Squamous differentiation in malignant eccrine poroma.

Abstract

Squamous differentiation in poral adnexal neoplasms is a rare event. Two cases are presented of malignant eccrine poroma in which areas of squamous differentiation showing the features of squamous cell carcinoma were present. The areas of squamous differentiation were found within the invasive components of the lesions and appeared to result from direct transformation of the poral epithelial cells. A review of the literature on this unusual phenomenon is presented.

Sarcomatoid eccrine porocarcinoma: report of two cases and a review of the literature.

Eccrine porocarcinoma is an uncommon sweat gland malignancy. To the best of our knowledge, there has been no report in the English literature of porocarcinoma with predominantly undifferentiated sarcomatous change. We present two cases of sarcomatoid eccrine porocarcinoma associated with a benign poroma. Case 1 pertained to an 82-year-old woman with an ulcerated chest wall tumor, and Case 2 was that of a 74-year-old woman who presented with an ulcerated plaque in the lower leg. Case 1 showed an unusual pseudo-angiosarcomatous morphology with spindle cells dissecting through collagen bundles and forming vascular like channels. Case 2 revealed high-grade malignant spindle cells with focal evidence of ductal differentiation. In both the cases, benign poromatous elements were histologically evident. Immunohistochemistry performed showed pancytokeratin positivity in spindle cells of both lesions. Epithelial membrane antigen and carcino-embryonic antigen positivity in the malignant ductal elements and focal smooth muscle actin staining of the spindle cells were demonstrated in Case 2. A brief review of relevant literature is presented.

Eccrine porocarcinoma arising from preexisting eccrine poroma of the scalp after radiotherapy for cervical cancer.

Eccrine porocarcinoma may arise from eccrine poroma or it may occur de novo. We present a rapidly growing occipital malignant eccrine poroma on the scalp following to a radiotherapy for cervical carcinoma. A wide excision with skin grafting resulted no recurrence during a 1-year followup. Although malignant transformation is well known for other skin cancers this was not reported for eccrine poroma.
