Papular pityriasis rosea with palmar involvement an atypical presentation

RADHA RAJA PRABHA KUMARASAMY

Abstract


Abstract : Pityriasis rosea is a self limiting exanthem of
possible viral origin, usually lasting for 4 to 7 weeks. Many
atypical forms of pityriasis rosea have been described in
literature. We describe a papular variant of pityriasis rosea
with palmar involvement. A twenty eight year old male
presented with complaints of generalized itchy skin lesions for
4 days and history of exposure to white cement 7 days back.
It was initially thought as an allergic contact dermatitis to
cement. On dermatological examination there were multiple
erythematous papules over chest, back and proximal portions
of both upper limbs and multiple erythematous scaly patches
over both lower limbs and a few of them showed peripheral
collarette of scales. Scaly eruptions were also observed over
the palms. Skin biopsy was done and the patient was treated
with emollients. On follow up after 3 weeks the lesions got
resolved spontaneously and histological examination was
suggestive of pityriasis rosea.
