| The development of an elevated nodule within the area of pigmentation indicates the change to vertically invasive lentigo maligna melanoma. |
|
| Lentigo maligna melanoma is where a patch of lentigo maligna develops a papule or nodule signalling invasive tumour. |
|
| Slow-growing variant of melanoma arising in a premalignant lesion, lentigo maligna, which appears on the sun-exposed skin of elderly people. |
|
| Changes to deep-black colour and elevation or slight infiltration suggest lentigo maligna melanoma. |
|
| Other risk factors include atypical mole syndrome, giant congenital melanocytic naevi, lentigo maligna and a positive family history of malignant melanoma. |
|
| In conclusion, a small decrease of the pigmentation of the lentigo on the back of the hand was seen while the spot under the eye was greatly improved. |
|
| Slowly growing premalignant disease due to proliferation of atypical melanocytes within the epidermis, which can progress to lentigo maligna melanoma. |
|
| The type of patch that develops with age is called age spot, lentigo, or liver spot. |
|
| Some of the more common skin problems among the elderly include dry skin, seborrheic keratosis and actinic lentigo. |
|
| In lentigo maligna, the most frequent cell type is a spindled hyperchromatic melanocyte with scant cytoplasm. |
|
| Excessive melanin production occurs in melasma, lentigo, nevocellular nevi and malignant melanoma, whereas the loss of melanocyte function leads to vitiligo. |
|
| Lentigo maligna, discussed above, is commonly located in sun-damaged areas on the heads and necks of elderly persons. |
|
| Lentigo is not dangerous and will not deteriorate. |
