Is melanocytic cancer a proliferation?
Few studies have investigated the biologic potential of atypical melanocytic proliferations. It is possible that most lesions currently reported as atypical melanocytic proliferation (AIMP or SAMPUS) are in fact benign, and that their significance lies in the potential pitfall for overdiagnosis of malignant melanoma.
What is the meaning of melanocytic?
(meh-LAN-oh-site) A cell in the skin and eyes that produces and contains the pigment called melanin. Enlarge.
What does borderline melanoma mean?
Background: The borderline melanocytic tumor (BMT) is a morphologically and biologically indeterminate melanocytic proliferation manifesting worrisome architectural features and cytologic atypia exceeding that encountered in melanocytic nevi yet insufficient to warrant designation as melanoma.
What is melanocytic nevus of trunk?
Melanocytic nevi are benign neoplasms or hamartomas composed of melanocytes, the pigment-producing cells that constitutively colonize the epidermis.
What does a melanocytic nevus look like?
Common nevi are harmless collections of colored cells. They typically appear as small brown, tan, or pink spots. You can be born with moles or develop them later. Moles that you’re born with are known as congenital moles.
Which is the best description of a melanocytic lesion?
Melanocytic lesions. A melanocytic lesion ( blue nevus ). H&E stain. (WC/Nephron) Melanocytic lesions are commonly encountered in dermatopathology and an area which causes some difficulty, i.e. it is hard to decide in some cases whether a lesion is benign (e.g. Spitz nevus) or malignant ( malignant melanoma ).
What are the nevus of a melanocytic mole?
A benign mucocutaneous lesion that contains nevus cells and nevus cell nests. A melanocytic nevus that is not congenital or not present at birth. (E.g., junctional nevus, compound nevus, intradermal nevus.) A mole that owes its deep blue colour to spindle-shaped melanocytes deep in the dermis, caused by the so-called Tyndall effect.
Can a benign melanocytic lesion be congenital or acquired?
Proliferation of melanocytes may result in congenital or acquired benign melanocytic naevi. These present as persisting macules, papules, plaques and nodules. Melanocytic lesions may be due to:
What kind of skin cancer is an atypical melanocytic mole?
Atypical melanocytic lesions are pigmented moles that have been found to have abnormal cells and are assumed to be at risk for developing into a malignant melanoma.
