Immunotherapy in combination with chemotherapy for Peutz-Jeghers syndrome with advanced cervical cancer: A case report

Figure 1 Transoral single-balloon enterosocpy results and cervical cancer histopathological results. A: The images show a polypoid tissue measuring 2 cm × 3 cm was identified 1.5 m below the flexural ligament and was biopsied; B: The pathology of the polyp showed a dendritic extension of the mucosal muscle layer into the central part of the polyp, with the glands forming a villi-like structure. The surface of the polyp was covered with normal epithelium and the interstitium showed no obvious inflammatory lesions; C: Pathological findings of cervical cancer revealed a highly differentiated adenocarcinoma of the cervix, partly with microscopic adenocarcinomatous changes, infiltrating into the deep mesenchymal layer near the outer membrane, with visible vascular tumour plugs and metastases or infiltrations in the right external iliac lymph nodes.
