Dear Editor,
Alopecia areata (AA) is a non-scarring dermatologic condition usually distinguished by patches of hair loss on the scalp. It is characteristically associated with autoimmune diseases, stress or family history of AA. The relationship with tumors of the digestive tract has been reported in two cases: gastrointestinal stromal tumor (GIST) of esophageal origin (1) and gastric adenocarcinoma (2).
Case report
We report the case of a 38-year-old man who suddenly developed patchy regions of hair loss on the scalp. He began treatment with topical corticosteroids. Two months later he complained of lower back pain with mechanical characteristics. In addition, he also complained later of abdominal pain in the lower abdomen, vomiting and jaundice, with the following analytical findings: 328 U/L, GPT 995 U/L, GGT 406 U/L, FA 469 U/L, and total bilirubin 7.12 mg/dL (direct 5.8 mg/dL). In the lumbar MRI scan, multiple bone blastic lesions suggestive of metastatic disease were observed. The abdominal CT showed a thickening of the gastric fundus and multiple lymphadenopathy retroperitoneals, in cardiophrenic angles and in the mesentery root. Endoscopy showed a subcardial lesion suggestive of malignancy and biopsy confirmed an adenocarcinoma with signet ring cells. Percutaneous cholangiography showed diffuse involvement of the biliary tree secondary to solid lesions. The patient presented clinical worsening and he died a month after diagnosis.
Discussion
Paraneoplastic cutaneous manifestations associated with gastric carcinoma include acanthosis nigricans, diffuse seborrheic keratosis and acquired pachydermatoglyphia (3).
To our knowledge, this is the second reported case of AA with gastric cancer. There are other published studies that show the association of AA with hematologic malignancies such as Hodgkin's lymphoma (4) and thymoma (5).
We believe that AA may be associated with malignant disorders, and thus this needs to be taken into account in the treatment of these patients.
