	'''Porocarcinoma''', also known as eccrine porocarcinoma, is a rare type of [[skin cancer]] that originates from the [[eccrine sweat gland]]s. It is considered a [[malignant]] form of [[poroma]], a benign sweat gland tumor. Porocarcinoma is most commonly found in the elderly population and can occur anywhere on the body, although it frequently appears on the lower extremities.

	== Clinical Presentation ==		== Clinical Presentation ==

	Porocarcinoma typically presents as a solitary, slow-growing [[nodule]] or [[plaque]] that may be [[ulcerated]] or [[bleeding]]. The lesion can vary in color, appearing as red, pink, or brown. Due to its nonspecific appearance, porocarcinoma can be mistaken for other skin conditions such as [[basal cell carcinoma]], [[squamous cell carcinoma]], or [[melanoma]].

	Porocarcinoma arises from the intraepidermal portion of the eccrine sweat glands. The exact cause of porocarcinoma is not well understood, but it is believed to be associated with [[genetic mutations]] and [[ultraviolet radiation]] exposure. The tumor cells exhibit atypical features and can invade surrounding tissues, leading to potential [[metastasis]].		Porocarcinoma arises from the intraepidermal portion of the eccrine sweat glands.

	The diagnosis of porocarcinoma is confirmed through a [[biopsy]] and [[histopathological]] examination. Under the microscope, porocarcinoma is characterized by atypical cells with ductal differentiation.

	The primary treatment for porocarcinoma is [[surgical excision]] with clear margins.

	The prognosis for porocarcinoma depends on the stage at diagnosis and the presence of metastasis. Early detection and complete surgical removal generally result in a favorable outcome.

'''Porocarcinoma''' is a rare type of [[skin cancer]] that originates from the [[sweat glands]]. It was first described in the medical literature by Pinkus and Mehregan in 1963. Porocarcinoma can occur anywhere on the body but is most commonly found on the lower extremities, particularly the feet.
