Sweet's syndrome associated with multiple myeloma.
ABSTRACT Sweet's syndrome (SS) is an acute febrile neutrophilic dermatosis. It may be paraneoplastic in 10 to 20% of cases. Association with multiple myeloma (MM) is uncommon.
We report on a 73-year-old woman that developed SS 2 months after being diagnosed with IgG MM. Cutaneous lesions improved rapidly after chemotherapy for the MM. No recurrence of SS has taken place during the subsequent 2 years.
Association of SS with MM has been rarely described in the literature. Only 14 cases of SS with MM have been reported. The secretory status of the MM may influence the occurrence of SS. SS seems to be related to IgG MM. Patients with IgG MM may have more risk of developing SS than those with other secretory types.

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.Journal of the College of Physicians and Surgeons--Pakistan: JCPSP 01/2011; 21(1):40-2. · 0.32 Impact Factor
