Eccrine porocarcinoma is a rare cutaneous neoplasm that mainly affects elderly people and grows slowly over a long period of time but often experiences an accelerated growth phase. Eccrine porocarcinoma may arise de novo or evolve from a pre-existing benign eccrine poroma. We reported a 86-year-old Japanese woman presenting with two reddish-colored pendulated lesions on a keratotic light brown ...

Eccrine poromas arise from the intraepidermal region of the eccrine sweat duct and most often occur as a benign solitary tumor. There are few reports of the occurrence of multiple lesions, defined as poromatosis, which may present in patients who have undergone radiotherapy and/or polychemotherapy. We report the case of a 43-year-old male with a history of mantle cell lymphoma who had undergone...

Eccrine syringofibroadenoma (ESFA) is a rare neoplasm that usually presents as a solitary, often large, hyperkeratotic nodular lesion with predilection for the extremities. Histologically, there are thin anastomosing epithelial cords and strands forming a lattice and connected to the undersurface of the epidermis. Ducts are presented within the tumor. Between the strands, there is a rich fibrov...

BACKGROUND Eccrine poroma is a benign neoplasm that can mimick a malignant neoplasm dermoscopically. The characteristic vascular pattern of this tumor has not been established. OBJECTIVE To evaluate dermoscopic features of non-pigmented eccrine poroma in Mexican patients. METHOD We retrospectively studied histologically proven cases of eccrine poroma from three Mexican hospitals analyzed by...

Eccrine poroma is described as a benign neoplasm originating from the intraepidermal eccrine duct of sweat glands. This tumor is known to arise in bare skin areas, but more rarely appeared in head and neck region. A 54-year-old female presented with a mass on the retroauricular aspect of the left auricle. There was a soft, protruding, and purple-colored, solitary mass of about 1.0×1.0 cm in siz...

Eccrine porocarcinoma is a rare malignancy of the eccrine sweat gland. It is usually found frequently on the lower extremities, and it affects both sexes equally usually in the sixth to seventh decade. In our case, we present a 42-year-old male patient with a recurring exophytic tumor on the right lower extremity without local extension. The initial tumor was biopsied, excised and diagnosed as ...

Eccrine syringofibroadenoma is a very rare benign tumour of acrosyringium of eccrine sweat duct. Based on the evidences of known etiological factors, two forms have been proposed; reactive and nonreactive. Reactive forms are rarer, and on even rarer occasions, trauma complicated by secondary nonspecific infections may lead to the development of reactive eccrine syringofibroadenoma, as in our ca...

Eccrine hidrocystomas are benign tumors of the sweat glands that arise from cystic dilatation of the excretory sweat duct. Exact diagnosis requires biopsy and histopathologic examination, from which arises risk of scarring. Dermoscopy could be a useful tool in diagnosing eccrine hidrocystomas. Herein we aim to present dermoscopic features in three female patients with multiple lesions on the fa...
