We report a unique case of a 4-year-old girl with an intriguing fibrohistiocytic tumour. Magnetic resonance imaging scans showed a dural mass of variegated intensity compressing the left occipital pole and apparently extending toward the superior sagittal sinus. Grossly, the cut surface of the surgical specimen was yellow, pale, and soft with reddish kernel-like crusts. Histologically, the yellow areas resembled cholesterol granulomas with widespread coagulative necrosis, cholesterol clefts, powdery calcification, foreign body-type giant cells, and foamy macrophages, while the scattered red spots contained numerous multinucleated giant cells of foreign-body and Touton types, the former with amphophilic to slightly eosinophilic cytoplasm. Immunoperoxidase reactions confirmed the expression of histiocytic markers and vimentin. As far as we know, no tumour displaying these peculiar morphological features has yet been described.

We report a 50-year-old woman with no relevant clinical history who presented with headache and loss of memory. Magnetic resonance imaging showed a left parieto-temporal mass with annular enhancement after contrast media administration, rendering a radiological diagnosis of high-grade astrocytic neoplasm. Tumour sampling was performed but the patient ultimately died as a result of disease. Microscopically, the lesion had areas of glioblastoma mixed with a benign mesenchymal constituent; the former showed hypercellularity, endothelial proliferation, high mitotic activity and necrosis, while the latter showed fascicles of long spindle cells surrounded by collagen and reticulin fibers. With approximately 40 previously reported cases, gliofibroma is a rare neoplasm defined as either glio-desmoplastic or glial/benign mesenchymal. As shown in our case, its prognosis is apparently determined by the degree of anaplasia of the glial component.

A metaplastic papillary tumor of the Fallopian tube is an extremely uncommon condition, with odd and confusing features that make it difficult to categorize as benign or borderline. Here, we summarize all the published cases to date and document the case of a 41-year-old woman diagnosed with this alteration after her last childbirth and ensuing tubal ligation. One of the tubes was bulky and filled with a caramel-like substance encircling a blurry spot. Light microscopy detailed a slender stalk covered by eosinophilic, columnar plump cells, showing atypical nuclei and focal budding. Mitotic figures were absent. The immunohistochemistry panel was positive for pan-cytokeratin, epithelial membrane antigen, cyclin D1, and hormone receptors. Additionally, a proliferation index of less than 5% was rated using Ki-67. The true nature of this tumor (reactive vs neoplastic) is uncertain. Nonetheless, its association with pregnancy suggests an adaptive change, likely similar to the atypical transdifferentiation proposed for Arias-Stella reaction.
