An unusual site for hydatid cyst on ovary misdiagnosed as an ovarian cyst: a case report.

A hydatid cyst is a parasitic infection that can occur in multiple organs of the body, mostly in the liver. The ovary is one of the very rare locations for those cysts. Case presentation: The authors report a case of a 43-year-old woman with a primary hydatid cyst, the patient presented with left lower quadrant abdominal pain for 2 months. Ultrasound of the abdomen showed evidence of a multivesicular, fluid-containing cystic lesion in the left adnexa. The mass was excised and a hysterectomy with total left salpingo-oophorectomy was performed. Histopathology confirmed it to be a hydatid cyst. Clinical discussion: The clinical presentation of an ovarian hydatid cyst can differ, ranging from asymptomatic for years to dull pain if it compresses on the neighbouring organs or tissues, it may even cause a systemic immunological reaction if it ruptures. Conclusion: Cyst excision when possible is the best treatment, percutaneous sterilization techniques, and drug therapy may also be applied in certain cases.

Benign multicystic peritoneal mesothelioma (BMPM) presenting with ambiguous symptoms: A rare case report.

INTRODUCTION: Benign multicystic peritoneal mesothelioma (BMPM) represents a very rare clinical entity, with only 130 registered cases in the medical literature, therefore it is usually overlooked from the list of differential diagnoses. The treatment consists of surgery and other authors suggest complementing it with hyperthermic intraperitoneal chemotherapy. PRESENTATION OF CASE: A 25-year-old multiparous female experienced periodic abdominal discomfort for two weeks. She developed constipation, urinary urgency, and irregular menstruation. Family history was remarkable for endometrial and breast cancer. Abdominal examination revealed a palpable mass. Abdominal ultrasound and computed tomography scan identified the multicystic appearance of the mass. The diagnosis was unclear, therefore exploratory laparotomy was performed, which revealed multiple grape-like clusters of cysts that were excised immediately. BMPM was diagnosed based on the pathology report. Eventually, the follow-up did not reveal any recurrence. DISCUSSION: Mesothelial tumors include three pathological entities, including Benign multicystic peritoneal mesothelioma (BMPM). BMPM is an uncommon neoplasm and has a high recurrence rate after surgery. BMPM consists of clear cysts that take the shape of a grape-like cluster. Clinically, BMPM resembles a tangible abdominal mass and it is challenging to be diagnosed, due to its numerous differential diagnoses. CONCLUSION: The definitive diagnosis of intraperitoneal cystic masses is usually challenging. Therefore, BMPM -although very rare- should always be thought of when dealing with an intraperitoneal cystic mass, especially in women in the reproductive years. In our case cytoreductive surgery solely was sufficient to achieve a disease free follow up, however, further studies regarding treatment and follow-up are required.

A rare case of bowel intussusception due to adenocarcinomatous polyp in a 14 year-old child: case report.

BACKGROUND: Intussusception is a form of intestinal obstruction in which a segment of the bowel prolapses into a more distal segment. It is an uncommon condition in children older than 2 years and causes intestinal obstruction. On the contrary of adult intussusception, childhood intussusception does not usually happen on a lead point of a malignant organic lesion. CASE PRESENTATION: A 14-year-old male presented with complaints of heavy, bilious emesis and periumbilical colicky pain. Ultrasonography showed a dilated intestinal loop with absent bowel movement. CT scan revealed two masses in the abdomen. We performed an exploratory laparotomy that revealed invaginated intestines and showed a polyp near the area of interest. Necrotic segments and the polyp were removed and examined pathologically. Pathology showed adenocarcinoma in the polyp. After surgery, the general condition of the patient was normal and no complications occurred. CONCLUSIONS: Intussusception mainly occurs during infancy and early childhood. Mostly it is an idiopathic ileo-colic invagination. In our case, the patient had a jejuno-jejunal intussusception in his late childhood, and the lead point was an adenocarcinomatous polyp, which is rare in children. Amongst the many types of treatment, we chose surgical resection because of patient's age.
