Abstract
The patient was a 73-year-old male who had noticed a rice sized nodule on his forehead one month before the first visit to our physical clinic. Following a clinical diagnosis of malignancy, he was referred to our clinic. Physical examination at the first visit showed a dome-like, elastic hard nodule, (2.5×2.3cm in size) on the scalp. He was diagnosed with acute-type ATLL based on the histopathological and molecular biological analysis. In addition, because he had recognized digestive organ symptoms such as diarrhea, and the adult T-cell leukemia/lymphoma for a month, we performed digestive tract endoscopy. The examination disclosed that there were a lot of ulcers in the colon, and irregular thickening of the gastric mucosa. On histological examination of the mucosae, these lesions showed ATLL cell infiltration. [Skin Cancer (Japan) 2007; 22: 297-302]
