“…Based on this hypothesis, a clear mechanism for the development of the neurofibroma on our patient's fingertip is evident. This case seems to confirm the premise that the superficial form of plexiform neurofibroma, involving small nerves in the dermis or subcutis, is not necessarily pathognomic for von Recklinghausen's disease, as previously reported 10,11 .…”

“…In our case, the tumor presented on the right 4th finger tip as a small rubbery nodule that was located superficially on the dermis. It involved a small superficial nerve, and was similar to recently described cases in which an isolated plexiform neurofibroma occurred as a superficial form involving small nerves in the dermis 10,11 . The patient had no personal or family history of other abnormalities suggestive of NF, but had been treated for myasthenia gravis since 1989.…”

“…Moreover, several cases of isolated plexiform neurofibroma have recently been observed in otherwise healthy patients with no family history of NF or other anomalies, suggesting that the presence of a plexiform neurofibroma does not always indicate associated NF or structural anomalies [9][10][11] . In our case, the tumor presented on the right 4th finger tip as a small rubbery nodule that was located superficially on the dermis.…”

We report a case of an isolated plexiform neurofibroma occurring in a patient with myasthenia gravis. A 48-year-old man presented with asymptomatic skin-colored nodules on the tip of his 4th finger. Microscopically, a plexiform neurofibroma was identified located in the dermis that appeared to originate from small superficial nerves. He had a 20-year history of treated myasthenia gravis; otherwise, his personal and family histories were unremarkable. Given that myasthenia gravis is a disorder of the peripheral nerves, plexiform neurofibromas could be associated with myasthenia gravis. However, the development of an isolated plexiform neurofibroma in a case of myasthenia gravis has not yet been reported. The occurrence of a neurofibromas in a patient with myasthenia gravis suggests a link in the pathogenesis of these two diseases. (Ann Dermatol (Seoul) 21(1) 53∼55, 2009)

Sigmoid colon plexiform neurofibroma as a colonic subepithelial mass: a case report

Plexiform neurofibroma (PN) is an uncommon benign tumor, usually associated with neurofibromatosis type 1. As most PNs involve the craniomaxillofacial region, PN of the colon is very rare. Here we present a case of PN involving the sigmoid colon. A 43-year-old male patient presented to the outpatient clinic for the evaluation of an incidentally discovered sigmoid colon mass. A colonoscopic biopsy was performed for the mass, and the result revealed neuronal proliferation. The patient visited the outpatient clinic a year later with symptoms of abdominal pain and stool caliber change. Biopsy was repeated for the sigmoid colon mass, and the results showed mucosal Schwann cell proliferation and S-100 immunostaining positivity. Computed tomography and magnetic resonance imaging were performed for further evaluation, and neurofibroma or schwannoma was suspected based on the imaging studies. For an accurate diagnosis, the patient underwent surgery to remove the sigmoid colon mass. The final diagnosis of the mass was confirmed as PN. We hereby report a rare case of PN involving the sigmoid colon that could not be diagnosed before surgery.
