Coalescing Green and Yellow Papules on the Feet

Arch Dermatol. 2000;136(1):113-118. doi:

Paraffin-embedded sections of the exfoliated skin stained with hematoxylin-eosin showed a pink amorphous substance within the stratum corneum, with overlying parakeratosis. A periodic acid–Schiff stain was negative for fungal elements, and bile and Ulex europaeus agglutinin stains were negative for bile and for erythrocyte glycoprotein, respectively. Benzidine, which selectively stains hemoglobin,1 focally stained the outlines of ovoid anucleate bodies within the amorphous, intracorneal substance.
