Dermoscopy and histopathology of eccrine poroma: (A) Clinical presentation of a nonpigmented eccrine poroma sensu stricto as a pink nodule located on the foot (B,C) Dermoscopy shows milky red areas (light blue arrow), milky red globules (dark blue triangle), and dotted vessels (black arrow) (original magnifications ×20 and ×40, respectively). (D,E) Histopathologically, the neoplasm consists ...
Poroma. Poromas are a group of benign growths of poroid differentiation, i.e. derived from cells of the terminal duct and connected to the epidermis. They can be of either eccrine or apocrine lineage. They may present as papules (bumps), plaques (thickened patches like seborrhoeic keratoses), or nodules (lumps). Names used to describe poromas ...
Poroma (poroid tumor), a benign adnexal tumor, usually originates from the terminal duct of sweat glands.[1] Initially, Pinkus et al described poroma and its differentiation in 1956, which was initially believed to be of eccrine origin.[2] However, further research has revealed cases of apocrine, sebaceous, and follicular differentiation.[3]
The vascular patterns commonly seen in eccrine poroma are the polymorphic, glomerular, linear irregular, leaf and flower-like and looped or hairpin variants. The leaf and flower-like pattern appears to be relatively unique to the poroma. Mosaic pattern is not observed in eccrine poroma (Clin Case Rep 2021;9:1601). Comment Here Reference: Poroma
These lesions are typically located on palmar or plantar skin, but may occur in any area where eccrine glands are present. Clinically, a poroma is described as a sharply demarcated 2-12 mm papule or nodule, usually flesh or pink in color, though a pigmented variant has been reported (Figure 1). Figure 1.

Poroma is a benign adnexal neoplasm of the terminal sweat gland duct. Although poromas have traditionally been thought to originate from the eccrine sweat gland, there have been cases of apocrine etiology as well. Eccrine and apocrine poromas typically present as erythematous or flesh-colored nodules on the palms and soles.
Poroma (Acrospiroma, hidradenoma) Clinical presentation. The term " poroma " refers to a group of cutaneous appendageal tumors with terminal ductal differentiation. Historically classified as derivatives of eccrine glands, evidenced by the frequent use of the term "eccrine poroma," they may also derive from apocrine glands.
In a study conducted by the International Dermoscopy Society , 113 poromas from sixteen contributors were examined dermoscopically and compared to 106 clinically matched control lesions.The features found to be most useful for the diagnosis of poroma included branched vessels with rounded endings (30.1%), white interlacing areas around vessels (23%), yellow structureless areas (31.9%), and ...
Dermoscopic features associated with poroma include branched vessels with rounded endings, white interlacing areas around vessels, yellow structureless areas, and milky-red globules .Additional findings common but not specific for poromas include polymorphous vessels, blood spots, erosions/ulcers, and milky-red areas.
Poroma is a type of skin tumour that develops from sweat glands. It is usually found on the palms, soles, and extremities, and can be diagnosed by excision or biopsy.
