Persistent atelectasis and recurrent pneumonia in the same location should raise suspicion of congenital anomalies or obstructing lesions of the bronchus leading to the affected area. We present an 8-year-old black female with a history of recurrent fever, cough, atelectasis of the right middle and lower lobes, and weight loss for several months. Flexible bronchoscopy revealed a polypoid mass o...

Granular cell tumor, a soft tissue neoplasm that originates in the nervous system, is a very unusual tumor. Granular cell tumor appears as a solitary painless lesion, which can arise at virtually any body site, but is mainly found on the skin, oral cavity, respiratory tract or digestive tract. However, an intramuscular granular cell tumor is very rare. We report on a case of a granular cell tum...

Introduction: Granular cell tumors are rare neoplasms, which can be either benign or malignant. They are often discovered as incidental findings on imaging. Case: 34-year-old smoker, with complaints of fever, chills; malaise was found to have a posterior mediastenal mass on chest imaging. EBUS guided FNA of the mediastenal mass revealed histopathologic features consistent with benign granular c...

Primitive non-neural granular-cell tumor (PNGCT) is a rare tumor of uncertain lineage. It was first described by Le Boit et al. [1] as “primitive polypoid granular cell tumor” after analysis of four cases. Since then various other names have been proposed. Lazar et al. called it “primitive non-neural granular cell tumor” [2] and Chaudhry et al. coined the term “dermal non-neural granular cell t...

Introduction: Granular cell tumors (GCTs) are rare and mostly benign soft tissue tumors. Though they have been reported in all parts of body, they are generally located in the head and neck region, especially on the tongue. Some malign forms exist, but these have been rarely reported. Granular cell tumors have a neural origin and, in immunohistochemical evaluations, they express S-100 and neuro...
