A variety of cutaneous abnormalities can be seen in patients with malignant diseases, some of which are infectious, with others representing direct involvement of the skin by the underlying disorder.

This review considers the latter collection of conditions, grouping them by the generic type of malignancy that is usually linked to the paraneoplasia. Read More

Clin Exp Dermatol 2014 Aug 1;39(6):734-7. Epub 2014 Jul 1.

Department of Internal Medicine, Faculty of Health Sciences, University of the Free State, Bloemfontein, South Africa.

Pityriasis rotunda (PR) is an uncommon chronic dermatosis, which may be idiopathic or may be associated with infections or malignancy. We describe the clinical and biochemical findings of two patients with multiple myeloma, who were incidentally diagnosed with PR, and detail the clinical conditions with which this rare paraneoplastic phenomenon may be associated. Although PR is a rare condition, it may be found as a paraneoplastic phenomenon in a range of conditions, and thus should be recognised as an important clinical sign. Read More

Paraneoplasias are frequently the first sign of a subjacent malignant tumor. Although relatively rare, they need to be recognized by dermatologists to make an early diagnosis and improve the prognosis related especially to the neoplasia. This contribution presents the morphologic aspects and the differential diagnosis of the main paraneoplasias, which include acanthosis nigricans, tripe palms, Leser-Trélat sign, acquired ichthyosis, acquired hypertrichosis lanuginosa, pityriasis rotunda, erythema gyratum repens, palmo-plantar keratoderma, Bazex syndrome, and dermatomyositis, hoping to contribute to the familiarity of dermatologists with the identification and early diagnosis of this group.
