Peripheral ameloblastoma (PA) is a rare extraosseous odontogenic tumor with histological characteristics similar to those of the common intraosseous ameloblastoma. Two questions regarding PA remain: its histogenic origin and how to differentiate between PA and intraoral basal cell carcinoma. We describe a patient with PA. The result of immunohistochemistry showed cytokeratin (CK) 7-, CK14+, CK1...
INTRODUCTION Six cases are reported, each presented at the 11th Biennial Congress of the International Association of Oral Pathologists as an instructive case for differential diagnosis on the basis of clinical, imaging or histological features. CLINICAL PICTURE Case diagnoses included a large, possibly intraosseous, myofibroma presenting with an oral mass; Langerhans cell histiocytosis with ...
Lipoma is a very common tumor developed in soft tissue like subepithelium, however, intraosseous lipoma developed inside the bone is a quite rare tumor showing less prevalence than 0.1% or 2.5% among primary tumors developed inside the bones. Intraosseous lipoma has been reported to occur usually in metaphyseal or epiphyseal regions of long bones such as femur, tibia, fibula, and calcaneus, but...
Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare carcinoma, which arises within the jaws without connection to the oral mucosa and presumably develops from a remnant of odontogenic epithelium. We present a case of solid type PIOSCC in a 52-year-old male patient complaining of dull pain on his left lower molar. In this case, early stage PIOSCC mimicking a periapical lesion might l...
