    Pityriasis rotunda as an incidental paraneoplastic finding in two patients with multiple myeloma.
    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

    Cutaneous paraneoplasia.
    Clin Dermatol 2011 Sep-Oct;29(5):541-7
    Sector of Dermatology and Post Graduation Course of Dermatology, University Hospital Clementino Fraga Filho andSchool of Medicine, Federal University of Rio de Janeiro, 22280-020 Rio de Janeiro, Brazil.
    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.

To the best of my knowledge, no patient with the characteristic clinico-pathologic features has been reported from the Indian subcontinent. Read More
