A 40-year-old female presented with asymptomatic grouped papules behind the right ear for 1 year. There was no previous history of local trauma or application of any topical medication. On examination, multiple grouped white to yellowish papules, varying in size from 1 to 3 mm, were seen on an erythematous plaque on the right retroarticular region [Figure 1a].
- (a) Multiple grouped white to yellowish papules of varying sizes on an erythematous plaque on the right retro auricular region, (b) multiple yellowish- white cysts (green arrow) and a few comedo like openings on an erythematous background (DermLite DL4, ×10 magnification, polarised mode) (c) multiple keratin cysts (red arrow) with adjacent dermis showing lymphocytic infitrate (haemotoxylin and eosin, ×100).
Dermoscopy showed multiple yellowish-white cysts of varying sizes on an erythematous background [Figure 1b]. Histopathology showed multiple epidermal cysts in the dermis lined by thin stratified squamous epithelium with lamellated keratin in the cyst cavity [Figure 1c].
A diagnosis of milia en plaque was made. In view of the absence of any preceding trauma, use of topical or systemic drugs, and inflammatory skin diseases, it was classified as a primary type of milia en plaque. Complete resolution of the lesion with residual pigmentation was achieved with electrodessication.
