Large, atypical peripheral ossifying fibromas are known as giant peripheral ossifying fibromas.  These lesions have often been associated with heterogeneous clinical and radiographic characteristics subsequently leading to their misdiagnosis.  Biopsies have been the gold standard for the diagnosis of such lesions.  This study reports on an acute presentation of giant peripheral ossifying fibrom...

  Ependymomas accounts for about 2%–6% of CNS and 60%–70% of spinal cord tumors. Several histological patterns of these neoplasms are well known, but little attention has been devoted to a variant composed of giant cells. In spite of apparently “worrisome” histology, giant cell ependymoma seems to be a neoplasm with a relatively good prognosis. This report presents a case of giant cell ependym...

The aetiopathogenesis of epuli, a group of benign gingival hyperplasias, remains unclear. The purpose of the present study was to determine similarities and differences between benign (epulus) and malignant (cancer) gingival hyperplasias based on the evaluation of three signal pathways stimulated by the IFN-gamma complex. Five gingival specimens sampled from giant cell epulus, fibrous epulus, c...

congenital granular cell tumor (cgct) is a unique benign tumor of soft tissue in newborns, which usually occurs on the anterior alveolar mucosa of the jaws. it is 8 to 10 times more prevalent in females than males. we present a case report of a 3-month-old female infant, who had a solitary mass on the anterior mandibular alveolar ridge. the lesion, which was histologically a congenital granular...

giant uterine leiomyomas are extremely rare neoplasms and are challenging both diagnostically and therapeutically. a 49-year-old premenopausal female presented at our department complaining of abdominal pain and distention for several years. ultrasound (us), color doppler us, abdominal computed tomography imaging after administration of contrast material, and abdominal magnetic resonance imagin...

primary ureteral neoplasms are very rare and its prevalence is less than 1% of all genitourinary neoplasms. we report a symptomatic giant ureteral fibro epithelial polyp in adult women presenting as a bladder mass which was resected ureteroscopically and reported at the first time from iran. cystoscopy is growing use in the treatment of urinary tract lesions cystoscopy can be used in large lesi...

Thymic epithelial neoplasms are commonly aetiology of the anterior mediastinum masses in adults. It represents 20–30% of all mediastinal tumours in adults. Ectopic thymomas usually affect the neck, mediastinal compartments, lung, and pleura, arising from aberrant thymic tissue. For giant thymoma, there is still no consensus on the surgical approach.  We herein report a patient with a giant thym...

Peripheral giant cell granuloma (PGCG) is a common reactive gingival lesion that histologically resembles the central giant cell granuloma, and is a central lesion of the jaws. Occasionally, central giant cell granuloma-like lesions may be seen in association with hyperparathyroidism. Rarely, PGCG-like lesions have been described in a background of hyperparathyroidism. We describe the case of a...
