Description : Confluent and reticulated papillomatosis is a dermatologic disorder characterized
by onset in the teenage or young adult years of hyperkeratotic 1- to 2-mm papules
that increase in size to 4 to 5 mm and coalesce to form a reticular pattern peripherally
and a confluent pattern centrally. Early papules can be erythematous and later turn
brown. Affected individuals are usually otherwise asymptomatic. The condition is distinct
from acanthosis nigricans and tinea versicolor (infection with the yeast Pityrosporum),
but can appear similar. Microscopic examination of skin biopsy shows epidermal undulation
with hyperkeratosis, squat papillomatosis, and occasional acanthotic downward projections
from the bases of the dells between papillomatous areas. Antibacterial agents such
as minocycline and azithromycin are effective, perhaps due to their antiinflammatory
and immunomodulatory properties (summary by Scheinfeld, 2006).;
