Porom

PoromPoromul is a benign neoplasm composed of annexes that shows differentiation of tubular epithelial cells. Malignant variant is called porocarcinom poromului. Apocrine Poromul is more common than the eccrine. Poromul acrospiromului spectrum belongs, with nodular hidradenoamele, hidradenoamele clear cells, and dermal duct tumors Simplex hidroacantomul.Poromul manifests as a solitary nodule or papule. Most lesions are asymptomatic, but may be accompanied by minor pain. Rarely the patient develops multiple poroame simultaneously, a phenomenon known as poromatoza. Poroamele multiple negative can become a cosmetic issue.
Poromul not require medical treatment, they are treated by surgical excision. There are no complications associated with poromul. The prognosis is favorable because the lesions have clinical significance. Even poromatoza not associated with other anomalies. The risk of malignant transformation of a porom is minimal and is considered to be similar to that of normal skin.
Pathogenesis and causes
Poromul is a benign neoplasm that shows differentiation poroida. Malignant variant is porocarcinomul. Poroamele appear only on the skin and does not affect other tissues.
Signs and symptoms
Poromul can occur at any age but is typical of adult age. Are asymptomatic and manifest as stable or nodule with some slow growth. Some are associated with pain. Poroamele are some of the many types of benign neoplasms may occur secondary annexes printrun nevus sebaceous. They look like colored papules or nodules under the skin 2 cm. Occasionally may be pigmented. Lesions may protrusion erosion or ulceration.
Diagnosis
Blood examinations are not needed for this lesion. Poromului diagnosis can not be placed solely on history and clinical examination. Diagnosis is established by histopathology.Histological examination. Most poroame tend to be small, consisting of di cuboid epithelial cells. Neoplastic cells have eosinophilic cytoplasm. Areas of ductal differentiation occurs as a tube lined by a thick cuticle and sometimes eosinophilic cytoplasmic vacuoles. Rarely shows focal necrosis and a well-vascularized stroma-combination that thinks malignant.The differential diagnosis is made with urmataorele aefctiuni: seborrheic keratosis, squamous cell carcinoma, trichilemoma, hidradenom, acrospirom, hidradenom poroid.
Treatment
Poromul not require medical treatment, but surgical excision. Poromului prognosis is favorable because the lesions shows no known clinical significance. Multiple-poroamele Poromatoza not associated with other anomalies. The risk of malignant transformation is minimal.
