The sympathetic skin response can be measured across the hands and feet with a simple bio amplifier. Controlled by the sympathetic nervous system, this response results from the activation of the eccrine sweat glands by many types of stimuli. This classical clinical test is used to evaluate peripheral neuropathies caused by a wide range of diseases, and can easily be adapted to teach a range of...

Fig 1. Axillary eccrinehidrocystomas. Involving thepatient’s bilateral axillae are dozens of confluent, smooth, yellowto flesh-colored papules. INTRODUCTION Hidrocystomas are small, thin-walled, benign cystic growths of the sweat glands, typically found on the face, and most often occurring on the periorbital and malar skin. These lesions may proliferate and increase in size in summer months an...

Introduction: Bullous pemphigoid (BP) is one of the most prevalent autoimmune blistering diseases, and believed to be mediated by autoantibodies and complement. The disorder is categorized by the development of urticarial plaques surmounted by subepidermal blisters, and the deposition of immunoglobulins and complement at the basement membrane zone (BMZ) of the skin. Case Report: A 70-year-old m...

Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare variant of adenoid cystic carcinoma (ACC) which originates from the skin adnexa, most probably eccrine and apocrine glands. This tumor has a head and neck predilection and also occurs in the chest, abdomen, back, and perineum. We hereby present a 63-year-old man with PCACC located on the shin. No previous similar case has been reporte...

Cutaneous ciliated cyst are relatively rare benign lesions, found in the dermis or subcutis of lower extremities young females their second and third decades. The cysts typically lined by cuboidal to columnar epithelium, showing pseudostratified areas focal squamous metaplasia is occasionally present. Immunohistochemical studies have demonstrated that can be PR ER positive, similar epithelia fa...

Background: Cutaneous appendageal tumours can arise from either the eccrine, apocrine, hair follicles or the sebaceous glands. Majority of the tumours are benign. Final diagnosis requires a good clinical as well as histpathological correlation. The aim of the present study was to assess the clinicopathological characteristic of these tumours. Materials & Methods: The present study was a retro-p...

Hidradenomas are tumours that arise from the adnexal structures, both eccrine and apocrine and are histologically benign. The tumours that arise from eccrine differentiation are known as poroid hidradenomas and when they arise from the apocrine glands they are called nodular hidradenomas. In our centre a 13-year-old boy presented with a slow-growing, painless erythematous fungating nodule on th...

Eccrine syringofibroadenoma (ESFA) is an uncommon benign adnexal neoplasm which derives from cells of the acrosyringium of eccrine sweat glands. The clinical appearance is nonspecific but the histological features are typical. Five clinical subtypes of ESFA exist: (1) solitary ESFA; (2) multiple ESFA associated with ectodermal dysplasia; (3) multiple ESFA without cutaneous features; (4) unilate...
