“…This entity is also known as benign triton tumor or neuromuscular choristoma. [14][15][16][17] Whether cutaneous SNH is related to these other entities or not is not apparent at this point. However, the lack of other elements may be an indication that this is a unique form of hamartoma.…”

Cutaneous hamartomas are tumor-like proliferations of tissue indigenous to the organ but arranged abnormally. There are examples in the literature of cutaneous hamartomas composed of a variety of different components. To our knowledge, there is no previous report of such cutaneous solitary neural hamartoma. Our case occurred in a 51-year-old man with pain and paresthesia in the right shoulder associated with a nodule that was surgically removed. There was no history of trauma, other skin nodules, neurofibromatosis, or tuberous sclerosis. Histologically, there was an unencapsulated nodule, composed of mature nerve bundles noted abnormally high within the papillary dermis, extending to the reticular dermis with periadnexal distribution. Immunohistochemically, the nerve bundles were positive for S-100, including the smaller nerve twigs, and the perineurium was highlighted by epithelial membrane antigen, reminiscent of normal peripheral nerves. Although, neural components including mature nerve bundles have been described in various cutaneous hamartomas, this represents a peculiar case of a cutaneous mature peripheral nerve hamartoma. Whether this is related to other entities of cutaneous hamartomas (ie, neurofollicular hamartoma, folliculosebaceous cystic hamartoma) is not yet apparent, although it is probably a unique entity.

“…A total of 15 articles were included in this analysis reporting 18 cases. [1][2][3][4][5]8,12,[20][21][22]27,30,31,36,42 These patients with NMC presented mostly in early childhood (before the age of 2 in 10 of 18 cases), with only 4 patients presenting in adulthood; the mean age of presentation was 9.75 years (range birth to 68 years). Both sexes were affected, with 11 cases involving female patients and 7 involving male patients being reported.…”
