Diagnosis

Differential diagnosis

Need to be distinguished from melanin, melanin is a common symptom of many diseases, need to go to the hospital for diagnosis and treatment.

1. Endocrine diseases: due to excessive melanocyte stimulating hormone (MSH) and adrenocorticotropic hormone (ACTH), such as Addison's disease, Cushing's disease, Nelson's syndrome, ovarian tumor, malignant pheochromocytoma, and long-term Treated with ACTH. During pregnancy, the use of estrogen and estrogen-containing contraceptives is also more common in melanin pigmentation.

2, metabolic diseases: such as hemochromatosis, allergic dermatitis of various types of porphyria, hepatolenticular degeneration, skin amyloidosis, high snow disease and other symptoms of melanin deposition.

3, nutritional diseases: melanin deposition will have vitamin A deficiency, vitamin B12, vitamin C, folic acid, niacin and other lack, malabsorption syndrome.

4, chronic infections: such as malaria, kala-azar, schistosomiasis.

5, tumor: seen in the production of ectopic ACTH and MSH tumors, such as lung cancer, pancreatic cancer, advanced malignant melanoma, advanced cancer of the cancer. Melanosis is occasionally seen in Hodgkin's disease, lymphosarcoma, and chronic lymphocytic leukemia.

6, connective tissue diseases: can be found in rheumatoid arthritis, still disease, generalized scleroderma, dermatomyositis, systemic lupus erythematosus.

7, drug-induced melanin deposition: seen in long-term use of chloroquine or hydroxychloroquine, chlorpromazine, butyl sulfonate (busulfan), nitrogen mustard, cyclophosphamide, arsenic, antimony, lead and so on.

8, skin lesions melanin deposition: skin acute and chronic infection, acanthosis nigricans, Riehl (Riehl) melanosis, tar black disease and reticular pigmented skin heterochromia.

9, other: chronic liver disease, cirrhosis, chronic renal insufficiency, Whipple disease and other melanin deposition phenomenon.
