Immunohistochemical Staining of Pediatric Solitary Angiokeratomas.
The precise etiology and subtype of vessels constituting angiokeratomas is poorly understood. We sought to characterize the vessels by studying prospero-related homeobox gene-1 and D2-40 expression in 22 pediatric solitary angiokeratomas. Routine histologic examination demonstrated a mix of lymph-containing vessels and erythrocyte-filled small vessels. Our results suggest that angiokeratomas may in part be comprised of vessels with lymphatic differentiation.
