::  Nomenclature and morphological features of tumors that develop from melaniebrady tissue ::

A histological study of the removed eyeball revealed in the choroid a black tumor the size of 1x0,4 cm thick consistency  . Microscopically: large polymorphic cells, grouped in alveolar structure. It was found numerous pathological mitoses, and in the cytoplasm of many of them a pigment yellow-brown colour. Your diagnosis:
{
= Melanoma
~ Neuroma
~ Angiosarcoma
~ Neuroblastoma
~ Ganglioneuroblastoma
}

The young woman detected the tumor in the form of a blue-black soft site on the face. Microscopically, the tumor pronounced polymorphism, the tumor is composed of spindle or pleomorphic, distorted cells. In the cytoplasm of many cells pigment is yellowish-brown color. Many mitoses. Your diagnosis:
{
~ Neuroma (Sanoma, neurilemoma)
~ Malignant neuroma
= Melanoma
~ Neuroblastoma
~ Ganglioneuroblastoma
}

 At histological study of malignant melanoma  the prognosis unfavorable duration of the disease associated with the manifestation:
{
=. The tendency of the tumor to vertical growth 
~ In the Tendency of the tumor to a horizontal growth
~ Accumulation in the tumor cells of the pigment
~ The nature of the cellular morphology of the tumors
~ Collapse of the tumor

At the  patient of 17 years found intraoperatively in the liver a tumour of size 4,5x5x3,5 cm of dark brown color. Your preliminary diagnosis.
{
~ Hemangiopericytoma
= Cavernous hemangioma
~ The metastasis of melanoma
~ Capillary hemangioma
~ Lymphangioma
}

The patient on the skin of the trunk found a tumor that had the appearance of brown spot with black drops around. Microscopically it consists of polymorphic atypical cells. In the cytoplasm of most cells is pigment yellow-brown color. Your diagnosis:

{
~ Fibroma
= Melanoma
~ skin Cancer
~ Trophic ulcer
~ Sarcoma
}

A Men 46 years, found a dark colour spot on the scalp. It does not cause discomfort. In recent years, the spot began to increase in size, the pain came, the color was black and brown. Histological examination of the removed tissue revealed the spindle-shaped and pleomorphic cells, with the brown pigment in the cytoplasm. Your diagnosis:
{
= Melanoma
~ Hematoma
~ Hemangioma
~ Basal cell carcinoma
~ carcinoid
}

At ophthalmic examination in a patient 53 years old with complaints of vision deterioration was revealed a tumor formation on the background of the iris of the right eye which is dark brown with indistinct borders, irregular shape, size 10x8 mm, the surface of which upper the iris and partially covers the pupil. In the study of postoperative material, the tumor is composed of pleomorphic atypical cells, in the cytoplasm granules which are yellow-brown in color, there are many mitoses. Your diagnosis:
{
~ Naevus
~ Cyst
= Melanoma
~ Neuroma
~ Leiomyoma
}

The young woman on the skin of the upper extremities revealed three brown spots ranging in size from 0.5 to 1 cm in diameter. They have the appearance of warty growths in shape and slightly elevated above the skin surface. When microscopic examination in the dermis are cells with a large amount of melanin in the form of individual clusters, also there are giant multinucleated cells. Your diagnosis:
{
~ Melanoma
= Intradermal naevus 
~ Mixed naevus
~ Hemangioma
~ involutive naevus (fibrous papule of the nose)
}

A young woman went to the doctor for the spherical protrusion on the nose. Its surface was pigmented. Microscopically examination revealed fibrous tissue, which contains rare giant cells. In the marginal zone, there is nests of nevus cells. Your diagnosis:
{
~ Melanoma
~ Hemangioma
~ Blue naevus
= involutive naevus (fibrous papule of the nose)
~ Mixed naevus
}

At child 7 years on the skin appeared  a formation  in the form of a flat, clearly visible node. Its surface is smooth, pale red. Microscopically, cells with pale cytoplasm and hyperchromatic nuclei forming bundles. The cytoplasm contained pigment yellow-brown in a small amount. Characterized by the presence of multinucleated giant cells with basophilic cytoplasm, resembling the cells of Pirogov-Langans. Your diagnosis:
{
= Melanoma
~ Hemangioma
~ Mixed naevus
~ Blue naevus
~ Fibrous papule of the nose (involutive naevus)
}
