Abstract
We report a 71-year-old man with syringomatous carcinoma (SC) on the dorsal aspect of right hand. He noticed an asymptomatic papule for five years before his first visit of our hospital. And then, tumor size gradually increased and became dark-purplish erythematous, painful, ulcerated, hard plaque of 4×8cm in size. Although the clinical appearance resembled to squamous cell carcinoma, histopathological findings of tubules possessing comma-like extensions discerned it as SC. While the most frequent site of SC is face and head in western countries, it is at hand in Japan.
