I have recently been diagnosed with a small basal cell carcinoma on my scalp. It has been suggested that I consider either radiation or mohs. I have a brother who last year had what at first looked like basal cell in a similar spot...on closer study it turmed out to be something quite rare...the oncologist had not had experience of it before and the literature has only one or two examples....a neuroendocrine tumor usually found in internal organs, intestines, lungs. By the time it would be seen on the skin it would be expected to be quite advanced and well spread. It however has shown no other manifestations. A year later he is still clear. My dermatologist received this news with little interest...as many physicians do when patients seem to have found something strange online. I can t say she was dismissive but her familiarity with basal cells is considerable I am sure, and mine, like my brother s, presents unspectacularly. If the neuroendocrine tumor presenting on the scalp with no other manifestations is extremely rare, the chances of two among siblings seems like successive lottery tickets both winning jackpots...though rather in reverse as regards luck, no? No one seems to know if there is a genetic proclivity, since the sample size is too small to infer. Do I insist that my dermatologist look for neuroendocrine characteristics, or will they become apparent in a mohs procedure?
