It is very important to make accurate and early diagnosis to reduce both the rate of negative laparotomy and the morbidity and mortality associated with acute appendicitis. Numerous scoring systems have been described in the diagnosis of acute appendicitis. We aimed to determine the accuracy rates of these scoring systems in the diagnosis of acute appendicitis by applying Alvarado, Eskelinen, and Ohmann clinical scoring systems to patients who underwent appendectomy. This study was performed on patients who underwent appendectomy for acute appendicitis at Baskent University Alanya Hospital and Alanya Alaaddin Keykubat University Education and Research Hospital between September 2017 and December 2018. The sensitivity and specificity of Alvarado, Eskelinen, and Ohmann scoring systems as well as the compatibility analysis of scoring systems with pathology results were investigated. A total of 554 patients undergoing appendectomy were included in the study. The sensitivity of Eskelinen scoring method was found to be 53.4%, the specificity was 68.1%; the sensitivity of Alvarado scoring method 41.6%, the specificity 79.7%; and the sensitivity of Ohmann scoring system 94.0%, the specificity was 8.7%. In conclusion, Ohmann scoring system has the highest sensitivity; it could be more efficient in exclusion of the appendicitis diagnosis due to its low specificity. It is also concluded that some clinical parameters that are scored in Eskelinen and Alvarado scoring systems may decrease the sensitivity and specificity of these methods depending on the patient population and atypical clinical presentations.
Metachronous Occurrence of Granular Cell Tumor in Breast Skin and Scalp: Diagnostic Challenging Differentiating Benign from Malignant and a Literature Review

Granular cell tumor (GCT) is a Schwann cell related benign neoplasm of soft tissue. GCT is an uncommon entity that occurs in a wide variety of body sites, but it is generally presented in the skin, oral cavity, superficial soft tissue, and respiratory and digestive tracts. Most of the GCTs are benign but clinically and radiologically these may mimic malignancy. Histopathological diagnosis is gold standard for establishing the true nature of the lesion. GCT is most commonly solitary but in about 10% of cases can be multifocal, usually involving various skin and soft tissue sites versus involving various internal sites. Therefore, these can involve skin and soft tissue or submucosa and viscera. GCT is usually benign; however, local recurrence is common due to incomplete removal. Malignant cases are rarely reported in 1-2% of cases. In this study, we report clinical and histopathological findings of a 36-year-old woman with metachronous GCT in breast and scalp. The clinical features raise the question of whether these are metachronous benign GCTs or whether this is establishment of malignant behavior. The aim of this report is to present the histopathological and clinical features of GCT and the diagnostic challenge of differentiating benign from malignant GCT.
