White sponge nevus presenting as genital lesions in a 28‐year‐old female

Abstract: A case is presented of white plaques occurring predominantly on the vulvar mucosa of a 28-year-old female diagnosed as white sponge nevus (WSN). WSN is a rare, autosomal dominant disorder involving mucous membranes. It predominantly affects the oral mucosa; however, it has been reported to rarely involve extraoral mucosal sites. In this case, histology and family history were key features leading to the correct diagnosis. WSN is an extremely rare cause of vulvar leukoplakia, yet it is important to recognize to… Show more

“…Clínicamente se suele manifestar por la aparición de mácu-las y placas blancas, queratósicas, bilaterales y simétricas en la mucosa oral, sobre todo en la mucosa yugal. Con menos frecuencia puede aparecer en la mucosa genital, digestiva y de la vía aérea 1, [3][4][5] . Estas lesiones están normalmente bien delimitadas respecto la mucosa normal circundante, tienen estriaciones y son relativamente gruesas.…”

“…Otras alteraciones histológicas son: hiperqueratosis, acantosis y elongación de las crestas interpapilares 1 , que podemos encontrar en casi todas las lesiones inflamatorias y congénitas. Además aparecen condensaciones eosinófilas perinucleares 1,4 , por la agregación anómala de los tonofilamentos de la citoqueratina 4 .…”

“…White sponge nevus (WSN; OMIM 193900) is a rare autosomal dominant disorder that affects the non‐keratinised stratified squamous epithelium. While WSN is usually seen in the oral mucosa, other extra‐oral sites, such as the nasal, oesophageal, laryngeal and anogenital mucosa, may also be involved . The lesions are characterised by white, thick, spongy plaques, which have a corrugated and velvety surface that can be peeled away from the underlying tissue.…”
