Fig. 1 (A) Preoperative photograph showing the semi-transparent bulla, sized approximately 2.5×3 cm, with a whitish nodule inside, located on the right upper back of the patient. (B) Appearance inside the bulla: a firm central tissue core, within a serous fluid-filled sac.
Fig. 2 (A) Scanning view (1:1) demonstrating the whole architecture of the tumor with cystic change (H&E). Microscopic finding shows multiple dilated lymphatics above the typical nests of shadow cells and basophilic cells. (B) Arrow indicates ghost cells, which are keratinized basaloid cells, with a red-colored anucleated appearance (H&E, ×200). (C) On D2-40 immunohistochemical staining, the endothelial lining cells of dilated lymphatic channels show immunopositivity (×600).
