Granular cell myoblastoma of the bronchus is rare. Two patients are described, bringing the total reported to 44. Review of the literature shows that cough, chest pain, hemoptysis, and wheezing are frequent presenting symptoms and that distal atelectasis and recurrent or persistent pneumonitis are common roentgenographic findings. Though the histogenesis of this tumor remains controversial, most pathologists now believe that the cells have a neurogenic origin. Adequate open surgical resection is the treatment of choice.

A 61-year-old male Caucasian smoker patient underwent chest radiography and CT scan for persistent non-inflammatory cough, which showed a left bronchial unresectable mass. Bronchoscopy showed an endobronchial mass; washing cytology was negative and histology findings suggested diagnosis of granular cell tumor (GCT), also called Abrikossoff's tumor. After 3 weeks a new washing cytology test revealed the presence of small cell lung cancer (SCLC). A CT-scan and chest radiography showed a 30% increase in the maximum diameter of the lesion, clinically defining the primary neoplasm as malignant. The patient was referred to our institution and started chemotherapy with cisplatin and etoposide. After 6 cycles of treatment, the CT scan showed complete, disappearance of the neoplasm and bronchoscopy examination showed no endobronchial lesion, defining the mucosal surface as normal. We have reviewed and summarized the international literature with regard to bronchial localization of malignant granular cell tumor and its association with SCLC, therefore concluding that our case is the first malignant endobronchial GCT linked to SCLC.

Granular cell tumor (GCT) is an uncommon tumor of Schwann cell origin. GCT occurs in various sites throughout the body, but mediastinal GCT is very rare. We present an extremely rare case of GCT of the neck and superior mediastinum. A 36-year-old man with a 3-month history of cough was investigated at our hospital. CT and MRI revealed a spindle-shaped mass in the left neck and superior mediastinum, with features suggesting a neurogenic tumor. The tumor was successfully excised via combined neck incision and video-assisted thoracoscopic surgery. Histopathological examination showed proliferation of polygonal and spindled cells with eosinophilic granule-rich cytoplasm. These cells were S-100 protein positive, and the cytoplasmic granules were periodic acid-Schiff positive. Based on these histopathological and immunohistochemical findings, a diagnosis of GCT was established. The patient developed hoarseness immediately after the operation, and laryngoscopy revealed the left vocal cord palsy in the paramedian position, which resolved after about 3 months. The tumor did not recur during the following 10 months.

Granular cell tumor (GCT) is a slow-growing benign neoplasm that can be found in any organ. Pediatric laryngotracheal GCT is rare. We experienced a 6-year-old boy suffering from a barking cough and symptoms of stridor and croup for one month. Head and neck computed tomography revealed a protruding mass that occluded 60% of the airway lumen. Under the impression of hemangioma or papilloma, excision revealed a submucosal non-encapsulated mass. Histologically, the mass was composed of sheets of large polyhedralshaped tumor cells containing plump eosinophilic granular cytoplasm and centrally placed, small, bland-appearing nuclei. The tumor cells were positive for S-100 protein, and voluminous eosinophilic cytoplasm was stained by diastase-resistant periodic acid-Schiff. The present report describes a unique case of a huge pediatric laryngeal GCT extending to the subglottic trachea. We also review the clinical course of pediatric laryngotracheal GCT and emphasize the importance of diagnosing GCT in children.
