Fine needle aspiration cytology of solitary fibrous tumor of the orbit

Abstract

Solitary fibrous tumor (SFT) is a distinct and a rare spindle cell neoplasm, commonly known to occur in the pleura and other serosal sites. With the advent of immunohistochemistry, varied extraserosal sites are being recognized as common locations for this rare tumor. We report a case of SFT in a 50-year-old male patient who presented with multiple swellings in the eyelid, with emphasis on the cytological features.

Perigastric solitary fibrous tumor (SFT) diagnosed on fine needle aspiration: A case report and review of literature

“…In our review of literature, most of the case series and case reports in the literature were retrospective cytologic examination of cases diagnosed as SFTs on biopsies or surgical resections. 4,[8][9][10][11][12][13][14][15][16][17] As expected, most of these cases arose from the pleura and extremities. 8,[11][12][13][14][15] The cytologic features of SFT include scant to moderately cellular smears composed of singly scattered to clusters of monotonous population of spindle to oval shaped cells with fine chromatin pattern and scant cytoplasm.…”

“…10 Table 1 summarizes the tumor location, cytomorphologic features and immunohistochemical stain results of cytology case reports, and case series of SFTs. 4,[8][9][10][11][12][13][14][15][16][17] According In the past, CD34, BCL2, and CD99 were some of the stains used to diagnose SFT. However, they are not specific to SFT.…”

Solitary fibrous tumor of the tongue: Cytopathologic fine needle aspiration findings

“…We read with great interest the article by Krishnamurthy on solitary fibrous tumor (SFT) of the orbit. [1] We fully agree that SFT represents a significant diagnostic challenge for the cytopathologists. Although SFT may arise at any site,[2] only 17 cases of tongue SFT have been reported so far[3] and a review of the literature failed to reveal cytology-based reports of this entity.…”

Metastatic leiomyosarcoma to the pancreas diagnosed on endoscopic ultrasound‐guided fine needle aspiration – A report of two cases with review of spindle cell lesions of pancreas

“…The most frequent features of SFT described in literature include stripped nuclei and ropy bands of collagen, which should prompt a differential diagnosis of SFT on cytology smears . Moreover, immunolabelling with cluster of differentiation (CD)34, CD99, B‐cell lymphoma‐2 (bcl‐2) and signal transducer and activator of transcription 6 STAT‐6 helps in supplementing the morphology.…”
