Retroperitoneal Schwannoma

Schwannoma - a tumor growing from Schwann cells of the peripheral nerve sheath. Retroperitoneal schwannoma is a rare tumor accounting for approximately 1 to 5% of all retroperitoneal neoplasms. Retroperitoneal localization occurs for a total in 0.75-2.6% of cases, often they localize in the extremi- ties, the head and neck. Despite the significant progress made currently in the field of instrumental studies for non-organ retroperitoneal tumors, diagnosis and differential diagnosis remain a complex problem requiring further study. Presented clinical case illustrates difficulties in the diagnosis of retro- peritoneal schwannoma. Precise preoperative determination of the tumor relationship with all the nearby organs and vessels according to the different methods of ray diagnostics gives an opportunity to define the tactics of treatment.

Nerve Sheath

Malignant peripheral nerve sheath tumor (MPNST) is a rare tumor that can develop on the lining of nerves and within the network of nerve fibers in different organs, and it is commonly found in the head and neck, limbs, and trunk. These tumors can occur in patients of any age. They most commonly occur in adults aged 20 to 50 years; however, fewer cases of this tumor in children have been reported. To date, no neonatal case of MPNST in the nasal cavity has been reported. Here, we report the case of a 4-day-old female newborn who presented with a nasal mass that re-enlarged after surgery and was diagnosed as MPNST of the nasal cavity on the basis of pathological results. This is the first report of MPNST in the nasal cavity of a neonate. Differential diagnosis and treatment of nasal masses have been proposed in the related literature.

SummaryWe present two case reports concerning patients who had to undergone surgical treatment according tp the diagnosis of thrombophlebitis with insufficiency of the greater saphenous vein and putative encapsulated haematoma in the lower left leg area. During the operation we found tumours with urgent suspicion of malignancy. The histological examination revealed the diagnosis of mesenchymal chondrosarcoma and malignant peripheral nerve sheath tumour which are extremely malignant, but very rare neoplasmas with unfavourable prognosis. Conclusion: Since both types of tumours are often located below the knee, phlebotomists and vascular surgeons should take them into account as differential diagnosis.

Acute disseminated encephalomyelitis (ADEM) is a rare immune-mediated inflammatory and demyelinating disorder of the central nervous system. Its characteristic perivenular demyelination and inflammation aid in the differential diagnosis with other inflammatory demyelinating diseases. Here, we present a clinical case of ADEM, summarize its histological hallmarks, and discuss pitfalls concerning the most important neuropathological differential diagnoses.

Abstract We describe a case of urachal adenocarcinoma arising in a 30-year-old woman. The patient underwent partial cystectomy. Three years later, she presented with an isolated metastasis to a thoracic vertebra, which was treated by vertebral corporectomy. Histologic findings are described, and the clinical findings, management, and metastatic patterns of this rare tumor, as well as the differential diagnosis on a biopsy specimen, are discussed.

21-hydroxylase (21-OH) is the main antigen of the adrenal cortex, so the determination of antibodies (Ab) to 21-OH can help in the diagnosis and prognosis of chronic primary adrenal insufficiency (CPAI). Purpose of the study: evaluation of the relevance of Ab to 21-OH for the diagnosis and prediction of autoimmune CPAI. Materials and methods of research: the study consisted of three blocks: 1) assessment of the specificity and sensitivity, as well as the prognostic potential of Ab to 21-OH in patients with polyglandular autoimmune syndrome (APS) – individuals with APS type 1 with and without CPAI (n=106); 2) assessment of the dynamics of the level of Ab to 21-OH – patients with autoimmune CPAI were included (n=41); 3) assessment of the significance of Ab data for the differential diagnosis of various forms of CPAI, including patients with CPAI and APS type 1 exclusion (n=30). The study of Ab to 21-hydroxylase was performed using enzymelinked immunosorbent assay (BioVendor kits, Czech Republic). Results: statistically significant differences were obtained in the frequency of detection of Ab to 21-OH in patients with or without PCNI (p<0,001). The sensitivity of the method was 96%, specificity was 75%, a positive predictive value was 90%, and the negative predictive value was 89%. In 83% of patients, the level of Ab decreased with time (median size decreases – 20,4%/year). An inverse relationship was also found between the level of Ab and the duration of the course of CPAI (R=–0,460, p<0,001). In a group of 30 patients with CPAI and with exclusion of APS type 1, 21 were found to have Ab to 21-OH, only one of them had a monogenic non-autoimmune cause of CPAI (a mutation in the MC2R gene). Monogenic forms of CPAI were found in another 7 patients (mutations were found in the DAX1 and ABCD1 genes), among them an increase in Ab to 21-OH was not detected. Conclusion: determination of Ab to 21-OH is a specific and sensitive method for the diagnosis of autoimmune CPAI. An increase in Ab to 21-OH is a risk marker of autoimmune CPAI development.
