Cureus 2020 Feb 4;12(2):e6873. Epub 2020 Feb 4.

Surgery, South Colombian University, Neiva, COL.

Eccrine porocarcinoma is a rare malignant tumor that develops in the eccrine glands, appearing as a primary tumor, or by malignant transformation of an eccrine poroma. It is a carcinoma with high metastatic and recurrent potential; it has the same incidence in both sexes, and mainly affects the elderly. Its diagnosis, rather than clinical, is histological, and due to the rarity of the disease, it is a pathological challenge. Read More

Altered Rb, p16, and p53 expression is specific for porocarcinoma relative to poroma.

J Cutan Pathol 2019 Sep 3;46(9):659-664. Epub 2019 May 3.

Department of Pathology, Michigan Medicine, Ann Arbor, Michigan.

Background: Porocarcinomas are rare aggressive carcinomas that harbor tumor suppressor mutations and must be distinguished from benign entities such as poromas.

Methods: To determine whether altered expression of these genes was diagnostically informative, we examined p53, Rb, and p16 staining patterns in 15 poromas and 16 porocarcinomas.

Results: Poromas consistently displayed diffuse strong expression of Rb in all but one case that displayed focal loss (1/15, 7%), and no evidence of aberrancy in p53 or p16. Read More

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

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.

A synchronous incidence of eccrine porocarcinoma of the forearm and facial squamous cell carcinoma: A case report.

Int J Surg Case Rep 2018 8;42:116-120. Epub 2017 Dec 8.

Department of Pathology, Sultanah Nur Zahirah Hospital, Jalan Sultan Mahmud, 20400, Kuala Terengganu, Terengganu, Malaysia.

Introduction: Cutaneous appendageal tumor can differentiate towards or arise from either pilosebaceous apparatus or the eccrine sweat glands. Appendageal tumors are relatively rare, their clinical appearance is non-specific, and the vast majority are not diagnosed until after excision. Eccrine porocarcinoma (EP), also known as malignant eccrine poroma is a rare adnexal tumor arising from the intraepithelial ductal parts of the sweat gland. Read More

Holocrine Poroma: A Distinctive Adnexal Tumor.

Am J Dermatopathol 2018 Jun;40(6):401-408

Department of Pathology, Montefiore Medical Center, Bronx, NY.

There are 36 cases of complex poroid tumors with folliculosebaceous and apocrine differentiation reported in the literature. The authors evaluated 111 poroid tumors including 63 typical eccrine poromas and 48 poroid tumors with folliculosebaceous elements. Folliculosebaceous poroid tumors (FSPT) had basaloid and squamous cells (100%), ducts with steatocystoma-like cuticles and holocrine secretions (89. Read More

Reticulated acanthoma with sebaceous differentiation mimicking melanoma.

Dermatol Pract Concept 2017 Jul 31;7(3):35-37. Epub 2017 Jul 31.

Department of Dermatology, Mogi das Cruzes University, Mogi das Cruzes, Brazil.

Reticulated acanthoma with sebaceous differentiation (RASD) is a rare, benign cutaneous tumor with peculiar histopathologic characteristics [1]. RASD had been described under various synonyms such as superficial epithelioma with sebaceous differentiation, sebocrine adenoma, poroma with sebaceous differentiation, and seborrheic keratosis with sebaceous differentiation [2]. Clinical differential diagnosis of RASD includes cutaneous superficial epithelial neoplasia such as Bowen's disease, superficial basal cell carcinoma (BCC) and intraepidermal eccrine poroma [1].

A Large Lumbar Adnexal Neoplasm Presenting Characteristics of Eccrine Poroma and Poroid Hidradenoma.

Case Rep Surg 2017 19;2017:9865672. Epub 2017 Sep 19.

Department of Anatomy, Faculty of Medicine, National and Kapodistrian University of Athens, Athens, Greece.

Poroma is a rare benign neoplasm that derives from eccrine sweat glands epithelium. Its histological subtypes, with respect to its position within skin layers, are eccrine poroma, hidroacanthoma simplex, poroid hidradenoma, and dermal duct tumor. Poromas commonly exhibit benign clinical behavior as they are usually small and asymptomatic and do not exhibit malignant behavior. Read More
