Actinic Granuloma of the Conjunctiva

American Journal of Dermatopathology, 1992
Few cases of actinic granuloma of the conjunctiva have been reported. A 39-year-old woman developed a pinguecula. A biopsy study revealed actinic granuloma histopathologically. This case is an example of the interface between dermatology and other fields, and helps to confirm the existence of actinic granuloma of the skin as a distinct entity.

Actinic Granuloma of the Conjunctiva

American Journal of Ophthalmology, 1983
Actinic granuloma is a condition showing actinic elastosis accompanied by a chronic inflammatory cell infiltrate and multinucleated giant cells absorbing elastotic fibers. 1 It differs from granuloma annulare by the absence of necrobiotic collagen and palisading histiocytes.

Is actinic granuloma a specific condition?

American Journal of Dermatopathology, 1979
Evidence is presented that actinic granuloma is not a specific connective tissue disorder as it is thought to be by O'Brien. Granulomatous inflammation does not result simply from a response to elastotic fibers, but is a consequence of primary pathologic processes that are unrelated to damaged elastotic material.

Actinic Granuloma

Archives of Dermatology, 1986
Two cases of actinic granuloma are described with emphasis on distinctive clinical and histopathologic features, including immunoperoxidase staining for lysozyme and immunophenotyping of mononuclear leukocytes. Actinic granuloma presents in chronically sun-damaged skin as normally colored to erythematous papules that coalesce to form centrifugally ...

Actinic granuloma. An ultrastructural study of two cases

Journal of Cutaneous Pathology, 1984
Ultrastructural findings in 2 eases of actinic granuloma are presented. The changes observed at the periphery of the lesion and in the elastic fibers, with early stage of damage, were similar to those described in actinic elastosis. Later, an histiocytic reaction which was apparently directed against damaged elastic fillers was observed.

Actinic Granuloma of the Conjunctiva

Archives of Ophthalmology, 1984
The key histologic feature of pingueculas is the presence of actinic elastosis of the conjunctival connective-tissue fibers. We describe a patient who had a pinguecula that, on pathologic examination, exhibited a prominent foreign-body giant-cell reaction in association with the elastotic fibers.

Annular elastolytic giant cell granuloma-actinic granuloma?

Clinical and Experimental Dermatology, 1996
A 56-year-old woman with annular elastolytic giant cell granuloma is reported. She had annular, slowly growing lesions on sun-exposed areas and the dorsum of one foot. Biopsies from both areas revealed a mid-dermal inflammatory infiltrate with many giant cells engulfing elastic fibres.

Is Actinic Granuloma Really Granuloma Annulare?

Archives of Dermatology, 1986
In 1975, O'Brien 1 described actinic granuloma and indirectly proposed criteria for diagnosis: (1) Annular, slowly enlarging plaques develop on exposed, weather-beaten skin of patients at least 30 or 40 years of age. (2) Elastotic material is present within giant cells, and the inflammation is granulomatous.

Actinic granuloma successfully treated with acitretin

International Journal of Dermatology, 2004
Actinic granuloma is a rare skin disorder that develops in an area of actinic elastosis. The pathogenesis of the disease is obscure but the most accepted hypothesis implicates the solar radiation as the triggering factor. Typically the disease presents in middle-aged individuals with significant past sun-exposure and involves mainly the sun-exposed ...

Actinic Granuloma is a Unique and Distinct Entity

The American Journal of Dermatopathology, 2002
Since the initial description of actinic granuloma (AG), debate has continued over whether it should be considered a specific condition or simply granuloma annulare (GA) located in sun-exposed areas of skin. We conducted a case-control study to clarify this issue.
