients) of patients suffering from basocellular (BCC) and planocellular cell (PCC) skin cancer. Parameters for comparison of analysis results were the reasons for coming to examination and reasons for not coming to the examination, because of which skin cancers were not diagnosed in time. Goal: To determine the factors that influences the establishment of late diagnosis and treatment of skin tumors. Results: It was confirmed that the prejudices of patients that tumors of the skin „should not be operated because it is dangerous“ is the main reason for late diagnosis. At the same time it is confirmed that the belief that it is unnecessary to operate congenital changes of the skin is the second most important reason for delayed diagnosis of malignant skin tumors.
