A solitary fibrous tumour (SFT) is an unusual spindle cell neoplasm. It frequently arises from the serosal surface of pleural cavity but has recently been described in diverse extrapleural sites. Urogenital localization is rare and only 36 cases of SFTs of the kidney have been described on published report.  We report a case of a large SFT clinically and radiologically thought to be renal cell carcinoma arising in the kidney of a 30- year-old female. The radical nephrectomy was performed. The tumour was a well- circumscribed, solid mass attached to the renal pelvis without necrosis and haemorrhage. Histopathologically, a spindle cell neoplasia with alternating hypo and hypercellular areas, storiform, fascicular and hemangipericytoma- like growth pattern and less cellular dense collagen deposits were observed. Immunohistochemical studies revealed reactivity for CD34, CD99 and Bcl-2 protein.

Fibrous Tumor

Solitary Fibrous Tumors (SFT) are rare spindle cell neoplasm that typically originate from the pleura. However, cases of the SFT are described with origin in other organs, including the urinary and genital apparatus. Within the kidney, except from the renal pelvis, only 19 cases of SFT are described and such rarity of localization makes the histogenesis and the prognosis of the tumor rather unknown. We report the case of a 72-year-old lady who attended our Unit for a mass that was clinically palpable at the level of the left hemiabdomen. The tomodensitographic test indicated a 19cm-diameter mass of likely pertinence of the middle bystender of the left kidney. She had undergone left radical nephrectomy. The histological examination highlighted a solitary fibrous tumor (SFT): the presence of hypercellularity, of cellular pleiomorphism and of a high number of mitosis has led to a histological diagnosis of malignancy for the neoplasm analyzed. The SFT are of rare clinical comparison: this does not allow for a deep knowledge of the lesion histogenesis and prognosis; moreover, the clinical behavior should be more precisely defined.

Solitary fibrous tumor is a spindle cell neoplasm mostly originating from pleura; however, it has also recently been reported to be extrapleural. A 57-year-old man presented with left lumbal pain. Ultrasonography and computed tomography showed a cystic lesion of 14 × 11 cm with solid areas and septations in middle and lower poles of the left kidney. Radical nephrectomy was performed. Immunohistochemical studies showed strong reactions with CD34 and CD99. A nuclear positivity with Ki-67 was observed in less than 1% of cells. Despite repeated stainings with vimentin, no clear tumor evaluation could be made due to artifacts. The tumor was negative with Bcl-2, desmin, HMB-45, S100, FVIII, and CD31. Histopathological and molecular studies made the diagnosis of a solitary fibrous tumor. The patient is now currently free of disease at the 26th month of followup.

Solitary fibrous tumour (SFT), previously denominated as haemangiopericytoma, is a rare, spindle cell neoplasm that was first described in the thoracic pleura. It is now known that this tumour may develop from almost any anatomic location. We report a case of SFT, in a 65-year-old man, which was located in the muscularis propria layer of the caecum with involvement of the serosa and the ileocecal appendix, location never described in the literature, and with an uncommon clinical presentation of hematochezia. A radical right hemicolectomy was performed, and the patient was asymptomatic without evidence of metastasis or relapse after 6 months of follow-up.

Solitary fibrous tumour (SFT) is a rare spindle cell neoplasm that usually arises from serosal surfaces. Although it is now increasingly recognized in extra-serosal locations, only two previous cases of SFT arising in an extremity have been reported. We describe another such case and review the literature regarding extra-serosal SFT.

Abstract A 4-year-old female captive-bred snake of the genus Bothrops showed swelling on the left side of the oral cavity, suggesting the development of neoplasia. The mass was removed surgically and sent for pathological examination. Two months later a new increase in volume in the same site was observed, suggesting recurrence. The lesion was completely removed and sent for pathological analysis. Histologically, the two-samples consisted of a mass with highly-cell density composed of spindle-shaped anaplastic cells arranged in interwoven bundles, distributed throughout the tissue extension and, occasionally, polygonal cells arranged in irregular fascicles. The Masson trichrome staining showed modest amount of collagen supporting the neoplastic cells. PAS-positive content was not observed in the cytoplasm of neoplastic cells. Histological and histochemical findings indicated that it was a spindle cell neoplasm, but the classification was not possible. Immunohistochemistry was requested and performed using the streptavidin-biotin-peroxidase method. The markers used were anti-vimentin, anti-PCNA, anti-EMA, anti-melan A and anti-melanosome, anti-desmin, anti-actin, anti-CD68 and anti- S100protein. The neoplastic cells were immunoreactive for vimentin and PCNA and negative for the other antibodies. The morphology characterization, histochemical and immunohistochemical analysis of neoplastic cells allowed the definitive diagnosis of oral fibrosarcoma.

We report a case of myopericytoma of the neck. A 23-year-old woman noticed a small, nontender mass in her left supraclavicular fossa. The mass had grown over a period of 5 months, prompting her to seek evaluation. On examination, no motor or sensory deficits were present. Imaging suggested that a mass had originated in the middle scalene muscle. Computed-tomography–guided core needle biopsy demonstrated a spindle-cell neoplasm with smooth-muscle differentiation. Complete surgical excision was performed. Histopathologic and immunohistochemical evaluations of the tissue sample suggested a myopericytoma. Myopericytoma is an extremely rare tumor of the head and neck. To the best of our knowledge, this is the first reported case of a myopericytoma originating in a scalene muscle.
