We treated a case of adenocarcinoma which was suggested to possibly have an apocrine origin. It occurred in the right axilla of an 83-year-old man as an erythematous nodule. A histological examination revealed adenocarcinoma composed of atypical cells with abundant eosinophilic cytoplasm and finding of decapitation in some parts of the tumor. The tumor cells were PAS (+) (with resistance to diastase), CEA (-), EMA (+), secretory-component (+), GCDFP-15 (+), BRST-3 (+). No abnormal laboratory data and no evidence of metastasis to other organs were observed. We excised the lesion and regional lymph nodes en bloc and metastatic cells were detected in the lymph nodes. According to our review of the literature, about 30% of such cases do have metastasis to the regional lymph nodes. Based on these findings, we believe that a broad excision and radical lymph node dissection are necessary in the treatment of this disease.
