Incidental Diagnosis of Mantle Lymphoma Made by Sigmoidoscopy

چکیده
A 82-year-old man has been followed in our oncology hospital after prostatic cancer and prostatectomy. He was medicated with gonadotropin releasing hormone superagonist goserelin and olmesartan for arterial hypertension. Due to the recent installation of orthopnea, a chest X-ray was carried out, revealing a mass in the right hilar region which was subsequently characterized as right hilar and mediastinal lymphadenopathy by chest CT. Bronchoscopy with bronchial biopsies, citology and microbiological studies revealed no signs of malignancy or infection. Taking into consideration the patient’s medical history and the occasional back pain he referred, PET scan was thought to be the appropriate following exam. In addition to confirming hypermetabolism in the already known lymphadenopathies, PET-CT scan also showed a hypermetabolic focus at the rectosigmoid junction (Fig. 1). Sigmoidoscopy was performed and revealed two subepithelial lesions at 10 and 18 cm from the anal verge (Fig. 2). Biopsy specimens were obtained by using a ‘‘biopsy-onbiopsy’’ technique. Histological examination showed the presence of a lymphoid neoplasia of small sized cells with irregular nuclei, fine chromatin, small inconspicuous
