Intracranial solitary fibrous tumors are rare, and intraventricular fibrous tumors are even more unusual. We report a case of solitary fibrous tumor in the region of trigone and body of the left lateral ventricle and discuss the clinical presentation, CT characteristics, and histopathologic features with 1-year follow-up. We speculate that the tumor arose from the perivascular connective tissue...

Sir: We read with interest the recent work by McCluggage et al. reporting the diagnostic utility of CD10 expression in distinguishing endometrial stromal lesions from other potential mimics, such as uterine smooth muscle neoplasms. CD10 is a cell-surface neutral endopeptidase detected in a variety of normal and neoplastic conditions. However, to the best of our knowledge, CD10 expression has ne...

Solitary fibrous tumour (SFT) is a rare oncological entity that most often arises in the pleura. Over the past 10 years, the tumour has been described at numerous extrapleural locations. We present the case of a 42-year-old female Caucasian patient with an extrapleural SFT located at the anterior thoracic wall for 22 years, with atypical histological characteristics and clinical features of mal...

A 60-year-old male presented with dyspnea and chest pain. He was referred with massive bulky mass. A mass in the left lung was observed using chest X-ray (Figures 1).  A computed tomography scan of the chest showed a mass on the left lung with complete lung collapse Figures 2 (A, B). The needle biopsy was performed and the case was diagnosed with solitary fibro...

We report a case of pancreatic hamartoma-like solitary fibrous tumor which was differentiated from pancreatic hamartoma with the detection of NAB2-STAT6 fusion, a specific mutation for solitary fibrous tumors. A pancreatic well-demarcated solid nodule, 21 × 17 mm, of 82-year-old man was surgically enucleated. Microscopic findings were close to a pancreatic hamartoma that consisted of sparsely d...
