Appendiceal mucocele is a rare disease that can sometimes mimic acute appendicitis or be discovered accidentally during surgeries. The clinical presentation of appendiceal mucocele is observed as lumen distension due to mucin accumulation. This condition has both benign and malignant underlying etiologies, which can be confirmed by histopathological examination. Acute presentation of appendiceal mucocele is rare and mostly resembles the symptoms of acute appendicitis. The treatment of appendiceal mucocele is crucial due to the risk of pseudomyxoma peritonei caused by the spread of mucus, mucocele perforation, or the presence of malignancy such as mucinous carcinoma. Surgical resection, either appendicectomy, typhlectomy, or sometimes right hemicolectomy, is the recommended management approach. This is a case of a 74-year-old male with pain in the abdomen as the major presenting complaint. He had a palpable right iliac fossa mass. The diagnosis of appendiceal mucocele was made by contrast-enhanced computed tomography, which was later confirmed by histopathology. The patient underwent surgical resection and was doing well at the three-month follow-up.

Craniopharyngiomas are rare benign neoplasms of epithelial origin. Usually located in the sellar and suprasellar regions, they typically present with symptoms of mass effect, raised intracranial tension, or endocrinological aberrations. Atypical presentations without these symptoms often delay diagnosis and worsen patient prognostic outcome, while timely diagnosis without these symptoms is essential for patient beneficence. Below, we present a case of an adamantinomatous craniopharyngioma in a 50-year-old female with minimal and non-specific symptoms. Radiographic imagining reported the presence of a cystic lesion in the sellar, suprasellar, and parasellar regions before the surgical excision. The patient was informed and a decision was made to undergo surgical resection of the mass lesion. The postoperative histopathologic study confirmed the neoplasm to be an adamantinomatous craniopharyngioma.

Idiopathic retroperitoneal fibrosis (IRF) is a rare condition characterized by fibrous tissue proliferation in the retroperitoneal space, commonly affecting the ureters and other abdominal structures. This case report describes a previously undocumented presentation of IRF in a 52-year-old female, who presented with recurrent gastrointestinal bleeding and severe anemia over six months. Diagnostic workup included endoscopy, colonoscopy, abdominal computed tomography (CT), and biopsy, revealing fibrous encasement of the mesenteric vessels leading to ischemic damage and gastrointestinal bleeding. Treatment involved high-dose corticosteroids and surgical resection of the fibrotic tissue, which resulted in complete resolution of symptoms. The aim of this case report is to highlight this unique presentation of IRF, discuss the diagnostic challenges, and explore effective treatment strategies for managing this rare but significant complication.

Intraventricular cardiac hemangiomas are very rare tumors that account for 5-10% of all cardiac tumors. We report a case of an asymptomatic 21-year-old young male who was incidentally detected with ventricular mass on echocardiography followed by magnetic resonance imaging. Surgical resection was done for confirmation and to avoid potential complications. Histopathology and immunohistochemical studies confirmed the diagnosis of a hemangioma of the ventricle. Subsequent regular follow-up has revealed no complications or recurrence, underscoring the favorable long-term prognosis. This case report highlights the importance of diagnostic evaluation even in asymptomatic individuals, allowing for early recognition and effective management of this rare cardiac entity.

UNASSIGNED: Pulmonary Artery Aneurysm is defined as the localized dilation of the pulmonary artery >1.5 times the upper normal limit or pulmonary artery measuring 4 cm. Pulmonary artery aneurysm is considered as a rare disorder having an incidence of 1 in 14,000 post-mortem examinations.
METHODS: Presented below is a case of a 28 year old gentleman, who presented with exertional dyspnea and orthopnea and was diagnosed with having a pulmonary artery aneurysm of 76 cm × 56 cm × 53 cm arising from the main pulmonary artery upon Computed Tomography Scan which is a rare finding according to the available literature.
UNASSIGNED: Clinical manifestations of pulmonary artery aneurysm are varying and rarely occur. However the use of radiological imaging has aided in the diagnosis. No specific treatment guidelines have been mentioned yet in the literature however, medical management, surgical resection and endovascular therapy are one of the multiple options available.
CONCLUSIONS: Pulmonary Artery Aneurysm presents with non-specific symptoms which makes the diagnosis very challenging for the physicians, in process, delaying the accurate management of the disease. However, pulmonary artery aneurysm must be considered as a differential diagnosis and appropriate management options, whether medical or surgical should be opted for keeping in mind the size and the complications of the disease.

Herein, we present two cases of isolated suprasellar dissemination of glioblastoma in patients with well-controlled primary lesions. A 22-year-old woman and a 56-year-old woman developed rapid growth of suprasellar glioblastoma dissemination 26 and 17 months after initial surgery, respectively. Both patients presented with acute visual impairment (decreased acuity and visual field disturbances) but lacked severe pituitary dysfunction. During surgery for the disseminated tumors, gross total tumor resection was difficult due to intraoperative findings suggesting optic pathway invasion. Both patients developed further intracranial dissemination within several months post-surgery. The presence of solitary sellar and suprasellar dissemination may indicate a terminal stage.

UNASSIGNED: Hepatic hemangioma is the most common type of benign mesenchymal liver tumor and often has a good prognosis. However, giant hepatic hemangioma larger than 10 cm is an unusual event, and accompanying symptoms of internal hemorrhagic necrosis are extremely rare. There are only a few cases reported.
UNASSIGNED: Herein, we report the case of a 52-year-old man with hemorrhagic necrosis of a giant hepatic hemangioma. The patient presented to the Department of Hepatobiliary Surgery with a complaint of distending pain on the right abdomen. The patient underwent hepatic artery embolization for giant hepatic hemangioma 2 weeks before presentation. During hospitalization, abdominal computed tomography revealed a mass (15.8 × 14.2 × 14.7 cm) with high density below the right lobe of the liver. The patient subsequently underwent irregular right hepatectomy with the guidance of three-dimensional visualization technology. The surgical anatomy confirmed the diagnosis of internal hemorrhagic necrosis. There was no recurrence or complications in a 4-month follow-up. Previous cases were reviewed to characterize the clinical features of giant hepatic hemangioma with internal hemorrhage necrosis.
UNASSIGNED: Cases of giant hepatic hemangioma with internal hemorrhagic necrosis are rare and usually only exhibit fever or epigastric pain. All patients in reviewed cases finally underwent surgical resection. Under these circumstances, the healing effect of transhepatic arterial treatment is not very satisfactory. Patients are deemed poor laparoscopic surgical candidates due to limited abdominal cavity. In order to standardize the diagnosis of these rare cares, the aggregation of existing and future case data is certainly warranted. If diagnosed, consideration should be given to implementing surgical resection according to patients\' condition by three-dimensional visualized technology.

Desmoid tumors are rare, benign, but locally aggressive fibromatoses that pose significant therapeutic challenges, particularly when located in the head and neck region. This report details the case of an extensive cervical desmoid tumor dependent on the levator scapulae muscle and involving the vertebral artery managed through surgical resection and intraoperative navigation. A 45-year-old male presented with a slowly growing cervical mass. Imaging revealed an 83x68x40 mm mass in the right lateral paravertebral space, dependent on the levator scapulae muscle and involving the vertebral artery. Biopsy confirmed a low-grade fusocellular myofibroblastic neoplasm consistent with a desmoid tumor. Given the poor prognosis associated with the symptomatic mass, surgical resection was performed using Brainlab intraoperative navigation (Brainlab, Munich, Germany). The procedure was successful, with preservation of vital structures and no evidence of recurrence postoperatively. Desmoid tumors in the head and neck region, though rare, require precise diagnostic and therapeutic approaches due to their aggressive nature and proximity to critical anatomical structures. The use of intraoperative navigation, in this case, facilitated accurate tumor resection, minimizing damage to surrounding tissues. Pathological analysis revealed a CTNNB1 gene mutation, specifically the S45P variant, which is associated with an increased risk of recurrence. This case highlights the importance of a multidisciplinary approach, incorporating advanced surgical techniques and genetic analysis, in the management of complex desmoid tumors. Intraoperative navigation proved invaluable in achieving successful surgical outcomes, underscoring its potential utility in similar cases. Continued follow-up is essential, given the potential for recurrence associated with desmoid tumors.

UNASSIGNED: Deep angiomyxoma (DAM) is a slow-growing benign tumor with high risk of local recurrence after surgical resection. Although DAM in a lower extremity is extremely rare, clinicians must be aware of its possible occurrence. Suspicion can be made based on clinical examination and radiological imaging but final diagnosis is confirmed on histopathological examination and immunohistochemistry. We intend to present an extremely rare case of DAM in the knee, managed successfully with marginal excision.
UNASSIGNED: A 4-year-old male child presented with the complains of a painless, progressively increasing, soft, non-tender, and fluctuant swelling in his right knee. The plain radiograph showed a non-calcified soft-tissue swelling and MRI revealed a multi-loculated cystic lesion with multiple septations. A pre-operative diagnosis of a benign cystic lesion was made. It was managed by marginal excision of the tumor and a histological diagnosis of DAM was made. IHC staining showed positivity for SMA, CD34 and vimentin were focally positive, while desmin and calponin were negative. At 12 months of follow-up, the patient had a normal painless gait and full knee ROM, without any local recurrence.
UNASSIGNED: DAM is a rare tumor which is often misdiagnosed. In this report, we present a rare case of benign cystic lesion which turned out to be DAM on HPE of resected specimen. Marginal excision of this lesion revealed good outcomes with no recurrence until 12 months of final follow-up. With this, we conclude that surgical excision should be the gold standard in cases of DAM.

A urachal remnant is a rare condition characterized by the persistence of the urachus beyond birth, often presenting with symptoms such as umbilical effusion, periomphalitis, and abdominal pain. Surgical resection is the cornerstone of treatment, but ensuring complete removal of urachal epithelium at the resection margin remains a challenge. This case report focuses on evaluating resection margins of urachal remnants and reports the case of a 25-year-old woman with complaints of umbilical effusion and a mass. She was diagnosed with a urachal remnant and underwent urachal resection and reconstruction, with postoperative confirmation of favorable outcomes and the absence of microscopic hematuria. The intraoperative examination did not reveal any macroscopically clear luminal structure of the urachal resection margin. Subsequent histopathological analysis of the margin using hematoxylin and eosin staining was challenging, prompting the use of immunohistological staining with keratin AE1/AE3 antibody. The antibody did not stain the urachal resection margin, confirming the complete removal of urachal epithelial components. Our study findings suggest the utility of keratin AE1/AE3 staining for assessing urachal remnant margins and underscore the importance of thorough evaluation and complete resection of urachal remnant to prevent recurrence and mitigate the risk of urachal cancer, contributing to improved surgical outcomes and patient care.
