“…SFT and FH can show similar storiform areas, but in FH this pattern is more prevalent. On the other hand SFT have more sclerotic areas than the FH (Kurihara et al , 1999). FH usually is negative for CD34, whereas SFT is frequently positive.…”

“…Although CD34 is commonly positive in SFTs, it is not exclusive for this tumour. Other neoplasias such as leukaemia, vascular neoplasms, hemangiopericytoma, nerve sheath tumours, smooth muscle neoplasms and dermatofibrosarcoma protuberans may be positive as well (Kurihara et al , 1999). Our cases were also strongly positive for vimentin, CD34 and bcl‐2 as in most cases summarized in Table 2.…”

“…Since its first description by Stout and Murray (1942) as a `localized pleural mesothelioma', solitary fibrous tumour (SFT) has been recognized as an uncommon benign or malignant tumour, according to the criteria proposed by Chan (1997). It has been diagnosed not only in the pleura, but also in the lung, mediastinum, peritoneum, spinal cord, soft tissue, sinonasal tract, nasopharynx, thyroid, salivary gland and orbit (Kurihara et al, 1999). In the oral cavity, to our knowledge, there are only 14 published cases in the literature (Suster et al, 1995; Fornelli et al, 1996; Brunnemann et al, 1997; Piatelli et al, 1998; Eversole et al, 1999; Iwai et al, 1999; Kurihara et al, 1999; Perez‐Ordonez et al, 1999; Lukinmaa et al, 2000).…”

In this report, we describe two more cases, emphasizing that SFT should be considered in the differential diagnosis of spindle cells tumours of the oral cavity.…”

Solitary fibrous tumour of the mouth: report of two cases involving the tongue and cheek

et al. 2002

We describe two additional cases of solitary fibrous tumour (SFT) affecting the mouth. SFT is very uncommon in the oral cavity and we found only 14 cases reported in the literature. Our two cases were well circumscribed, slow growing tumours that, after surgical removal, did not recur. Case 1 was a 3 cm nodule on the right cheek. Hypo and hypercellular adjacent areas were mainly patternless, and the stroma was formed by thin collagen fibrils. Case 2 was a 4.8 cm mass in the anterior portion of the tongue. Microscopically it was formed by spindle cells embedded in a vascularized sclerotic collagen matrix. Some areas were hypercellular with scarce collagen fibrils. The immunohistochemical findings were similar in both cases, with strong immunoreactivity for vimentin, CD34, bcl-2, focal positivity for Ki-67 and negativity for other immunomarkers. Based on these clinical, microscopical and immunohistochemical features the final diagnosis of these two cases was SFT. Diagnosis of SFT is difficult and, although uncommon, it should be considered in the differential diagnosis of oral soft tissue tumours.

“…This fact supports the theory that SFT is of fibroblastic cell origin and is not specific to the serosa. As for the oral region, only eight cases have been described in the English‐language literature 5,14–17 . The clinicopathological features of these oral SFT cases are summarized in Table 1.…”

Solitary fibrous tumor (SFT) is a rare, benign, soft tissue tumor that most commonly occurs in the pleura; however, it has recently been described in other sites of the body. To date, eight examples of oral SFT have been reported. This paper is a description of the first case of an SFT occurring as a soft tissue tumor in the mental region. Histologically, the tumor was composed predominantly of rather uniform spindle-shaped fibroblastic cells arranged in vague fascicles or in a haphazard fashion, intermingled with abundant collagen fibers. Immunohistochemically, the tumor cells were positive for CD34 and vimentin, and weakly positive for muscle actin and alpha-smooth muscle actin. The diagnosis of SFT may be difficult as this tumor shares a number of histological features with other soft tissue tumors. Awareness of its occurrence in the oral cavity is important so that confusion with other spindle cell neoplasms can be avoided.

Solitary fibrous tumors (SFT) are rare, mostly fibroblastic tumors usually situated in the pleura. Extrapleural manifestations have been described. However, the oral cavity is an uncommon localisation of this tumor. We report the very unusual case of an SFT affecting the tongue that could be removed completely because of its clear delineation. Intraoperative incisional biopsies were used to exclude malignancy. For definitive classification of the tumor, additional histopathologic examinations had to be carried out. Because SFT exhibit malignant behavior only in exceptional cases and their recurrence after complete removal has never been encountered, surgery can focus on the preservation of undisturbed function of the tongue.
