BACKGROUND: Localized lymphedema is a nonneoplastic condition associated with obesity and predominantly involving the legs. This condition has distinctive clinical and histologic features and only rarely has been mentioned in the dermatologic literature.
OBJECTIVE: We sought to evaluate the clinical and histopathologic features.
METHODS: The clinicopathologic features in patients with localized lymphedema of the genital region were studied.
RESULTS: We identified 18 patients with localized lymphedema clinically presenting as large polypoid or verrucous lesions. The patients were 5 men and 13 women with a mean age of 46.5 years. Twelve patients were obese at diagnosis. Thirteen patients presented with tumors involving the vulva, 4 patients with tumors in the penis and scrotum, and 1 patient with scrotal and pubic lesions. Histologically, all cases showed marked dermal edema along with dilated lymphatic spaces, fibroplasia, and verrucous epidermal changes (papillomatous and hyperplastic epidermis).
LIMITATIONS: Only 18 cases were included in our study.
CONCLUSIONS: This condition is an uncommon and recently described entity that could potentially be clinically and histologically misdiagnosed as a neoplasm; thus, it needs to be included in the differential diagnosis of polypoid and verrucous skin tumors with extensive dermal edema and fibroplasia.
