A 20-year-old man presented to our outpatient clinic with hemoptysis, cough, and pleuritic chest pain. His chest radiograph and pulmonary function tests (PFT) were normal. A bronchoscopy showed a small yellowish patch with a regular surface. A direct bronchoscopic biopsy was performed. The pathologic findings showed a benign granular cell tumor. The respiratory symptoms resolved after biopsying the tumor. On follow?up, there were no signs of recurrence of the granular cell tumor after a period of 24 months.

Although colorectal granular cell tumors (GCTs) are rare, their incidental finding has increased as the use of diagnostic colonoscopy has become more common. Here we describe the case of a 41-yr-old man with a GCT in the descending colon that was detected after a screening colonoscopy. Endoscopic examination revealed a yellowish submucosal tumor, 13x12 mm in diameter, in the descending colon. Endoscopic mucosal resection (EMR) followed by histological examination revealed that the tumor was composed of plump histiocyte-like cells with an abundant granular eosinophilic cytoplasm and small round nuclei. The tumor cells expressed S-100 protein and stained with periodic acid-Schiff, but were negative for desmin and cytokeratin. The resected tumor was diagnosed as a GCT. Colonoscopists should consider the possibility of GCT in the differential diagnosis of yellowish submucosal tumors of the colon. In such patients, EMR seems to be a feasible and safe approach for diagnosis and treatment.

A 53-year-old woman complaining of vertical diplopia, presented with a localized swelling in the right lower lid. Magnetic resonance imaging studies demonstrated a relatively well-defined mass in the inferior rectus with similar signal characteristics to the muscle. Excisional biopsy of the mass revealed granular cell tumor composed of S-100 positive cells with acidophilic granular cytoplasm and a peripheral lymphocytic infiltration. Granular cell tumor, which is very rare in the orbit, should be considered in the differential diagnosis of tumors adjacent to or within the extraocular muscles, particularly in the inferior orbit.

We report a very rare case of atypical granular cell tumor arising in the neurohypophysis of a 56-year-old woman. The tumor was seen on radiology to be lobulated, soft and diffusely enhanced, the same as pituitary macroadenoma, but it was anatomically localized within the posterior part of the hypophysis. We partially removed the tumor via the transsphenoidal approach. The pathology showed nuclear pleomorphism, spindling features, and lymphoplasmacytic infiltration. Ki-67 and S-100 protein were focally positive in tumor cells. Histological diagnosis confirmed an atypical granular cell tumor in the sellar region, which is a rare tumor that often has the clinical appearance of a pituitary adenoma. Ophthalmologic symptoms are the most common, followed by endocrinologic manifestations. Here we describe its symptoms and radiological and pathological features.
