eccrine poroma

poroma

 [pŏ-ro´mah]
a tumor arising in a pore.
eccrine poroma a benign tumor arising from the intradermal portion of an eccrine sweat duct, usually on the sole.

ec·crine po·ro·ma

a poroma or acrospiroma of the eccrine sweat glands, usually occurring on the sole of the foot. as a soft reddish nodule composed of basaloid cells and fibrovascular tissue.

eccrine acrospiroma

A benign lobulated skin adnexal tumour arising from a distal excretory duct in the palms and soles of the feet, with minimal eccrine differentiation.

ec·crine po·ro·ma

(ek'rin pōr-ō'mă)
A poroma or acrospiroma of the eccrine sweat glands, usually occurring on the sole of the foot.

eccrine poroma

benign neoplasm of eccrine sweat gland epidermis; 50% present on plantar skin and toes, as a solid, non-painful, slightly red, sometimes pedunculated, slowly enlarging (up to 3 cm diameter) nodule with a warty, ulcerated or bleeding surface; treated by excision biopsy

Histology of excised tissue shows stratified squamous epithelium over fibrocollagenous stroma, cords and wide column of basaloid cell extending into the dermal stroma from overlying epithelium, rich vascularity within stroma in between these cords, confirming the diagnosis of periungual eccrine poroma.
Eccrine poroma, sebaceous hyperplasia, and pilomatrixoma were the most common benign tumors and two sebaceous carcinoma were the only two malignant tumors seen.
However, the final diagnosis, according to histologic and immunostaining methods, was a benign eccrine poroma.
Although eccrine poroma, a tumor derived from the acrosyringium, most often presents on plantar or palmar skin, it may occur at any site containing sweat glands.
It was subsequently confirmed the tumour was indeed that of a benign eccrine poroma and the lesion was excised.
A skin excision biopsy was carried out, whose report was a dermal tumor mass from the lower portion of the epidermis, well de fined, formed by small cuboidal cells without atypia, arranged in well-defined bands that anastomose without barricade, with pigmented areas and few dilated ducts, which are in contact with the resection margins, compatible with eccrine poroma (Fig.
ABSTRACT: Eccrine poroma is a benign tumor which arises from the intraepidermal portion of the eccrine sweat glands.
We considered the possibility of a porocarcinoma, the malignant counterpart of an eccrine poroma.
They include benign adnexal tumors such as trichoblastoma syringocystadenoma papilliferum trichilemmoma sebaceoma nodular hidradenoma hidrocystoma and eccrine poroma.
Cases where significant diagnostic differences were noticed included a suspicious Kaposi sarcoma (case 16), finally reevaluated as a dermatofibroma; an invasive squamous cell carcinoma of the head diagnosed as eccrine poroma (case 21) on final microscopy; and a suspicious low-grade soft tissue sarcoma diagnosed as angioleiomyoma (case 22), which was confirmed with the help of immunohistochemical staining.
Histology shows lobulated tumor masses located in dermis resembling eccrine poroma with two cell types.
Three subtypes of poroid neoplasia in a single lesion: eccrine poroma, hidroacanthoma simplex, and dermal duct tumor.
