A case of a 68-year-old male is presented, with a history of asymptoma
tic slight scaling, infiltrated patches with an atrophic central porti
on, of 3 months of evolution on the face and trunk, A chest X-ray show
ed an oat cell lung carcinoma, with the same evolution time as the cut
aneous lesions. Several cutaneous biopsies showed typical sarcoid gran
ulomas, with profuse giant cells. An immunohistochemical study showed
B-cell-positive granulomas. The patient was treated with cytostatic dr
ugs and prednisone, leading to cutaneous, radiological and clinical co
mplete regression of the lesions. We think that this case corresponds
to a tumor-related cutaneous sarcoid granuloma reaction.
