Granular cell tumors (GCT) are rare tumors of Schwann cell origin which were more often found in subcutaneous locations than in relation to major nerves. We describe a GCT that occurred within the hypoglossal nerve located in the left submandibular area of a 32-year-old man who initially presented with a muscular atrophy and deviation of the tongue. We also review the literature related to the ...

The association of hematological malignancies with a mediastinal germ cell tumor (GCT) is very rare. We report one case of a young adult male with primary mediastinal GCT who subsequently developed acute megakaryoblastic leukemia involving isochromosome (12p). A 25-yr-old man had been diagnosed with a mediastinal GCT and underwent surgical resection and adjuvant chemotherapy. At 1 week after th...

Giant cell tumour (GCT) of bone is a benign aggressive tumour of the bone. It typically presents in persons aged 20 - 40 years. It is rare in adolescents and children. In most cases, GCT of bone occurs in the metaphyseal and epiphyseal regions of long bones. However, in children with open physes, GCT of bone may be centered in the metaphysis and may abut the physis. GCT is most commonly found i...

Granular cell tumor (GCT) is a rare benign neoplasm of the skin that accounts for 0.5% of all soft-tissue tumors. The tumor mostly presents with a symptomatic slowly growing solitary nodule and overlying normal skin; therefore, it is not always considered in the differential diagnosis. Here, we report a 58-year-old female patient who presented with a 4-year history of a slowly growing mass, wit...

W e read with great interest the article by Goldberg et al. (1), in which the authors sought to further characterize the metabolic phenotype of the population of pregnant women with the positive glucose challenge test (GCT) test in relation to the time of day when the test was done. They found that women who had GCT done in the afternoon have a better metabolic function and a lower risk of subs...

This concise review summarises tissue and serum markers useful for differential diagnosis of germ cell tumours (GCT), with focus on the most common testicular GCT (TGCT). GCT are characterised by phenotypic heterogeneity due to largely retained embryonic pluripotency and aberrant somatic differentiation. TGCT that occur in young men are divided into two main types, seminoma and nonseminoma, bot...

Disturbances in granulosa cell apoptosis have been implicated in the pathogenesis of human granulosa cell tumors (GCTs). Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a potent cytokine that induces apoptosis in a variety of malignancies without toxic effects on benign cells. The aim of this study was to investigate the expression and functionality of the TRAIL receptors DR4...

Secondary transformation in Germ Cell Tumours (GCT) is an extremely rare event. We report here a case of malignant melanoma arising in primary mediastinal GCT. A young male presented with new onset dyspnoea and a mediastinal mass. As serum alpha fetoprotein was raised, a diagnosis of primary mediastinal GCT was made. He achieved remission with standard chemotherapy and resection of the mass. Af...

Giant cell tumor (GCT) of the spine is a rare benign tumor, but can be aggressive and can exhibit a high local recurrence rate. Furthermore, GCT of the upper thoracic spine may pose diagnostic and management difficulties. Here, we report a rare case of GCT of the upper thoracic spine with soft tissue extension to the spinal canal. The patient was managed by decompressive laminectomy and postero...

Congenital granular cell tumor (GCT) is a relatively rare intraoral benign tumor, approximately 200 cases of which have been reported in the neonatal period worldwide. The newborn infant may have feeding problems and respiratory difficulties due to airway obstruction. This lesion may be diagnosed by prenatal ultrasonography and simple resection is mostly required. We report a case of an adult t...
