Myelolipomas are ­very ­rare ­benign ­tumours com­posed of an admix­ture of ­mature adi­pose ­tissue and ­normal hae­mat­o­poietic ­cells. Although ­they are ­most com­monly ­found in the ­adrenal ­glands, ­extra-­adrenal mye­lo­lip­omas are doc­u­mented. We ­describe a ­case of mye­lo­lipoma ­arising in the ­lung in a 52-­year-old man. The ­lesion was ­found inci­den­tally in asso­ci­a­tion ­with a car­ci­noid. To our knowl­edge, ­this is the ­second ­instance of ­this neo­plasm pre­senting as a ­lung ­lesion, and the ­first ­case asso­ciated ­with bron­chial car­ci­noid. Pathogenesis and aetio­logy of mye­lo­lip­omas are ­referred to in ­this ­paper ­with spe­cial ­regard to the clin­ical and path­o­log­ical find­ings.
