Xanthoma disseminatum (XD) is a rare, benign non-familial mucocutaneous disorder, which is a subset of non-Langerhans cell histiocytosis. It is characterized by mucocutaneous xanthomas in a disseminated form typically involving the eyelids, trunk, face, and proximal extremities and occurs in flexures and folds such as axillae and the groin. Mucosal involvement of the respiratory or gastrointest...

Juvenile xanthogranuloma (JXG xanthogranulomas (JXGs) are asymptomatic; benign; self papules and nodules composed of histiocytic cells. Most common site of occurrence is skin of the head and neck region and trunk but occurrence at rare sites iris of the eye, anterior abdominal wall and tibia had been reported in literature. common form of non–Langerhans cell histiocytosis. Approximately 35% of ...

Juvenile xanthogranuloma (JXG) is a benign, self-healing, non-Langerhans cell histiocytosis characterized by accumulation of lipid-laden macrophages. It occurs most commonly on the head and neck of infants and young children and resolves spontaneously without treatment [1]. Lesions may be single or multiple, congenital or acquired. Size varies from few millimetres to several centimetres. Two ma...

calcifying odontogenic cyst (coc), central odontogenic fibroma (cof) and aggressive central giant cell granuloma (cgcg) are rare pathologic diseases affecting the jaws. while the co-existence of two of them is reported in the literature, existence of all three conditions in one patient is an extremely rare entity. in the present report, initial biopsy revealed fibrosarcoma, therefore mandibular...

Giant cell tumor (GCT) is a benign primary bone neoplasm that usually occurre in the long bones. The skull is affected in only 1% of cases, predominantly in the sphenoid and temporal bones. Maxillary sinus involvement is exceedingly rare. The case is a 26 year-old man presented with history of gradually increasing swelling in the right side of face without any history of trauma or systemic diso...

A 60-year-old Taiwanese woman was referred in August 1999 for evaluation of multiple papules. Two months earlier, she first noted a reddish papule on her left buttock. In the subsequent 2 months, multiple similar lesions developed on her back, abdomen, chest and face. The patient had a history of hypertension for 9 years, diabetes mellitus for 8 years and atrial fibrillation for 3 years, and ha...

central giant cell granuloma (cgcg), formerly called giant cell reparative granuloma, is a non-neoplastic proliferative lesion of unknown etiology. it occurs most commonly in the mandible. the case reported here resembled a wide variety of conditions that led to a misdiagnosis both on clinical and radiographic examinations but was histopathologically diagnosed as cgcg. we describe a case of cgc...

Background:  Giant cell tumor of tendon sheath (GCTTS) is often thought of as a volar finger mass. We hypothesized that GCTTS are equally common on the dorsal and volar aspects of the hand. In addition, we hypothesized that there are no factors associated with the location (volar versus dorsal) and largest measured dimension of a GCTTS.  Methods:  A total of 126 patients with a pathological dia...

Objective: The purpose of this study was to retrospectively analyze the demographic characteristics of patients with central peripheral giant cell granulomas (CGCGs) / (PGCGs) an Iranian population. Methods: In this 38-year retrospective study, the data were obtained from records of 1019 patients with CGCG and PGCG of the jaws referred to the Department of Oral and Maxillofacial, Pathology, ...
