Eccrine porocarcinoma arising from the knee

Abstract

Key Clinical MessageEnlarged eccrine porocarcinoma of the knee was encountered as a hemorrhagic bulky tumor. After controlling bleeding with Mohs’ paste, local excision of the lesion was the mainstay of treatment. Pathological examination revealed poroid cells, cuticle cells, and prickle cells cancer components, suggesting that malignancy must be excluded by resection.

Porocarcinoma of the left arm: A report of a rare skin cancer case and literature review

“…To date, only 15 cases occurring on the arms (including the current case) have been documented in the literature. 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 Clinically, PC presents as a slow‐growing, red, dome‐shaped skin nodule with a shiny surface or as a wart‐like plaque, papule, or polyp that is sometimes painful and ulcerative. The lesion size can range from <1 cm to up to 10 cm.…”

“…Given its rare occurrence, most of the literature has reported single clinical cases and a few case series, and there are currently no uniform international guidelines for these patients. 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31…”

“…The location on the arms represents only 4.8% of PC common sites (only 14 cases have been registered at the moment). 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 …”

“…The location on the arms represents only 4.8% of PC common sites (only 14 cases have been registered at the moment). [6][7][8][9][10][11][12][13][14][15][16] In this case report, we present a case of PC that gradually ulcerated over about 10 months on the left arm of a 93-year-old male patient with various comorbidities with a literature review on PC and its potential therapy.…”

Sentinel lymph node biopsy in porocarcinoma: A case reports

“…Clinically EPC can be presented as an erythematous or violaceous nodule, papule or plaque with an infiltrative or erosive pattern. EPC usually arises on the lower extremities (44%), followed by the trunk (24%), head & neck (23%), upper extremities (11%), and rarely involves other areas [ 3 , 5 , 11 ]. Microscopically, EPC is characterized by a cluster of anaplastic cells with nuclear hyperchromasia and important mitotic activity, extending from the epidermis to the dermis, surrounded by ductal lumen.…”
