“…2 Its pathogenesis may be secondary to trauma scars. 3 In our patient the nodule localized on the face, which suggest the implication of UV radiations. Although Blue-gray ovoid nests and arborizing vessels are known as a specifics dermoscopy signs of Basal Cell Carcinoma, They have been found recently in pigmented poroma.…”

Eccrine poroma is an uncommon appendage skin neoplasm originating from the terminal distal portion of the sweat glands annexed to the skin. This benign affection commonly appears as a skin colored papules or nodules localized on the extremities. Its pathogenesis may be secondary to trauma scars. We present a case of pigmented eccrine poroma localized on the face, with clinic and dermoscopic appearance similar to basal cell carcinoma.

“…Most frequently EP is skin-colored, pink-red, and, when it is pigmented, it can be described as blue or even black [ 24 ]. Although poroma affects predominately volar skin, there have been cases reported on other areas, like the trunk, face, vulva, eyelids, and even subungually [ 3 , 25 , 26 , 27 ]. This predilection of acral surfaces could be justified by the fact that on these sites eccrine glands are denser and more numerous.…”

Eccrine Poroma: Pathogenesis, New Diagnostic Tools and Association with Porocarcinoma—A Review

et al. 2023

Eccrine poroma (EP) is a relatively rare benign adnexal neoplasm that usually affects elderly patients. Its pathogenesis is still under investigation, but recent gene studies have revealed gene fusions as key incidences resulting in oncogenetic pathways. It often presents as a solitary, firm papule, mostly asymptomatic, located on the soles or palms. Due to its clinical and dermoscopic variability, it is characterized as the great imitator. We performed a literature review, aiming to summarize current data on the pathogenetic mechanisms, new dermoscopic features, and novel diagnostic tools that may aid in early diagnosis and proper management of this rare adnexal tumor. Furthermore, we reviewed the possible pathogenetic associations between EP and its malignant counterpart, namely eccrine porocarcinoma. This systematic approach may aid in understanding the pathogenetic mechanisms and how to use novel histopathologic markers and imaging methods to overcome the diagnostic dilemma of this rare tumor.

“…Its incidence is approximately 0.001%–0.008% of all skin biopsy specimens and usually presents as a painless, solitary lesion, usually affecting the palms, the soles, or the feet [ 2 ]. EP is less commonly reported in the finger, posterior side of the hand, chest, forehead, nose, and scalp [ 3 ]. To our knowledge, two cases of poroma on the buttock region were reported in the literature but no recurrent poromas were reported at this anatomical site.…”

“…The pathogenesis is unclear, but its etiology is associated with a history of trauma, radiation exposure, viral infection, or actinic damage [ 3 ]. The typical clinical presentation is a slow-growing asymptomatic dome-shaped nodular lesion, plaque, often uncolored, or pigmented [ 4 ].…”
