“…EP may result from malignant transformation of a benign eccrine poroma or occur de novo. [3][4][5] The largest series of cases studied to date demonstrated that EP most commonly involves lower extremities, trunk, and head. 6 There is a predilection for elderly patients in the fifth to eighth decades of life.…”

Eccrine porocarcinoma (EP), although rare, is widely recognized as the most common malignant sweat gland tumor. EP typically grows slowly and usually is cured by surgical excision with clear margins. An elevated mortality rate, however, is observed when regional lymph nodes are involved. We herein describe cytohistologic findings in a case of metastatic EP. An 86-year-old man with a history of EP of the left lateral ankle and squamous cell carcinoma in situ (Bowen's disease) of the penis presented with enlarged left inguinal lymph nodes. A superficial fine-needle aspiration (FNA) was performed and demonstrated a hypercellular sample with discohesive clusters and/or individual tumor cells. The tumor cells were round or oval with most of the cells showing dense, refractile cytoplasm. Intracytoplasmic vacuoles were readily appreciated in some of the cells. Nuclear enlargement, high N/C ratio, nuclear hyperchromasia, bi- and multinucleation, and prominent nucleoli were seen. A diagnosis of metastatic eccrine porocarcinoma was rendered. Enlarged retroperitoneal lymph nodes were detected and CT-guided left retroperitoneal core biopsy was performed 1 week later. The biopsy revealed features consistent with metastatic eccrine porocarcinoma.

“…The lesions are most commonly found on the lower extremities, followed by the head, scalp, upper extremities, trunk and abdomen (1,(5)(6)(7)(8)(9)(10)(11)(12)(13). This malignancy most commonly affects elderly patients with an average age of 67 at the time of diagnosis, but may occur at any age (1-13).…”

“…Eccrine porocarcinoma may appear as a nodule, verrucous cauliflower-like infiltrative plaque or as a polypoid lesion that is frequently ulcerated and may bleed (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). Multinodularity, rapid growth and ulceration may be associated with either local recurrence or metastasis (1,13).…”

Eccrine porocarcinoma is a rare malignant sweat gland tumour. Clinical presentation can vary from an indurated plaque to a polypoid ulcerated and bleeding lesion. Diagnosis of eccrine porocarcinoma on clinical observation only is quite impossible. Here we present the case of a 64-year-old female patient with a small reddish nodule of the knee that, on histological evaluation, proved to be an eccrine porocarcinoma.

“…The ducts are located in the dermis and epidermis. The straight intradermal portion of the duct is the syrinx, and the coiled intradermal portion opening onto the skin surface is the acrosyringium (9,10). Tumours of the syrinx are termed syringomas and tumours of the acrosyringium are poromas.…”
