A 57-year-old woman with Fitzpatrick skin type V presented with a 5-month history of tender enlarging lesions on the anterior neck. She reported excision of a lesion at this site 14 years before. Examination revealed an 85-mm scar on the anterior neck. Firm tender subcutaneous papules and nodules were noted at two sites adjacent to the scar measuring 29 by 17 mm and 30 by 13 mm (Figure 1).

Eccrine angiomatous hamartoma (EAH) is a rare, benign cutaneous tumor. It is characterized by the proliferation of the eccrine gland elements that are closely associated with capillary proliferation. Patients usually present with a solitary nodule on the extremities that appeared at birth or during the prepubertal years. We report a rare case of EAH in a 13-year-old boy, with clinical features ...

in this case report we will describe a rare association between anhyrotic ectodermal dysplasia (aed) and immunodeficiency and autoimmunity [in our case: idiopathic thrombocytopenic purpura (itp) and crohn disease]. aed is a rare congenital disorder characterized by sparse hair, abnormal teeth and anhidrosis due to lack of eccrine glands. the survey of 87 cases with (aed) revealed only one irrit...

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 38-year-old woman is described who presented with a slowly growing mass on the posterior aspect of the left ear. Excision and histopathologic evaluation revealed a pleomorphic adenoma (PA) originating from heterotopic salivary gland tissue. Many authors have presented cases of PAs originating from ceruminous glands in the external auditory canal or of so-called chondroid syringoma originating...

Abnormal ductal NaCl absorption has been known as the only defect in cystic fibrosis (CF) sweat glands. We have fortuitously found that the secretory portion of CF sweat glands is also abnormal in that it failed to show a sweating response to beta adrenergic stimulation (isoproterenol, [ISO]) both in vivo and in vitro. For the in vitro sweat test, eccrine sweat glands were isolated from skin bi...
