Department of Dermatology, Fundación Jiménez Díaz, Universidad Autónoma, Madrid, Spain.

Poromas are benign cutaneous adnexal neoplasms with differentiation toward excretory ducts of eccrine and apocrine glands. They are mainly composed of solid aggregates of small, monomorphous, round, and basophilic poroid cells, with a lower proportion of larger, squamous, eosinophilic cuticular cells, which are lining ductal structures with an eosinophilic luminal cuticle. In most cases of poromas, cuticular cells represent a small proportion of the neoplastic aggregates. Read More

Targeted molecular profiling reveals genetic heterogeneity of poromas and porocarcinomas.

Pathology 2018 Apr 18;50(3):327-332. Epub 2017 Dec 18.

Institute of Pathology, University of Heidelberg, Heidelberg, Germany; German Cancer Consortium (DKTK), Heidelberg, Germany. Electronic address:

The genetic landscape of rare benign tumours and their malignant counterparts is still largely unexplored. While recent work showed that mutant HRAS is present in subsets of poromas and porocarcinomas, a more comprehensive genetic view on these rare adnexal neoplasms is lacking. Using high-coverage next generation sequencing, we investigated the mutational profile of 50 cancer-related genes in 12 cases (six poromas and six porocarcinomas). Read More

Periungual Eccrine Poroma Masquerading as Ingrown Toenails .

J Am Podiatr Med Assoc 2017 Nov;107(6):551-555

Eccrine poroma is a rare benign adnexal neoplasm originating from a portion of the intraepidermal eccrine sweat gland duct and the acrosyringium. Typically, the lesions are asymptomatic, slow-growing nodules, which may be found in any sweat gland-bearing area. Multiple red lacunae, glomerular vessels, hairpin vessels, flower- and leaf-like vascular patterns, a polymorphic vascular pattern, globule/lacunae-like structures, a frog egg-like appearance, and comedo-like openings have been defined as characteristic dermoscopic patterns of the disease.
