A 12-year-old boy presented to us with numerous well-defined hypopigmented macules over the lower part of the face, neck, trunk and proximal parts of limbs [Figure - 1] present for the last 6 months. Some had coalesced to form large patches but most of the lesions on the back were aligned along the long axes of ribs in a stricking "Christmas tree" pattern [Figure: 2]. The lesions were asymptomatic and slowly progressive while the sensations were intact. There were no features of nerve involvement. A diagnosis of pityriasis rosea was made at this juncture.
However, there was history of a prolonged continuous fever for 5 months with swelling in the left side of abdomen about 4 years before the onset of skin lesions. This was successfully treated with about 20 intramuscular injections of pentavalent antimony after being diagnosed as kala-azar. The patient belonged to Ramnagar (UP) which is an endemic area for kala-azar.
The histopathological examination of the biopsy specimen taken from a lesion showed in the upper dermis an infiltrate of lymphocytes, plasma cells and histiocytes. The slit-skin smear examination was inconsequential. The diagnosis was changed to post-kala-azar dermal leishmaniasis (PKDL). This case is being reported because of its peculiar resemblance to the post-inflammatory changes of pityriasis rosea.
