“…Other symptoms included abdominal pain, abdominal mass, weight loss, nausea or vomiting obstipation, and change in bowel habits. In the emergency setting AM can also be presented as intestinal strangulation, appendiceal intussusception, or generalised abdominal pain [ 5 , 19 , 20 ]. Approximately 30% of patients may present with perforated appendicitis or extravasation of mucus during surgery and this can result in pseudomyxoma peritonei [ 10 ].…”

Appendiceal mucocele is a rare cause of acute abdomen. Mucinous appendiceal neoplasms represent 0.2–0.7% of all appendix specimens. The aim of this study is to report a case of a mucinous appendiceal neoplasm presented as acute appendicitis, discussing the clinical and surgical approach in the emergency setting. A 72-year-old female patient was admitted to the emergency department with a clinical examination indicative of acute abdomen. The patient underwent abdominal computed tomography scan which revealed a cystic lesion in the right iliac fossa measuring 8.3 × 5.2 × 4.1 cm, with calcified walls, and a mean density indicative of high protein content. The patient was taken to the operating room and a right hemicolectomy was performed. The postoperative course was unremarkable. The histopathological examination revealed a low-grade mucinous appendiceal neoplasm with negative regional lymph nodes. Ultrasound and CT are useful in diagnosing appendiceal mucocele and synchronous cancers in the emergency setting. The initial operation should include appendectomy and resection of the appendicular mesenteric fat along with any fluid collection for cytologic examination. During urgent appendectomy it is important to consider every mucocele as malignant in order to avoid iatrogenic perforation causing pseudomyxoma peritonei. Although laparotomy is recommended, the laparoscopic approach is not contraindicated.

“…Benign appendiceal mucinous neoplasms are more common than the malignant variant, and accounts for 63-84% of the cases [6]. These lesions present as appendiceal enlargement with features of epithelial villous adenomatous changes with atypia [7].…”

The most common epithelial tumor affecting the cecal appendix is mucinous neoplasm. Malignant mucinous neoplasms of the appendix are rare entities, often asymptomatic. Low-Grade Appendiceal Mucinous Neoplasms (LAMN) are most often clinically silent. One of the rare causes of acute abdomen is appendiceal mucinous neoplasm, representing only 0.2-0.7% of all appendectomy specimens. These tumors are discovered incidentally either during a survey or at the time of surgery for other causes. Mucinous neoplasms of the appendix carry a complex diverse group of neoplasms ranging from simple mucoceles to complex pseudomyxoma peritonei. We present a rare case report of a 27 year old female, who was admitted to the surgical emergency with severe pain and tenderness in the right abdomen for 3 days. Emergency laparotomy with appendectomy was performed and based on the histopathological findings; a diagnosis of low grade appendiceal mucinous neoplasm (LAMN) was given. Our patient has recovered completely postoperatively and is well after 6 months of follow up period.

“…Cu excepția valorii de diagnostic, colonoscopia poate servi și ca opțiune de tratament [33]. Deci, invaginarea apendicelui vermiform poate fi diminuată în timpul colonoscopiei la insuflarea aerul [21] sau poate duce la o reducere totală a acestuia [24], rezultând o regiune eritematoasă asemănătoare unui halou care înconjoară lumenul apendicular [94]. Prin urmare, colonoscopia este un examen indispensabil pentru diagnosticul diferențial [55].…”

Appendiceal intussusception (AI) is an unusual and rarely reported clinical entity. It was first described by McKidd in a 7-year-old boy in 1858. Since then the literature on it has been confined to a few case reports and very small cases series, in totally about 300 cases being published. Because of variations of clinical symptoms and lack of pathognomonic sign, rarety of the pathology and diversity of causing factors, accurately detection of the presence or absence of appendiceal pathology is difficult. However, imagistic and endoscopic methods may be useful in AI detection and play a large and important role in differential diagnosis. Treatment of AI differs significantly depending on underlying pathological condition, benign or malignant.
