Pheochromocytoma cells (phaeochromocytoma) are a tumor that forms in the adrenal medulla and consists of chromocyte-like cells. They have a dark gray or black color, which is due to the melanin pigment they contain.
Pheochromocytic tumor cells can be either benign or malignant. Benign tumors usually do not cause symptoms and can be removed with surgery. Malignant tumors can cause a variety of symptoms, including abdominal pain, nausea, vomiting, weight loss, and others.
Treatment of pheochromocytic tumors can be surgical, radiation, or a combination. Surgical treatment involves removing the tumor and part of the adrenal gland. Radiation treatment may be used to shrink the tumor and reduce its activity. Combination treatment includes surgical removal of the tumor and subsequent radiation therapy.
Overall, pheochromocytic tumor is a rare disease that can cause serious symptoms. Treatment should be prescribed by a doctor based on the individual characteristics of the patient.
