Schwannomas are neuroectodermal tumors that rarely occur in the retroperitoneal space. We report two cases of patients who presented with abdominal pain. Radiological findings revealed a retroperitoneal mass in both cases. Both patients underwent complete surgical excision with an uneventful postoperative course. The histopathological study confirmed the nature of schwannoma. Complete surgical excision remains the gold standard for the management of these tumors. The preoperative diagnosis is usually difficult; however, the definitive diagnosis is made upon histopathological examination.

Struma ovarii is an extremely rare type of ovarian teratoma distinguished by the unusual presence of thyroid tissue. It is usually a benign condition; however, malignant transformation is sometimes detected. The diagnosis relies on histopathological examination and is infrequently made on routine investigations. We report two cases of struma ovarii: one benign and the other malignant. The first case involved a 27-year-old woman who underwent a right ovarian cystectomy for an incidental ultrasonographic finding of a solid right adnexal mass. The diagnosis of a benign struma was made after histopathological study. The second case involved a 68-year-old woman who underwent a right salpingo-oophorectomy for a right ovarian bulky mass and the histopathological diagnosis was consistent with that of a malignant struma. We examine the challenges involved in the diagnosis and management of this rare entity.

Scar endometriosis is an uncommon type of extra-pelvic endometriosis. However, it should be suspected in any woman of childbearing age complaining of a cyclic, painful nodule in a scar from a previous obstetric or gynecologic procedure, after excluding other differential diagnoses. The treatment of choice is surgical resection. We report two cases of scar endometriosis that appeared in two young ladies after cesarean sections, discovered by a parietal mass near the cesarean scars.

Gallbladder tuberculosis (GT) is an extremely rare disease entity, even in our country Morocco known for being an endemic area. The lack of pathognomonic clinical presentation and radiological features of GT makes preoperative diagnosis unlikely and poses a diagnostic dilemma regarding gallbladder carcinoma (GC). The diagnosis is usually made by histological examination after cholecystectomy, highlighting the importance of sending every gallbladder specimen to pathology. We report an exceedingly rare case of GT mimicking GC and refer to a recent review of the literature to discuss the clinical and radiological features of GT.

Introduction: Hydatid disease (HD) is a parasitic pathology that remains endemic in Morocco and poses a public health problem. Its location in the psoas muscle is a rare entity. We report this case highlighting the diagnostic challenges, therapeutic modalities as well as prognosis. Case Presentation: We report the case of a 40-year-old male patient without a notable pathological history, referred to our department for management of a paravertebral hydatid cyst mass with fluid density and scalloping on the verteral body on thoraco-abdomino-pelvic computed tomography scan. After a pretherapeutic assessment, the patient underwent an exploratory laparotomy which objective a deep right laterovertebral mass. The patient underwent a resection of the protruding dome, lavage using hydrogen peroxide and drainage of the residual cavity. The patient recovered well and was discharged 5 days later on albendazole 10 mg/kg/d. The anatomopathological analysis of the specimen confirmed the diagnosis of hydatid cyst. The evolution was satisfactory for the patient with a recall of 6 months. Discussion: Hydatidosis is an anthropozonosis caused by the larval form of Echinococcus granulosus. It can reach the psoas muscle by great circulation. The diagnosis of HD in the psoas is often difficult. Biology and imaging confirm the diagnosis and the standard treatment remains surgery. Conclusion: HD of the psoas is a rare entity. The diagnosis is based on biology and imaging, and radical treatment is surgery.

Squamous cell carcinoma (SCC) of the colon is a rare malignant tumor occurring as either a primary or secondary lesion. Few cases of metastatic or secondary colonic SCC have been published. We report an unusual case of a 59-year-old female patient who was treated by Wertheim hysterectomy and adjuvant chemoradiation for stage IIB SCC of the uterine cervix. Two years later, she developed a metastatic location in the caecum causing an acute intestinal obstruction. She underwent an emergency open right hemicolectomy with ileocolic anastomosis and resection of two nodules of the umbilicus and the right parietal peritoneum. Histopathological examination confirmed a triple metastatic location of SCC. She is disease-free 11 months after surgery. We discuss the clinicopathological features, management strategies, and the prognosis of this rare entity.
