Background: Malignant granular cell tumors (GCT) are the rarest of all sarcomas, and the histologic differentiation from their benign counterpart may be extremely difficult or impossible unless metastatic disease is demonstrated. To our knowledge, this is the first report of a malignant GCT diagnosed by fine needle aspiration (FNA) cytology Granular cell tumors (GCTs) are rare lesions in the breast of putative schwannian origin. These tumors are found in multiple sites throughout the body and have a characteristic histologic appearance. Recognition of these usually benign tumors is important since clinically, radiologically, and grossl Most reports on the cytologic features of granular cell tumors have been on lesions from the breast or respiratory tract. However, there are only a few reports on fine needle aspiration (FNA) cytologic diagnosis of cutaneous or soft tissue granular cell tumors

Cytologic findings in granular cell tumors, with emphasis

Background: Granular cell tumors (GCT) formerly known as Abrikossoff tumor or granular cell myoblastoma, are rare neoplasms encountered in the fine needle aspiration (FNA) service. Named because of their highly granular cytoplasm which is invariably positive for the S-100 antibody, the classic GCT is thought to be of neural origin Granular cell tumors (GCTs) are rare. Based on histochemical reactivity for S-100 protein and ultrastructural characteristics, GCT histogenesis favors a Schwann cell origin and is characterized by large cells with a highly granular cytoplasm [ 1 - 3 ]. GCT has been reported in many locations, especially the head and neck [ 2 ]

Granular cell tumors (GCTs) are uncommon neoplasms with recently postulated origin from Schwann cell or neural crest.

INTRODUCTION. A granular cell tumor (GCT) is an uncommon tumor with an incidence of 0.017-0.029% in general surgical specimen.[1-4] It was first described in 1926 as granular cell myoblastoma by Abrikossoff.[4-8] Though the most common site of involvement is the tongue, it can occur anywhere in the body.[3-5,9] A GCT usually presents as a small solitary painless firm nodule affecting the. Granular cell tumor is a rare tumor of the soft tissue and this is characterized by proliferation of large cells with granular appearing eosinophilic cytoplasm. We report the imprint cytologic features of a case of granular cell tumor in the left calf of a 52-year-old woman. Microscopic examination showed moderate cellularity Gingival granular cell tumor of newborns is an extremely rare variant and manifests as a polypoid swelling situated exclusively over the lateral alveolar ridge, especially of the maxilla. More than 90% of patients are girls. [ 21] These lesions are likely to be reactive rather than neoplastic in nature, and, ultimately, they may be segregated.

Granular cell tumors (GCTs) have a characteristic cytological appearance, and fine-needle aspiration cytology (FNAC) has been suggested to be the diagnostic modality of choice. However, the differential diagnosis has not yet been well described. We herein describe a rare case of GCT of the breast and discuss the differential diagnosis.

In addition to Melan A, balloon cell melanomas may stain for S-100 and neuron-specific enolase.(1,11) Rhabdomyomas, oncocytomas and granular cell tumors have a similar cytologic appearance with eosinophilic granular material in the cytoplasm, comparable to what is seen in a subset of cells in this case The finely granular cytoplasm observed in some hibernomas may simulate a benign granular cell tumor. 34-36 The lack of a mature lipomatous component as well as the absence of both typical multivacuolated brown fat-like cells and a delicate vasculature help to distinguish granular cell tumors from hibernomas This report is concerned with the fine-needle aspiration (FNA) diagnosis of the granulosa cell tumor in the latter site and corroboration of the interpretation by immunocytochemistry.

DISCUSSION: Granular cell tumor is a mesenchymal tumor, probably of Schwann cell origin, with tumor cells showing abundant eosinophilic granular cytoplasm. (1) The first report of granular cell tumor is attributed to Abrikossoff in 1926 localized in the tongue and he proposed origin from striated muscle cells and he termed this lesion as. Abstract. Granular cell tumor rarely occurs in the thyroid. This case report describes the cytologic features of a granular cell tumor seen in a fine needle aspirate obtained from a 27-year-old woman with a gradually enlarging thyroid nodule. The aspirate showed single as well as syncytial clusters of cells with abundant granular cytoplasm We report a case of granular‐cell tumor (GCT) in the esophagus. This is a rare location for this tumor and only 80 cases have been described. The tumor was diagnosed in a 24‐yr‐old woman with epigastralgia. Endoscopic examination revealed a submucosal ulcerated lesion. The smears derived from esophageal brushings contained clusters of granular cells recognize the cytologic features of granular cell tumor (GCT) of the breast in a cytology specimen; distinguish characteristics of GCT from other entities in the breast; formulate a differential diagnosis for benign and malignant lesions with granular and oncocytic features in breast cytology

Granular cell tumor (GCT) also known as Abrikossoff's tumor is an uncommon soft tissue tumor of neurogenic origin. GCT of the breast accounts for < 0.1% of breast tumors and 6% of all reported cases of granular cell tumor. Although GCT is a benign tumor, malignant GCT can be seen in 1% v of the cases. GCT of the breast is diagnostically challenging as it can imitate carcinoma clinically and. Exfoliative Cytology of a Case of Bronchial Granular Cell Myoblastoma.

The histogenesis of this tumor is obscure; many theories have been proposed Higher grade tumors can be poorly or well-granulated and nuclear criteria of malignancy (nuclear atypia, binucleation, large nuclei, mitotic figures) are more reliable than granularity for determining the grade of mast cell tumors on cytology. Tumor grading for dermal (not subcutaneous) mast cell tumors in dogs is best done by histopathology Granular cell tumors are rare soft tissue tumors; they are almost never malignant, but can mimic a carcinoma. Differential diagnosis of Granular cell tumors is challenging in particular during follow up in a breast cancer patient. A misdiagnosis due to the fear of local or distant recurrence can be responsible for patient's overtreatment Granular cell tumors (GrCTs) are rare benign lesions of Schwannian origin composed of cells with abundant granular cytoplasm. GrCT was initially descried as myoblastoma in 1926 and thought to be originated from smooth muscle origin.
