Neurofibromatosis type 1 (NF-1), also known as Von- Recklinghausen disease, is a rare autosomal dominant genetic condition, resulting from mutation of the NF1 gene (located at chromosome 17q11.2). It is characterized by multiple dermatological manifestations such as café au lait macules, axillary and inguinal freckling and tumoral growth along cutaneous nerves, called neurofibromas .
Plexiform neurofibroma is a relatively uncommon variant of neurofibroma, which presents as deformed bulging masses arising from the nerves and involves connective tissue and skin folds (lesion described as a bag of worms). Although these are generally benign, a significant potential for malignant transformation is present, which is seen in 5-10% of larger tumors [3,4]. Owing to the infiltrating nature of these tumors, a complete resection is seldom possible.
We report a case of a 30 year old male who presented with a chronic history of progressively growing mass in his right axilla. Multiple smaller sized neurofibromas were appreciated all over the body including face, trunk and legs ranging from 0.7cm to 4.3cm in widest diameter, which also showed a positive buttonhole sign. Additionally, multiple café au lait macules (more than 6 in number, each greater than 15mm in size) were seen on various parts of the body (Figure 1), providing clinical diagnosis for Neurofibromatosis Type 1 according to National Institutes of Health Consensus Development Conference. Histopathological evaluation confirmed the diagnosis of plexiform neurofibroma (Figure 2).The patient was advised surgical intervention for symptomatic relief. He was counselled regarding its benefits, probable complications and chances of recurrence in this case. The patient however, denied surgery for the time being, post which he was lost to follow up.
