Nuclear protein in testis (NUT) midline carcinoma (NMC) is a poorly differentiated squamous cell carcinoma that is characterized by a balanced translocation between chromosomes 15 and 19 [t(15;19)(q14;p13.1)]. This genetic aberration results in the fusion of the NUT gene on chromosome 15 to the bromodomain containing 4 (BRD4) gene on chromosome 19. The resultant BRD4-NUT fusion oncogene leads to global hypoacetylation and transcriptional repression of genes required for differentiation." Although it was first reported in 1991 by Kubonishi et al., awareness of this condition remains low and the diagnosis is overlooked initially in a number of patients. A 36-year-old man complained of cough and right-sided chest pain for 3 weeks before presentation. Imaging studies revealed a right hilar mass, and a bronchoscopic biopsy was consistent with an aggressive poorly differentiated neoplasm. A combination of cisplatin, ifosfamide, and etoposide was administered for two cycles without any improvement. A repeat core biopsy showed focal squamous differentiation; and given the clinical presentation along with the histologic features, NMC was considered in the differential diagnosis. Immunohistochemical staining for NUT was positive, and dual-color break-apart fluorescence in situ hybridization demonstrated BRD4-NUT rearrangement, thereby confirming a diagnosis of NMC. Our patient was subsequently enrolled on a phase 1 clinical trial of a novel, orally bioavailable bromodomain and extra terminal inhibitor, GSK525762 (NCT01587703). This report illustrates the challenges in diagnosing this rare malignancy, and highlights new treatment options for these patients.

NUT carcinoma (NC) is an aggressive squamous tumor characterized by NUT gene rearrangement, and the most common fusion form is BRD4-NUT. However, NC diagnosis is difficult for its rareness and often being confused with a variety of poorly differentiated tumors. A 21-year-old Chinese woman was referred to our hospital for cough and intermittent fever. Chest computed tomography (CT) imaging revealed a left lobe hilar mass. Fiberoptic bronchoscopy results showed that tumor cells were poorly differentiated. In combination with immunohistochemistry staining, she was misdiagnosed with Ewing's sarcoma/primitive neuroectodermal tumor. Next-generation sequencing (NGS) revealing BRD4-NUT fusion, and NUT immunohistochemistry confirmed the diagnosis of NC. Subsequently, left pneumonectomy and lymph node dissection were performed, and the patient received pemetrexed and lobaplatin treatment. NGS technology played an important role in NC diagnosis in this case, and it may have clinical use for rare cancer diagnosis and guidance of potential targeted therapies.
