ABSTRACT
This is a case of primary hyperparathyroidism in a female teenager with multiple fractures and severe bone manifestations. The histopathology revealed atypical parathyroid adenoma, an exceedingly rare form of hyperparathyroidism; its main differential diagnosis is parathyroid carcinoma, as it shares both clinical and histological characteristics with it, in addition to its still uncertain malignant potential.

We describe the case of a 61-year-old man from the Dominican Republic admitted with diarrhoea, fevers and weight loss who was found to have lab studies and imaging (including radiolabeled somatostatin positron emission tomography/CT scan) initially consistent with a metastatic neuroendocrine tumour. However, after weeks of workup and multiple inconclusive biopsies, he was diagnosed with disseminated extrapulmonary tuberculosis. Here we examine the data for neuroendocrine tumour and tuberculosis labs and imaging to delineate where these studies overlap. We also analyse the biases and pitfalls in this case that led to a protracted diagnosis.
