Fig. 1.

Exemplary macroscopic visualization of different lesion presentations in AE patients: [a] (patient A9) and [b] (patient A37) both show lesions from AE patients that had a radical (curative) resection reported by the surgeons, but who maintained a recEm18-seropositivity until the end of the present study period. [c] (patient D3) shows part of the resected material that was, according to the surgeons, radically resected from an immunocompromised AE patient, but who nevertheless maintained a recEm18-seropositivity until the end of the study period. [d] (patient F2) shows CT-findings of two small lesions that were considered as putatively “abortive”; the patient remained stable for a period of 7 years (= until the end of the study period). [e & f] (patient F4) shows histological analyses of the resected “abortive” material, HE-staining for [e], and PAS-staining for [f], where fragments of the PAS-positive laminated layer can still be seen.
