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 ...
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 on medial foot.
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]
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 ...
A poroma is a benign adnexal neoplasm composed of epithelial cells that show tubular (usually distal ductal) differentiation. [] The malignant counterpart of a poroma is referred to as porocarcinoma. [] Poromas historically have been considered glandular adnexal neoplasms of eccrine lineage, and this view is so entrenched that the neoplasm is often referred to as eccrine poroma; however ...
Poroma. Poromas are benign tumors most commonly arising in the palms and soles as red-pink papules or nodules. Poromas generally occur in middle-aged adults with an equal predilection for men and women. Several conditions can be associated with the development of multiple lesions including radiation therapy, chemotherapy, pregnancy and post ...
Poroma is a benign cutaneous tumor derived from the terminal portion of the sweat gland duct. Although it largely remains classified as a neoplasm of the eccrine sweat gland, apocrine etiology has been implicated in some cases. The clinical and histopathologic features of poromas closely parallel those of several other dermatologic conditions.
Poroma is a skin condition that usually appears as a single, slow-growing small bump or patch that might be skin-colored, red, brown, or blue. These growths, while generally painless, can sometimes be slightly tender to touch. They often look like small, blood vessel-rich skin growths, similar in look to a pyogenic granuloma. ...
