Appendiceal mucocele is a rare disease, whose clinical symptoms resembles that of acute appendicitis, often diagnosed incidentally but can be asymptomatic. A correct preoperative diagnosis is very important in order to choose the right management and surgical tactic (appendectomy/ colectomy) to avoid dissemination and tumour recurrence.We report the case of a 54-year-old woman, presenting intermittent right iliac fossa pain for 8 months in a context of apyrexia and whose abdominal CT scan revealed an appendiceal mucocele. The surgical act was a right hemicolectomy with postoperative follow-up without particularity.

Heterotopia is defined as an ectopic localization of normal tissue; the heterotopia of the gastric mucosa can be observed all along the digestive tract. The localization in the gallbladder is exceptional. The diagnosis is histological, it may present some complications including ulceration and the risk of malignancy. We report the case of heterotopia of the gastric mucosa in the gallbladder while presenting the clinical, radiological and therapeutic features of this exceptional lesion.

Hydatidosis is a zoonotic parasitic infection that usually affects the lungs and liver but can occur in any organ. Peritoneal hydatidosis occurs in 5-16% of patients and can present with diverse clinical symptoms, often leading to misleading paraclinical exam results. Surgical intervention remains the primary treatment option, and prevention measures are implemented to protect susceptible populations. We present two cases of primary reshaped hydatid cysts mimicking digestive solid cystic masses, which were resected and found to be remodeled hydatid cysts on anatomopathological examination. The primary form of peritoneal hydatidosis is rare and can be confused with other cystic or pseudo-cystic masses of the peritoneum. Hydratic serology, while useful, is losing interest due to its delay in diagnosis, and surgery is the preferred therapeutic option. Recurrence is possible, making it necessary to implement preventive actions to interrupt the parasite's life cycle. Distant follow-up is necessary to monitor the patient's condition for up to 5 years.

Pheochromocytoma is a rare neuroendocrine tumour, developed at the expense of the chromaffin cells of the adrenal glands, which secretes in excess the catecholamines responsible for the major hemodynamic changes with cardiovascular complications [1]. The curative treatment of pheochromocytoma is based on surgery but requires preoperative preparation and conditioning of the blood pressure and specific postoperative monitoring [2].We report the case of a patient operated on for an enormous left adrenal pheochromocytoma, who had benefited from a left adrenalectomy whose immediate postoperative consequences were marked by the occurrence of severe left heart failure.

Spiegel's hernia, also known as lateral ventral hernia, is a rare entity of abdominal hernias due to a congenital or acquired defect in the abdominal wall anterior to the midline. The incidence is approximately 2% of abdominal wall hernias. It most commonly affects the elderly, and is more common in women. This hernia is secondary to certain factors such as collagen disorders, obesity, pregnancy, chronic cough. Diagnosis is often difficult due to its particular location, usually asymptomatic, but the risk of strangulation is significant. Abdominal ultrasound is useful, but a computerized tomography (CT) scan is the best imaging test to confirm the diagnosis with a highr sensitivity, allowing visualization of the muscle dehiscence and the content of the hernia sac. We report a case of an unstrangulated Spiegel’s hernia in an elderly man, treated surgically with a composite mesch under laparoscopy.
