A Rare Coexistence: Breast Cancer, Pheochromocytoma and Von Recklinghausen Disease

Breast cancer associated with type-1 neurofibromatosis is a rare clinical entity. These patients have a higher risk of developing various types of cancers, especially tumors derived from the embryogenic neural crest, such as pheochromocytoma. This publication aims to add to the literature a rare association between Type-1 Neurofibromatosis, breast cancer, and pheochromocytoma. We present a rare case of a 51-year-old Tunisian woman with neurofibromatosis who was diagnosed with breast cancer and pheochromocytoma. The breast tumor was classified as T4b N1M0, and the discovery of the pheochromocytoma was incidental to thoracic-abdominal-pelvic CT. She underwent surgery to remove the adrenal gland and was referred to medical oncologists to receive chemotherapy for her breast cancer. Type-1 Neurofibromatosis disorder is a benign disease but can expose patients to numerous neoplasms. The challenging diagnosis at an early stage can worsen the prognosis and make medical care more difficult.
