Primary retroperitoneal mucinous cystadenocarcinoma in pregnancy - case report.

INTRODUCTION: Primary retroperitoneal mucinous cystadenoma (PRMC) and its malignant variant - cystadenocarcinoma are extremely rare tumors known only from case studies and reviews. PRMC is a cystic tumor of the retroperitoneum, which remains asymptomatic for a long time and can reach significant proportions. It occurs mainly in women. CASE REPORT: We present the case of a 38-year-old healthy woman with diagnosed resistance in the right mesogastrium during a c-section. The delivery was terminated without a surgical intervention. The above mentioned resistance was examined further by ultrasound, computed tomography and magnetic resonance imaging. All imaging examinations showed a solid - cystic bilocular expansion, which looked like a mesenteric cyst in the right paracolic area. The patient was asymptomatic at all times, with only a palpable resistance of the abdominal wall. In November 2020, the patient underwent an elective surgery - extirpation of the cystic tumor and prophylactic appendectomy. The operation was performed classically, via midline laparotomy without perioperative perforation of the cystic tumor and without complications in the postoperative period. The histopathological examination showed a malignant variant of PRMC. So far, the patient remains free of any problems and is followed at the department of oncology. CONCLUSION: The goal of treatment is to achieve complete surgical removal of the tumor without its perioperative perforation. Due to the rare occurrence of the disease, there are no guidelines for the diagnosis and treatment of PRMC. Precisely because PRMC is a rare tumor, it should be part of the differential diagnosis of cystic tumors of the retroperitoneum, especially when young women are concerned.

Perforation of descending colon diverticulum by swallowed rabbit bone - a case report.

Authors present a case of a 58-year old pacient that underwent acute surgery for perforation of descending colon diverticulum by swallowed rabbit bone. The thesis focuses only on foreign bodies swallowed by adult patients. Comprehensive spectrum of foreign bodies that have entered the digestive tract in another way is omitted.

[Invagination in an adult as a rare cause of acute abdomen - 2 case reports]. / Invaginace u dospelého jako vzácná prícina náhlé príhody brisní - 2 kazuistiky.

The authors present two cases of intestinal invagination in adult patients. The first case is an 84-year-old polymorbid female patient indicated for acute surgical revision due to ileus with a finding of invagination in the sigmoid area, with no evidence of an organic cause. The second case, an 80-year-old polymorbid female patient, was indicated for acute surgical revision also due to ileus with a finding of invagination on the small intestine and with a proven neuroendocrine tumor. Unlike invagination in childhood where its cause is usually unknown[1,7], intestinal invagination is relatively rare in adults and it is mostly due to an organic cause, most frequently a benign tumor of the small intestine[2]. This study focuses on invagination as a rare cause of acute abdomen in adult patients.Key words: invagination - ileus - idiopathic.

[Abdominal actinomycosis - 3 case reports and literature overview]. / Brisní aktinomykóza - 3 kazuistiky a prehled literatury.

The authors present three cases of abdominal actinomycosis that were initially diagnosed as acute appendicitis, an abscess in the left groin and pelvic tumour, probably of gynaecological origin. Definitive diagnosis of abdominal actinomycosis was established as late as postoperatively. Abdominal actinomycosis is a chronic, infectious disease characterized most frequently by non-specific symptoms such as abdominal pain, fever, vomiting, bowel obstruction, weight loss, sometimes palpable resistance, and leukocytosis [1-9]. Diagnosis may be difficult and needs to be taken into account, especially in patients with risk factors.

[Laparoscopic appendectomy in pregnancy - a case report]. / Laparoskopická apendektomie u tehotných - kazuistika a prehled literatury.

The authors present a case of a 25- year- old pregnant patient diagnosed with acute appendicitis, indicated for laparoscopic appendectomy based on a consultation with gynecologists. No complications occurred during postoperative recovery and the patient was discharged on the fifth postoperative day, vital fetus with normal development. This case review points out a rarely discussed topic of laparoscopic appendectomy in pregnant women as a safe alternative to open surgery. Appendicitis is one of the most common indications for surgery during pregnancy. Appendicitis in pregnancy represents a challenge for a surgeon, both in terms of diagnosis as well as treatment and choice of surgical approach.
