The palms of one Brazilian have led to the discovery of a more serious underlying health problem: lung cancer.
According to a case report published this week in the New England Journal of Medicine, whose authors are Denis Miyashiro and oseose A. Sanchez of the USSP, a 73-year-old woman, visited a local dermatology clinic with complaints of itching and painful abdominal lesions. palms on both hands.
The symptoms first appeared nine months earlier. While doctors carefully examined her palms, they noticed particularly sharp lines in the natural folds of her hands, plus extra curved lines and a "velvety appearance" on both hands.
In the medical sense, the woman had a rare condition, sometimes called palmoplantar keratoderma or palm acanthosis nigricans.
Unfortunately, palm appearance is almost always associated with certain types of cancer, usually a gastric or pulmonary form. In addition, the woman smoked the equivalent of one box a day for 30 years and also dealt with constant coughing and weight loss. Surprisingly, a CT scan revealed that he had lung cancer.
This is a rare condition even in people with cancer. And it's still not clear why this happens, although some researchers believe that the cancer may somehow stimulate the overproduction of skin cells in the palm.
Although it can disappear if a person is treated for cancer, it does not happen in this case. Neither treatment with fat seemed to help. Despite chemotherapy and radiotherapy, the woman's cancer continued to progress to a six-month mark on her treatment. At the time of publication, the authors wrote that she had begun another treatment but did not provide any further updates on her condition.
