An upper lid eccrine hidrocystoma presenting as early childhood progressive ptosis is very rare. We present a 9-year-old female child with droopy right upper lid since birth and progressive increase in symptoms. She had right upper lid ptosis (marginal reflex distance 1 of -1 mm) with fair levator function (8 mm) and abnormal cystic change on the conjunctival side. Computerized tomography imagi...

Eccrine sweat glands are the predominant ectodermal appendage of human skin and essential in thermoregulation. Despite their importance, developmental program cellular interactions that drive eccrine gland formation poorly understood. In mouse volar skin, to which restricted this species, expression transcription factor Engrailed-1 (En1) basal ectoderm is required for specification placodes, wh...

This 66-year-old Iranian gentle man had a one-year history of asymptomatic keratotic papules with a linear distribution on the skin of his right palm near the wrist. On histopathologic examination-cornoid lamella-like parakeratotic columns above eccrine ducts were observed. The acrosyringium was also dilated. The diagnosis was porokeratotic eccrine ostial and dermal duct nevus. The late-onset d...

Apocrine glands are the major type of sweat gland in dogs, and distribution of eccrine sweat glands is limited to footpad (Goldschmidt and Shofer, 1992). Apocrine sweat gland tumors are rather common in dogs and tend to occur on the head, neck and limbs. The Golden Retriever is a breed that shows a predisposition to such tumors (Kalaher et al., 1990). The tumor was greatly resembles its human c...

INTRODUCTION Eccrine porocarcinoma is a very rare type of skin cancer. It is an aggressive dermatological malignancy. We presented a 62-year-old male with long history of a mass in left forearm complicated by distant metastasis and death. A rapid review of literature has been presented. CONCLUSION Eccrine porocarcinoma is a rare but aggressive type of skin disease. It may arise de novo or com...

Eccrine spiroadenocarcinoma is an extremely rare malignant eccrine gland tumor which may masquerade as other more common malignancies such as poorly differentiated squamous carcinoma or metastatic breast cancer. We report a case of an ulcerated axillary skin lesion with bulky adenopathy in a 77 year-old female with a prior history of ipsilateral triple negative breast carcinoma. The clear trans...

Poroma is a rare benign neoplasm that derives from eccrine sweat glands epithelium. Its histological subtypes, with respect to its position within skin layers, are eccrine poroma, hidroacanthoma simplex, poroid hidradenoma, and dermal duct tumor. Poromas commonly exhibit benign clinical behavior as they are usually small and asymptomatic and do not exhibit malignant behavior. Although their his...

INTRODUCTION The purpose of this study was to perform a quantitative fluoroscopic analysis of the coronary sinus ostium and its relationship to the His bundle in patients with and without AV nodal reentrant tachycardia. Sites of slow pathway ablation are often near the coronary sinus ostium, which can be located within a few millimeters of the His bundle. Whether such close proximity of the cor...

A 43-year-old Chinese man presented with generalized hypohidrosis, which he had had since birth, without obvious abnormalities of other skin appendages except a sparse beard and axillary hairs. The sweat test revealed localized sweating on the face, axillae and palms. Histopathologic examination showed that the sweat glands were absent in the forearm and thigh, but some eccrine and apocrine swe...

The distribution and selectivity of complex carbohydrates in the eccrine glands of the digital pads in the North American raccoon (Procyon lotor) were studied using light and electron microscopic histochemical methods, particularly lectin histochemistry. In the eccrine glands, the dark cells exhibited neutral and acidic glycoconjugates with different saccharide residues (alpha-L-fucose, beta-D-...
