ma·lig·nant a·troph·ic pa·pu·lo·sis

a cutaneovisceral syndrome characterized by pathognomonic umbilicated porcelain-white papules with elevated telangiectatic anular borders, followed by the development of intestinal ulcers that perforate, causing peritonitis; arterioles in the lesions are occluded by thrombosis without inflammatory cells, leading to infarction, progressive neurological disability, and death.

malignant atrophic papulosis

a form of cutaneous lymphocytic vasculitis. The skin disease shows erythematous papules with characteristic porcelain-white centers and elevated borders.

Malignant atrophic papulosis

malignant atrophic papulosis

A rare, often multisystem disease affecting small blood vessels of the skin, gastrointestinal and genitourinary tracts, central and peripheral nervous systems, heart, lungs, eyes, pancreas, adrenals, and kidneys, which is characterised by proliferation of the vascular intima and thrombosis, and infarction of the regions supplied by the involved arteries.

Clinical patterns
• Malignant systemic form—affects multiple organs and typically causes death within 2 years of presentation due to focal necrosis and perforation of the gastrointestinal tract.
• Benign cutaneous form—limited to the skin.

MAP has been consistently resistant to treatments, including corticosteroids, MTX, sulfonamides, tacrolimus, warfarin, etc.
