“…Follow‐up data indicate a benign outcome with no evidence of recurrence during intervals ranging from 3 months to 7 years (Table 1). 2–12,15 Histopathological features of papillary glioneuronal tumor are similar in all reported cases, invariably reproducing the first description of this tumor by Komori 2…”

“…Typical morphological features are pseudopapillary structures composed of frequently thickened hyalinized blood vessels lined by uniform small astrocytes and a proliferation of neurocytic cells eventually admixed with ganglioid and ganglion cells. Rabdoid, minigemistocytic, and Olig2 (a recently established oligodendroglial marker) positive cells have been recognized too 1–16 …”

Papillary glioneuronal tumor is a recently identified low-grade brain neoplasm classified as variant of ganglioglioma. Its salient morphological characteristics are the presence of pseudopapillary structures composed of blood vessels, often hyalinized, lined by uniform small astrocytes and a proliferation of neurocytic cells, eventually admixed with ganglioid and ganglion cells. We present a case of papillary glioneuronal tumor occurring in a 15-year-old female with an unusual hemorrhagic onset. The clinical, morphological and immunohistochemical features are discussed and the published literature is reviewed. This article proposes that papillary glioneuronal tumor should be included in the differential diagnosis of patients with tumoral related brain hemorrhage.

“…PGNT was first described by Komori et al in 1998 in a series of 9 cases 3 . After that, about 33 cases were reported in succession in the English language literature 5–30 . In 2007, WHO classified PGNT as a Grade I neuronal‐glial tumor because of the characteristic papillary architecture and bipartite (astrocytic and neuronal/neurocytic) cell populations.…”

Multiple vascular patterns are presented in tumors of the central nervous system (CNS), including microvascular hyperplasia, branching capillaries, numerous capillaries without definite pattern, hyalinized vessels, and angiomatous area. These vascular patterns play important roles in pathological diagnosis of brain tumors. Because of insufficient recognition of the significance of the various vascular patterns, only a few of them have been applied in pathological diagnosis, leading to missed diagnosis and diagnostic errors. Microvascular hyperplasia can present in multiple brain tumors but display different diagnostic values. Otherwise, varied brain tumors characterized by branching capillaries or vascular pattern mimicking branching capillaries should be given careful consideration. Therefore, a familiarity of these tumors and their vascular pattern is essential for general pathologists. This study reviews the value of various kinds of vascular patterns for pathological diagnosis of brain tumors, constructs a framework for better understanding, and provides a novel perspective for general pathologists.
