Typically, the lesions are asymptomatic, slow-growing nodules, which may be found in any sweat gland\u2013bearing area. Multiple red lacunae, glomerular vessels, hairpin vessels, flower- and leaf-like vascular patterns, a polymorphic vascular pattern, globule\/lacunae\u2013like structures, a frog egg\u2013like appearance, and comedo-like openings have been defined as characteristic dermoscopic patterns of the disease. We report a case of eccrine poroma in an unusual periungual and subungual location mimicking ingrown toenails. The dermoscopic findings of the lesions were compatible with those of eccrine poromas located in areas other than the periungual area. Recurrence was observed after the first excisional biopsy. There was no recurrence 10 months after the second surgical intervention, and near-complete regrowth of the nail plate was achieved. Eccrine poroma should be considered as a differential diagnosis in the presence of slow-growing, erythematous, painful, hemorrhagic papular lesions located in the periungual area in conjunction with a prediagnosis of ingrown toenails and malignant processes.<\/jats:p>","DOI":"10.7547\/16-127","type":"journal-article","created":{"date-parts":[[2017,12,18]],"date-time":"2017-12-18T15:04:16Z","timestamp":1513609456000},"page":"551-555","source":"Crossref","is-referenced-by-count":7,"title":["Periungual
