Akantozis nigrikans ile birlikte gastrik adenokarsinom ve nörofibromatozis

We presented a case of acanthosis nigricans who exhibited an internal malignancy and neurofibrornatosis. The patient who is 45 years old had pruritus and axillary and inguinal discoloration resembling Acanthosis nigricans. The diagnosis was confirmed by the biopsy of the skin. The tomographic, endoscopie, and histopathologic singular revealed a poorly differentiated gastric carcinoma of the corpus which was at advanced stage. There were macules in close similarity with café au lait macules, and skin-colored, pedinculated soft nodules. The histopathologic diagnosis of neuroflbrorna was confirmed by the excision of one of the nodules.
