Nodular colloid degeneration: distinctive histochemical and ultrastructural features. 1985

J W Patterson, and J K Wilkin, and P F Schatzki

We recently evaluated a patient with a unique form of nodular colloid degeneration. Lesions consisted of pruritic, purpuric plaques involving the upper and lower extremities and the neck. Examination of a biopsy specimen revealed large, fissured masses of amorphous material in addition to solar elastosis. The amorphous material showed negative reactions to stains for amyloid, and other histochemical studies showed results similar to those for colloid milium. The amorphous masses demonstrated a marked positive reaction to the Verhoeff-van Gieson stain for elastin. Electron microscopic examination revealed masses of degenerated elastic tissue bordered by fibrillar material that resembled amyloid morphologically. We believe this case represents a nodular form of solar degeneration with clinical and histologic resemblances to both colloid milium and cutaneous amyloidosis.

D000686	Amyloidosis	A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits.	Amyloidoses
D001706	Biopsy	Removal and pathologic examination of specimens from the living body.	Biopsies
D012872	Skin Diseases, Vesiculobullous	Skin diseases characterized by local or general distributions of blisters. They are classified according to the site and mode of blister formation. Lesions can appear spontaneously or be precipitated by infection, trauma, or sunlight. Etiologies include immunologic and genetic factors.
