Abstract PDF: An eccrine squamous syringometaplasia (ESS) is defined as a mature squamous metaplasia of the eccrine ducts. The clinical and pathological features of an ESS are presented. Syringometaplasia is a rare lesion, mostly occuring in the extremities, and as far as we know, no report on the ESS has been published in Korean literature. We experienced a case of an ESS occured in a 15 year-old male, who had a tender erythematous plaque in the right knee. The histologic examination revealed some scattered nests of metaplastic squamous epithelium in the deep dermis, associated with acute nonspecific panniculitis. The importance of the ESS is that it histologically simulates the well differentiated squamous cell carcinoma. The histopathologic findings were discussed and a brief review of the literature was made.
