Opis:
Background: A case of congenital abdominal dumbbell fashion neuroblastoma with invasion of the spinal canal detected by ultrasonography (US) is presented. Case report: A 3-week-old male neonate was admitted to the hospital with a palpable mass in the left lumbar region. Ultrasound examination was performed on the same day. It disclosed a pathologic mass filling the left side of the retroperitoneal space - displacing laterally and inferiorly the left kidney. The second part of the tumor was located above the Gerot's fascia in the muscles and infiltrated the spinal canal via lumbar intervertebral foramens. Computer tomography scanning confirmed the presence of solid masses in these locations. Urinary excretion of vanillin-mandelic acid (VMA) was within normal range, ferritin level was elevated (447 μg/ml). Bone scintigraphy showed metastases to the left clavicle. There were no changes in bone marrow. Diagnosis of an undifferentiated malignant neuroblastoma was established in histopathological examination. Conclusions: Spinal ultrasonography is highly recommended in neonates and infants with retroperitoneal tumors

Opis:
Solid pseudopapillary neoplasms (SPN) are an extremely rare form of tumor with low malignant potential that are generally located in the tail of the pancreas. The prevalence of SPN has increased with the recent advancement in radiological imaging. Contrast-enhanced computed tomography of the abdomen and endoscopic ultrasound-guided fine needle aspiration are excellent modalities in preoperative diagnosis. Surgery is the main treatment modality of choice; a successful R0 resection is curative. We present a case of SPN along with an up-to-date summary of the literature in order to provide a reference for the management of this rare clinical entity

Opis:
Schwann cell tumours are a rare group of benign neoplasms that origin form peripheral nerves. 0.1%–1.5% develops in the larynx causing hoarseness, difficulty swallowing and dyspnoea. The treatment of choice is surgical resection of the tumour during open type surgery or endoscopic procedure. The chosen surgical technique depends on tumour location, size observed in clinical examination and imaging. Also, clinical manifestation of the disease is included in the decision-making process.

Opis:
BACKGROUND: Neuroendocrine neoplasms (NEN) are rare neoplasms that originate from neuroendocrine cells and are characterized by the potential of hormonal activity. Approximately 70% of these tumours are located in the gastrointestinal system (GI), followed by the bronchi, endocrine glands-like C cells of the thyroid (medullary carcinoma), the parasympathetic and sympathetic system (paragangliomas, pheochromocytoma) and other very rare locations. The prevalence of cerebral metastases in neuroendocrine tumours is estimated by various authors to be approximately 1.5-5%. When the primary tumour is located in the pancreas, it is associated with a risk of cerebral metastases lower than 2%. CASE REPORT: We describe a patient with a disseminated pancreatic NEN that presented with an isolated lesion in the brain. We gathered the important data via medical history,, observation, analysis of medical records, imaging and others diagnostic tests. Despite the fairly rare prevalence of cerebral metastases in NENs, a neurological work-up should be performed. This should include neuroimaging of the brain, preferably with MR, together with the somatostatin receptor scintigraphy (SRS), in each clinically suspicious case. A histopathological examination of the CNS tumour can confirm a dedifferentiation of NEN in the direction of a neuroendocrine carcinoma (NEC - neuroednocrine carcinoma) with a poor prognosis. CONCLUSIONS: Cerebral metastases are diagnosed in 1.5-5% of patients with a neuroendocrine neoplasm. In each case suggestive of a dissemination into the central nervous system, MRI of the brain should be performed.

Opis:
Introduction: Detection of the frequency of pancreatic cystic lesions has increased in the recent years. The majority are pseudocysts, the remaining cysts are mainly neoplasms. Proven risk of malignancy affects intraductal papillary mucinous neoplasms (IPMN) and mucinous cystic neoplasms (MCN). The aim of this study was to analyze clinical data of patients with pancreatic cysts or pancreatic cystic neoplasms on operate at Department of General and Transplant Surgery in the Barlicki Hospital in Lodz. Material and methods: In 2007-2016, there were 145 patients operated on at the Department of General and Transplant Surgery in Barlicki Hospital in Lodz, due to pancreatic cystic lesion. The type of operation, histopathological diagnosis and basic demographic data were analyzed. Results: Non-neoplastic cyst (mainly pseudocysts) was found in 66.9% of patients, neoplasms were detected in 33.1%. The mean age was significantly higher in patients with neoplasm than without neoplasm (57.06 years vs. 50.88 years, p=0.009). Neoplastic cyst occurred more frequently in women (68.75% of women, 31.25% of men, p=0.001). Malignant tumor was found in 14.58% of neoplasms cases and in 4.83% of all pancreatic cystic lesions. Conclusions: According to the analyzed material, there is a significant risk of malignancy in patients with pancreatic cyst. Neoplastic cysts are more common in women. Discussion: Pancreatic cystic tumors are treated mainly by resections of pancreas. In case of benign lesions with low risk of malignancy, there are less extensive operations performed, such as enucleations of lesions. There are no guidelines that could be used satisfactorily in follow up of patients with pancreatic cysts.

Skeletal metastasis from carcinoma of the gall bladder : need for bone scintigraphy justified?
Autorzy:
Hira, Priya
Aswani, Yashant
Opis:
BACKGROUND: Carcinoma of the gall bladder has a guarded prognosis with predominant sites of involvement being liver and regional nodes. Osseous metastasis in carcinoma of the gall bladder is rare and hence bone scintigraphy does not form a part of the routine work-up for such patients. CASE REPORT: We describe two patients with carcinoma of the gall bladder with osteolytic metastasis (stage 4). Conservative treatment was planned but both of them succumbed to the illness. CONCLUSIONS: We thus highlight the importance of performing a bone scan or PET CT in cases of carcinoma of the gall bladder. Besides, our cases challenge Paget's seed - soil theory for sites of metastasis.
