Observation of a unique case of metastatic basal cell carcinoma found by radiographic evaluation in a patient with oculocutaneous albinism.

[oculocutaneous albinism]

Basal cell carcinoma is one of the more common cancers worldwide ; 2 .8 million are diagnosed annually in the USA . However , the rate at which it metastasizes is considered very low , between 0 .0028 and 0 .5 %. For those rare cases in which metastases occur , approximately one third metastasize to the lung . Presented is a 62 -year -old Caucasian male with oculocutaneous albinism and a history of basal cell carcinomas occurring in multiple anatomic sites , most recently at the bilateral forearm and back . Surveillance PET /CT imaging led to the discovery of no less than 30 lung nodules which were consistent with basal cell carcinoma on biopsy . Histological features were remarkably similar in both the primary tumor and in the metastases . An unusual case of a non-head and neck primary basal cell carcinoma metastatic to the lung was discovered on surveillance PET /CT imaging , in a patient with oculocutaneous albinism .
