“…Under a transmission electron microscope, amyloid filaments appear straight and long and have a uniform diameter (6 to 7 nm). This is in contrast to colloid in nodular colloid degeneration, which consists of short, wavy, and irregularly arranged filaments that are 3 to 4 nm in diameter3,10,11.…”

Primary Localized Cutaneous Nodular Amyloidosis Following Local Trauma

Primary localized cutaneous nodular amyloidosis (nodular amyloidosis) is a rare and distinct type of amyloidosis, in which amyloid L deposition is limited to the skin and typically manifested as a tumefactive nodule on the acral sites. However, the definite cause of nodular amyloidosis is still unknown. Although it is relatively well known that the amyloid deposits in nodular amyloidosis originate from immunoglobulin light chains secreted by local plasma cells, traumatic injury to the skin has rarely been recognized as a triggering factor of nodular amyloidosis. Herein, we present a case of a 50-year-old male patient with primary localized cutaneous nodular amyloidosis, which occurred after local trauma, and discuss the relationship between traumatic damage and dermal amyloid L deposition.

“…The third form, known as`nodular colloid degeneration', was first described by Labadie in 1927 10 and later by other authors. 11,12 It consists of isolated or multiple plaques and nodules 0´5±5´0 cm in diameter, 11 which are located predominantly on the face but can also develop on the trunk and extremities. Holzberger 13 reported CM of the hands in a group of 28 workers employed in an oil refinery in the tropics.…”

We report a case of adult colloid milium in a 47-year-old mechanic with a long history of professional contact with lubricating oils and of sun exposure. In addition to the typical translucent papules seen on the forehead, there were warty papules on the backs of both hands with unusual histological and ultrastructural features: marked hyperplasia of the epidermis with orthokeratotic hyperkeratosis and papillary deposits of colloid material that were contiguous with the basal layer of the epidermis. The hand lesions caused by occupational exposure to mineral oils and solar radiation represent an occupational variant of adult colloid milium.

“…9,12,13 While the lesions can be clinically and histologically similar to the adult form, ultrastructural examination reveals a striking difference. [14][15][16] The disorder most commonly presents as an isolated nodule on the face, trunk, or scalp and may be up to 5 cm in size. Apparently in the juvenile form there is a hereditary predisposition to sun-induced degeneration of basal keratinocytes.…”
