Short-Spindled Cell Haemangioblastoma with CD34 Expression: New Histopathological Variant or Just a Stochastic Cytological Singularity?

Figure 2

Light Microscopy Morphophenotype. (a) Spindle cells in the first resection sample. (b) Second resection sample: spindle cell component seen with haematoxylin and eosin (upper field) and with reticular fibers stain (lower field). The reticulin pattern is absent in the latter. (c) Third resection sample: transition area between fusiform stromal cells (left field) and conventional stromal cells (right field and lower inset). (d) Panoramic view of spindle cells in the third resection sample. A multinucleated giant cell can also be recognised (dotted-lined square). (e) High magnification photomicrograph of a syncytium-like cell. (f) Glomeruloid or yarn ball cluster of short-spindled cells “gomitoli.”
