Cutaneous granular cell tumor: case report

Background: Granular cell tumor (Abrikossoff’s tumor) is a rare and slow-growing tumor of the soft tissue. Originated from the Schwann cells, it is often a benign tumor, but it can be malignant in 1-3% of the cases. Malignant cases can cause significant morbidity and mortality. It may develop in many anatomic locations, especially in the head and neck region, and also in skin and subcutaneous t...

The Lipid Composition of Hibernoma as Compared with That of Lipoma and of Mouse Brown Fat.

is the morphologic similarity between the tumor and this type of fat : like brown fat, hibernoma is composed, wholly or largely, of multivacuolated fat cells; and both are highly vascular (1). In this study the lipid composition of 2 hibernomas has been compared with that of ordinary lipomas and of mouse brown fat. 1\1ATERIAIS AND METHODS Two patients were operated on for a soft tissue tumor in...

A Twenty-Four-Year-Old Woman with Left Flank Lipoma-Like Hibernoma

A 24-year-old woman presented with a 5-month history of a left flank mass that was painful on palpation. Magnetic resonance imaging revealed a 10.0 × 6.0 × 2.5 cm mass consistent with lipoma. A fatty lobulated mass was excised and subjected to H&E staining and immunohistochemical analyses. The specimen consisted of mature univacuolated adipocytic cells, with intermixed multivacuolated eosinophi...

Prenatal Diagnosis of Granular Cell Tumor

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...
