Eccrine sweat glands are derived from the epidermis.10 From the epidermis, they descend to the junction of the dermis and subcutis.10 Each eccrine unit consists of a hollow tube bound proximally by a secretory coil and distally by its opening onto the skin surface.10 The ends of the tube are connected by a straight duct, known as the syrinx, which traverses the dermis.10 The intraepidermal portion (acrosyringium) spirals to its opening on the surface.10 Hence, tumours of the syrinx are called syringomas
, and tumours of the acrosyringium are termed poromas.10
It also removes epidermal lesions and can smooth out syringomas
, nevi, and seborrheic keratoses, said Dr.
of the upper extremities with the onset in the sixty decade.
When these tumors originate in the salivary glands, they are referred to as pleomorphic adenomas; when they originate in the sweat glands, they are referred to as chondroid syringomas
. Chondroid syringomas
may be preceded by trauma and rarely prove to be malignant.
are rare skin adnexal tumor, which can have either a benign or malignant behavior.
Pleomorphic adenomas come in the differential diagnosis of chondroid syringomas
but in contrast to those syringomas
arise from sweat glands.8 Based on the histopathological differences chondroid syringomas
have eccrine and apocrine variants.9 Mills reported that mixed tumors are monoclonal neoplasms with replicating cells that can differentiate towards mesenchymal or epithelial components and this accounts for the histological differences of the mixed tumor of the skin.10 The treatment of choice for chondroid syringoma
is wide surgical excision.11 Because of the lobulated nature of the tumor, the margins of the normal tissue should also be included with the excision to ensure complete removal of the tumor.11
with deep extension: a potential histopathologic mimic of microcystic adnexal carcinoma.
are benign intraepidermal tumour of eccrine sweat ducts mostly found in women at the time of adolescence.
