Abstract
Nasal chondromesenchymal hamartoma (NCMH) is a very rare, benign sinonasal tract tumor commonly affecting infants. In this paper, in addition to presenting a systematic review of the literature on NCMH, we also report an unusual case of NCMH in an adolescent patient. A systematic review conducted following the PRISMA guidelines. PubMed, EMBASE and manual search through references of relevant publication were utilised to gather all published case-reports of NCMH. Data collected from each case-report for patient demographics, site and size of NCMH, clinical presentation, co-morbidities, diagnostic methods, treatment options and follow-up methods. The systemic review collected sixty-two case-reports of NCMH (including our case) affecting 42 men and 21 women (2:1 male to female ratio). Mean average age was 5.1 years (age range: 1 day to 70 years). The anatomical sites of the tumor were: nasal cavity (n = 17), paranasal sinuses (n = 30), orbital region (n = 17), and the base of the skull (n = 16). The reported clinical manifestations were nasal obstruction or congestion (n = 29), nasal mass (n = 27), epistaxis (n = 6), orbital symptoms (n = 14). NCMH is a very rare cause of nasal masses in infants and toddlers. Our case and previous case reports confirm that NCMH can mimic other benign and malignant tumors, therefore we should be vigilant for rare pathologies that lead to nasal masses. Recently the link between DIECR1 mutation with NCMH has been established, so NCMH should be considered in any patient with nasal or orbital symptoms with a history of DICER1-related tumor spectrum.
