Although paraneoplastic phenomena occur frequently in patients with
hepatocellular carcinoma
, cutaneous changes have rarely been reported. During the past two years, ten South African blacks with
hepatocellular carcinoma
and pityriasis rotunda have been seen in a single hospital. The rash affected the trunk, especially the lower back and buttocks. The lesions ranged in size from 1.5 to 25 cm and were always multiple. They had a characteristic circular or arcuate configuration with scaling and varying degrees of hyperpigmentation.
Pityriasis rotunda
may prove to be a useful cutaneous marker of
hepatocellular carcinoma
in South African blacks.

Pityriasis rotunda
is described as persistent, large, sharply defined circular patches of dry ichthyosiform scaling with no inflammatory changes.
Pityriasis rotunda
may be associated with systemic diseases (eg.
hepatocellular carcinoma
). We report a case of pityriasis rotunda in a 19-year-old, otherwise healthy male. The condition started one year prior to his referral. Lesions were distributed over the trunk and upper extremities. Histopathological examination revealed hyperkeratosis, absent granular layer, pigmented basal layer, pigmentary incontinence and perivascular lymphocytic infiltrate. PAS staining for fungi was negative. Treatment of pityriasis rotunda in this case was challenging. When there's an underlying disease, successful treatment of the original disease leads to clearance of pityriasis rotunda lesions.
