Introduction Nuchal fibroma or collagenosis nuchae is a rare benign tumour. It is a slow growing neoplasia of unknown etiogenesis, asymptomatic and of variegated histology. They are more common in males but our case was a female patient. The presentation may mimic sarcoma at times. Case Report An unusual case of a very large neck mass in a 62 years old female patient is reported. The growth involved the dorso-cervical region over a period of approximately 8 years but remained asymptomatic. The mass was excised and post excision histopathology was reported as nuchal fibroma. Discussion The case reported is large compared to the usual size of nuchal fibroma. Association with diabetes mellitus and Gardner’s syndrome has been reported in literature. MRI is the imaging of choice to establish the differential diagnosis.
Melanomas are malignant tumours, which originate from melanocytes. Melanocytes originate from the neural crest cells and then migrate to various tissues in the body during the course of development. Sinonasal melanoma are rare tumours and the aetiopathogenesis, treatment and staging of the tumours are still an area of debate. There remains paucity of studies dealing exclusively with sinonasal melanoma. We attempt to make a comprehensive study of the disease by reviewing the existing literature on sinonasal melanoma. METHODOLOGYReview of existing literature on the melanoma of nose and paranasal sinus. RESULTS AND DISCUSSIONThe melanoma of the sinonasal tract are rare and account for 1% of all melanoma. The aetiology of the tumour is still debated and the behaviour of the tumour remains conspicuously different both genetically and clinically from its cutaneous counterpart. Surgery remains the mainstay of treatment, though newer modalities are being explored. The prognosis of these tumours remain grim with a 5-year survival rate of about 25%. CONCLUSIONEarly diagnosis, histopathological confirmation and aggressive control of the primary tumour is the standard modality of treatment. The molecular biology and genetics of the tumour are an interesting field of research and targeted therapy may hold the key to improve the outcome in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
