Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell c...
BACKGROUND Giant cell fibroma is a type of fibrous tumour of the oral mucosa which rarely affects children under the age of 10. The purpose of this paper was to contribute two clinically and histologically documented cases of giant cell fibroma in the free gingiva of a 7 and 6 year old boys. METHODS Both nodules were presented in the mandibular anterior region. In the differential diagnosis s...
Introduction: Despite similar histopathological features, peripheral giant cell granuloma (PGCG) and central giant cell granuloma (CGCG) differ in their biological behavior. PGCG and CGCG are hemorrhagic/vascular lesions, clinically and microscopically. Angiogenesis is necessary for the growth and development of lesions and affects their clinical behavior. CD105 is a useful vascular marker for...
Background: Tuberous sclerosis (TSC) is inherited as an autosomal dominant disease, characterized by skin lesion and tubers in vital organs, especially brain in three categories including subependymal nodules, cortical tubers and subependymal giant cell astrocytoma. Subependymal giant cell astrocytoma (SEGA) is an indolent neoplasm which usually arises at the cauda tha...
BACKGROUND Malignant transformation of giant cell tumors of bones, that is, secondary malignant giant cell tumor of bone, is rare. The most common symptoms are local pain and swelling. There are no prior reports of giant cell tumor of bone with fever of unknown origin at the onset. Here we present a case of a secondary malignant giant cell tumor of bone due to malignant transformation 40 years ...

BACKGROUND Multinucleated giant cell-containing tumors and pseudotumors of bone represent a heterogeneous group of benign and malignant lesions. Differential diagnosis can be challenging, particularly in instances of limited sampling. The purpose of this study was to evaluate the contribution of the P63 in the positive and differential diagnosis of giant cell tumor of bone. METHODS This study...
Osteoclast-like giant cell tumor of the pancreas is a rare non-endocrine neoplasm composed of reactive multinucleated giant cells admixed with mononuclear stromal cells. We report a case of osteoclast-like giant cell tumor of the pancreas in a 58-year-old female with vague clinical symptoms. Endoscopic ultrasound-guided aspirate from the mass revealed numerous characteristic osteoclast-like gia...
BACKGROUND Tuberous sclerosis complex is an autosomal dominant disorder predisposing to the development of benign lesions in different body organs, mainly in the brain, kidney, liver, skin, heart, and lung. Subependymal giant cell astrocytomas are characteristic brain tumors that occur in 10% to 20% of tuberous sclerosis complex patients and are almost exclusively related to tuberous sclerosis ...
This short report discusses a case of neurofibroma containing floret-like multinucleated giant cells. This being the second such case in the literature. Floret-like multinucleated giant cells have been reported in gynaecomastia and neurofibroma in neurofibromatosis type 1. These cells have been reported in uncommon soft tissue tumours including pleomorphic lipoma, giant cell collagenoma, giant ...
