Eccrine syringofibroadenoma is a rare benign neoplasia derived from acrosyryngium cells of the eccrine sudoriferous glands. It affects the extremities of elderly individuals as solitary tumors, or may also present as multiple lesions. There are controversies about the pathogenesis and differentiation of the tumor. Eccrine syringofibroadenoma has been associated with subjacent conditions, such a...

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...

Squamoid eccrine ductal carcinoma is an eccrine carcinoma subtype, and only twelve cases have been reported until now. It is a rare tumor and its histopathological diagnosis is difficult. Almost half of patients are misdiagnosed as squamous cell carcinoma by the incisional biopsy. We report the thirteenth case of squamoid eccrine ductal carcinoma. Female patient, 72 years old, in the last 6 mon...

Eccrine hidrocystoma is a benign cystic tumor of the eccrine sweat gland duct. It occurs mainly on the face and more common in elderly women with male:female ratio of 1:8. It is characterized by a chronic course and seasonal variability with aggravation in summer season. It presents as an asymptomatic, flesh colored translucent facial papules. Here we present a case of a 50 year old male with m...

A "poroid cell neoplasm" is a general term used to describe nodular tumors that consist of poroid cells and cuticular cells. Eccrine poroma, the most common type neolplasm, tumor continuous with epidermis extends into dermis in cord-like fashion. This almost always seen as single lesion, cases multiple eccrine poromas (eccrine poromatosis) being exceedingly rare. In fact, there have only been a...

Eccrine poroma can mimic benign and malignant melanocytic and non-melanocytic lesions. To date, little is known about the dermoscopic features of this condition. Seven histopathologically proven cases of eccrine poroma were examined using dermoscopy by three independent dermatologists. Both glomerular and hairpin vessels were observed in 71% of cases, whereas linear irregular vessels were obser...

It is well known that eccrine sweating is attenuated in patients with atopic dermatitis (AD). We have reported by using proteome analysis that gross cystic disease fluid protein 15 (GCDFP15), a substance secreted from eccrine sweat glands, is decreased in tape-stripped stratum corneum (SC) samples from AD patients. The aim of this study was to evaluate GCDFP15 production by eccrine glands with ...

The differential diagnosis among the most frequent skin tumors, base-cell carcinoma and squamous-cell carcinoma, and the rare types, the sweat gland carcinomas, is fundamental for the early diagnosis and prognosis of a patient. These are classified as eccrine and apocrine, and the eccrine is the most common type. The eccrine sweat glands are most abundant in the palms of the hands and the feet ...

An eccrine poroma is a common benign tumour arising from the eccrine sweat gland duct epithelium in the dermo-epidermal region. Its occurrence in the neck region in pediatric age group is a rare entity. Here we report a case of an eccrine poroma in the retro-auricular area just below and behind the lobule of the left pinna in a nine years old child.
