title: Paraneoplastic Addisonian pigmentation and acquired ichthyosis as presenting features of multiple myeloma.
abstract: Black brown hyperpigmentation of the mucosae, sunexposed skin, palmar creases and frictional sites (Addisonian pigmentation) is characteristic of Addison disease. However, it can also occur as a paraneoplastic manifestation of tumours like bronchogenic carcinoma. Acquired ichthyosis starts later in life and can also be a paraneoplastic presentation. We report a unique combination of paraneoplastic Addisonian pigmentation and acquired ichthyosis as presenting features in a patient with undiagnosed multiple myeloma. To the best of our knowledge this combination of paraneoplastic dermatosis has not been documented before in multiple myeloma. It is concluded that the presence of more than one suspicious dermatosis may be an indicator of being paraneoplastic requiring necessary work-up.
