Histology of endocrine mucin–producing sweat gland carcinoma
In EMPSGC, sections show a dermally based tumour mass under an intact epidermis. It consisted predominantly of nodules of the tumour as well as cystic spaces somewhat reminiscent of a hydrocystoma (figures 1, 2, 3). Higher power reveals a uniform population of round-to-oval cells with fairly abundant pale and pink cytoplasm. The nuclei have fine stippled chromatin consistent with neuroendocrine differentiation (figure 4). Areas transitioning into mucinous carcinoma, with tumour islands floating in copious mucinous material may be seen (figure 5).
