ABSTRACT
Immunoglobulin G4 (IgG4‑related diseases) affects various tissues and organs of the human body. Orbital, adnexal, and scleral inflammations were already reported in the medical literature. To the best of our knowledge, we report the first case of intraocular IgG4‑associated inflammatory mass in the ciliary body mimicking as a melanoma in a 23‑year‑old female from Northeast India. Characteristic histopathology, immunohistochemistry in the tissue, protein chemistry, and raised serum IgG4 were supportive for the diagnosis. As this newly diagnosed disease has multi‑organ affection and little is known about its pathogenesis particularly in eye and adnexa, the present case will open many challenges in clinico‑pathological diagnosis and research in the future.
ABSTRACT
Malignant granular cell tumor (MGCT) is rare tumors that comprise 1-2% of all granular cell tumors. They commonly arise on lower extremity, nuchal region, chest wall, gastrointestinal tract, head, and neck but very rarely in breast. We report a case of a MGCT of breast with review of literature. The patient had noticed a breast mass 4 years back which was operated, and wide local excision was done. The tumor was diagnosed as MGCT. The tumor fulfi lled 3 of the 6 criteria of Fanburg-Smith et al. The patient received 8 cycles of chemotherapy thereafter with 4 cycles of antharacycline and 4 of taxanes. However, the tumor reoccurred 4 years after resection and grew rapidly. Contrast-enhanced computed tomography done showed a large lobulated breast mass with axillary lymph node metastasis. She underwent Modifi ed Radical Mastectomy with axillary clearance. The histopathology this time also revealed similar malignant tumor. To the best of our knowledge, only 7 cases have been reported in indexed English literature occurring primarily in breast.
