DescriptionPortion of skin, with the underlying subcutaneous tissue, showing a melanoma of the areolar connective tissue. From the lumbar region of a female aged 56 years, in whom extensive melanomatosis had followed the removal of a pigmented pedunculated melanoma of the dorsal skin over the ilium. She was also the subject of a carcinoma of the mamma.
