Coexistence of Lichen Sclerosus and Morphea in a Single Vulvar Lesion.

Lichen sclerosus (LS) and morphea are chronic inflammatory disorders with overlapping clinical and histopathological features, often complicating diagnosis. While the co-occurrence of LS and morphea as distinct lesions in the same patient is well documented, their overlap within a single lesion is rare, especially in genital regions. Herein, we present a case of a 60-year-old female with coexisting LS and morphea in the genital region, exhibiting features of LS while demonstrating histological characteristics of both. This case underscores the diagnostic challenges and provides further support for the possibility that LS and morphea may represent varying manifestations within a shared disease spectrum.
