A 66-year-old female with dermatomyositis presented with reddish-brown hyperkeratotic papules and coalescent plaques, symmetrically involving both axilla since last two years [Figure 1]. The eruption had recurred twice with similiar clinical presentation. No other areas were involved.
Histopathology from right axillary lesion demonstrated compact parakeratotic stratum corneum with retention of basophilic keratohyaline granules [Figure 2]. Fungal and bacterial cultures were negative.
Granular parakeratosis was diagnosed and topical calcipotriol successfully cleared all lesions.
