Eccrine Porocarcinoma (ECP) is a malignant tumour arising from the intraepithelial ductal parts of the sweat gland. It has also been described as malignant hidroacanthoma simplex, sweat gland carcinoma, malignant intra-epidermal eccrine poroma, eccrine poroepithelioma, dysplastic poroma, malignant syringo acanthoma and porocarcinoma. Treatment with wide local excision but metastatic lesions can...

Sir, Eccrine angiomatous hamartoma (EAH) is a rare benign hamartoma of eccrine glands and blood vessels. It most commonly develops before adulthood as a single, slowgrowing lesion on the extremities. We describe here a case of adult-onset EAH with generalized multiple hairy reddish-brown indurated plaques with a rapidly progressive course. As the lesions showed histopathological findings such a...

Nevus sebaceous is a congenital, benign hamartomatous lesion, characterized by a yellowish to skin-colored, hairless, verrucous plaque on the head and neck region. In later life, a secondary tumor, either benign or malignant, can develop within nevus sebaceous. Eccrine poroma developing on nevus sebaceous is extremely rare. There are few case reports of eccrine poroma developing within nevus se...

Soft, skin-mounted microfluidic devices can collect microliter volumes of eccrine sweat and are capable in situ real-time analysis different biomarkers to assess physiological state health.

SUMMARY We report a rare case of cystic eccrine spiradenoma in the finger. A 46-year-old man presented with a cystic mass in his left index finger. Clinical assessment along with the investigation pointed toward a diagnosis of a ganglion. However, excisional biopsy of the mass revealed histopathological findings of cystic eccrine spiradenoma. Very few cases of eccrine spiradenoma have been repo...

Eccrine syringofibroadenoma is a rare adnexal tumor of eccrine ductal differentiation with variable clinical features. It manifests as either a solitary or multiple papules and nodules arranged in a symmetrical or linear pattern. The anatomical distribution is wide and includes the face, trunk, extremities, and rarely the nails. Histopathological findings show anastomosing cords and strands of ...

We describe a healthy 69-year-old Japanese man with generalized neutrophilic eccrine hidradenitis (NEH). He visited our outpatient clinic with a 15-year history of disseminated pruritic papules on his trunk and extremities; the eruptions, however, were limited to the summer months. Histological findings reveal a dense accumulation of neutrophils around the sweat glands with degenerated secretar...

Giant Vascular Eccrine Spiradenoma (GVES) is a rare variant of Eccrine Spiradenoma (ES), a tumor that develops from the sweat gland. It differs from Eccrine Spiradenoma in its larger size and vascularity as well as propensity for bleeding and ulceration, which may cause a clinical misdiagnosis of vascular lesion or malignant tumor. All previously reported cases in English literature have been i...

Eccrine Poroma is a rare benign adnexal tumor. It presents the problem of differential diagnosis with several entities. Dermoscopic features are suggestive and may guide diagnosis. We report new observation. A 44-year-old woman, presented an asymptomatic lesion on dorsal side left foot for 2 years. Clinically nodule was brownish, well delimited superficial erosions, firm palpation. Dermoscopy s...
