To the Editor.—
We report a case of lichen sclerosus et atrophicus (LSA) with an asymptomatic, grouped, delled pattern that we feel is unique and have called corymbiform LSA.
Report of a Case.—
A 43-year-old woman was seen for evaluation of asymptomatic lesions of her left shoulder. She stated that these had progressed over the past six months with new lesions forming and old lesions resulting in flattened whitish areas. There was no history of trauma, vaccination, or infection.
Results of Physical Examination.—
On the left shoulder, there were groups of punctate pits surrounded by a narrow, hypopigmented zone devoid of skin markings. As the lesions evolved, hypopigmented, atrophic macules remained. No lesions were noted elsewhere, including on the oral mucosa and the vulva.
There were confluent hyperkeratosis and follicular plugging, with thinning of the epidermis. Homogenization of the upper part of the dermis and a mild periappendage
