  • Abstract
  • Look Inside

 The patient, a 32-year-old man, with malignant cutaneous melanoma had upper abdominal pain during his clinical follow-up course.

 X-ray examination of gastrointestinal tract revealed multiple metastatic lesions with so-called typical “Bull's eye” sign. Endoscopic examination of the stomach confirmed multiple submucosal tumors, measuring 12 to 20 mm in diameter, with central ulcer. From some of them, bleeding was observed. Distribution of the gastric lesions were somewhat chara-cteristic, situated mainly on the anterior wall of the fundus and body. No. tumors were found on the posterior wall or in antral region.

 On the second examination of upper gastrointestinal tract four months later, marked increase in size and number of the lesions with enlargement of the central ulcer was observed. No definite central ulcers were found in the lesions of small bowel.

 Althogh gastrointestinal involvement of malignant melanoma is not uncommon and radiological findings of “Bull's eye” sign is not pathognomonic for metastatic malignant melanoma, distribution of “Bull's eye” lesions in the stomach, and also no evidence of the central ulcer in the small intestinal lesion are of interest.
