A two-day-old full-term male baby born out of nonconsanguineous marriage was brought to Dermatology OPD with complaints of black dots over the left leg. Examination revealed multiple dilated follicular openings filled with black plugs resembling comedones over hypopigmented skin distributed in groups over the right leg extending from upper thigh till ankle arranged linearly in blaschkoid pattern [Figure 1 and Figure 2].

A diagnosis of nevus comedonicus(NC) was made. Examination and appropriate investigations were done to rule out the involvement of central nervous system, skeletal and ocular involvement, thus excluding NC syndrome.[1] NC is a rare hamartoma derived from pilosebaceous unit, frequently affecting face, neck, trunk and upper limb while the involvement of lower limb as seen in this baby is uncommon.[2]
