INTRODUCTION A granular cell tumor involving the breast parenchyma was first described by Abrikossoff in 1931. Localization of this lesion to the breast is very rare, accounting for between 5% and 15% of all granular cell tumor cases. We present this case because of the rarity of this tumor. It is frequently confused with breast carcinoma on clinical and radiological examination, and its diagno...

A case of granular cell tumor of the breast in a 43-year-old woman is described. The patient presented with a painless mass in the upper-outer quadrant of her right breast. Mammography showed a spiculated tumor and ultrasonography demonstrated a hypoechoic mass with an irregular border. Magnetic resonance (MR) mammography revealed a homogeneous enhanced mass in T1-weighted images using Gd-DTPA ...

Six to eight percent of granular cell tumors are seen in the breast. Although mostly benign, they rarely have malignant features clinically and radiologically reminding of breast cancer. This may lead to a potential misdiagnosis of breast carcinoma and overtreatment of patients. The final diagnosis is made by immunohistochemical examination. We performed excisional biopsy on a patient who was d...

Granular cell tumor is a type of benign tumor that rarely shows malignant findings. It can occur in any part of the body, it is most commonly seen in the tongue. The breast is an extraordinary localization site for granular cell tumor. When it forms a solitary mass with irregular contours in the breast, it can mimic a clinically and radiologically malignant breast tumor, which may lead to unnec...

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...

Objective. Granular cell tumors arise from neurogenic mesenchymal stem cells and can occur anywhere throughout the body. They rarely present as breast masses and should be included in the differential diagnosis of pediatric breast neoplasms. We report a rare presentation of a pediatric breast granular cell tumor and a review of the literature. Participant. A 15-year-old female presented with an...

Granular cell tumors (granular cell rnyoblastoma) are neoplasms Which pursue a benign clinical course in large majority of cases. Tongue is the classic location for this tumor, however, rarely it is seen ill many other sites. Cases of granular cell tumor have been described in both male and female breasts The recognition of this entity in breast is important because it mimics breast carcinoma c...

Granular cell tumor is a rare benign non-encapsulated tumor that mostly presents in oral cavity. Breast localization is uncommon and occurs in about one per 1000 cases of breast cancers. It mainly affects premenopausal women showing the possible role of estrogen and progesterone levels in the progression of this tumor. Granular cell tumor is a great emulator of the invasive ductal carcinoma of ...

A case of granular cell tumor of the breast in a 36-year-old woman is reported. The patient presented with a hard mass,1.5 cm in diameter in the upper-outer quadrant of the left breast. Physical examination and ultrasonography suggested the presence of breast carcinoma. An aspiration biopsy cytology(ABC)specimen wasevaluated as class II, and dynamic magnetic resonance(MR)mammography indicated a...

A 22-year-old female patient presented with a breast mass lesion with a clinical suspicion of a fibroadenoma. Histological evaluation revealed a rare benign neoplasm - granular cell tumor.Granular cell tumor is rare neoplasm that may arise in virtually any body site, and in 5% it occurs in the breast. The histogenesis of this tumor is still rather controversial and currently the most acceptable...
