PITYRIASIS ROTUNDA

By Gary M. White, MD


Pityriasis rotunda presents as multiple, strikingly circular, scaly "ichthyosiform" lesions. It has been reported to be associated with malignancy (e.g. hepatocellular carcinoma, carcinoma of the esophagus, stomach, or prostate, CLL, myeloma etc.) and may clear when the neoplasm is treated[AD 1983;119;607]. Other patients have had tuberculosis, HIV and trypanosomiasis. The common thread may be chronic systemic disease and weight loss [CED 1985;10;407]. It has been reported more commonly in Oriental and Black patients but they can occur in whites. The course is chronic, lasting many years.

Clinical

The patient presents with multiple, strikingly circular, scaly "ichthyosiform" lesions.

Treatment

When associated with malignancy or internal disease, treatment of that disease and improvement of the functional and nutritional status of the patient often clears the PR. Anecdotal success of 10% lactic acid lotion, acitretin and vitamin A have been reported.
