<unk>  (LCLC-RP) is a rare histological form of lung cancer, currently classified as a variant of<unk>  cell lung carcinoma (LCLC). In order for a LCLC to be subclassified as the<unk><unk>  variant, at least 10% of the malignant tumor cells must contain distinctive structures composed of tangled intermediate filaments that displace the cell nucleus outward toward the cell membrane. The whorled eosinophilic inclusions in LCLC-RP cells give it a microscopic resemblance to malignant cells found in rhabdomyosarcoma (RMS), a rare neoplasm arising from transformed skeletal muscle. Despite their microscopic similarities, LCLC-RP is not associated with rhabdomyosarcoma. Although<unk>  variants of LCLC are sometimes referred to as<unk>  carcinomas", this particular term should be reserved for examples of "pure"<unk>  neoplasms (i.e. those that do not contain cells containing other histological variants)
