Matrix-producing carcinoma (MPC) is extremely rare. Limited reports have described the cytological aspects of MPC. Herein, we present 2 cases of MPC, both of which showed ring-enhancement on magnetic resonance imaging (MRI) and chondromyxoid matrix on cytological specimens. In these cases, the diagnosis of MPC was preoperatively suspected. Recognizing extracellular matrix as chondromyxoid matri...

Juvenile ossifying fibroma (JOF) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. Two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (TrJOF) and a psammomatoid juvenile ossifying fibroma (PJOF). Psammomatoid variant is predominantly a craniofac...

BACKGROUND Giant cell fibroma (GCF) is a distinct type of fibroma with characteristic large, stellate mononuclear or multinucleated giant fibroblasts; the stroma of GCF is relatively unexplored. The Picrosirus red polarizing microscopy technique is used to characterize the collagen fibers. The aim of this study was to evaluate the staining properties of collagen fibers in GCF and to correlate i...

Desmoplastic fibroma is a rare benign primary bone tumor that is histologically similar to the soft tissue desmoid tumor. It most often involves the mandible, large long bone or iliac bone. Desmoplastic fibroma in a toe has been extremely rarely reported. Authors report a rare case of desmoplastic fibroma of bone occurring in the distal phalanx of a foot, with descriptions of the radiographic a...

Localized gingival growths are one of the maximum regularly encountered lesions within oral cavity, which taken into consideration to be reactive as opposed neoplastic. Those encompass pyogenic granuloma, inflammation fibroma, peripheral large cellular and ossifying fibroma (POF). Among those lesions, Peripheral Ossifying Fibroma (POF) is an occasionally happening non-neoplastic growth with reg...

Aim: Ovarian fibroma, fibrothecoma and thecoma are benign neoplasia of the ovary. The aim this study is to analyze clinical characteristics, histopathological results surgical management ovarian fibroma/fibrothecoma.Materials Methods: This a retrospective 51 cases who underwent treatment because adnexial mass. reported as fibroma/fibrothecomas were analyzed.Results: mean age patients 58.7 years...

Epiphyseal tumours in young patients are a diagnostic challenge, largely due to their rarity. The differential diagnosis for a lytic lesion with well-defined margins at the epiphysis of a long bone in a young patient should fundamentally include three lesions typically found at the epiphysis: chondroblastoma, giant-cell tumour of bone and clear cell chondrosarcoma. Other conditions to consider ...

Objectives: Fibro-osseous lesions of the craniofacial complex comprise of a diverse, interesting and challenging group of conditions that pose difficulties in classification and treatment. The two most confused benign fibro-osseous lesions are fibrous dysplasia and ossifying fibroma. Sometimes, the classic clinical, radiologic or pathologic features of fibrous dysplasia or ossifying fibroma may...
