Quiz question

What is this condition and what is the etiology?

A 67‐year‐old morbidly obese man (BMI 53), suffering from noninsulin dependent diabetes, presented himself with a 1‐year history of enlarged and asymptomatic papules on both popliteal areas. Physical examination revealed several confluent, partially hyperkeratotic and verrucous cobblestone‐like papules and nodules on both popliteal areas. (see figure 1). Clinical and histological findings supported the suspicion of papillomatosis cutis lymphostatica (PCL). Papillomatosis cutis lymphostatica is benign and an unusual sequela to primary lymphedema 1, 2. Papillomatosis cutis lymphostatica can also result secondary to conditions related to damage of lymphatic vessels, including diabetes. Papillomatosis cutis lymphostatica can damage skin and increase the risk of skin infections 1. Differential diagnosis includes nodular pretibial myxedema, lymphedema, etc. Treatment options are limited to compression, topical ointments, and surgery. The patient was treated successfully with compression and CO2 laser excision 1.
