Granular cell tumors are an uncommon soft tissue neoplasm. Malignant granular cell tumors comprise <2% of all granular cell tumors, are associated with aggressive behavior and poor clinical outcome, and are poorly understood in terms of tumor etiology and systematic treatment. Because of its rarity, the genetic basis of malignant granular cell tumor remains unknown. We performed whole-genome se...
BACKGROUND The congenital granular cell tumour of the newborn, also known as congenital epulis or Neumann's tumor, is rare. It occurs on the gingiva of the anterior alveolar ridge of the jaws. This lesion behaves in a benign manner and no recurrent or metastatic lesions have been reported. CASE REPORT We are reporting a 2-day-old female neonate, who came to our unit with a well defined, solit...
We report on a case of extraluminal tracheal granular-cell tumor which was interpreted as a Hurthle-cell neoplasm of the thyroid on fine-needle aspirate. Review of the literature reveals only one other such case. The patient was a 35-yr-old female who presented with an enlarged thyroid. Aspiration cytology revealed a syncytium of cells with abundant granular cytoplasm interpreted as a thyroid f...
A full-term Caucasian girl with Apgar scores of 9/10 at 1 and 5 minutes and a birth weight of 3,500 g was born to a healthy 24-year-old mother following her second normal pregnancy. Physical examination after birth revealed a firm, broad-based, pedunculated, pinkishred tumor that measured 25 × 10 × 10 mm and was inserted into the maxillary alveolus to the left of the midline (Fig. 1). The infan...
BACKGROUND Granular cell tumors are rare neoplasms which can occur in any part of the body. Granular cell tumors of the orbit account for only 3 % of all granular cell tumor cases. Computed tomography and magnetic resonance imaging of the orbit have proven useful for diagnosing orbital tumors. However, the rarity of intraorbital granular cell tumors poses a significant diagnostic challenge for ...
Granular cell tumor is a rare tumor of unknown etiology that more commonly affects the oral cavity but can also occur at other sites. The majorities of granular cell tumors are benign and present as a singular dermal nodule. We discuss a case of granular cell tumor of the fourth toe in a 54-year-old patient that was treated with conservative surgery, instead of amputation, and reconstruction wi...
most popular sources for electromagnetic waves. however, there are many concerns regarding their biological effects on the body, especially the central nervous system. therefore, the aim of this study was to evaluate the effects of cell phone radiation on histology of the cerebellar granular cells in the neonatal rat. materials and methods: we selected some wistar rats. then, we randomly divide...
Granular-cell tumor is an uncommon cause of breast mass in premenopausal women that presents as a painless chronic lump. It mimics infiltrating carcinoma clinically and radiologically. Granular-cell tumor is usually benign, and the treatment is wide local excision. Definitive pre-operative diagnosis helps to avoid unnecessary mastectomy. We present clinical, mamographic, and sonographic charact...
