What is Melanoma of the Small Intestine?Malignant melanoma of the skin is a type of cancer that can develop as a result of metastasis of skin cancer that originates from the abnormal growth of melanin-producing cells of the skin. But in rare cases, melanoma of the small intestine can primarily originate from the mucosa of the small intestine.
Disease CausesThere is no well-known cause; however certain hereditary and genetic mutations along with prolonged exposure to the ultraviolet rays of the sun, and spending more time in tanning beds are potential risk factors for the development of small intestinal melanoma.

DiagnosisThe following diagnostic tests and procedures can be used to make a diagnosis. These are
- Physical examination of the skin to see the site, size, and extent of the tumour
- Dermoscopy (the examination of a skin lesion with a dermo-scope)
- Retinoscopy (Examination of the retina of the eye through retinoscope)
- Biopsy of the skin lesion and histopathology
- Imaging tests such as X-ray, USG, CT-Scan, and MRI (magnetic resonance imaging) of the head neck, arm, legs, and chest to see the extent of the lesion or tumour.
- Endoscopy of the small intestine to detect the melanoma of the skin
