Abstract Primary glioblastoma develops de novo without clinical or histological evidence of a low-grade precursor lesion, while secondary glioblastoma develops from a low-grade glioma. The same IDH mutation is observed in almost secondary glioblastomas that occurs in low-grade gliomas with IDH mutation. Present report is an extraordinary case of secondary glioblastoma, IDH-wildtype arising in diffuse astrocytoma, IDH-mutant. A 31-year-old female presented with seizure 3 months ago, who had a history of operation for diffuse astrocytoma, IDH-mutant on the left frontal lobe 6 years ago. Magnetic resonance imaging test revealed new infiltrative lesions (6.5cm) in left frontal lobe and corpus callosum, in addition to the non-enhancing mass (3.4cm). New infiltrative lesion suspected anaplastic change and the patient underwent tumorectomy. Microscopically, non-enhancing lesion showed high cellularity, moderate nuclear atypia and brisk mitosis. Microvascular proliferation and necrosis were absent that can be diagnosis as anaplastic astrocytoma. However, new infiltrative lesion showed microvascular proliferation and necrosis that acceptable for diagnosis as glioblastoma. IDH-1 immunohistochemistry (IHC) was positive in anaplastic astrocytoma but negative in glioblastoma. In addition, we assessed NGS based on the SNUBH Brain v1.0 (Macrogen, Seoul, South Korea) panel. Similar to IHC result, IDH-1 (p.Arg132His) mutation was found in anaplastic astrocytoma but not in glioblastoma. Interestingly, ATRX (p.Gln1670Ter) and TP53 (p.His193Arg) mutations were found in both lesions. Additionally, PTEN (p.His296Pro) mutation was identified in glioblastoma component only. Until now, it is well-known hypothesis that the IDH mutation initiated in glial progenitor cell and the other genetic mutations occur sequentially in pathogenesis of secondary glioblastoma. Notably, this is the first case report that other genetic alterations can be initiated before IDH mutation contrary to previous hypothesis. In our case, mutation of ATRX and TP53 might be initiated, and PTEN and IDH-1 mutations were sequentially occurred in glioblastoma and anaplastic astrocytoma, respectively.

AbstractFibrosarcomas are malignant tumors of the connective tissue, which are characterized by proliferation of fibroblasts. Most of these tumors are localized subcutaneously and cause different symptoms depending on their location. The case report describes a dermal tumor on the outside of the pinna in a 7-year-old female Cashmere goat. The tumor was surgically removed and histopathological examination revealed a low grade fibrosarcoma. Although tumors are rare in ruminants because of the animals’ short lifespan (age of slaughtering in most cases < 24 months) in modern production processes, they should be considered as a differential diagnosis.

Dose Radiation

Abstract Background As molecular advances have deepened the knowledge on low-grade glioma (LGG), we investigated the effect of higher radiation dose on the survival of IDH-wildtype (IDHwt) LGG. Methods In the current study, 52 IDHwt LGG patients who received radiotherapy were enrolled from the Chinese Glioma Genome Atlas dataset. Radiation doses > 54 Gy were defined as high-dose, whereas doses ≤ 54 Gy were defined as low-dose. We performed univariate and multivariate survival analyses to examine the prognostic role of high-dose radiotherapy. Results In total, the radiation dose ranged from 48.6 Gy to 61.2 Gy, with a median of 55.8 Gy, and 31 patients were grouped into high-dose radiation. Univariate survival analysis indicated that high-dose radiotherapy (p = 0.015), tumors located in the frontal lobe (p = 0.009), and pathology of astrocytoma (p = 0.037) were significantly prognostic factors for overall survival. In multivariate survival analysis, high-dose radiotherapy (p = 0.028) and tumors located in the frontal lobe (p = 0.016) were independently associated with better overall survival. Conclusions In conclusion, high-dose radiotherapy independently improved the survival of IDHwt LGG. This can guide treatments for glioma with known molecular characteristics.

A 13 years old boy admitted with the complaint of progressive exophthalmos and gradually decreasing vision on right eye, also occasional headache and deformity on the right fronto-orbital region. Radiological & clinical findings revealed a case of frontal osteoma in the right frontal sinus extending up to right frontal lobe, eroding right roof of the orbit. Complete excision of the tumor mass was possible surgically. Biopsy confirmed a case of osteoma. Below is a discussion on diagnosis & management of frontal osteomaPulse Vol.9 January-December 2016 p.45-48
