Case Report Acanthosis Nigricans Associated with an Adrenocortical Tumor in a Pediatric Patient

Malignant acanthosis nigricans (AN) is a rare paraneoplastic syndrome seen primarily in adults with an underlying diagnosis of gastrointestinal adenocarcinoma. Malignant AN is characterized by hyperpigmentation and velvety hyperplasia of the epidermis. This condition is generally not associated with tumors in pediatric populations or in the adrenal gland. We present a case of malignant AN in a pediatric patient with a nonmalignant, functional adrenocortical tumor

Three Uncommon Tumors Mimicking More Common Tumors Affecting Vision

The practice of neuro-ophthalmology overlaps frequently with neuro-oncology. Meningioma, pituitary macroadenomas, and other primary and common metastatic tumors are often in our differential. We present three cases where the initial impression of a more common tumor, was ultimately determined to be a rare mimic with additional implications for the care of the patient
