Introduction: Cystic lesions in the renal pelvis may cause a diagnostic dilemma. These lesions may be benign or (pre)malignant and primary of secondary.
Case Report: A 65-year-old woman presents with a complex cystic mass in the lower pole of the left kidney measuring approximately 16 cm in size and classified as Bosniak type 2F with minimally thickened septa and thick calcifications on non-contrast-enhanced computed tomography. The histopathological findings are consistent with a mucinous cystadenocarcinoma in the renal pelvis. Given the absence of a primary focus and based on clinical and radiological examination, the diagnosis of a primary renal neoplasm is preferred.
Discussion: A review of the literature is performed to evaluate the histological differential diagnosis and confirm the diagnosis. Epidemiology with an overview of available similar cases since 2009, as well as etiological factors, treatment and prognosis was reviewed.
Conclusion: Primary renal mucinous cystadenocarcinoma is an exceedingly rare tumor. Histopathology still remains the gold standard for the diagnosis of this tumor. Because of the rarity, secondary involvement from more common sites, such as ovary and gastrointestinal tract, should be thoroughly excluded.

Rationale: Ovarian tumor torsion is a critical gynecological emergency, predominantly affecting women of reproductive age, with benign teratomas being the most common culprits. In contrast, malignant ovarian tumors, such as mucinous cystadenocarcinoma, infrequently present with torsion due to their invasive and angiogenic characteristics. The occurrence of torsion in malignant tumors complicates diagnosis and management, particularly when associated with complications like congestion, infarction, and internal bleeding.

Introduction: Mucinous ovarian cancer (MOC) is a rare subtype of epithelial ovarian carcinoma, comprising 3-5 % of all ovarian cancer cases. It typically affects women aged 20 to 50 years and is often diagnosed at an early stage, with most patients presenting with early-stage disease. However, giant mucinous cystadenocarcinomas are extremely rare and pose significant diagnostic and therapeutic challenges.

Introduction: Mucinous Cystadenocarcinoma (MCA) of the breast remains a relatively rare condition, and to date, there is no systematic summary of its imaging manifestations. Therefore, this report presents a detailed account of the diagnosis and treatment of mucinous cystadenocarcinoma in a 40-year-old woman, with a particular focus on imaging findings. Additionally, we conducted a comprehensive literature review on this disease and summarized its key imaging features.

Article Synopsis
- Appendiceal cancers, particularly mucinous cystadenocarcinoma, are rare and can cause serious complications like pseudomyxoma peritonei, leading to abdominal fluid accumulation called "jelly belly."
- A case of a young man with a persistent psoas abscess revealed mucinous adenocarcinoma with pseudomyxoma retroperitonei, emphasizing the need to consider malignancy in atypical abscesses.
- Early and accurate diagnosis is critical because these types of tumors can be misdiagnosed as common issues like abscesses, highlighting the importance of imaging and colonoscopy in identifying them.

Article Synopsis
- - A 51-year-old woman was diagnosed with a rare type of breast cancer called mucinous cystadenocarcinoma (MCA) after presenting with a mass in her left breast, which showed unique features in biopsies, including mucus secretion and papillary structures.
- - The tumor was identified as basal-like triple-negative breast cancer with mutations in several key genes, including TP53 and MUC6, as highlighted by immunohistochemistry and DNA analysis.
- - After 26 months of follow-up, the patient showed no signs of cancer recurrence or metastasis, indicating a potential for better understanding and treating this rare breast cancer type through this case study and literature review.
